B4A Library AppUpdating - automate apps updating from a webserver

Status
Not open for further replies.
Important note: since all the changes made to the Android OS the original code is to be considered outdated. Thanks to @Yayou49 you may find at post#290 a version of the class usable on Android 6+ versions.

Note: version 1.25 breaks existing code so, please, read changelog in post #60 below.


Hi all,

this is my first contributing lib to this great NG.
How do I dare to publish such a low-grade stuff in an area where generally you may find real masterpieces of programming? Well, to be honest, I hope in your help to upgrade my work to a status of "ready-made solution" for those who prefer to run their own webservers where to publish apps.
Secondly, I was asked (both privately and publicly) to overcome my legitimate embarassment and go on with the publication. So, here we are: AppUpdating 1.18!

Note: any valid code fragment comes from some other thread, while all the bad stuff is entirely mine ;-)

Please find attached both the library as is (yes, it works out of the box) and its source code.

On a following post I'm gonna describe the lib in greater detail and show how to use it.

Thank you. I did include a few suggestions from the thread for the final release of AppUpdating 1. It's ready since a few weeks but I'd like to briefly test it before submitting to post#1.
Hopefully I'll have some spare time before Xmas.

Just a heads up my Pixel is running 8.1, and AppUpdating is still working fine, although I have recompiled it recently.

Hi Walter,

did you read post #242 and those soon following it? You should recompile AutoUpdating from its source with your copy of B4A to overcome the differences on internal libraries' versions.

I'm happy to give you (with UDG authorisation) my updated class cl_appupdate (attached).
This version manage the new version of sdk (26)

It has been done with a part of Erel's code about Fileprovider.
I've tested it with my phone (Android 7.0 SdkVersion 24) and it works fine !

So:

1: add to your manifest
B4X:
AddManifestText(<uses-permission
    android:name="android.permission.WRITE_EXTERNAL_STORAGE"
    android:maxSdkVersion="18" />
)

AddApplicationText(
  <provider
  android:name="android.support.v4.content.FileProvider"
  android:authorities="$PACKAGE$.provider"
  android:exported="false"
  android:grantUriPermissions="true">
  <meta-data
  android:name="android.support.FILE_PROVIDER_PATHS"
  android:resource="@xml/provider_paths"/>
  </provider>
)
CreateResource(xml, provider_paths,
   <external-files-path name="name" path="" />
)
AddPermission(android.permission.REQUEST_INSTALL_PACKAGES)

2: Add in your starter class:

B4X:
Sub Process_Globals
    Public rp As RuntimePermissions
    Public SharedFolder As String  
End Sub

Sub Service_Create
    SharedFolder = rp.GetSafeDirDefaultExternal("")
End Sub

3: update the cl_appudate


Thanks to UDG for his time.

Is there a way to make app update in 'silent' mode ... so without asking user, and that app is updated and restarted ?
If not with 'normal' phone, is it possible wit rooted ones ?


Maybe this question was already asked and answered ... but I can't found it ...

Unfortunately Android doesn't allow it, at least for non-rooted devices. I don't know if it can be done on rooted ones. Sorry.

Android JAR is: C:\Android\platforms\android-26\android.jar
B4A ver is: 7.8

Can someone help me where am'I wrong?

Thanks
Clemente

Ran into a new problem with this lib.

For some weird reason the lib is hanging and not firing the UpdateComplete when ---- AppUpdating.ReadCurVN is called.

Only on one particular app. I checked everything else. Odd...

Edit: I actually traced it down to this not working:

B4X:
CallSub(Callback,Event&"_UpdateComplete")

So I think its a bug in B4A.

Turning off log filtering in logcat, I get this:

---- AppUpdating.ReadCurVN
Current Version: 1.30
sendKeyguardVisibilityChanged(true)
ignoring event: update_updatecomplete

Yikes! thoughts?

Recompiling with CallSubDelayed did not work either.

Edit: Nevermind. I was doing my update check in the Activity_create thread which will never work.

I have to release that thread and then use a timer or something, and that worked.
