I have a progress dialog that I use for a part in my program where I do a time intensive operation in the background but when the dialog gets displayed the UI or spinner icon freezes/slow/hesitates making the program appear as if it froze. In my onPostExecute
of my AsyncTask
I dismiss the dialog.
Why would this happen since I am doing all the work in the background?
here is my code
pDialog = ProgressDialog.show(FullGame.this,"Starting New Game","Please Wait...", true);
new StartNewGame().execute();
private class StartNewGame extends AsyncTask<Void,Void,Boolean>{
@Override
protected Boolean doInBackground(Void... params) {
try{
ContentValues values = new ContentValues();
Cursor c = getContentResolver().query(Games.PART1_URI,new String[] {Games.PART1_NUM},
Games.PART1_GAME_ID+"="+gameID+" AND "+Games.PART1_FRAME_NUM+"="+10,null,null);
c.moveToFirst();
String num = c.getString(0);
int part1 =0;
if(num.equals("-")){
part1=0;
}else{
part1=Integer.parseInt(num);
}
c = getContentResolver().query(Games.PART2_URI,new String[] {Games.PART2_NUM},
Games.PART2_GAME_ID+"="+gameID+" AND "+Games.PART2_FRAME_NUM+"="+10,null,null);
c.moveToFirst();
int part2 = 0;
if(num.equals("-")){
part2=0;
}else{
part2=Integer.parseInt(num);
}
c = getContentResolver().query(Games.PART3_URI,new String[] {Games.PART3_NUM},
Games.PART3_GAME_ID+"="+gameID,null,null);
c.moveToFirst();
int part3 = 0;
if(num.equals("-")){
part3=0;
}else{

}

UPDATE: running through the code in debug mode last night it seems to start to do it in the for loop but still all of this is done in a separate thread and I am only inserting values into my database
UPDATE 2
if I comment out the for loop the progress dialog gets displayed for less than a second so even though I am doing everything in an AsyncTask
the inserts must still run in the UI thread
This probably happens because your background thread consumes 100% of device CPU. When CPU is busy processing one thread, UI thread won't be updated and therefore you see it as frozen
Try to detect what's the most aggressive operation by removing parts of code from your doInBackground and running the app again. Also try to see how it performs when device is not plugged via USB - this some times provides weird results
Figured it out, I had a runaway method going on the UI thread that i did not notice
