我有一个Android应用程序，它由活动，接收器和服务组成。 安装后只启动一次活动以设置用户名和密码，然后启动服务。电话启动后，接收器会调用该服务。电话进入睡眠状态后，服务会进入休眠状态，我需要全部工作时间 。我已将调用网站放在一个帖子中。这是服务

public URL myURL;
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public void onCreate() {
super.onCreate();
Toast.makeText(this,"Service created ...",Toast.LENGTH_LONG).show();
final SQLiteDatabase db=openOrCreateDatabase("TruckMe", MODE_PRIVATE, null);
String idvozaca=new String();
db.execSQL("create table if not exists vozac (id INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL, idvozaca VARCHAR(15));");
Cursor d=db.rawQuery("select idvozaca from vozac", null);
if(d.getCount() > 0)
{
d.moveToLast();
idvozaca=d.getString(d.getColumnIndex("idvozaca"));
mojsadrzaj=idvozaca;
}
final Time t=new Time();
final Handler handler = new Handler();
final Runnable runnable = new Runnable() {
public void run() {
if(indikator != 0)
{
try {

URLConnection myURLConnection = myURL.openConnection();
myURLConnection.connect();
BufferedReader in = new BufferedReader(new InputStreamReader(myURLConnection.getInputStream()));
String inputLine;
while ((inputLine = in.readLine()) != null)
System.out.println(inputLine);
in.close();

indikator=1;
handler.postDelayed(this, 180000);

Criteria criteria = new Criteria();
criteria.setAccuracy(Criteria.ACCURACY_FINE);

final LocationManager m=(LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
String locationprovider =m.getBestProvider(criteria,true);

String mydate = java.text.DateFormat.getDateTimeInstance().format(Calendar.getInstance().getTime());
mydate=mydate.replaceAll("\\s","");

Log.e("Poruka", url);
// TODO Auto-generated method stub
}
};
runnable.run();
m.requestLocationUpdates(locationprovider, 180000, 0, l);
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
return START_STICKY;
}
@Override
public void onStart(Intent intent, int startId) {
//Toast.makeText(this, "Service started onstart...",Toast.LENGTH_LONG).show();
}
@Override

db.execSQL("drop table vozac;");
}
}
由于我不想让我的服务永远休眠，我应该将m.requestLocationUpdates（locationprovider，180000,0，l）减少到60000，把所有内容从调用gps从oncreate到onstartcommant，或者我应该做什么。< / p>
