# FAQ & Troubleshooting

<summary>Historical Android 12 PendingIntent crash (older WorkManager dependencies)</summary>

Some older dependency combinations produced the following Android 12 error. Diagnose the resolved WorkManager version rather than assuming every app using AGP 7.2.0 is affected:

```
2022-06-14 11:30:19.954 21270-21290/tv.fw.example.discovery E/AndroidRuntime: FATAL EXCEPTION: pool-3-thread-1
    Process: tv.fw.example.discovery, PID: 21270
    java.lang.IllegalArgumentException: tv.fw.example.discovery: Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent.
    Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable, e.g. if it needs to be used with inline replies or bubbles.

```

The historical workaround used WorkManager 2.7.1, as discussed in [the original report](https://stackoverflow.com/a/69152986/2359762). This is not a recommendation to pin a current app to that old version:

```
    // Required to avoid crash on Android 12 API 31
    // https://stackoverflow.com/a/69152986/2359762
    implementation("androidx.work:work-runtime-ktx:2.7.1")
```

Inspect your resolved dependency tree and choose a WorkManager version compatible with your application. Keep this workaround limited to the matching historical crash.

## Analytics callbacks missing in minified builds

SDK **6.35.1** fixes a known issue where R8 could remove analytics callbacks. If you encounter this issue on an older SDK, upgrade to a version containing the fix. The standard SDK artifact includes the required callback keep rules.

Ensure the listener is still registered while events are expected and follows the [analytics registration lifecycle](/firework-for-developers/android-sdk/integration-guide/analytics.md#firework-analytics).
