Answer 1

You can use async Task in android. Here's some important highlights

create an async task

private class MyTask extends AsyncTask<Void, Void, Void> { ... }

it will have 4 methods that you can override.

onPreExecute()
doInBackground(Params...)
onProgressUpdate(Progress...)
onPostExecute(Result)

basically, you just need to put the method that you wanna trigger in the onPostExecute method.

protected void onPostExecute(Long result) {
    //add your method here
}

for more details please refer to android documentation on AsyncTask.
