java - How to solve ConcurrentModificationException in GoogleMaps in Android -

i have written code displaying multiple markers in googlemaps in android. code follows.

list<overlay> markerslist; private myitemizedoverlay funplaces; runnable r = new runnable() { public void run() { if (markerslist != null) { mapcontroller mc = mapview.getcontroller(); mc.setzoom(15); (int i=0; < markerslist.size(); i++) { funplaces = (myitemizedoverlay) markerslist.get(i); geopoint pt = funplaces.getcenterpt(); mc.setcenter(pt); mapview.postinvalidate(); } } } }; thread t=new thread(r,"classname"); t.start();

when i'm running above code working fine giving concurrentmodificationexception. how prepare problem? thought appreciated.

if that's you're getting error, you're modifying arraylist while iteration in progress. can't tell code you've provided whether that's due actual concurrency, or performing modifications on arraylist during iteration, that's going reason.

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
