无法实例化GcmBroadcastReceiver

Question

根据Google手册https://developer.android.com/google/gcm/client.html#app,我尝试使用GCM服务创建测试应用

但是当我收到消息时 - 我有这个错误:

无法实例化接收机com.example.testpushnotification.GcmBroadcastReceiver:抛出java.lang.ClassNotFoundException:没有找到路径类 "com.example.testpushnotification.GcmBroadcastReceiver":DexPathList [zip文件"/data/app/com.example. testpushnotification-2.apk"],nativeLibraryDirectories = [/数据/ APP-LIB/com.example.testpushnotification-2,/销售商/ lib下,/系统/ lib中]]

我正在寻找所有相同的问题,但他们没有解决方案或解决方案没有帮助或他们被弃用.

我的清单:

<?xml version="1.0" encoding="utf-8"?>

    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <meta-data android:name="com.google.android.gms.version"
           android:value="@integer/google_play_services_version"/> 

    <activity

        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <receiver
        android:name=".GcmBroadcastReceiver"
        android:permission="com.google.android.c2dm.permission.SEND">
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE"/>
            <action android:name="com.google.android.c2dm.intent.REGISTRATION" />
            <category android:name="com.example.testpushnotification"/>
        </intent-filter>
    </receiver>
    <service android:name=".GcmIntentService"/>
</application>

以及com.example.testpushnotification包中GcmBroadcastReceiver的源代码:

public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        // Explicitly specify that GcmIntentService will handle the intent.
        ComponentName comp = new ComponentName(context.getPackageName(),
                GcmIntentService.class.getName());
        // Start the service, keeping the device awake while it is launching.
        startWakefulService(context, (intent.setComponent(comp)));
        setResultCode(Activity.RESULT_OK);
    }

为什么Dex路径包含不同于我的包？

请问,如何解决？

固定已更改<receiver android:name=".GcmBroadcastReceiver" .. </receiver>

<receiver android:name="com.google.android.gcm.GCMBroadcastReceiver" .. </receiver>(案例判断)

试试这个:

转到项目/属性/ Java构建路径/订单和导出 - 确保在Android Dependencies和支持库前面有一个检查,如果您使用它.标记所有复选框.单击应用并清理项目.

像这样添加:

   <receiver
        android:name="com.google.android.gcm.GCMBroadcastReceiver"
        android:permission="com.google.android.c2dm.permission.SEND" >
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <action android:name="com.google.android.c2dm.intent.REGISTRATION" />

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

它应该是:com.google.android.gcm.GCMBroadcastReceiver而不是.GCMBroadcastReceiver

这对我有用.希望这有帮助.
