Hi @hoanganh-gu This is most likely caused because you are either writing to or querying on the UI thread. If the UI thread is blocked for more than 5 seconds it will cause an ANR. You can detect if you are doing this by enabling RealmConfiguration.allowQueriesOnUiThread(false) and RealmConfiguration.allowWritesOnUiThread(false). Realm will then crash if you try this. Instead you should switch to our findAllAsync or excuteTransactionAsync methods.

Got that point, we are switching to async methods. Thanks @cmelchior
