在 firebase 分析调试视图中看不到事件

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):

05-25 09:25:53.056 V/FA      (21533): Processing queued up service tasks: 2

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

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

Try this

  private FirebaseAnalytics mFirebaseAnalytics;

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

    mFirebaseAnalytics = FirebaseAnalytics.getInstance(getApplicationContext());

    mFirebaseAnalytics.setAnalyticsCollectionEnabled(true);

    mFirebaseAnalytics.setMinimumSessionDuration(10000);

    mFirebaseAnalytics.setSessionTimeoutDuration(300);


    Bundle bundle = new Bundle();
    bundle.putString(FirebaseAnalytics.Param.ITEM_ID,"ID");
    bundle.putString(FirebaseAnalytics.Param.ITEM_NAME,"NAME");
    bundle.putString(FirebaseAnalytics.Param.CONTENT_TYPE,"image");

   mFirebaseAnalytics.logEvent(FirebaseAnalytics.Event.SELECT_CONTENT, bundle);
   }

You can enable verbose logging with a series of adb 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 changed my development android phone and it got worked. it got worked with samsung SM-P601 and Huawei ِY560-U02 but it just kept throwing the exception below for android mobile phone samsung SM-J120F:

05-25 09:25:53.666 E/FA-SVC  ( 5655): Task exception on worker thread: java.lang.NullPointerException: Attempt to invoke virtual method 'long java.lang.Long.longValue()' on a null object reference: vgq.s(:com.google.android.gms:2650)

I checked google play services version in these three mobile phones and it was the same in all of them. I don't know what causes SM-J120F not to work.

执行启用调试模式后，请确保调试设备或仿真器和PC中的日期和时间正确无误。

Answer 5

Didn't work for me. But from logs, I've found that you need to add flavor name too. So, I had a flavor named "internal" and had to write com.package.name.internal in that adb command above.

Answer 6

In my case, I was using illegal characters in the name field.

Logcat gave the hint why this was happening to me: I was using a blank space in the name, which is illegal. You can only use [A-Za-z0-9_] .

Here my error message:

E/FA: Name must consist of letters, digits or _ (underscores).
