locking - How to lock a file in Actionscript? -

-

using actionscript 3.0, how can lock file? i'd write highscores file , place game on server, don't want things go wrong when 2 players submit highscore @ same time. openasync() method of filestream suffice this?

thanks shaunhusain:

when placing project on webserver, swf-file sent client machine , processed there, each user of flash app/game have own high scores list on own machine. in order handle scores being submitted you'll need php, believe mysql handle concurrency issues you. other server side languages , databases work equally well, 2 know , documented , free.

android - getbluetoothservice() called with no bluetoothmanagercallback -

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
