In my application I need to resize the bitmap to imageview size. I tried the following code and I am getting exception.

Bitmap bmp = Bitmap.createBitmap(bmp, 0, 0, bmp.getWidth(), bmp.getHeight(), aMatrix, false);
Bitmap.createScaledBitmap(bmp, MyImageview_wt, MyImageview_ht, false);
MyImageview.setImageBitmap(bmp);

Pls help

Thanks

    Try with the following code

    public static Bitmap resizeBitMapImage1(String filePath, int targetWidth,
                int targetHeight) {
            Bitmap bitMapImage = null;
            // First, get the dimensions of the image
            Options options = new Options();
            options.inJustDecodeBounds = true;
            BitmapFactory.decodeFile(filePath, options);
            double sampleSize = 0;
            // Only scale if we need to
            // (16384 buffer for img processing)
            Boolean scaleByHeight = Math.abs(options.outHeight - targetHeight) >= Math
                    .abs(options.outWidth - targetWidth);
    
            if (options.outHeight * options.outWidth * 2 >= 1638) {
                // Load, scaling to smallest power of 2 that'll get it <= desired
                // dimensions
                sampleSize = scaleByHeight ? options.outHeight / targetHeight
                        : options.outWidth / targetWidth;
                sampleSize = (int) Math.pow(2d,
                        Math.floor(Math.log(sampleSize) / Math.log(2d)));
            }
    
            // Do the actual decoding
            options.inJustDecodeBounds = false;
            options.inTempStorage = new byte[128];
            while (true) {
                try {
                    options.inSampleSize = (int) sampleSize;
                    bitMapImage = BitmapFactory.decodeFile(filePath, options);
    
                    break;
                } catch (Exception ex) {
                    try {
                        sampleSize = sampleSize * 2;
                    } catch (Exception ex1) {
    
                    }
                }
            }
    
            return bitMapImage;
        }
