Android storage performance

Question

I am actually developing an Android application with a data warehouse, and I continue like this:

Activity → Business Services → Repo (with Spring REST fw). Using this, I am forced to allow the activity to complete the storage job before closing it (thread processing, progress dialog ...).

Is this a bad coding method for using android service to store data?

At the same time, users can continue to move around and have the impression that they are working with a very flexible application. This is a good decision?

thank

There is no need to keep your activities in the foreground, waiting for the completion of background logic.

: .

class MyActivity extends Activity {

     void calledWhenActivityNeedsToBeClosed() {

          // start a thread to do background work
          new Thread() {
                public void run() {
                     perform long running logic here
                }
          }.start();

          // and clos the activity without waiting for the thread to complete
          this.finish();
     }
}
