I've got a problem that I am really confused, doing so much debugging, but still cannot solve the problem.
id_kecamatan = categoriesList.get(position).getId(); value changed when the second spinner generated with second Asynctask, which is not suppose to be happen, but if I'm not execute the code which is found in public void onItemSelected the value of ID position not changed, which is suppose to be happen, and if I'm not put this code I can't populate the second spinner because the second spinner is based on first spinner value. This problem causing multiple looping onSelectedItem. please help. thanks.
if I put this code down below, categoriesList.get(position).getId(); is changed.
if (cekspin != cekstatusspin1){
spinnerFood2.setEnabled(true);
id_kecamatan = categoriesList.get(position).getId();
Log.d("MASUK KE 2: ", "> " + id_kecamatan);
cekstatusspin1 = cekspin;
//run the second asynctask for second spinner
runMultipleAsyncTask2();
}

Oh, i find a solution, the problem is on onItemSelected i just add this and problem solved!
Spinner spinner = (Spinner) parent;
if(spinner.getId() == R.id.spinner1)
{
//do this
}
else if(spinner.getId() == R.id.spinner2)
{
//do this
}
