我已经看到了很多关于该主题的问题和答案，但我无法解决我的问题。

我正在尝试将 AdView 添加到我的活动 xml 文件中。这是我的 listactivity.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" 
android:id="@+id/mainLayout">  


<com.google.ads.AdView
    android:id="@+id/adView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    ads:adSize="BANNER"
    ads:adUnitId="my great unit ID"
    ads:loadAdOnCreate="true" />

<EditText
    android:id="@+id/etSearch"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:hint="@string/hladanyRetazecHint"
    android:singleLine="true" />

<ScrollView
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <TableLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/tlForItems"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:stretchColumns="*" >
    </TableLayout>
</ScrollView>

在活动课上我有这样的东西：

AdView adView = (AdView) findViewById(R.id.adView);
             AdRequest r=new AdRequest();
             r.addTestDevice(AdRequest.TEST_EMULATOR);
             adView.loadAd(r);

我总是遇到异常，我的应用程序停止工作。这是堆栈跟踪：

adRequest.addTestDevice(AdRequest.TEST_EMULATOR);

我也尝试清理项目并再次构建它，但它没有帮助，但最后我自己解决了它。

对我有用的是：我只是删除所有外部库并再次加载它。然后我重新启动 Eclipse，然后它运行。=)
