android - GCM 错误 - googleCloudMessaging.register

Question

我遇到了 android 应用程序所说的问题。 “The application xxxx Sorry stopped”与推送通知一起工作，当执行调试器时发生在它通过时:

方法一

InstanceID InstanceId = InstanceID.getInstance (context);

 token = instanceID.getToken (key_id.toString ()

GoogleCloudMessaging.INSTANCE_ID_SCOPE); getToken error,

方法二

都是同一个错误

 if (googleCloudMessaging == null) {
googleCloudMessaging = GoogleCloudMessaging.getInstance(context);
                    }
                    token = googleCloudMessaging.register(key_id);

注意生成了token但是应用关闭了，报错:

"The method 'java.io.File android.support.v4.content.ContextCompat.getNoBackupFilesDir (android.content.Context)' was expected to be of type virtual but was found to be Instead of direct type (declaration of 'java.lang .reflect.ArtMethod 'appears in /system/framework/core-libart.jar)"

我正在使用 android studio，因为cdvCompileSdkVersion = android-22cdvBuildToolsVersion = 22.0.1

错误:

可能是什么问题？
