DebugView no devices available

Question

I'm doing some tests on a small app to understand how firebase-analytics works. This is the code for the MainActivity:

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(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);
}

To see if my app send data to Firebase I tryed to use DebugView but it says that there isn't any devices available, i also used the command

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

but nothing changed.
If i use these 3 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 can see that my app is sending some data to firebase, like in this picture

What can i do to enable DebugView and see what my app send to firebase in real time?

Please ensure that the following steps have been followed:

Step 1: Your app is properly configured in the Firebase console to support the Analytics features.

Step 2:

A) If you are simply working with single build variant, the following command is enough:

adb shell setprop debug.firebase.analytics.app [your_app_package_name]

B) But if you are working with multiple build variants with different application IDs which are not the same as the app package name, be sure to execute the following command:

adb shell setprop debug.firebase.analytics.app [your_application_id]

Here, application ID is the app ID of your build variant found in the corresponding gradle file. For example, lets say you have x.gradle and y.gradle for two build variants x and y, and you also have the general build.gradle file. To debug the build variant x with application ID com.abc.x, the command will be:

adb shell setprop debug.firebase.analytics.app com.abc.x

Similarly, to debug the build variant y with application ID com.abc.y, the command will be:

adb shell setprop debug.firebase.analytics.app com.abc.y

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

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

Answer 2

I had the same symptoms as you did. In my case the problem was simply because I forgot to turn on WiFi, so events couldn't be propagated to cloud but were appearing in logcat.

Answer 3

You can see your list of devices -> adb devices

and then -> adb shell setprop debug.firebase.analytics.app package_name

after that, in Android Studio, run by Debug
