根据AdMob tutorial，我尝试在我的片段中显示测试广告。
我的片段XML中包含以下代码：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.example.myapp.DetailFragment">
<TextView
android:id="@+id/txvTitle"
style="@style/TextAppearance.AppCompat.Headline"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/title"/>
<com.google.android.gms.ads.AdView
android:id="@+id/adView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
ads:adSize="BANNER"
ads:adUnitId="@string/banner_ad_unit_id">
</com.google.android.gms.ads.AdView>
</LinearLayout>
banner_ad_unit_id 取自教程（作为测试ID）：
<string name="banner_ad_unit_id">ca-app-pub-3940256099942544/6300978111</string>
我的片段类中有以下代码：
public void onViewCreated(View view, Bundle savedInstanceState)
{
super.onViewCreated(view, savedInstanceState);
AdView mAdView = (AdView) view.findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder()
.addTestDevice(MY_TEST_ID_BY_ADS_LOG)
.build();
mAdView.loadAd(adRequest);
}
根据AdMob教程，测试广告应该可见。
我在日志中遇到的是一个奇怪的编解码器错误然后错误0 和错误3 ：

我还应该设置什么？
