you haven't added crash logs error may here:
public void onclick(view view) { startactivity(new intent("com.example.gmapsapp.mainactivity")); } i change this:
public void onclick(view view) { intent intent = new intent(this, mainactivity.class); startactivity(intent); } or forgot declare activity google maps in manifest
