hi, i understand that Kindle doesn’t have an external mic, and i am testing using a headset with a mic. SimpleAudioRecorder is not working well as it’s not really recording any sound, and the playback is infinite. but at least it is not crash.
but the following code:
local music\_channel = audio.findFreeChannel()
dataFileName = "hello.aif"
local filePath = system.pathForFile( dataFileName, system.DocumentsDirectory )
r = media.newRecording(filePath)
r:startRecording()
produces the following crash on kindle with a headset with mic.

W/FlurryAgent( 5961): onEndSession called without context from corresponding onStartSession any one understand why? yes, without the findFreeChannel() this code won’t throw the exception. it seems that if I do anything with audio.* functions (like audio.pause, or audio.stop) the exception will be thrown.
