Android Question FLAG_IMMUTABLE or FLAG_MUTABLE

[Saeed Qatari]

How to FLAG_IMMUTABLE or FLAG_MUTABLE in B4A?

 

[agraham]

Ah! - the pending intent problem again. Search the forum but upgrading to B4A 11.80 should fix it.

 

[Saeed Qatari]

I did upgrade but the app crashes when I use SMS Send and shows the error of PendingIntent and setting the FLAG.

Try updating Core library to 11:81 https://www.b4x.com/android/forum/threads/solved-target-sdk-31-widget-crash.142138/post-901738

If you were a very early upgrader to 11.80 try installing it again. A fix was needed in Core.jar which I believe Erel has now added to the installer.

This is only relevant for the issue with home screen widgets.

@Saeed Qatari please post the full error message from the logs, and the relevant code.

java.lang.IllegalArgumentException: com.eltizam3.emoya: Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent.
Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable, e.g. if it needs to be used with inline replies or bubbles.

Looks like Phone.PhoneSMS.Send2 (which is called by Send) uses a PendingIntent and will need the Phone library updated to fix this.

 

[Erel]

I've fixed it for the next version of B4A. In the meantime you should set targetSdkVersion to 30.
This cannot be a Google Play app anyway: SMS and CALL_LOG permissions are no longer available

 

[Saeed Qatari]

Thank you.

Just for info.
The same error occurs when using the library USB, namely at:

usbmanager.RequestPermission(device)
