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:
无法实例化接收器 com.example.testpushnotification.GcmBroadcastReceiver: java.lang.ClassNotFoundException:没找到类 " com.example.testpushnotification.GcmBroadcastReceiver"在路径上: DexPathList [[zip文件 " /data/app/com.example.testpushnotification-2.apk"], nativeLibraryDirectories = [/数据/ APP-LIB / com.example.testpushnotification-2, / vendor / lib,/ system / lib]]
我一直在寻找所有相同的问题,但他们没有任何解决方案或解决方案没有帮助,或者他们已被弃用。
我的清单:

</application>
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路径包含的包不同于我的?
请问,如何解决?
已修复已更改<receiver
android:name=".GcmBroadcastReceiver"
..
</receiver>
到<receiver
android:name="com.google.android.gcm.GCMBroadcastReceiver"
..
</receiver>

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>
应该是: com.google.android.gcm.GCMBroadcastReceiver 而不是 .GCMBroadcastReceiver
这对我有用。希望这有帮助。

我关注了developer.android教程:/google/gcm/client.html
我的问题是我有&#34; Android Dependencies&#34;在属性 - > Java构建路径 - >订单和导出下打勾。
适当的库列表:
希望这有助于那里的人!
此代码是正确的
<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.infostretch.iSOSAndroid" />
</intent-filter>
</receiver>

我遇到了同样的问题。但解决了它,让我分享我的解决方案步骤..
我的主要问题是GcmBroadcastReceiver类,它扩展了WakefulBroadcastReceiver并且需要v4库。我出于某些原因添加了多个库,其中一个包含v4,我只是从该库中删除了v4。将v7作为库添加到我的应用程序中,然后清理并运行...然后它的工作原理。抱歉我的英语不好,我只是分享我的经验来帮助。

Mi Fix是使用Manifest Editor Wizard来更改服务和接收者的名称。结果是:
<application
android:allowBackup="true"
android:icon="@drawable/journey_icon"
android:logo="@drawable/journey_icon"
android:permission="android.permission.INTERNET"
android:theme="@style/AppTheme" >
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
<receiver
android:name=".GCMBroadcastReceiver"
android:permission="com.google.android.c2dm.permission.SEND" >
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<category android:name="com.example.JourneyApp" />
</intent-filter>
</receiver>
<service android:name=".GCMIntentService" />
已更改为
<application
android:allowBackup="true"
android:icon="@drawable/journey_icon"
android:logo="@drawable/journey_icon"
android:permission="android.permission.INTERNET"
android:theme="@style/AppTheme" >
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
<receiver
android:name="journeyAux.GCMBroadcastReceiver"
android:permission="com.google.android.c2dm.permission.SEND" >
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<category android:name="com.example.JourneyApp" />
</intent-filter>
</receiver>
<service android:name="journeyAux.GCMIntentService" />
