API 30/android 11 library won't run anymore.

[JimSeker]

Expected behavior

compileSdkVersion 30  

implementation 'org.altbeacon:android-beacon-library:2+'
should run, but fails.

Actual behavior

 java.lang.NoClassDefFoundError: Failed resolution of: Landroidx/localbroadcastmanager/content/LocalBroadcastManager;

Steps to reproduce this behavior

You only need the implementation line and beaconManager = BeaconManager.getInstanceForApplication(this); to cause the failure.

Mobile device model and OS version

Android 11.

Android Beacon Library version

implementation 'org.altbeacon:android-beacon-library:2+' //2.17.1 I think is current version.

note this is fixable by adding implementation 'androidx.localbroadcastmanager:localbroadcastmanager:1.0.0' to module build.gradle file.

@JimSeker did you add 'androidx.localbroadcastmanager:localbroadcastmanager:1.0.0' to your app module or to fetched beacon lib module?

[davidgyoung]

Yes, it is necessary to add implementation 'androidx.localbroadcastmanager:localbroadcastmanager:1.0.0' to your project's build.gradle. You can see an example of this here:

https://github.com/davidgyoung/android-beacon-library-reference-kotlin/blob/master/app/build.gradle#L35

I have made a full kotlin version of the reference app here which includes the above:

I still need to update the Library docs to show this proper setup. A future release will make this unnecessary, but for now it is required.

[JimSeker]

thanks. I look forward to the new release.

Resolved via #1022. If using 2.18-beta or higher (now available on Maven Central as JCenter is going away) you no longer need to include the localbroadcastmanager dependency.
