Firebase Analytics - NPE in CrashReport

I've just migrated to Firebase Analytics 9.0.0 and when tried to launch the app on emulator api10/x86, then the following exception is thrown by the services. Any ideas how to work around that?

The code is nothing more than activity with:
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
FirebaseCrash.log("onCreate: " + getClass().getSimpleName());
}

Unfortunately, using Firebase on devices or emulators without Play Services isn't a supported use case. Crash Reporting will fail to initialize, and you will see a message to that effect in logcat when the app launches. However, if you are also seeing a crash when calling a method after failed init, that seems like a problem we should correct.
It sounds like you are doing the best thing you can by suppressing the exception, but I'd rather not make you go through that, so I'll pass it on as feedback to the team.

Just small correction on what Doug mentioned. Firebase Crash Reporting is not supported on non-play devices. Firebase Analytics in particular and some of the other Firebase product do support non-play devices.

I am using Firebase and I got this Exception when create the firebase object [duplicate]

Take a look at Android App is crashing when connecting to Firebase. This appears to be a bug in the firebase android client. To avoid this Error use firebase android client version 2.5.0 instead of 2.5.1 which I assume you are using now.

java.lang.NoClassDefFoundError when calling DolbyAudioProcessing.getDolbyAudioProcessing

I have integrated Dolby_audio_plugin_api_v1.1.1.0 into my Android app and am seeing this stack trace in a handful of cases:

Following the examples on the Dolby dev site, this is the call that tries to initialize the DolbyAudioProcessing instance:
mDolbyAudioProcessing = DolbyAudioProcessing.getDolbyAudioProcessing(this, PROFILE.MUSIC, this);
According to Crashlytics, all instances were on a Samsung GT-S5360B or GT-S5360L, running Android 2.3.6.
Very minor thing, given how infrequent it is, but it makes me curious. Has anyone else seen this before?

So this turned out to be a because the AppActivityLifecycleCallbacks is an ICS API Level interface. I should have been doing SDK_LEVEL check before calling DolbyAudioProcessing.getDolbyAudioProcessing(). – mmcmahon

App crashes when trying to extend SherlockActivity in android studio

After importing the actionbarsherlock module, my app crashes on any activity that extends the SherlockActivity. I am not sure if I had imported it incorrectly or something needs to be adjusted but I have followed a guide that was previously posted here on stackoverflow. If i extend Activity and not sherlockActivity there will be no crash.

You need to make sure that the dependency scope is set to "compile". In some cases it seem to be set to "provided" which will cause a NoClassDefFoundError.

Probably your application is for Android 3.0 or higher and you are running it on Android 2.x

Your Project should target Android version 3.0 or above to use getActionBar() function.

To have the ActionBar in older versions of Android, you can have a look at ActionBarSherlock (http://actionbarsherlock.com/). It uses the ActionBar when it is available, and falls back on a custom implementation if it isn't available.
