FirebaseAnalytics.getAppInstanceId() for android devices does not work

Describe the bug When using your own example, calling FirebaseAnalytics.getAppInstanceId(): Its returning an string like: ‘com.google.android.gms.tasks.zzu@575g1e6’

After checking FirebaseAnalytics class at android folder, I’ve found the problem:

public void getAppInstanceId(PluginCall call) {
    try {
      if (mFirebaseAnalytics == null) {
        call.error(MISSING_REF_MSSG);
        return;
      }
      String instanceId = mFirebaseAnalytics.getAppInstanceId().toString();  // this line isn't returning the expected value

If you read the documentation of FirebaseAnalytics, you will see that getAppInstanceId will return an Task<String> (what explain the answer I am receiving)

How to solve it Replace your method for something like:

     @PluginMethod
     public void getAppInstanceId(final PluginCall call) {
           try {
                  if (mFirebaseAnalytics == null) {
                       call.error(MISSING_REF_MSSG);
                       return;
           }
      Task<String> task = this.mFirebaseAnalytics.getAppInstanceId();
      task.addOnSuccessListener(new OnSuccessListener<String>() {
        @Override
        public void onSuccess(String string) {
          JSObject result = new JSObject();
          result.put("instanceId", string);
          call.success(result);
        }
      });
      
    //task.addOnFailureListener(...)
    } catch (Exception ex) {
      call.error(ex.getLocalizedMessage());
    }
  }

Its just required to implement the addOnFailureListener to finish it.

Sorry for the late reply. Version 0.3.2 works perfectly! Thanks for resolving this issue 👍

Is there any news about resolving this issue? It’s a bit frustrating since this seems to need only a small correction.

Thanks for bringing this up again @Franjoo , I’ll see if I can get on it this week.
