Error while emulating App on Samsung

Question

I apologize if this error has already appeared, but I could not solve it in my app and the previous answers did not work. I’m developing a activity show in a ListVew items registered in a specific firebase table. The idea is future, insert a filter to be able to search data within this table.

So far, the following error occurs while emulating (the app opens and runs, 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 to display the ListView):

import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;

import e.servidor.myapplication.R;

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 models of smartphones are: Samgung E7 and Samsung One.
