问题 i'm trying to save the recorded audio files in a folder that i wanted it to be rather then the default folder. but somehow i failed to do so. my code: Intent recordIntent = new Intent(MediaStore.Audio.Media.RECORD_SOUND_ACTION); Uri mUri = Uri.fromFile(new File(Environment.getExternalStorageDirectory(), "/Record/sound_"+ String.valueOf(System.currentTimeMillis()) + ".amr")); recordIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, mUri); startActivityForResult(recordIntent, RESULT_OK);

问题 I am using Apple's SpeakHere example in my project. I can record voice and play without problems.. The problem occurs when I change the view controller where I am using AVAudioPlayer to play recorded voices..

Thanks in advance. 来源： https://stackoverflow.com/questions/17691616/speakhere-voice-recorder-fails-after-avaudioplayer-in-ios
