Can't Stop/restart Asynctask

Please help. I can restart the AsyncTask. App crashes every time, when second call to updatePoi(). Here is my code: I'm checking status of task and set cancel(true). public void u

Solution 1:

An AsyncTask instance can only be called once. To make a second call, you need to create a new instance.

Solution 2:

You can't restart a task. Each task object may only be executed once:

The task can be executed only once (an exception will be thrown if a second execution is attempted.)

So create a new object each time you execute it, don't use the same object.

Solution 3:

try

returnnull;

final code

@OverrideprotectedVoid doInBackground(Void... voids) {
    Application app = (Application)getApplication();
    Log.d(TAG, "exits count = " + app.getExits().size());

    GeoPoint pointToNavigate = null;

    for (Exit exit : app.getExits()) {

        for (Poi poi : exit.getPoi()) {
            if (isCancelled()){
                returnnull;
            }
            //some code here
        }
    }

    //small code herereturnnull;
