我试图在启动时启动服务，但服务被强制关闭

广播接收器的代码如下

package com.android.locationservice;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

public class MyLocationBroadcastReceiver extends BroadcastReceiver{
    public void onReceive(Context context, Intent intent) {
        Intent startServiceIntent = new Intent();
        startServiceIntent.setAction("com.android.locationservice.LocatonTraceService");
        context.startActivity(startServiceIntent);
    }
}

清单看起来像这样

<receiver android:name="com.android.locationservice.MyLocationBroadcastReceiver">  
    <intent-filter>  
        <action android:name="android.intent.action.BOOT_COMPLETED" />  
    </intent-filter>  
</receiver> 


<service android:name=".LocationTraceService">
    <intent-filter>
        <action android:name="com.android.locationservice.LocationTraceService" />
    </intent-filter>    
</service>

</application>
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

和这样实现的服务

    package com.android.locationservice;

    import android.app.Service;
    import android.content.Intent;
    import android.os.IBinder;
    import android.widget.TextView;
    import android.widget.Toast;

    public class LocationTraceService extends Service
    {

   @Override
   public void onCreate() {
       super.onCreate();
       Toast.makeText(this, "Service created...", Toast.LENGTH_LONG).show();      
      // Log.i(tag, "Service created...");
      // new LocationActivity("service created...");

   }




@Override
   public void onStart(Intent intent, int startId) {      
       super.onStart(intent, startId);  

       Toast.makeText(this, "Service started...", Toast.LENGTH_LONG).show();
       //new LocationActivity("service started...");
   }

   @Override
   public int onStartCommand(Intent intent, int flags, int startId)
   {


       return super.onStartCommand(intent, flags, startId);
   }
   @Override
   public void onDestroy() {
       super.onDestroy();
       Toast.makeText(this, "Service destroyed...", Toast.LENGTH_LONG).show();
       //new LocationActivity("service destroyed...");
   }

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

}

请帮助我，我是android的新手，在此先感谢。

为什么你开始服务活动，而不是服务？正确的：

public class MyLocationBroadcastReceiver extends BroadcastReceiver{
    public void onReceive(Context context, Intent intent) {
        startService(new Intent(context, LocatonTraceService.class));
    }
}

我认为您在 AndroidManifest.xml 中缺少 GPS 权限

<uses-permission android:name="android.permission.ACCESS_GPS"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
