Android，java.lang.IllegalStateException

Question

我收到一个提及添加元数据的例外，但即使添加后我仍然收到相同的异常。你能帮我解释一下我怎么能拒绝它吗？

01-08 20:22:05.380: E/AndroidRuntime(2335): Caused by: java.lang.IllegalStateException: 
The meta-data tag in your app's AndroidManifest.xml does not have the right value.      
Expected 4030500 but found 0.  You must have the following declaration within the 
<application> element:     <meta-data android:name="com.google.android.gms.version"   
android:value="@integer/google_play_services_version" />

在这里，你可以看到我的AndroidManifest

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.googlemapv2"
android:versionCode="1"

            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
 <meta-data

            <meta-data android:name="com.google.android.gms.version" 
        android:value="@integer/google_play_services_version" />
</application>

 </manifest>

试着把它改为。

<meta-data
    android:name="com.google.android.gms.version"
    android:value="4030500" />

如果这不起作用，请看一下。也许你有一个旧版本的GMS，或者没有正确链接到你的项目。
