Is this proper use of AsyncTask ?

AsyncTask is generic type and you should use generics with them is code more faster, more type-safe.

I have no use in performing any UI

So you rather can use Handler or classical Runnable interface and you can work only with worker threads basically.

Note: Generally, using of generics types makes code faster, most type-safe. Also next advantage is strong type checking at compile source code, restrictions of explicit conversions etc.
