Question

这是我的主要活动代码

public class MainActivity extends Activity {
    public static class AdFragment extends Fragment {   }

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

        AdView mAdView = (AdView) this.findViewById(R.id.adView);
        AdRequest adRequest = new AdRequest.Builder().build();
        mAdView.loadAd(adRequest);


        final MediaPlayer sButtonClick = MediaPlayer.create(this, R.raw.turkey_gobbling);


        Button mButton = (Button) findViewById(R.id.call);
        mButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

            }
        });
    }


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

    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}


Every time I run my app it crashes and I can't find a solution, and my code looks fine.
Here is my `MainActivity.xml` and my Manifest file. I've searched hours for this and now I find errors in `ActivityThread.java`, `Method.java` and `Activity.java`

您需要创建onActivityCreated方法。这是您构建和加载AdRequest的地方。引用AdView，然后构建并加载AdRequest。不在OnCreate。例如：

  /**
     * A placeholder fragment containing a simple view. This fragment
     * would include your content.
     */
    public static class PlaceholderFragment extends Fragment {

        public PlaceholderFragment() {
        }

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                                 Bundle savedInstanceState) {
            View rootView = inflater.inflate(R.layout.fragment_my, container, false);
            return rootView;
        }
    }

    /**
     * This class makes the ad request and loads the ad.
     */
    public static class AdFragment extends Fragment {

        private AdView mAdView;

        public AdFragment() {
        }

        @Override
        public void onActivityCreated(Bundle bundle) {
            super.onActivityCreated(bundle);

            // Gets the ad view defined in layout/ad_fragment.xml with ad unit ID set in
            // values/strings.xml.
            mAdView = (AdView) getView().findViewById(R.id.adView);

            // Create an ad request. Check logcat output for the hashed device ID to
            // get test ads on a physical device. e.g.
            // "Use AdRequest.Builder.addTestDevice("ABCDEF012345") to get test ads on this device."
            AdRequest adRequest = new AdRequest.Builder()
                    .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
                    .build();

            // Start loading the ad in the background.
            mAdView.loadAd(adRequest);
        }

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                                 Bundle savedInstanceState) {
            return inflater.inflate(R.layout.fragment_ad, container, false);
        }

        /** Called when leaving the activity */
        @Override
        public void onPause() {
            if (mAdView != null) {
                mAdView.pause();
            }
            super.onPause();
        }

        /** Called when returning to the activity */
        @Override
        public void onResume() {
            super.onResume();
            if (mAdView != null) {
                mAdView.resume();
            }
        }

        /** Called before the activity is destroyed */
        @Override
        public void onDestroy() {
            if (mAdView != null) {
                mAdView.destroy();
            }
            super.onDestroy();
        }

    }
}

请参阅Reference Tutorial - 他们建议使用片段来封装AdView。

我的应用程序在模拟器中启动时关闭。怎么了？
