How to set a fixed time if AsyncTask is not finished

Issue

I have an asynctask and I'm looking to do a wait if the async is taking too long, I'm downloading some data of the database , but I don't want to have the user looping around the progressdialog, I want to set a fixed time, lets say I'm downloading a file but is taking forever, so I tell the user, "hey, check your internet connection and try again" I'm looking to do this with a timer, but I'm kinda stuck, this is where I do my asynctask

private class DownloadFilesTask extends AsyncTask<Void, Void, Void> {
             String s;
             public DownloadFilesTask(String s){
                 this.s = s;
             }

             @Override
             protected Void doInBackground(Void... voids) {
                 DownloadMethod(s);
                 return null;
             }
         }

so let's say I want to execute that downloadmethod for a fixed time, 10 or 20 seconds, if the file is not downloaded at that time I return a message to the user saying that he needs to check for hes internet.

Solution

You can use handler to run after a definite amount time and maintain a boolean flag which you can update in postExecute function of async task.

In your activity/fragment class:

new Handler().postDelayed(new Runnable(){
          public void run(){
                   //Check whether the flag has been updated or not
             },1000)
