请给我你最好的帮助。

提前致谢

【问题讨论】：

是的。对我没有帮助

【参考方案1】：

您的设备没有播放商店来处理市场协议"market://details?id=com.google.android.gms"您需要在该设备上安装播放服务或在具有播放服务的另一台设备上运行您的代码

编辑

这是您检查播放服务的方式

int supported = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());
if(supported == 0) // success! do something
    Log.v("play services ", " supported"); 
else
    Log.v("play services ", " not supported"); 

【讨论】：

跑在 emluator.needs google play service update.on 手机根本不运行

如果它支持谷歌服务，这只是脸皮。我的问题不是最新的 emlutaor 并且根本没有在手机中运行

【参考方案2】：

你有没有在 manifest.xml 中定义它，像这样

<activity
    android:name=".ActivityName"
    android:label="@string/label" >
</activity>
