Android: camera issue not available

I try to capture a video, and the procedure throws an exception when execution reaches the recorder.prepare () statement:

private void recordVideoStart(){ if(recorder != null) { recorder.stop(); recorder.release(); } File file = new File("/sdcard/videoTest.3gpp"); try { file.createNewFile(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } recorder = new MediaRecorder(); recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA); recorder.setAudioSource(MediaRecorder.AudioSource.MIC); recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP); recorder.setOutputFile(file.getAbsolutePath()); recorder.setVideoSize(176, 144); recorder.setVideoFrameRate(15); //recorder.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP); recorder.setVideoEncoder(MediaRecorder.VideoEncoder.DEFAULT); recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB); recorder.setPreviewDisplay(videoPreview.getSurface()); try { recorder.prepare(); } catch (IllegalStateException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } recorder.start(); }

Looking at LogCat, I noticed the line "Camera unavailable."

Does anyone know what might be wrong here and how to enable video capture?

Thanks!

You need to install the camera on the recorder.

 recorder.setCamera(Camera.open());

You added in AndroidManifest.xml:

 <uses-permission android:name="android.permission.CAMERA" />

Verify that the following permissions are specified in the manifest. WRITE_EXTERNAL_STORAGE is required to write to our SD card.

  <uses-permission android:name="android.permission.RECORD_AUDIO"></uses-permission> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission> <uses-permission android:name="android.permission.CAMERA"></uses-permission> <uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission> <uses-feature android:name="android.hardware.camera" /> <uses-feature android:name="android.hardware.camera.autofocus" />
