I am still learning the android apps development and after I started making a very simple app with google maps api v2 (not using it yet) when i run it on my Sony Xperia SL it says “Unfortunately myapp stopped”. The red msg’s in the LogCat are “Can’t open file for reading” (twice).

MainMenu.java

public class MainMenu extends Activity {

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

    Button bntStart = (Button) findViewById(R.id.buttonStart);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(1, menu);
    return true;
}
}

MainActivity.java

public class MainActivity extends Activity {

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

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
}

}

    Most likely you’re facing a problem because of this line in MainMenu:

    getMenuInflater().inflate(1, menu);

    inflate() expects a resource ID pointing to an XML menu file, and a Menu object. However, 1 is almost certainly not a valid ID, resulting in an exception. Try passing in an ID to a Menu XML file.
