any assistance appreciated, incredibly stuck on this. in advance , if need clarification, let me know.

java.lang.runtimeexception: query has outstanding network connection. have wait until it's done.

it sounds parsequery doesn't support multiple concurrent find requests.setconversationslist() reuses same query instance execute 3 background requests. since aren't changing query each of requests, can handle in single findcallback.

note: breaking method sub-methods make code easier read , debug.

edit:

every handler starts on list argument , calls get() on each object, different argument.

for (int = 0; < users.size(); i++) {     //...     users.get(i).get("xxxx")     //... } 

i expect able call get() each of different arguments within single call back. once collect information, can update ui.

for (parseuser user : users) {     //...     user.get("aaa")     user.get("bbb")     user.get("ccc")     //... } 

you can use for-each loop instead of calling users.get(i) every time.
