的Android GPS V2教程問題 - 谷歌地圖

Question

我一直在學習本教程[http://www.androidhive.info/2013/08/android-working-with-google-maps-v2/]

它的GPS地圖位置應用程序可以獲取您的位置或附近的位置。我和其他許多人都對此進行了測試，並且應用程序崩潰時似乎出現錯誤。 我已更改SHA1指紋和Google API密鑰。 代碼中沒有錯誤，我導入了Google Play商店。

有沒有人有這方面的任何想法，我看了網站上的評論和用戶分配有同樣的問題。 這裏是logcat的：

Answer 1

你logcat中明確表示：

Caused by: java.lang.IllegalStateException: A required meta-data tag in your app's AndroidManifest.xml does not exist. 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" /> 
03-26 03:43:53.845: E/AndroidRuntime(15048): at com.google.android.gms.common.GooglePlayServicesUtil.t(Unknown Source) 
03-26 03:43:53.845: E/AndroidRuntime(15048): at com.google.android.gms.common.GooglePlayServicesUtil.isGooglePlayServicesAv 

添加谷歌Play服務版本，您的應用程序的清單

編輯應用程序的AndroidManifest.xml文件，並在元素中添加 聲明。這嵌入了該應用程序編譯的Google Play服務版本 。

你只需要添加<meta-data>下<application>代碼到你的AndroidManifest.xml

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

這是因爲谷歌最新的播放服務，需要一個版本的名稱，這是使用<meta-data .. />提到內部AndroidManifest.xml

建立你的manifest.xml像：

....<application> 
    .............. 
    <meta-data 
    android:name="com.google.android.maps.v2.API_KEY" 
    android:value="APIKEY" /> 

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

    </application>
