Android startResolutionForResult返回错误（应用程序崩溃），GoogleAppClient connect

很长一段时间以来，我一直在想如何解决这个问题，但我找不到任何关于问题所在的好信息

代码源于：

因此，首先我构建GoogleAppClient对象，然后onStart（）尝试连接它。 连接失败，我最终进入了“onConnectionFailed（）”

这里我已经打印了结果，这是我得到的：“需要签名”

由于该错误具有解决方案，因此将调用“result.startResolutionForResult（this，REQUEST_RESOLVE_error）”

这就是程序突然崩溃的地方

任何帮助都会被感激的，我对android开发还很陌生，所以对我放松点

在

onCreate

方法中，尝试：

• 删除重复的行

  super.onCreate（savedInstanceState）

• 删除

  .addScope（Plus.SCOPE\u Plus\u LOGIN）

  或

  设置范围（“Plus\u LOGIN”）

如果这没有帮助，请尝试从SDK示例导入并运行伟大的示例项目：

<android-sdk-folder>/extras/google/google_play_services/

您能从
adb logcat
打印stacktrace吗？我收到了同样的问题。在onConnectionFailed（）方法中获取ConnectionResult=null.PS：您不需要在onConnectionSuspended方法中再次调用connect（），因为如果成功，它将自动尝试重新连接并调用onConnected（）。
