Question

我正在研究GCM。我的应用程序甚至没有启动并变得混乱。跟随错误

        </intent-filter>
    </receiver>
    <service android:name=".GCMIntentService" />
    <service android:name=".DialogService" />
</application>

收到以下错误

 java.lang.RuntimeException: Unable to start activity ComponentInfo{com.ama.gcmdemo/com.ama.gcmdemo.MainActivityActivity}: java.lang.IllegalStateException: Application does not define permission com.ama.gcmdemo.permission.C2D_MESSAGE

主要活动在com.ama.gcmdemo包下直接进行。

请说明故障在哪里

Answer 1

在清单文件中提供此权限

  <permission
    android:name="<package-name>.permission.C2D_MESSAGE"
    android:protectionLevel="signature" />

<uses-permission android:name="<package-name>.permission.C2D_MESSAGE" />

<!-- This app has permission to register and receive data message. -->
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />

代替package-name，提供您的包名称

Answer 2

试试这个..

只需更改接收器内的以下行，

android:name="com.google.android.gcm.GCMBroadcastReceiver"

要，

android:name="com.ama.gcmdemo.GCMBroadcastReceiver"

并确保您的包中有GCMBroadcastReceiver.java。 Bcs，你应该在你的包中有接收器来接收GCM消息。

Answer 3

您需要使用GCM包名称而不是应用程序包名称定义您的接收者，如下所示：

     <receiver
    android:name="com.google.android.gcm.GCMBroadcastReceiver">

不会

<receiver android:name="com.google.android.gcm.GCMBroadcastReceiver"

GCM错误（权限错误）
