java - Admob 广告不会加载。错误2，之前还可以，突然就停止了

Question

这是我尝试将横幅广告加载到其中的整个类(createAd() 方法完成工作)

public class HomeActivity extends Activity {

    private HomeView homeView;
    private ImageView playButton;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);

//        playButton = (ImageView)findViewById(R.id.playButton);
//        playButton.setImageBitmap(BitmapFactory.decodeResource(getResources(),
//                R.drawable.play));
//        setListener();
        setContentView(R.layout.home_main);
        createAd();

    }

    private void setListener (){
        playButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                playButton.setImageBitmap(BitmapFactory.decodeResource(getResources(),
                        R.drawable.play2));
                playGame();
            }
        });
    }

    private void createAd(){
        setContentView(R.layout.home_main);
        AdView adView = (AdView)findViewById(R.id.bottomAd);
        AdRequest.Builder adRequestBuilder = new AdRequest.Builder();
        adRequestBuilder.addTestDevice("FEACCF89D31180ABDD853C9C3DD2E871");
//                .addTestDevice("1744314CD0C7B0619F94D44CE2E5093E");

        adView.loadAd(adRequestBuilder.build());
    }

    public void playGame() {
        SharedPreferences savedData = getApplicationContext()
                .getSharedPreferences("lastScore", Context.MODE_PRIVATE);
        int score = savedData.getInt("lastScore", Context.MODE_PRIVATE);
        Intent intent = new Intent(HomeActivity.this, GamePlay.class);
        intent.putExtra("lastScore", score);
        startActivity(intent);
        finish();
    }

    @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;
    }

    @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();
        if (id == R.id.action_settings) {
            return true;
        }
        return super.onOptionsItemSelected(item);
    }
}

这里是home_main的xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/homeRelative"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".HomeActivity">

    <com.google.android.gms.ads.AdView
        xmlns:ads="http://schemas.android.com/apk/res-auto"
        android:id="@+id/bottomAd"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        ads:adSize="SMART_BANNER"
        ads:adUnitId="@string/admob_banner_id">
    </com.google.android.gms.ads.AdView>

</RelativeLayout>

这是我最近一次运行后的日志

如果有人能帮助我，那就太好了。我真的不知道问题出在哪里。也许我错过了一些非常简单的东西，只需要另一双眼睛。感谢您的帮助，谢谢。
