【问题描述】：
我正在运行 Admob 6.0.1 并尝试在表面视图的顶部添加广告，我可以说下面的代码适用于 Android 3.2（真实设备），也适用于模拟器中的 android 4 设备但是，当我尝试在 pre api13 上进行测试时，例如 2.3.3 或更低版本的广告不显示。现在这是奇怪的部分，如果我将surfaceview（在xml中）的可见性更改为不可见，广告将显示！！！这是怎么回事？？这只是模拟器有问题还是我真的有问题？
我已尝试使代码尽可能简单以重现错误。我添加了一个按钮，只是为了显示表面视图确实允许更新其他视图，而不是 Admob 视图...
package com.google.example.ads.fundamentals;

/** The view to show the ad. */

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.layout);
adView = (AdView) findViewById(R.id.adView);
}
/** Called before the activity is destroyed. */
@Override

// Destroy the AdView.
if (adView != null) {

@Override

_thread.setRunning(true);
_thread.start();
}
@Override
public void surfaceDestroyed(SurfaceHolder holder) {
// simply copied from sample application LunarLander:
// we have to tell thread to shut down & wait for it to finish, or
// else
// it might touch the Surface after we return and explode
boolean retry = true;
_thread.setRunning(false);
while (retry) {
try {
_thread.join();
retry = false;
} catch (InterruptedException e) {
// we will try it again and again...
}

}

synchronized (_surfaceHolder) {
_panel.onDraw(c);
}
} finally {
// do this in a finally so that if an exception is thrown
// during the above, we don't leave the Surface in an
// inconsistent state
if (c != null) {
_surfaceHolder.unlockCanvasAndPost(c);
}
}
}
}
}
和 XML：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
android:layout_width="match_parent" android:layout_height="match_parent">
<com.google.example.ads.fundamentals.Panel
android:id="@+id/mainPanel" android:layout_width="match_parent"
android:layout_height="match_parent" android:visibility="invisible" />
<com.google.ads.AdView android:id="@+id/adView"
android:layout_width="match_parent" android:layout_height="wrap_content"
android:layout_gravity="top" ads:adSize="BANNER" ads:adUnitId="xxxxxxxxx"
ads:loadAdOnCreate="true" ads:testDevices="TEST_EMULATOR" />
<Button android:id="@+id/mybutton" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:layout_below="@id/adView"
android:text="hello" />
</RelativeLayout>
还有清单：
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.google.example.ads.fundamentals"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="3" android:targetSdkVersion="15" />
<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".BannerSample"
android:screenOrientation="portrait"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="com.google.ads.AdActivity"
android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"/>
</application>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.INTERNET"/>
</manifest>
任何想法或帮助都会非常棒，我曾尝试在 Google 网上论坛上发布 admob，但我认为它迷失了。
