Version 1.2.10 - ClassCastException in specific devices (Lenovo, Asus)

[beqirajd]

After upgrading to1.2.10 some crashes were reported in:

1. Lenovo Tab M10 FHD Plus
2. Lenovo Tab E10
3. ZenFone 6 (ZS630KL) (WW) / 6Z (ZS630KL) (IN)

with Android Versions 8, 10 and 11.

When my activity class that extends LocalizationActivity is created, this crash occurs:

Do you know what be.a is ? It was obfuscated.

It is obfuscated class. But I only get the error in production app and unfortunately I cannot figure out what the obfuscated fragment is.

You can upload mapping.txt that generated from obfuscate processing in Google Play.

It will help you to retrace mapping the obfuscated class in production to original class name.

Since AndroidX AppCompat has per-app language preferences for backward compatibility. Please migrate this library to AndroidX for more stability, compatibility, and longer support from Google team.

See Migrate to AndroidX guide
