AsyncTasker

Pooja's AsyncTask Challenge Self Implemented Async Task for Pooja Srivs Challenge

API design

This is a sample project api design is similar to that of asyncTask,

abstract class AsyncTasker<Params, Progress, Result> {

    abstract fun doInBackground(vararg many: Params): Result
    abstract fun onPostExecute(data: Result)
    abstract fun onPreExecute()
    abstract fun onProgressUpdate(progress: Progress)
    
    /** Extra function that is called when every task complete **/
    abstract fun onCompleted(isInterrupted: Boolean)

    /** controller function **/
    fun execute(vararg many: Params) {
      ... doing stuff
    }

    /** function that interrupt underlying worker thread for immediate cancel of task **/
    fun cancel() {
       ... doing stuff
    }
}

Behind the Back uses HandlerThread as worker thread and handler to perform the task.

Sample

1. click fab to perform async task
2. long click fab to perform cancel async task

TODO

• test cases
• flag to check background task is active
