我正在尝试在服务中使用MediaRecorder来录制声音.但是它在开始时会产生1秒的延迟(静音).我该如何摆脱呢？我尝试使用RehearsalAudioRecorder仍然没有运气.如果有人已解决此问题,请先提出建议.

开始

Intent serviceIntent = new Intent();            serviceIntent.setAction("com.soundrecoder.RecorderService");            serviceIntent.putExtra("audiofile", path);            serviceIntent.putExtra("state", true);            startService(serviceIntent);

停止

Intent serviceIntent = new Intent();            serviceIntent.setAction("com.soundrecoder.RecorderService");            serviceIntent.putExtra("state", false);            startService(serviceIntent);

RecorderService.java文件

public class RecorderService extends Service{    private static final String TAG = null;    private static MediaRecorder mRecorder;    public voID onCreate() {};    public voID onStart(Intent intent, int startID)    {        boolean isstart = intent.getBooleanExtra("state", false);        if (isstart) {            mRecorder = new MediaRecorder();            mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);            mRecorder.setoutputFormat(MediaRecorder.OutputFormat.THREE_GPP);            mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);            mRecorder.setoutputfile(intent.getStringExtra("audiofile"));            try {                mRecorder.prepare();            } catch (IllegalStateException e) {                Log.e(TAG,e.getMessage());            } catch (IOException e) {                Log.e(TAG,e.getMessage());            }            try {                mRecorder.start();            }            catch (IllegalStateException e) {                Log.e(TAG, e.getMessage());            }        }        else if (!isstart) {            mRecorder.stop();            mRecorder.reset();        }    }    @OverrIDe    public IBinder onBind(Intent intent) {        return null;    }}

解决方法:

我找到了RehearsalAudioRecorder解决方案

public voID onStart(Intent intent, int startID) {        boolean isstart = intent.getBooleanExtra("state", false);        if (isstart) {            acquireWakeLock();            int i = 0;            do {                if (mRecorder != null)                    mRecorder.release();                 mRecorder = new RehearsalAudioRecorder(false, 0, 0, 0, 0);            } while ((++i < 44100)                    & !(mRecorder.getState() == RehearsalAudioRecorder.State.INITIAliZING));            mRecorder.setoutputfile(intent.getStringExtra("audiofile"));            mRecorder.prepare();            mRecorder.start();        } else if (!isstart) {            if(mRecorder != null) {                mRecorder.stop();                mRecorder.release();                mRecorder = null;            }            releaseWakeLock();        }    }
