android - 除非删除 SEND 权限，否则不会收到 GCM 消息

Question

为了正确实现 GCM，应根据 the official docs 为接收方指定 com.google.android.c2dm.SEND 权限:

The receiver should require the com.google.android.c2dm.SEND permission, so that only the GCM Framework can send a message to it.

但是，当我添加该权限时，收到消息时出现此错误。

W/GTalkService(25224): [DataMsgMgr] broadcast intent callback: result=CANCELLED forIntent { act=com.google.android.c2dm.intent.RECEIVE cat=[com.XXX.XXX] (has extras) }

随后出现此错误:

W/ActivityManager(283): Permission Denial: broadcasting Intent { act=com.google.android.c2dm.intent.RECEIVE cat=[com.XXX.XXX] flg=0x10 (has extras) } from com.google.android.syncadapters.contacts requires com.google.android.c2dm.SEND due to receiver com.XXX.XXX/com.XXX.XXX.GcmBroadcastReceiver

如果我只删除该权限，而不更改任何其他内容，接收方将正常工作，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，以防相关。

Answer 1

尝试使用 com.google.android.c2dm.permission.SEND 而不是 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>
