AsyncTask onPostExecute()가 호출되지 않는 경우가 있음

데이터를 요청하고 UI를 업데이트하는 AsynTask가 있지만 작업을 호출 할 때 가끔 onPostExecute()가 호출되지 않습니다. AsyncTask onPostExecute()가 호출되지 않는 경우가 있음

나는 실행 흐름을 확인하기 위해 로그를 추가 onPostExecute는 마지막 로그 호출되지 때 doInBacground()의 반환하기 전에 하나입니다 ->
는 앱이 사람이 비슷한 경험이 정지?

이 Asynctaskexecutor으로 실행 안드로이드 API 버전이 14 이상인 경우

낮은 버전의 Android에서는 모든 AsyncTask가 단일 배경 th에서 실행 되었기 때문에 독서. 따라서 다른 작업이 완료 될 때까지 새로운 작업이 대기 중일 수 있습니다.

Android의 하위 버전 (실제로 HONEYCOMB 이전 버전)에서는 실행 프로그램에서 AsyncTask를 실행할 수 없습니다.

if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) 
    task.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR); 
else 
    task.execute();

HONEYCOMB execute() 메서드를 실행하기 전에 AsynkTask를 병렬로 실행하십시오.
