Android Question Broadcast Receiver API > 25

[marcoseinco]

I want to receive broadcast intents in my app. I've tested broadcastreceiver library, and worked fine in the demo example, but when I add to my app with api 33, it doesn't work.
So I'm testing with new module of receiver type, adding the manifest, but I don't get the receive envent.
I've seen that the app receive broadcast with targetSdkVersion = "25" but with targetSdkVersion > 25, event Receiver_Receive don't fire up.
What is the problem?


this is my manifest.xml:

'This code will be applied to the manifest file during compilation.
'You do not need to modify it in most cases.
'See this link for for more information: http://www.b4x.com/forum/showthread.php?p=78136
AddManifestText(
<uses-sdk android:minSdkVersion="5" android:targetSdkVersion="33"/>
<supports-screens android:largeScreens="true"
    android:normalScreens="true"
    android:smallScreens="true"
    android:anyDensity="true"/>)
SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
'End of default text.
AddPermission(android.permission.RECEIVE_ULTRASONIC_API)
AddReceiverText(myReceiver,
<intent-filter>
    <action android:name="com.my.app.CUSTOM_INTENT" />
</intent-filter>)

and this is myReceiver.bas module:

Sub Process_Globals
   
End Sub

'Called when an intent is received.
'Do not assume that anything else, including the starter service, has run before this method.
Private Sub Receiver_Receive (FirstTime As Boolean, StartingIntent As Intent)  
    Log(StartingIntent)
End Sub

I want to receive broadcast intents in my app

from whom?

I don't think that the behavior depends on the targetSdkVersion. The problem is somewhere else.

Make sure to run your app in RELEASE mode.

Yes, I run in release, and I only change targetSdkVersion and stop working.

This is the code I execute on Android Studio app:

 Intent intent = new Intent();
 intent.putExtra("notice",simp);
 intent.setAction("com.seinco.broadcastreceiver.CUSTOM_INTENT");
 sendBroadcast(intent);

As you can see is very simple.

1.

SetReceiverAttribute(myReceiver, "android:exported", true)

If it still doesn't help then it is probably related to the new background restrictions: https://developer.android.com/devel...kground-tasks/broadcasts/broadcast-exceptions
2.
You need to set the target class in your Java code:

intent.setPackage("target.app.package.just.exampe.change.it")

I've added a menu item in the B4A app to self send an intent to the same app.
And guess... If I use sdk 25 works fine, and if I change to 33 fail!
I send you the B4A app to check.
The device where I'm testing have android 9.

Thanks Erel, the problem was that with sdk > 25, you have to add intent.setPackage, not only action.
