java - Android GPS V2 教程问题-Google map

Question

我一直在使用本教程 [http://www.androidhive.info/2013/08/android-working-with-google-maps-v2/]

它的 GPS map 位置应用程序可以获取您的位置或附近的位置。我和其他许多人对此进行了测试，似乎出现了错误，因为应用程序崩溃了。我已经更改了 SHA1 指纹和 Google API key 。代码没有错误，我已经导入了google play store。

有人对此有任何想法吗？我查看了网站上的评论，很多用户都遇到了同样的问题。这是 LogCat:

Answer 1

你的 logcat 明确表示:

 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

将 Google Play 服务版本添加到您应用的 list 中

Edit your application's AndroidManifest.xml file, and add the following declaration within the element. This embeds the version of Google Play services that the app was compiled with.

您只需添加 <meta-data>下<application>标记到您的 AndroidManifest.xml

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

这是因为最新的Google Play服务需要版本名称，可以使用<meta-data .. />来提及。里面AndroidManifest.xml

构建您的ma​​nifest.xml，如下所示:

....<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>
