Ai2 uses old versions of androidx.core library, so I had to repackage the classes to fix issues.

Does anyone here know if this extension is available for API 34 or if it is functional for API 34?
I do not know
But you could help to find it out, if you provided a logcat output so we can see what exactly happens
Probably it is only an emulator issue?
Also to test on a device might help...

The damage persists, it does not allow emulation in the companion but when I remove the extension the companion runs normally
I use lottifiles extension. In companion runs the animation well, but when I build the apk and run, this error is happening:
Runtime Error No virtual method append(Ljava/lang/String;)Ljava/lang/AbstractStringBuilder; in class Ljava/lang/StringBuffer; or its super classes (declaration of 'java.lang.StringBuffer' appears in /apex/com.android.art/javalib/core-oj.jar)
Which extension is that? Please provide a link...
This?
Do not post direct links to aix files, instead provide a link to the topic where this extension is published.
Would you mind sharing the apk?
