java - 膨胀类 com.google.ads.AdView 时出错

Question

您好，我是 android dev 和 admob 的新手。我正在尝试制作一个简单的测试应用程序，底部有一个按钮、几个页面和 admob。在我尝试实现 admob 之前一切正常。这是我的代码:

HelloAndroid.java:

package com.manny.HelloAndroid;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageView;

public class HelloAndroid extends Activity {
    /** Called when the activity is first created. */
    private static final int ACTIVITY_CREATE = 0;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);


        setContentView(R.layout.main);
        ImageView image = (ImageView) findViewById(R.id.test_image);
        //image.setScaleType(ImageView.ScaleType.FIT_XY);

    }
    public void onClick(View v){
        Intent i = new Intent(this, HelloPage2.class);
        startActivityForResult(i, ACTIVITY_CREATE);
    }
}

main.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="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <ImageView 
        android:id="@+id/test_image"
        android:src="@drawable/bak_vert_480x800"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:scaleType="fitXY"
        />

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="@string/hello" />
    <ImageButton 
        android:id="@+id/test_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/btn_arrow"
        android:layout_marginLeft="100dp"
        android:layout_marginTop="200dp"
        android:onClick="onClick"
        />
     <com.google.ads.AdView android:id="@+id/adView"
                         android:layout_width="wrap_content"
                         android:layout_height="wrap_content"
                         ads:adUnitId="b14be806e9ddf1f"
                         ads:adSize="BANNER"
                         ads:testDevices="TEST_EMULATOR, TEST_DEVICE_ID"
                         ads:loadAdOnCreate="true"/>

</RelativeLayout>

你好android list :

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

    <uses-sdk android:minSdkVersion="7" 
        android:targetSdkVersion="13"/>

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" 
        android:theme="@android:style/Theme.NoTitleBar.Fullscreen">
        <activity
            android:name=".HelloAndroid"
            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=".HelloPage2">
        </activity>
    <activity android:name="com.google.ads.AdActivity"
                    android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|s    mallestScreenSize"/>

我正在使用 GoogleAdMobAdsSdkAndroid-6.0.0。同样，我对此很陌生，我尝试过在多个站点上使用示例，但是当应用程序访问包含 admob 的页面时，该应用程序继续崩溃。如果有人可以帮助我，将不胜感激。谢谢你。如果需要更多代码，请告诉我。

Answer 1

您最近是否将您的 Android 工具更新到 r17 或更高版本？如果是这样，您需要在项目中创建一个 libs/文件夹，并将 SDK 物理放入项目中。或者，在 Java 构建路径中，您必须订购和导出 SDK jar。

否则，当您的 apk 被编译时，jar 不会被包含在内，而当您在运行时运行 AdMob 代码时，一切都会崩溃。

注意:这适用于您的项目引用的任何库。
