Question

我是GCM的新手，当我在清单文件中声明权限时遇到问题。当我运行app时，它给我IllegalStateException应用程序没有定义权限com.example.technopits.dcn.permission.C2D_MESSAGE 所以请帮助我。

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.technopits.dcn" >
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

    <!-- GCM requires a Google account. -->
    <uses-permission android:name="android.permission.GET_ACCOUNTS" />

    <!-- Keeps the processor from sleeping when a message is received. -->
    <uses-permission android:name="android.permission.WAKE_LOCK" />
    <!-- Creates a custom permission so only this app can receive its messages. -->
    <permission
        android:name="com.example.technopits.dcn.GCM.permission.C2D_MESSAGE"
        android:protectionLevel="signature" />

    <uses-permission android:name="com.example.technopits.dcn.GCM.permission.C2D_MESSAGE" />
    <!-- This app has permission to register and receive data message. -->
    <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />

    <!-- Network State Permissions to detect Internet status -->
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

    <!-- Permission to vibrate -->
    <uses-permission android:name="android.permission.VIBRATE" />
    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/MyMaterialTheme.Base" >
        <receiver
            android:name="com.google.android.gcm.GCMBroadcastReceiver"
            android:permission="com.google.android.c2dm.permission.SEND" >
            <intent-filter>

                <!-- Receives the actual messages. -->
                <action android:name="com.google.android.c2dm.intent.RECEIVE" />
                <!-- Receives the registration id. -->
                <action android:name="com.google.android.c2dm.intent.REGISTRATION" />

                <category android:name="com.example.technopits.dcn" />
            </intent-filter>
        </receiver>



        <activity android:name=".activity.Test"></activity>
        <activity android:name=".activity.MultiLogin"></activity>
        <activity android:name=".GCM.Main"></activity>

    </application>

</manifest>

我在logcat中得到权限错误

您有权限

com.example.technopits.dcn.GCM.permission.C2D_MESSAGE

要求

com.example.technopits.dcn.permission.C2D_MESSAG

删除权限的.GCM部分，使其与请求的权限格式匹配。
