android多媒体录制

还是先看代码，用一种最笨的方式实现了录音的功能： 

try { 
String path = "/sdcard/recorder.amr"; 
MediaRecorder recorder = new MediaRecorder(); 
recorder.setAudioSource(MediaRecorder.AudioSource.MIC); 
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP); 
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB); 
recorder.setOutputFile(path+name); 
recorder.prepare(); 
recorder.start(); 
try { 
Runnable.wait(10000); 
} catch (Exception exp) { 
exp.printStackTrace(); 
} 
recorder.stop(); 
recorder.release(); 
} catch (IllegalStateException e) { 
e.printStackTrace(); 
} catch (IOException e) { 
e.printStackTrace(); 
} 

10秒钟哦，等也得等，不等也得等，不用线程怎么行。 

录像就是Audio+Video，所以还要加点东西，看代码： 
path = "/sdcard/v.3gp"; 
recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA); 
recorder.setAudioSource(MediaRecorder.AudioSource.MIC); 
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP); 
recorder.setVideoSize(176, 144); 
recorder.setVideoFrameRate(15); 
recorder.setVideoEncoder(MediaRecorder.VideoEncoder.H263); 
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB); 
recorder.setOutputFile(path); 
理论上是没错的，可我用模拟器测试录制视频还是会报错
