Android Question [Solved] Licensing Library Crashes With Target SDK 28

RichardN · Sep 19, 2019

I was just updating a legacy application with some AppCompat features before publishing to the Play Store with TargetSDK 28. The application employs the Licensing Library Version 1.21 which I believe is the latest.

If I conditional compile the demo version without the LC library code (demo version) it compiles OK. If I include the LC check in the compile but switch the targetSDK down to 27 it compliles OK.

The combination of Licence Check + TargetSDK 28 crashes on compile.

Does it work if you add this to the manifest editor:

B4X:

AddApplicationText(
<uses-library
      android:name="org.apache.http.legacy"
      android:required="false" />
)
