当试图启动简单的服务时，BroadcastReceiver在启动时崩溃

Question

我一直在这里很长一段时间，我不知道为什么它不工作。我试图在设备启动时使用BroadcastReceiver启动服务。当设备启动时，它会崩溃并询问该活动是否已在AndroidManifest中注册。

我正在使用Genymotion模拟器，并尝试删除应用程序以及在Eclipse中清理项目。我也尝试将全名添加到android：name“com.gordon.status.service.StartBackgroundSyncService”，并且这也不起作用。

广播接收器：

public class AutostartReceiver extends BroadcastReceiver 
{ 
    @Override 
    public void onReceive(Context context, Intent intent) 
    { 
     Intent i = new Intent(context, StartBackgroundSyncService.class);  
     context.startService(i); 
    } 
} 

清单：

<service 
     android:name="service.StartBackgroundSyncService" 
     android:enabled="true" 
     android:exported="false"/> 
    <service   
     android:name="service.LinkedInBackgroundService" 
     android:enabled="true"/> 
    <receiver android:name="receiver.AutostartReceiver" 
       android:exported="false" 
       android:enabled="true"> 
     <intent-filter> 
      <action android:name="android.intent.action.QUICKBOOT_POWERON" /> <!-- For some HTC devices --> 
      <action android:name="android.intent.action.BOOT_COMPLETED"></action> 
     </intent-filter> 
    </receiver> 

服务（当装置启动时，它应该显示Hello）

public class StartBackgroundSyncService extends Service 
{ 
    @Override 
    public void onCreate() 
    { 
     super.onCreate(); 

     System.out.println("HELLO========================================================="); 
     System.out.println("=============================================================="); 
    } 

    public int startCommand(Intent intent, int flags, int startId) 
    { 
     return super.onStartCommand(intent, flags, startId); 
    } 

    @Override 
    public IBinder onBind(Intent intent) 
    { 
     return null; 
    } 
} 

logcat的：

Answer 1

某处，而不是您在此处的代码中，您正在拨打startActivity()的Intent指向您的StartBackgroundSyncService。由于StartBackgroundSyncService不是一项活动，因此失败。在这样的Intent上找到您要拨打startActivity()的地方，并将其更改为指向您应用中的实际活动。
