java.lang.RuntimeException：无法实例化服务com.google.android.gcm.GCMBroadCastReceiver

Question

我正在开发一个android应用程序。

我正在使用GCM实施推送通知。

但是，我无法接收来自我的服务器的推送通知。错误日志如下所示。

java.lang.RuntimeException: Unable to instantiate service 
com.google.android.gcm.GCMBroadCastReceiver: java.lang.ClassNotFoundException: 
Didn't find class "com.google.android.gcm.GCMBroadCastReceiver" on path: DexPathList 

AndroidManifest.xml如下。

      </intent-filter> 
     </receiver> 

     <service android:name=".GcmIntentService" /> 

    </application> 

</manifest> 

GcmBroadcastReceiver.java位于下方。

package net.myapp; 

import android.app.Activity; 
import android.content.ComponentName; 
import android.content.Context; 
import android.content.Intent; 
import android.support.v4.content.WakefulBroadcastReceiver; 

public class GcmBroadcastReceiver extends WakefulBroadcastReceiver { 

    @Override 
    public void onReceive(Context context, Intent intent) { 

     ComponentName comp = new ComponentName(context.getPackageName(), 
       GcmIntentService.class.getName()); 

     startWakefulService(context, (intent.setComponent(comp))); 
     setResultCode(Activity.RESULT_OK); 
    } 

} 

我确认我正确导入了android-support-v4.jar和google-play-services.jar。 我尝试了Google搜索的一些解决方案，但是我还无法解决。

你能告诉我如何解决上述问题吗？

清单中您写道：

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

但是你GcmBroadcastReceiver.java是包net.myapp

变化android:name="com.google.android.gcm.GCMBroadcastReceiver"到android:name="net.myapp.GcmBroadcastReceiver"
