AdMob应用不断崩溃

Question

我的代码： 爪哇：

import android.os.Bundle;
import android.app.Activity;
import android.util.AttributeSet;
import android.view.Gravity;
import android.view.Menu;
import android.widget.LinearLayout;

import com.google.ads.AdRequest;
import com.google.ads.AdSize;
import com.google.ads.AdView;

public class MainActivity extends Activity
{

private AdView adView;

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    adView = (AdView) findViewById(R.id.adView);

    AdRequest request = new AdRequest();
    request.setTesting(true);
    adView.loadAd(request);

}

@Override
protected void onDestroy()
{
    super.onDestroy();
    if(adView!=null) adView.destroy();
}

@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;
}

}

的xml：

<LinearLayout xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/linearlayout"
    android:orientation="vertical">

<com.google.ads.AdView
        android:id="@+id/adView"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        ads:adUnitId="MY_UNIT_ID"
        ads:adSize="BANNER"
        ads:testDevices = "MY_TEST_DEVICE"
        android:layout_gravity="bottom"/>
</LinearLayout>

清单：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="...."
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="10"
    android:targetSdkVersion="16" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="com....MainActivity"
        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.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

它只是在我的测试设备上崩溃：setContentView（R.layout.activity_main）; 该应用程序未发布在Play商店中，因为我想先测试它。 所以错误应该在xml中。我希望你能帮助我。

编辑2：我通过阅读本文来了解它：Android Studio - Error inflating class com.google.ads.AdView并在终端中执行gradlew clean并单击Build - ＆gt;重建项目。谢谢你的帮助！

Answer 1

我通过阅读本文来了解它：Android Studio - Error inflating class com.google.ads.AdView并在终端中执行“gradlew clean”并单击Build - ＆gt;重建项目。谢谢你的帮助！

Answer 2

您需要在项目中导入googleadmob.jar ...从admob网站下载并从中提取googleAdmobAdsSdk.jar ..将其复制到项目的libs文件夹中

现在右键单击项目 - ＆gt;构建路径 - ＆gt; java Build Path-＆gt;库 检查jar是否已导入，如果没有，请单击添加jar并从libs文件夹中添加

现在检查订单和导出选项卡，确保该jar上有勾号

点击确定

可能会有所帮助..

Answer 3

你需要在LinearLayout

的开头声明xmlns：android

您还需要将admob代码导入库
