I am working on AR project where i need to capture the current frame and save it to gallery. I am able to get the image using Frame class in AR core , but the format of image is YUV_420_888. I have already tried lots of solutions to covert this to bitmap but couldn't able to solve it.

This is how I convert to jpeg.

public Bitmap imageToBitmap(Image image, float rotationDegrees) {



    assert (image.getFormat() == ImageFormat.NV21);



    // NV21 is a plane of 8 bit Y values followed by interleaved  Cb Cr

    ByteBuffer ib = ByteBuffer.allocate(image.getHeight() * image.getWidth() * 2);



    ByteBuffer y = image.getPlanes()[0].getBuffer();

    ByteBuffer cr = image.getPlanes()[1].getBuffer();

    ByteBuffer cb = image.getPlanes()[2].getBuffer();

    ib.put(y);

    ib.put(cb);

    ib.put(cr);



    YuvImage yuvImage = new YuvImage(ib.array(),

            ImageFormat.NV21, image.getWidth(), image.getHeight(), null);



    ByteArrayOutputStream out = new ByteArrayOutputStream();

    yuvImage.compressToJpeg(new Rect(0, 0,

            image.getWidth(), image.getHeight()), 50, out);

    byte imageBytes = out.toByteArray();

    Bitmap bm = BitmapFactory.decodeByteArray(imageBytes, 0, imageBytes.length);

    Bitmap bitmap = bm;



    // On android the camera rotation and the screen rotation

    // are off by 90 degrees, so if you are capturing an image

    // in "portrait" orientation, you'll need to rotate the image.

    if (rotationDegrees != 0) {

      Matrix matrix = new Matrix();

      matrix.postRotate(rotationDegrees);

      Bitmap scaledBitmap = Bitmap.createScaledBitmap(bm,

              bm.getWidth(), bm.getHeight(), true);

      bitmap = Bitmap.createBitmap(scaledBitmap, 0, 0,

              scaledBitmap.getWidth(), scaledBitmap.getHeight(), matrix, true);

    }

    return bitmap;

  }
