Android 如何在AlarmManager运行的Serivce类上正确运行异步任务

我正在运行一个

AlarmManager

，它使用以下命令每隔

x秒触发一次
Serivce
：

Intent intent = new Intent(AndroidGPSTrackingActivity.this,
        AppService.class);
PendingIntent sender =
        PendingIntent.getService(AndroidGPSTrackingActivity.this,
                0, intent, 0);

AlarmManager am = (AlarmManager)
        getSystemService(ALARM_SERVICE);
am.cancel(sender);

服务类声明为：
清单中的

AppService.java:

public class AppService extends Service {
    GPSTracker gps;

    @Override
    public IBinder onBind(Intent intent) {
        // TODO: Return the communication channel to the service.
        throw new UnsupportedOperationException("Not yet implemented");
    }

    @Override
    public void onCreate() {
        // TODO Auto-generated method stub
        //Toast.makeText(getApplicationContext(), "Service Created", 1).show();
        super.onCreate();

公共类SendLocation扩展了AsyncTask{//第18行
私人双纬度、经度；
私有字符串用户名、密码；
GlobalClass Global=新的GlobalClass（）；
受保护的Void doInBackground（对象…参数）{
纬度=（双）参数[0]；
经度=（双）参数[1]；
HttpClient HttpClient=新的DefaultHttpClient（）；
HttpPost HttpPost=新的HttpPost（Global.getHostServer（））；//第28行
试一试{
List nameValuePairs=新的ArrayList（2）；
添加（新的BasicNameValuePair（“strLat”，双精度）
.toString（纬度））；
添加（新的BasicNameValuePair（“strLong”，双精度）
.toString（经度））；
添加（新的BasicNameValuePair（“userName”，Global.getUserName（））；
添加（新的BasicNameValuePair（“密码”，Global.getPassword（））；
setEntity（新的UrlEncodedFormEntity（nameValuePairs））；
HttpResponse response=httpclient.execute（httppost）；
字符串responsest=EntityUtils.toString（response.getEntity（））；
Log.d（“响应”，responsest）；
}捕获（客户端协议例外e）{
//TODO自动生成的捕捉块
}捕获（IOE异常）{
//TODO自动生成的捕捉块
}
返回null；
}
}

它工作了一段时间，然后突然我得到两个错误，一个在第18行，一个在第28行，然后最终。。。一股力量关闭了。知道我为什么要接近这支部队吗

更新：
当android在试图释放内存时自动关闭应用程序时，这是一个明确的强制关闭。如何解决此问题

我在您的代码中看到的唯一奇怪的事情与您的AsyncTask的
参数有关。您的声明如下所示：

public class SendLocation extends AsyncTask<Object, Void, Void> 

public class SendLocation extends AsyncTask<Double, Void, Void> 

您应该更改异步任务的定义，如下所示：

public class SendLocation extends AsyncTask<Object, Void, Void> 

public class SendLocation extends AsyncTask<Double, Void, Void> 

公共类SendLocation扩展了异步任务
事实证明，在
