I updated branch SDK from 4.2.1 to the latest 5.0.4, after I publish these changes to the store I got a long list of ActivityThread crashes on firebase, can anyone tell me how to fix it I check the docs but I didn't find anything

Please check the following log

Fatal Exception: java.lang.RuntimeException Unable to instantiate receiver io.branch.referral.InstallListener: java.lang.ClassNotFoundException: Didn't find class "io.branch.referral.InstallListener" on path: DexPathList[[zip file "/data/app/com.creativeinnovations.mea-NSPFqM2PtXEVqHmKBGyUUQ==/base.apk"],nativeLibraryDirectories=[/data/app/com.creativeinnovations.mea-NSPFqM2PtXEVqHmKBGyUUQ==/lib/arm64, /data/app/com.creativeinnovations.mea-NSPFqM2PtXEVqHmKBGyUUQ==/base.apk!/lib/arm64-v8a, /system/lib64, /product/lib64]]

Thank you in advance

Hey @amer360,

Wanted to follow up on this and see if you were able to resolve the crashes. With the major release of 5+ we introduced new methods of Branch initialization to handle app lifecycle methods which could certainly affect the previous handling.

Hey @jf-branch, this issue still persists in the latest Branch SDK. See logs below:

Fatal Exception: java.lang.RuntimeException: Unable to instantiate receiver io.branch.referral.InstallListener: java.lang.ClassNotFoundException: Didn't find class "io.branch.referral.InstallListener" on path: DexPathList[[zip file "/data/app/~~sKzUtLxdSARaU51HeDdiUQ==/<my_app_package_name>-krTvZ79pL9hO0ZsB5kiNsg==/base.apk"],nativeLibraryDirectories=[/data/app/~~sKzUtLxdSARaU51HeDdiUQ==/<my_app_package_name>-krTvZ79pL9hO0ZsB5kiNsg==/lib/arm64, /data/app/~~sKzUtLxdSARaU51HeDdiUQ==/<my_app_package_name>-krTvZ79pL9hO0ZsB5kiNsg==/base.apk!/lib/arm64-v8a, /system/lib64, /system/system_ext/lib64]]

I've also removed the previously optional receiver from manifest:

<receiver android:name="io.branch.referral.InstallListener" android:exported="true">
            <intent-filter>
                <action android:name="com.android.vending.INSTALL_REFERRER" />
            </intent-filter>
</receiver>

The crashes are reported primarily on Android 12 & Android 11 devices in crashlytics. Interestingly, all of these devices are in background state.

Any help on this would be appreciated. 😄
