[READ] Step 1: Are you in the right place?

Issues filed here should be about bugs in the code in this repository.
If you have a general question, need help debugging, or fall into some
other category use one of these other channels:

• For general technical questions, post a question on StackOverflow
  with the firebase tag.
• For general Firebase discussion, use the firebase-talk
  google group.
• For help troubleshooting your application that does not fall under one
  of the above categories, reach out to the personalized
  Firebase support channel.

[REQUIRED] Step 2: Describe your environment

• Android Studio version: 3.3 alpha
• Firebase Component: Database
• Component version: 16.0.2

[REQUIRED] Step 3: Describe the problem

Steps to reproduce:

I have a simple app with only these dependencies:

dependencies {
    implementation 'androidx.appcompat:appcompat:1.0.0-alpha1'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.2'

    implementation 'com.google.firebase:firebase-database:16.0.2'
}

With 16.0.1 I can see this:

$ ./gradlew clean assembleDebug
$ cat app/build/intermediates/merged_manifests/debug/processDebugManifest/merged/AndroidManifest.xml  | grep permission
    <uses-permission android:name="android.permission.INTERNET" />

However with 16.0.2 the same operation shows me no permissions in the merged manifest. If I run my app, it crashes pretty much immediately for lack of INTERNET permission.

Relevant Code:

public class MainActivity extends AppCompatActivity {

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

        FirebaseApp.initializeApp(this, new FirebaseOptions.Builder()
            .setApplicationId("12345")
            .setDatabaseUrl("https://mockproject-1234.firebaseio.com")
            .build());

        DatabaseReference ref = FirebaseDatabase.getInstance().getReference();
    }
}
