error: Can't create handler inside thread that has not called Looper.prepare()

Tread를 사용하다 보면 다음과 같은 오류가 발생함.

 

Can't create handler inside thread that has not called Looper.prepare()

 

이때 아래 코드를 사용하면 됨.

 

참조해야될 라이브러리

import android.os.Handler;
import android.os.Looper;

 

Handler mHandler = new Handler(Looper.getMainLooper()); mHandler.postDelayed(new Runnable() { @Override public void run() { // code } }, 0);

Timer에서의 사용 예

TimerTask timerTask = new TimerTask() { @Override public void run() { Handler mHandler = new Handler(Looper.getMainLooper()); mHandler.postDelayed(new Runnable() { @Override public void run() { double latitude = ""; double longitude = ""; gps = new Gps(); latitude = gps.getLatitude(); longitude = gps.getLongitude(); SaveLocation(phoneNumber, rLatitude, rLongitude); } }, 0); } }; Timer timer = new Timer(); timer.schedule(timerTask, 5, 10000);
