Answer 1

@coder_For_Life22 I think am late for the answer ,anyway you can do like

    @Override
    protected void onPostExecute(Void a) {

        myAsyncTask=new MyAsyncTask();
    }

in order to start a new AsyncTask after execution :)

Answer 2

You could cancel your asyncTask when you press the button and then execute it again.

Inside OnClic method:

asyncTask.cancel();
AsyncTask asyncTask = new AsyncTask();
asyncTask.execute();

Answer 3

in your MainActivity you can put so this:

LeoAsyncTask leoAsyncTaskGeneric;


public void onClick_AsyncTask(View view) {

    LeoAsyncTask leoAsyncTaskInner = new LeoAsyncTask();
    leoAsyncTaskInner.execute();

    leoAsyncTaskGeneric=leoAsyncTaskInner; 

}

/**if you create a space in memory of your AsyncTask class as a generic, then you can create an instance of that same class within the onClick method, and there the equals, so every time you press onClick you will be using a new instance of the Class AsyncTask, it will not give you problems */

Answer 4

Just create another instance and execute it.

Answer 5

Just make a new call like new asyncTask().execute(); You must create a new object to restart that task.

Answer 6

You can do it like this :

private MyAsyncTask createAsyncTask(){
    if (myAsyncTask == null){
        return myAsyncTask = new MyAsyncTask();
    }
        myAsyncTask.cancel(true);
        return myAsyncTask = new MyAsyncTask();
 }

and then you can use it :

createAsyncTask().execute();

this make a new instance of your background task everytime.
