改变

 <service android:name="com.pushbots.push.GCMIntentService" />
        <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>

与

<service android:name="com.pushbots.push.GCMIntentService" >
        <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
 </service>

请发布您的 GCMBroadcastReceiver 类
