Why in Android Async task not working as it supposed to Do -

i have activity, splash activity, want load 2 music in , when loading finish want start welcome page, unfortunately made wrong.

even though got log made when load complete , got log when 2 music not loaded..

log

loaded 1 true loaded 2 true 1 not 2 two not 2 

code

package com.syriatel.eattel;  import android.app.activity; import android.content.intent; import android.media.audiomanager; import android.media.soundpool; import android.media.soundpool.onloadcompletelistener; import android.os.asynctask; import android.os.bundle; import android.util.log;  public class splash extends activity {       @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.splash);         new load1().execute(1);         new load2().execute(2);     }      public int soundid, soundid2;      private soundpool soundpool1, soundpool2;     boolean isload1, isload2;      class load2 extends asynctask<integer, integer, integer> {          @override         protected void onpostexecute(integer result) {             super.onpostexecute(result);             if (isload1 && isload2) {                 intent intent = new intent(splash.this, welcome.class);                 finish();                 startactivity(intent);             }else{                 log.e("2", "not two");             }         }          @override         protected integer doinbackground(integer... params) {             soundpool2 = new soundpool(10, audiomanager.stream_music, 0);             soundpool2.setonloadcompletelistener(new onloadcompletelistener() {                 @override                 public void onloadcomplete(soundpool soundpool, int sampleid,                         int status) {                     isload2 = true;                     log.e("loaded 2", "true");                 }             });             soundid2 = soundpool2.load(getapplicationcontext(), r.raw.select, 1);             return 1;         }      }      class load1 extends asynctask<integer, integer, integer> {          @override         protected void onpostexecute(integer result) {             super.onpostexecute(result);             if (isload1 && isload2) {                 intent intent = new intent(splash.this, welcome.class);                 finish();                 startactivity(intent);             }else{                 log.e("1", "not two");             }         }          @override         protected integer doinbackground(integer... params) {             soundpool1 = new soundpool(10, audiomanager.stream_music, 0);             soundpool1.setonloadcompletelistener(new onloadcompletelistener() {                 @override                 public void onloadcomplete(soundpool soundpool, int sampleid,                         int status) {                     isload1 = true;                     log.e("loaded 1", "true");                 }             });             soundid = soundpool1.load(getapplicationcontext(), r.raw.thip, 1);             return 1;         }     } } 

the problem creating separate thread within each asynctask. when call

soundid = soundpool1.load(getapplicationcontext(), r.raw.thip, 1); 

a separate thread starts loading music. however, asynctask continue in thread, complete doinbackground, go onpostexecute , when gets there neither of flags set because soundpool1.load() , soundpool2.load()` still running.

your code executing 1 expect!

to solve this, using code structure, need add code both doinbackground methods. here number 2 updated:

protected integer doinbackground(integer... params) {     soundpool2 = new soundpool(10, audiomanager.stream_music, 0);     soundpool2.setonloadcompletelistener(new onloadcompletelistener() {         @override         public void onloadcomplete(soundpool soundpool, int sampleid, int status) {             isload2 = true;             log.e("loaded 2", "true");         }     });     soundid2 = soundpool2.load(getapplicationcontext(), r.raw.select, 1);      // new code wait until load complete     while(isload2 == false) {         thread.sleep(1000); // 1 second (change feel fit)     } 

then onpostexecute when music has loaded. wise make sure initialise flags, in each asynctask:

@override protected void onpreexecute() {     isloadx = false } 

if planning lot of asynctasks, should read this , this.
