除非删除SEND权限,否则不会收到GCM消息

Question

为了正确实现GCM,com.google.android.c2dm.SEND应根据官方文档为接收者指定权限:

接收方应该要求com.google.android.c2dm.SEND权限,以便只有GCM框架可以向其发送消息.

但是,当我添加该权限时,收到消息时会收到此错误.

W/GTalkService(25224):[DataMsgMgr]广播意图回调:result = CANCELED forIntent {act = com.google.android.c2dm.intent.RECEIVE cat = [com.XXX.XXX](有附加内容)}

然后是这个错误:

W/ActivityManager(283):权限拒绝:从com.google.android广播Intent {act = com.google.android.c2dm.intent.RECEIVE cat = [com.XXX.XXX] flg = 0x10(有额外内容)}.由于接收方com.XXX.XXX/com.XXX.XXX.GcmBroadcastReceiver,syncadapters.contacts需要com.google.android.c2dm.SEND.

如果我仅删除该权限,而不更改任何其他内容,则接收器正常工作,我可以处理该消息.

这是AndroidManifest.xml中的接收器定义

<receiver
        android:name="com.XXX.XXXX.GcmBroadcastReceiver"
        android:permission="com.google.android.c2dm.SEND" >
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />

            <category android:name="com.XXX.XXX" />
        </intent-filter>
    </receiver>

我在测试期间使用调试证书,以防可能相关.

Answer 1

尝试com.google.android.c2dm.permission.SEND代替com.google.android.c2dm.SEND,例如:

<receiver
  android:name="GCMBroadcastReceiverCompat"
  android:permission="com.google.android.c2dm.permission.SEND">
  <intent-filter>
    <action android:name="com.google.android.c2dm.intent.RECEIVE"/>
    <category android:name="com.commonsware.android.gcm.client"/>
  </intent-filter>
</receiver>
