java.lang.RuntimeException：無法實例化服務com.google.android.gcm.GCMBroadCastReceiver

Question

我正在開發一個android應用程序。

我正在使用GCM實施推送通知。

但是，我無法接收來自我的服務器的推送通知。錯誤日誌如下所示。

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。

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

     <receiver

      </intent-filter> 
     </receiver> 

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

    </application> 

</manifest> 

GcmBroadcastReceiver.java位於下方。

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); 
    } 

} 

我確認我正確導入了android-support-v4.jar和google-play-services.jar。 我嘗試了Google搜索的一些解決方案，但是我還無法解決。

你能告訴我如何解決上述問題嗎？

清單中您寫道：

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

但是你GcmBroadcastReceiver.java是包net.myapp

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