Cannot see events in firebase analytics debug view

Question

I'm trying to run a sample app with firebase analytics. I followed the firebase analytics guides to log a test event but I cannot see any events in the debug view. I log a test event on my main activity as below:

public class MainActivity extends AppCompatActivity
{
    private FirebaseAnalytics mFirebaseAnalytics;

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mFirebaseAnalytics = FirebaseAnalytics.getInstance(this);

        Bundle bundle = new Bundle();
        bundle.putString("test_parameter", "test_value");
        mFirebaseAnalytics.logEvent("test_event", bundle);
    }
}

And I use the following command to see my events in the debug view:

adb shell setprop debug.firebase.analytics.app com.example.firebaseanalyticssample

And I see the logs with the following commands:

adb shell setprop log.tag.FA VERBOSE
adb shell setprop log.tag.FA-SVC VERBOSE
adb logcat -v time -s FA FA-SVC

I think maybe the problem is the null pointer exception appeared in the logs (the last line):

I searched a lot and just found this link regarding the exception above that says it must be an error from another application. but whenever my activity is resumed this exception occurs. I don't think that in my case this exception is caused by another apps.

I checked my sample app a lot of times so that every configuration would be exactly as the guides say. Have you any idea what can be the problem?

Answer 1

After performing Enabling debug mode make sure that date&time in your debug device or emulator and in your pc is correct.

Answer 2

To enable sending of DebugView data on a connected Android test device for a configured Firebase Analytics app, execute the following command:

adb shell setprop debug.firebase.analytics.app <package_name>

This behavior persists until you explicitly disable it by executing the following command:

adb shell setprop debug.firebase.analytics.app .none.

iOS test device setup is as easy as Android, just use there Xcode command line arguments correspondingly:

–FIRDebugEnabled and

–FIRDebugDisabled
