Question

I’m trying to capture an image using Android Camera via simple activity.

Image is clicked and stored. But the problem is, image is either distorted or fragments of older image is concatenated with the currently clicked image. Image is too dark. Here’s the CODE : –

public class Cameras extends Activity {
    public Camera camera;

    @Override

    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        camera=Camera.open();
        camera.lock();
        Parameters parameters = camera.getParameters();
        parameters.setJpegQuality(1);
        parameters.setJpegThumbnailQuality(1);
        parameters.setJpegThumbnailSize(0,0);
        parameters.setSceneMode("night");
        parameters.setFocusMode("fixed");
        parameters.setPictureSize(640,480);
        camera.setParameters(parameters);
        camera.takePicture(null,null, jpegCallback);
    }


    PictureCallback jpegCallback = new PictureCallback() { // <8>
        public void onPictureTaken(byte[] data, Camera camera) {
          FileOutputStream outStream = null;
          try {
            // Write to SD Card
            outStream = new FileOutputStream(String.format("/sdcard/%d.jpg",System.currentTimeMillis())); // <9>
            outStream.write(data);
            outStream.close();
            camera.unlock();
            camera.release();
            Toast.makeText(Cameras.this,"Picture Taken",Toast.LENGTH_SHORT).show();
          } catch (FileNotFoundException e) { 
            e.printStackTrace();
          } catch (IOException e) {
            e.printStackTrace();
          } finally 
          {

          }
        }
      };


}

Please help regarding this…
I want a neat and clean small size image every time i execute the code.

Thanks… 🙂

    parameters.setJpegQuality(1);
    parameters.setJpegThumbnailQuality(1);

You are requesting very low quality. Try using higher values for quality (like 70)
