Prosta aplikacja map na Androida (google api v2). Nie działa. Błąd
Staram się programować łatwą aplikację mapową na Androida, ale jedynym wynikiem są błędy. Próbowałem go zaprogramować tak, jak powinno, ale nadal nie działa.
główna aktywność
package com.example.guidebook;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
public class GuidebookActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.guidebook);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.guidebook, menu);
return true;
}
}
