how to get compressed image uri for gallery Image?


I am working on project where there is an need for image to be compressed and need get Uri for that compressed image. The problem is when I try to compress image from gallery it is creating one more image which is compressed along with the original image with different resolution how can achieve like I should have only one image reference in gallery that is also original image not the compressed image. Please find my code snippet below with which I have tried

    public static Bitmap getResizedBitmap(Bitmap image, int maxSize) {

    int width = image.getWidth();
    int height = image.getHeight();

    float bitmapRatio = (float) width / (float) height;
    if (bitmapRatio > 1) {
        width = maxSize;
        height = (int) (width / bitmapRatio);
    } else {
        height = maxSize;
        width = (int) (height * bitmapRatio);
    }

    return Bitmap.createScaledBitmap(image, width, height, true);

}

private static Bitmap rotateImage(Bitmap img, float degree) {
    Matrix matrix = new Matrix();
    matrix.postRotate(degree);
    Bitmap rotatedImg = Bitmap.createBitmap(img, 0, 0, img.getWidth(), img.getHeight(), matrix, true);
    //img.recycle();
    return rotatedImg;
}

private static Bitmap rotateImageIfRequired(Context context, Bitmap img, Uri selectedImage) throws IOException {

    InputStream input = context.getContentResolver().openInputStream(selectedImage);
    ExifInterface ei;
    if (Build.VERSION.SDK_INT > 23)
        ei = new ExifInterface(input);
    else
        ei = new ExifInterface(selectedImage.getPath());

    int orientation = ei.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);

    switch (orientation) {
        case ExifInterface.ORIENTATION_ROTATE_90:
            return rotateImage(img, 90);
        case ExifInterface.ORIENTATION_ROTATE_180:
            return rotateImage(img, 180);
        case ExifInterface.ORIENTATION_ROTATE_270:
            return rotateImage(img, 270);
        default:
            return img;
    }
}

public static Uri compressedImageUri(Uri selectedImage, Context context) {
    try {

        InputStream imageStream = null;
        try {
            imageStream = context.getContentResolver().openInputStream(
                    selectedImage);
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }
        Bitmap original = BitmapFactory.decodeStream(imageStream);
        //Bitmap bmp = getResizedBitmap(original, 500);
        Bitmap rotateBitmap = rotateImageIfRequired(context, original, selectedImage);
        Bitmap bmp = getResizedBitmap(rotateBitmap, 500);
        String path = MediaStore.Images.Media.insertImage(context.getContentResolver(), bmp, String.valueOf(System.currentTimeMillis()), null);

        return Uri.parse(path);
    } catch (Exception e) {
        Log.d("error", e.getLocalizedMessage());
    }
    return null;

}

Solution

  • Use this Compressor.class

    File imgFile = new File(uri.getPath());
    File  compressFile = Compressor.getDefault(getContext()).compressToFile(imgFile);
    

    You may need some other class so please check compressor package. Hope this will help you.
