Android Using Multiple methods inside Asynctask -
i'm trying run background asynctask load in data.
have 2 methods load in data , i'm running them in asynctask.
when it's done loading have method called filldata fills ui data.
the problem @ moment it's filling ui whichever method finishes downloading data first.
there way run multiple methods inside 1 asynctask or need multiple asynctasks?
here's asynctask
public class posttask extends asynctask<void, string, boolean> { @override protected boolean doinbackground(void... params) { boolean result = false; loadnewsfeed(); loadresultsfeed(); publishprogress("progress"); return result; } protected void onprogressupdate(string... progress) { stringbuilder str = new stringbuilder(); (int = 1; < progress.length; i++) { str.append(progress[i] + " "); } } @override protected void onpostexecute(boolean result) { super.onpostexecute(result); log.v("bgthread", "begin fillin data"); filldata(); } } heres full code

both methods executed sequentially, because they're in 1 asynctask: first loadnewsfeed() executed, if that's finished, loadresultsfeed() executed.
so viewing code example, there's no evidence of 1 or more methods not being executed.
