Android Question Duplicate Classes in Play Core Libraries

[madrigal115]

Hello
I have encountered a compilation issue in B4A due to duplicate classes in the Play Core libraries downloaded from your site.
com.google.android.play.core.common.IntentSenderForResultStarter is defined multiple times.

• Conflicting versions:
  • core-common 2.0.4
  • core 1.10.3

This causes the following error during compilation:

Type com.google.android.play.core.common.IntentSenderForResultStarter is defined multiple times
Compilation failed

Not enough information here.

Make sure to use latest version of B4A with an updated SDK (download a new one).

Hello Erel,
I am encountering a compilation issue in B4A 13.4 with the latest SDK. The error occurs due to duplicate classes in the Play Core libraries:

This conflict happens when both InAppUpdate and FirebaseAuth libraries are included in the project.
