Android Tutorial B4A Change Log (versions history)

Erel · Jul 6, 2012

v8.30 - June 12, 2018: https://www.b4x.com/android/forum/threads/b4a-v8-30-has-been-released.94044/

Resumable subs in debug mode are optimized in the same way other subs are optimized. You can see the difference in this video:
Starter service is never destroyed until the process is killed - if you carefully read the automatic foreground notifications tutorial then you should be aware to a significant behavioral change in Android 8+. The OS kills services while the app is in the background. In previous versions the OS never killed specific services (only the complete process). This change made it much more difficult to work with the starter service as you could no longer assume that the starter service is running.
Starting from B4A v8.3 the starter service will never be paused until the process is killed. Internally it switches from the service context to the application context.
Several other important debugger optimizations.
Bit.ArrayCopy method. Same as ByteConverter.ArrayCopy.
New File methods: CopyAsync, Copy2Async, ReadBytes, WriteBytes and ListFilesAsync.
Support for Java 8 jars and AARs.
Ctrl + Click on class types and custom types.
Autocomplete improvements.
Autocomplete in CallSub methods:
B4A Sdk Manager v3.27 - Supports Java 10.
Files can be added to groups directly.
For loops optimization (in release mode).
BitmapCreator v3.60 is included as an internal library.
xCustomListView v1.63 is included as an internal library.
XUI v1.70 is included as an internal library. This is a large update to XUI library with support for text measurements and other features.
Phone.ShellAsync - Asynchronous version of Phone.Shell.
Bug fixes and other minor improvements.

v8.00 - March 20, 2018: https://www.b4x.com/android/forum/threads/b4a-v8-00-beta-has-been-released.90536/

I'm very happy to release B4A v8.0. This update includes many important improvements and makes it simpler to target the latest versions of Android.

(image source: android.com)

As explained in this tutorial, all apps will soon need to target sdk version 26 (Android 8). This is a new policy of Google and it has many consequences for app developers. Many of the improvements in B4A v8.0 help developers with this task.

Improvements:

The process of starting the app from the background was rewritten to comply with targetSdkVersion 26 requirements.
Push notifications and other features that cause apps to start from the background should be more reliable due to changes in the way services are started. A wake lock is automatically held when a receiver receives an intent. The wake lock is released when the service starts.
Automatic foreground mode: https://www.b4x.com/android/forum/threads/automatic-foreground-mode.90546/
Notification object rewritten to work with targetSdkVersion 26. In most cases you don't need to change anything. Notification.SetInfo or Notification.SetInfo2 should be the last calls before you show the notification.
Notification.SetInfo / SetInfo2 accept CharSequences so it can work with CSBuilder.
StartServiceAt / StartServiceAtExact rewritten to work with targetSdkVersion 26 and they are now more reliable.
Notification.Initialize2 - Allows to set the notification channel importance level.
Better support for AAR libraries: jni folders (native libraries) are handled properly, assets and resources from internal jars are added to the project.
#AdditionalJar with ReferenceOnly - Allows referencing jars that are only used as a reference during compilation. This is required for more complex libraries such as DJI library.
Signing key size is explicitly set to avoid issues with newer versions of Java.
B4A Sdk Manager v3.25 - Bug fixes and support for Google based AVDs.
Screenshot tool modified to work with latest versions of Android SDK.
MediaPlayer.IsInitialzied method.
Manifest editor macros - Macros can be added to libraries or zip files. For example to set a light theme based on Android version:
B4X:
```
CreateResourceFromFile(Macro, Themes.LightTheme)
```
Unless you are setting a custom theme then it is recommended to use either Themes.LightTheme or Themes.DarkTheme.

Firebase push notifications:
B4X:
```
CreateResourceFromFile(Macro, FirebaseAnalytics.GooglePlayBase)
CreateResourceFromFile(Macro, FirebaseAnalytics.Firebase)
CreateResourceFromFile(Macro, FirebaseNotifications.FirebaseNotifications)
```
https://www.b4x.com/android/forum/threads/new-feature-manifest-macros.90398/#content
Custom class templates - Class templates can be added to libraries.
For example if you add the XUI library to your project then you will have an option to add a custom view based on XUI:

Libraries can include multiple templates and any library can include templates.
#SignKeyAlias attribute - Allows overriding the default signing key alias.
Firebase, xCustomListView and KeyValueStore (2) are internal libraries.
Libraries deprecation messages in the IDE:
Fix for a very long standing issue where the activity code could have been executed while the activity is paused which leads to a hard to reproduce NullPointerException.
BADoclet (tool to generate libraries XML) v1.07 - adds support for custom class templates.
Other bug fixes and minor improvements.

Backward compatibility notes

Notification.SetInfo or SetInfo2 should be the last calls before you use the notification. Note that standard notifications created with previous versions of B4A will not work at all on Android 8+ when targetSdkVersion is 26+.
Adding a service, other than the Starter service, will add the WAKE_LOCK permission. This is a non-dangerous permission.
As mentioned above a wake lock is held automatically when a service is started from the background and until Service_Start is called. You can remove this permission with:
B4X:
```
RemovePermission(android.permission.WAKE_LOCK)
```
Everything will still work, however the service might fail to start from the background in some cases.

v7.80 - December 20, 2017: https://www.b4x.com/android/forum/threads/b4a-v7-80-has-been-released.87467/

Several important components were rewritten to provide more features and better performance:

Visual designer properties grid
Visual designer views tree
Modules tree (new component)
Files tree

The major improvements are:

Code modules can be loaded from other folders and can be easily shared between projects (including projects targeting other platforms): https://www.b4x.com/android/forum/threads/b4x-modules-files-groups-and-folders.86587/
Modules and file tree support grouping:
Modules are monitored for external changes.
Files tree shows the files icons and allows opening the files with external editors: https://www.b4x.com/android/forum/threads/b4x-external-editors.86592/
Modules, files and views can be renamed directly from the relevant tree.
Full support for drag and dropping files and modules, including support for dragging multiple items.
B4A services and activities can be shared with B4J.
New options when adding modules:

Copy to folder: Copies the module to the project folder (same as the current behavior).
Link - relative path: Adds a link to the module with a relative path. Useful when the folder is under or close to the project folder.
Link - absolute path: Adds a link to the module with an absolute path.
Deleted files are moved to the recycle bin.
Properties grid and views tree can be filtered.
Properties grid is much faster and includes new types of editors:
B4A Sdk Manager is included in the IDE:
Support for downloading maven resources from Google online repositories. This is an important improvement as Google no longer updates the offline repositories.
Java 9 is supported.
WebView.ZoomEnabled hides or shows the zoom controls.
Better error handling in CallSub calls.
Fix for potential race condition in AsyncStreams.
Better handling of edge cases where the Activity life cycle events are called multiple times.
CallSubDelayed doesn't raise an error if the target sub is missing. This makes it safer to use CallSubDelayed for raising events,
Better support for version control. Files are only written when the contents are actually changed.
The modules internal attributes are sorted in lexicographical order to reduce random changes.
XUI library is now an internal library.
Debugger hover window is resizable.
Add New Modules / Existing modules menu items in modules tree.
Code editor color picker is based on the designer color picker.
Open file with default program in Files tree. Also works with double click.
Support for opening multiple files at once.
Better handling of locked files.
Manifest editor replacements are applied to resources created with CreateResource.
Bug fixes and other minor improvements.

v7.30 - August 21, 2017: https://www.b4x.com/android/forum/threads/b4a-v7-30-has-been-released.82971/

Localizable IDE. Currently available in 23 languages.
Bitmap type:
- Resize / InitializeResize / LoadBitmapResize - Similar to LoadBitampSample but better. Allow setting the image to a specific size while optionally maintaining the aspect ratio and the bitmap scale.
  Tutorial: https://www.b4x.com/android/forum/threads/loadbitmap-loadbitmapresize-loadbitmapsample.82693/
- Scale property - Returns the bitmap scale.
- Rotate / Crop methods.
New ResumableSub type. Makes it simple to return values from resumable subs and to wait for resumable subs to complete.
https://www.b4x.com/android/forum/threads/b4x-resumable-subs-that-return-values-resumablesub.82670/
EditText - SelectionLength and SetSelection methods.
SingleLine property added to Label, Button and other views that inherit from Label.
Ellipsize property:
View.SetVisibleAnimated affects the alpha level and the Visible property.
Warnings for illegal methods in Process_Globals.
Async dialogs are supported in classes.
Compiled libraries can reference AAR libraries.
Icon picker - aliases added to FontAwesome icons.
Auto complete and auto format improvements.
PhoneCalls (Phone library) - READ_CALL_LOG permission removed. It was added by mistake in a previous update.
Canvas.AntiAlias property to enable or disable antialiasing.

View.SetBackgroundImage returns a BitmapDrawable object. This allows changing the Gravity to CENTER instead of the default FILL value.

B4X:

'load a background image while maintaining its aspect ratio.
Dim bd As BitmapDrawable = Activity.SetBackgroundImage(LoadBitmapResize(File.DirAssets, "bg.png", Activity.Width, Activity.Height, True))
bd.Gravity = Gravity.CENTER

OkHttpUtils v2.61 - Job.GetBitmapResize and PATCH, HEAD and DELETE requests.
Improvements to the layouts loader engine. It is more flexible with the variables types and a bit faster. This feature will allow to add cross platform views types.
Administrator v1.10 - Adds support for owner apps. This update requires a change in the manifest editor. Instructions and copy of previous version are available here: https://www.b4x.com/android/forum/threads/device-administrator-library.19208/#content
Bug fixes, including an important debugger bug, and other minor improvements.

v7.00 - May 24, 2017: https://www.b4x.com/android/forum/threads/b4a-v7-00-has-been-released.79908/

This update includes the new resumable subs feature. This is the most important programing language improvement since the addition of classes in B4A v2.
It makes it much simpler to manage asynchronous tasks.

Quoting @johndb :

This version sure does clean up the code without jumping from sub to sub to sub to ... to handle asynchronous processing in a very clean manner. This and the previous "multi-dex" features in my opinion are game changers for B4X.

Improvements:

Resumable subs - Wait For / Sleep: https://www.b4x.com/android/forum/threads/resumable-subs-sleep-wait-for.78601/#post-498072
[B4X] SQL with Wait For
[B4X] OkHttpUtils2 with Wait For
Async dialogs: https://www.b4x.com/android/forum/threads/doevents-deprecated-and-async-dialogs-msgbox.79578/
Variables and subs renaming based on the Find All References feature.
Quick search supports replacing including replacing in all modules.
Icon picker - Filter field supports filtering by hex code.
Starter service better handles cases where the process is started by multiple intents.
CSBuilder.Image adds an underscore instead of space to fix an issue with multiline strings.
Application_Error - Fixed a compatibility issue with Android 2.2.
PhoneCalls - READ_CALL_LOG permission added. This is a new requirement.
Sender is set when raising events with CallSub or CallSubDelayed from classes.
Debugger improvements related to deployments of large projects. It is recommended to upgrade B4A-Bridge to v2.31: https://play.google.com/store/apps/details?id=anywheresoftware.b4a.b4abridge&hl=en
DoEvents is deprecated. A warning will appear when using it (see the async dialogs tutorial). Note that it is still supported, exactly as before.
SQL library updated to make it simpler to use with Wait For.

Notes:
- B4A compiled libraries with service modules need to be recompiled.
- Java 8 is required (Tools - Configure Paths).

v6.80 - March 1, 2017: https://www.b4x.com/android/forum/threads/b4a-v6-80-has-been-released.76761/

CharSequence as internal type. Allows showing rich text in many places such as: Labels, toast messages, dialogs, ListView and others.
CSBuilder - Simplifies the creation of rich text CharSequences: https://www.b4x.com/android/forum/threads/charsequence-csbuilder-tutorial.76226/#content
Support for MultiDex - With MultiDex enabled there is no limit to the number of methods or fields. This issue is important for large projects that reference many third party libraries. https://www.b4x.com/android/forum/threads/multidex-solves-the-too-many-methods-error.76431/
OkHttp updated and is now based on OkHttp v3.50.
Many improvements to B4A-Bridge:
- Auto discovery - Devices running B4A-Bridge are discovered automatically and are listed in the devices list with their names.
- Logs - The logs implementation was rewritten. Logs reading with B4A-Bridge is more stable and it is also possible to read the unfiltered logs (limited to the running process).
- #BridgeLogger attribute - When set to true, logs will be available in release mode as well as debug mode.
- Landscape layout.
- Download progress bar.
- File Explorer menu shortcut.
Find all references (F7) finds references in layout files and CallSub methods.
Typeface.FONTAWESOME / MATERIALICONS constants.
Icon picker - Filter field and icons tool tips:
CallSubUtils is included as a library.
Menu click event implementation changed to avoid issues with modal dialogs.
Release and Debug compilation symbols are supported in the manifest editor and designer script.
Export as zip keeps the original dates.
Other minor improvements and bug fixes.

1. Make sure to update to B4A-Bridge v2.30+: https://play.google.com/store/apps/details?id=anywheresoftware.b4a.b4abridge
2. If you are using the Dialogs library then you need to update to v2.94: https://www.b4x.com/android/forum/threads/dialogs-library.6776/

v6.50 - December 12, 2016: https://www.b4x.com/android/forum/threads/b4a-v6-50-has-been-released.74051/
FontAwesome and Material Icons fonts with more than 1500 icons are now integrated in the IDE:

You can see more information here: https://www.b4x.com/android/forum/threads/b4x-fontawesome-material-icons-fonts.72908/

- New auto format feature:

The formatting happens when you paste code (can be disabled) or when clicking on Alt + F. In the later case the enclosing sub will be formatted or the selected code if the selected text is not empty.

Other improvements:

Block autocomplete improved. It better handles nested blocks and also completes #If and #Region keywords.
Manifest editor support for #Region blocks.
Service can extend custom classes with the #Extends attribute. This makes it simpler to create libraries that extend services. A modified version of NotificationListener library is attached as an example.
View.Padding property. Sets the distances between the view's borders and the content. It can also be set in the designer.
PhoneSensors.Accuracy and TimeStamp properties. Return the values of the current event.
OkHttp v1.02 - Fixes an issue where headers were not available when the response status code was not 2xx.
Application.Icon property - Returns the application icon as a bitmap.
Jumping to a bookmark moves the bookmark to the center of the editor.
B4ABuilder - The output parameter supports passing the full path instead of just the APK name.
Note that you need to quote the parameter like this if there is space in the path:
B4X:
```
B4ABuilder -task=Build "-output=C:\APK Folder\MyApp.apk"
```
Bug fixes and other minor improvements.

There were changes in the layout files format. Layouts saved in v6.50 cannot be loaded in previous versions of B4A.

v6.31 - November 1, 2016: https://www.b4x.com/android/forum/threads/b4a-v6-31-has-been-released.72555/

There are many IDE related improvements in this update.

The docking and layout features are based on a new and improved framework. Floating code editors behave as regular windows.
Documentation tool tips while hovering over code elements:

View attachment 48045
Copy links in the tool tips that allow copying code examples.
Support for bookmarks:
New themes.
URLs in comments and strings are ctrl-clickable.
Class and module level documentation (taken from Process_Globals or Class_Globals subs).
Quick search shows a list of recent searches.
Designer uses the multiline text editor for text properties.
Unused libraries warning.
Debugger related improvements.
Custom views support "nullable colors". The default value of such fields looks like:

This is an important feature as in many cases it is better not to set any color and use the system default.
Rect.Width and Height properties.
Service_TaskRemoved event added to the Starter service. This event is raised when the user closes the app from the recent apps list. This is an Android 4+ event.
FloatLabeledEditText - Text and hint colors can be set in the designer.
Regex.Replace / Replace2 - Regular expression replacement.
(Java) The Tag property is set when calling CustomView.replaceBaseWithView2 (replaceBaseWithView is deprecated).
_onkeydown and _onkeyup inline Java hooks.
Other bug fixes and minor improvements.

v6.00 - June 20, 2016: https://www.b4x.com/android/forum/threads/b4a-v6-00-has-been-released.68112/

New features and improvements:

Compilation of artifacts from Android SDK maven repositories. This allows the compiler to include the classes and resources required by the referenced "feature".
Firebase backend services. The following services are supported (more will be added in the future):
- Analytics & crash reports: https://www.b4x.com/android/forum/threads/firebaseanalytics-analytics-crash-reports.67708/
- Notifications / Push messages: https://www.b4x.com/android/forum/t...-messages-firebase-cloud-messaging-fcm.67716/

Runtime permissions: https://www.b4x.com/android/forum/threads/67689/#content
Debugger works properly with applications with android:targetSdkVersion set to 23.
CreateResourceFromFile manifest editor command: converts the Json file from Google services to a resource file.
Activity_PermissionResult event: raised after a call to RuntimePermissions.
Warning engine and debugger were improved.
B4A-Bridge was updated to use runtime permissions: https://play.google.com/store/apps/details?id=anywheresoftware.b4a.b4abridge&hl=en
Bug fixes and other minor improvements including:
- The B4A-Bridge indicator in the status bar is clickable. Toggles the connection state.
- Find subs and modules (Ctrl + E) can also be used to jump to a line number. Click Ctrl + E, enter the line number and press enter.
- Virtualization of TreeViews in the designer can be disabled by editing the INI file. It is a workaround for a .Net Framework issue that can cause the designer to freeze.

This version is backwards compatible with older versions of B4A.
It is recommended to switch from referencing the complete google play services to referencing the required features. Overall it is simpler as the #AdditionalRes and #ExcludeClasses are no longer required.
Google Maps: https://www.b4x.com/android/forum/threads/google-maps.63930
FusedLocationProvider: https://www.b4x.com/android/forum/t...ay-services-fused-location.67748/#post-429215

Android SDK repositories should be installed: https://www.b4x.com/android/forum/threads/integrating-firebase-services.67692/

v5.80 - February 22, 2016 - https://www.b4x.com/android/forum/threads/b4a-v5-80-has-been-released.63858/

Custom views: [B4X] Custom Views with Enhanced Designer Support
With this feature it is much easier to add and configure custom views.
#ExcludeClasses: https://www.b4x.com/android/forum/threads/new-feature-three-birds-with-one-stone.63127/
This attribute makes it simple to exclude classes not required from libraries such as google play services.

CreateResource manifest editor keyword: https://www.b4x.com/android/forum/threads/new-feature-three-birds-with-one-stone.63127/#post-398974
Allows creating XML resource files from the manifest editor.
For example with this code we can use the native light theme based on the Android version:

B4X:

SetApplicationAttribute(android:theme, "@style/LightTheme")
CreateResource(values-v20, theme.xml,
<resources>
  <style
  name="LightTheme" parent="@android:style/Theme.Material.Light">
  </style>
</resources>
)
CreateResource(values-v14, theme.xml,
<resources>
  <style
  name="LightTheme" parent="@android:style/Theme.Holo.Light">
  </style>
</resources>
)

Debugger improvements and fixes. Mostly related to larger projects.
Coarse location permission added to BluetoothAdmin. Required for discovery in Android 6.
The default setting of the holo theme in the manifest editor was removed.
It is recommended to use a custom theme or the device default theme.
The compiler will issue a warning about explicit usage of the holo.theme.
The WYSIWYG designer defaults to material theme on Android 5+.
The READ_LOGS permission was removed from LogCat object. It is not useful since Android 4.1.
The compiler will issue a warning if the targetSdkVersion is missing or if the value is not between 14 to 22.
ViewsEx library - Includes two views implemented as custom views (Switch and RatingBar). The source code of this library is available in the custom views tutorial.
View.Parent - Returns the view's parent.
OkHttp and OkHttpUtils2 libraries are included.
Other minor IDE improvements and bug fixes.

v5.50 - November 11, 2015 - https://www.b4x.com/android/forum/threads/b4a-v5-50-has-been-released.60242/

Advanced optimizations were made to the debugger which make the debugger significantly faster.

Watch Expressions feature (see screenshot above).
The rapid debuggers uses a virtual assets folder. This makes it possible to redeploy only the modified files. This feature makes deployments of large projects with many files much faster.
Visual designer - Views tree performance is significantly better. Views preserve their names when pasting views between layouts.
#AdditionalRes attribute can be used multiple times.
ScrollView.ScrollToNow method (available in HorizontalScrollView as well). Immediately scrolls the ScrollView to the new position.
Quick Search tool (Ctrl + I) - An index based search tool for quick searching (in all modules):
Regions were added to the Find Sub (Ctrl + E) tool.

Great idea. Thank you for taking the time to collect this information.

You are missing v1.90

Thank you all.

Now added and version 1.90. Thanks Erel for tip :sign0098:

Roger Garstang · Jul 6, 2012

Good info, I couldn't find the 2.02 changes anywhere, and the announcement of it I only saw mentioned as a comment in another thread. I had grabbed the beta right before it that wasn't announced either. It is always good to know what changed, so if there are issues in code and a recent change was in that area you can debug easier too.

CharlesIPTI · Jul 6, 2012

Addendum

So what magic do I need to work on my download link to actually FIND the 2.02 version ?

I'm actually running a 2.01 at the moment

pluton · Jul 6, 2012

Erel says in post:

The installer is available in the same link as v2.00.

CharlesIPTI · Jul 6, 2012

Ya tanks

I saw that thanks but somewhere else I notice people were having to EDIT the link to get the current version

my link still says its for 2.00 exe and it downloads 2.01 so thanks again but not what I'm looking for ..

for that matter my same link grabbed the 1.95 version before 2.0 was out so
aslong with what your saying you'd think the link would remain the same and just point to the new version.. Who knows 2.01 might even be 2.02 at this point I don't know...

Erel · Jul 8, 2012

There is no need to edit the link. Your link will download v2.02.

If it was needed I would have wrote it.

Note that this is the wrong place to post about not receiving a link. Future posts will be deleted.

Amalkotey · Jul 8, 2012

Thank you for the information!

carbonsystem · Jul 18, 2012

PhilipBrown · Feb 11, 2015

According to the above, Version 3.8 introduced

Array keyword - The type can be omitted. In that case the array type will be Object. The Array keyword now supports creating empty arrays.

However when I declare an array without specifying the type, eg
Dim arr(3)
I get the warning: Variable declaration type is missing. String will be used. (warning #5)
In fact I can store different types of data in different elements of the array, so I guess the warning is wrong.

I wonder also what is the point of creating an empty array, since one cannot then assign any data to it...

Erel · Feb 12, 2015

The warning is correct.

The new feature means that you can write:

B4X:

JavaObject.RunMethod("some method", Array ("parameter 1", 2))

Before you needed to write:

B4X:

JavaObject.RunMethod("some method", Array As Object ("parameter 1", 2))
