I have an Android application, which uploads data into web service using async tasks(P,Q,R) currently starting fired in button click. I have three tables(A,B,C) of data. Currently I upload Table A data in doInBackground in first async task(P), I call second async task(Q) in onPostExecute of first async task(P).In onPostExecute, I update my local tables with returned data and give some UI messages as well. while that functionality is existing, now I want to upload data in a fixed time interval(every 30 minutes) even though the application is closed. when the device is booting up/installing app/updating app, this process should be started.While uploading data, if the user opens the application, upload button should be disabled.I don't necessarily need a long running task that runs forever. 1.Do I need to use services instead async tasks? and give me advice on this.

Your Receiver class
import java.util.Timer;
import java.util.TimerTask;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class yourReceiver extends BroadcastReceiver {
@Override
public void onReceive(final Context context, Intent intent) {
int delay = 5000; // delay for 5 sec.5000
int period = 60000; // repeat every 1min.60000
Timer timer = new Timer();
timer.scheduleAtFixedRate(new TimerTask() {
public void run() {
Intent serviceIntent = new Intent(context,UploadService.class);
context.startService(serviceIntent);
}
}, delay, period);
}
}
Your Service Class
import android.app.Service;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.IBinder;
import android.widget.Toast;
public class UploadService extends Service {
MediaPlayer myPlayer;
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public void onCreate() {
Toast.makeText(this, "Service Created", Toast.LENGTH_LONG).show();
myPlayer = MediaPlayer.create(this, R.raw.sun);
myPlayer.setLooping(false); // Set looping
}
@Override
public void onStart(Intent intent, int startid) {
Toast.makeText(this, "Service Started", Toast.LENGTH_LONG).show();
serviceThread = new ServiceThread();
serviceThread.start();
}
@Override
public void onDestroy() {
Toast.makeText(this, "Service Stopped", Toast.LENGTH_LONG).show();
myPlayer.stop();
}
private class ServiceThread extends Thread {
@Override
public void run() {
synchronized(UploadService.class){
if(uploadStatus) {
uploadStatus = false;
uploadData();
uploadStatus =true;
}
}
}
}
}

To Upload Data do as follow
I think you are pretty new to android, Rather than Asynctasks i think you should move to volley or retrofit which is very easy and very fast when compared to Asynctask
Do I need to use services instead async tasks
Since you need to upload data every 30 mins i suggest you move your code to a service within which you will upload data. Also since a service is used it will work when the app is closed also, as it runs in the background
