这是我的 MainActivity.java 文件
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.main, menu);
return true;
}
}
这是我的清单

我也在我的手机上运行它而不是在模拟器上,我已经安装了谷歌播放服务,所以我不知道我在哪里犯了错误。提前谢谢。
