I just modified my onPostExecute(...) method:
protected void onPostExecute(String result) {
Log.i("LOGGER", "Done...");
pDialog.dismiss();
if(result=="success"){
Toast.makeText(ctx, "complete",
Toast.LENGTH_LONG).show();
Intent i=new Intent(ctx,SillyActivity.class);
startActivity(i);
}else{
Toast.makeText(ctx, "fail",
Toast.LENGTH_LONG).show();
}
super.onPostExecute(result);
}
ctx is my context
I noticed that I can't call the startActivity(Intent i) method within
the AsyncTask, how else would I start an activity from here?
