I'm happy to release B4A v7.30 BETA. This is the first localizable version of B4A.

A big thank you to all the great translators!


This update includes many improvements:

  • Localizable IDE. Currently available in 21 languages.
  • Bitmap type:
  • 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.
    '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
  • New ResumableSub type. Makes it simpler to return values from resumable subs and to wait for resumable subs to complete.
  • OkHttpUtils v2.60 - 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.

Developers who are eligible for a free upgrade will receive an email with upgrade instructions.

Please report issues in new threads.

Where I find the link to download this beta, has not reached my email.

What was the important debugger bug?
There was a bug that in some cases an assignment such as this one:
Dim localvariable As Int = globalvariable
Could have caused localvariable to actually share the same memory with globalvariable. If globalvariable later changed it would have also changed localvariable.
The bug was more reproducable with resumable subs though it was always there.
