Error emulating App on Samsung

I apologize if this error has already appeared, but I was unable to resolve it in my app and the previous responses did not work. I am developing a activity that shows in a ListVew the items registered in a specific table of the firebase. The idea is to insert a filter in the future to search data within this table.

So far, the following error occurs when emulating (the app opens and executes but does not show my ListView ):

  

D / AbsListView: Get MotionRecognitionManager   E / MotionRecognitionManager: mSContextService = null                               motionService = com.samsung.android.motion.IMotionRecognitionService$Stub$Proxy@3a9482a5   D / SecWifiDisplayUtil: Metadata value: none

My Bakery Activity (where it should display ListView ):

public class Padaria extends AppCompatActivity {

    Firebase objetoRef;
    ListView minhaListPadaria;
    ArrayList<String> minhaLVpadaria = new ArrayList<>();


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

        Firebase.setAndroidContext( this );

        minhaListPadaria = (ListView) findViewById( R.id.LV_padaria );
        objetoRef = new Firebase( "https://console.firebase.google.com/u/0/project/projeto-eb1cf/database/projeto-eb1cf/data" );

        Firebase novaRef = objetoRef.child( "padaria" );

        final ArrayAdapter<String> adaptador = new ArrayAdapter<String>( this, android.R.layout.simple_list_item_1, minhaLVpadaria );
        minhaListPadaria.setAdapter( adaptador );

        novaRef.addChildEventListener( new ChildEventListener() {
            @Override
            public void onChildAdded(com.firebase.client.DataSnapshot dataSnapshot, String s) {
                String message = dataSnapshot.getValue( String.class );
                minhaLVpadaria.add( message );
                adaptador.notifyDataSetChanged();

            }

            @Override
            public void onChildChanged(com.firebase.client.DataSnapshot dataSnapshot, String s) {

            }

            @Override
            public void onChildRemoved(com.firebase.client.DataSnapshot dataSnapshot) {

            }

            @Override
            public void onChildMoved(com.firebase.client.DataSnapshot dataSnapshot, String s) {

            }

            @Override
            public void onCancelled(FirebaseError firebaseError) {

            }
        });
    }
}

Can you help me? The smartphone models are: Samgung E7 and Samsung One.
