我刚刚将AdMob添加到了我的应用中。当我调试或安装发布版本的应用程序（HTC m7）时，一切似乎都运行良好。问题出现在CHUWI VX2设备上（esky82_tb_cn_kk，Android 4.4）。这很奇怪，因为在这个设备上我的应用程序在调试模式下工作，但在发布版本中不起作用。我尝试转向葫芦，但它对我没有帮助。
有人对此有所了解吗？
我的清单
我的onCreate方法中的指令：
mAdView = (AdView) findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder().build();
mAdView.setAdListener(new AdListener() {
@Override
public void onAdClosed() {
super.onAdClosed();
mAdView.setVisibility(View.GONE);
}
@Override
public void onAdOpened() {
super.onAdOpened();
mAdView.startAnimation(fade_in);
mAdView.setVisibility(View.VISIBLE);
}
@Override
public void onAdFailedToLoad(int errorCode) {
super.onAdFailedToLoad(errorCode);
mAdView.setVisibility(View.GONE);
}
@Override
public void onAdLoaded() {
super.onAdLoaded();
mAdView.startAnimation(fade_in);
mAdView.setVisibility(View.VISIBLE);
}
@Override
public void onAdLeftApplication() {
super.onAdLeftApplication();
mAdView.setVisibility(View.GONE);
}
});
mAdView.loadAd(adRequest);

mAdView.setAdListener(new AdListener() {
答案 0 :(得分：2)
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
试试这个
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
然后让其余的去吧
答案 1 :(得分：0)
我解决了我的问题。此问题未与AdView连接。这是项目的问题。我犯了小错误。我没有这条线
<?xml version="1.0" encoding="utf-8"?>
在xml布局文件的开头。我不知道它是如何运作的。
然后我的apk开始工作而没有progourd但是当我启用此功能时崩溃。所以我找到this solution
