audio and video recording errors in android

I need to record audio and video files to the 3gp/mp4 format in the same file and at the same time. When I run, my application file is created with videofile.3gp but the video does not record to the SD card on the emulator. Does video record on the emulator? If I run this code on an android supported device will I see these errors?

Code and errors below:

    package com.video;

I get the following errors.

The camera API appears to require that many of the sources are set, including the audio, video, and preview surface. The following code is more complete:

recorder = new MediaRecorder(); 
recorder.setPreviewDisplay(previewSurface); 

recorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT); 
recorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT); 

recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP); 
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB); 
recorder.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP); 

recorder.setMaxDuration(1000 * 10); 
recorder.setOnInfoListener(self); 

recorder.setVideoSize(200, 200); 
recorder.setVideoFrameRate(15);

recorder.setOutputFile("/sdcard/test.mp4");

recorder.prepare(); 
recorder.start();

media record requires some H/W feature, such as video encoder(h264, h263)... emulator may not support. just try on your real device
