Caused by java.lang.IllegalArgumentException: There is no GcmTaskService component registered within this package. Have you extended GcmTaskService correctly?

Answer 1

1.) 您是否在清单文件中声明了您的服务，如下所示：

<service android:name="MyTaskService"
          android:permission="com.google.android.gms.permission.BIND_NETWORK_TASK_SERVICE"
          android:exported="true">
          <intent-filter>
              <action android:name="com.google.android.gms.gcm.ACTION_TASK_READY"/>
          </intent-filter>
 </service>

确保您已包含权限BIND_NETWORK_TASK_SERVICE

2) 确保您的服务正在扩展 GcmTaskService 并且正在实现onRunTask。
