TreKing,

Well... The following code does not produce any Eclipse errors but
does produce the "Sorry! App has stopped unexpectedly..." when I try
to run it on the emulator, AVD.
private class getNextBook_T extends AsyncTask<Void, Void, Integer> {
private ProgressDialog pd1;
protected Integer doInBackground(Void... arg0 ) {
pd1 = ProgressDialog.show(App01.this, "", "Downloading
next
book...", true);
return getNextBook();
}
protected void onPostExecute(Integer result) {
pd1.dismiss();
setDisplay("");
}
}
The DDMS LogCat display shows:
03-28 15:42:32.132: ERROR/AndroidRuntime(227): Caused by:
java.lang.RuntimeException: Can't create handler inside thread that
has not called Looper.prepare()
Thanks, John
I did get it to work. Your post prompted me to try it a different way.
I just didn't get it at first.
Thanks, John Brown
