三星手机上录音崩溃的问题
某些三星手机的音频驱动好像是改过的，在 HTC 手机上跑的好好的程序，拿到三星上就录音崩溃。我目前的手机是三星GT-I8150，我的源码如下：
public class AndroidAudioRecordManager{ public int frequency =8000; public int channelConfiguration = AudioFormat.CHANNEL_CONFIGURATION_MONO; public int audioEncoding = AudioFormat.ENCODING_PCM_16BIT; int recBufSize, playBufSize; AudioRecord audioRecord; boolean isRecording = false; private long filterCtxPtr = 0; Thread recordThread=null; private native void putAudioData(long filterCtxPtr, byte[] buffer, int dataLen); public void startParametersFromFilter(long filterCtxPtr, int rate, int channel, int bits) { this.filterCtxPtr = filterCtxPtr; frequency = rate; recBufSize = AudioRecord.getMinBufferSize(frequency, channelConfiguration, audioEncoding); audioRecord = new AudioRecord(MediaRecorder.AudioSource.MIC, frequency, channelConfiguration, audioEncoding, recBufSize); isRecording = true; recordThread=new AudioRecordThread(); recordThread.start(); } public void stopFromFilter() { isRecording = false; try { recordThread.join(); } catch (InterruptedException e) { } } class AudioRecordThread extends Thread { public void run() { android.os.Process.setThreadPriority(-19); try { byte[] buffer = new byte[recBufSize]; int rstat=audioRecord.getRecordingState(); int dstat=audioRecord.getState(); if(dstat!=AudioRecord.STATE_INITIALIZED) { return; } Thread.sleep(1000); audioRecord.startRecording(); while(isRecording) { int bufferReadResult = audioRecord.read(buffer, 0, 320); putAudioData(filterCtxPtr, buffer, bufferReadResult); } audioRecord.stop(); } catch (Throwable t) { } finally { audioRecord.release(); audioRecord=null; } } }};
