boostr.in questions - Question:OutOfMemoryError of Bitmap in Android


I am developing one demo application in which I am playing so many images(Bitmaps). I am using Global Bitmap object for display same image in to more than one Activity. But using that I am geting OutOfMemoryError while I am trying to create Bitmap using Bitmap.createBitmap(...). I tried using this code but still I am getting same error and it is crashing my application and through the OutOfMemoryError.

I am stuck on this. Can anyone has any solution to avoid this.??

Thanks in advance.

I am getting bitmap after cropping the image so that I am using below code for decode the bitmap size.

public static Bitmap loadFromBitmap( Context context, Bitmap b, int maxW, int maxH ) throws IOException {
        final BitmapFactory.Options options = new BitmapFactory.Options();
        Bitmap bitmap = null;
        options.inScaled = false;
        options.inPreferredConfig = Bitmap.Config.RGB_565;
        options.inJustDecodeBounds = true;
        BufferedInputStream stream = null;
        ByteArrayOutputStream outstream = new ByteArrayOutputStream();
        b.compress(CompressFormat.JPEG, 100, outstream);
        InputStream is = new java.io.ByteArrayInputStream(outstream.toByteArray());

        stream = new BufferedInputStream(is, 16384 );
        if ( stream != null ) {
            options.inSampleSize = calculateInSampleSize( options, maxW, maxH );
            stream = null;
            stream = new BufferedInputStream(is, 16384 );
        } else {
            return null;
        }
        options.inDither = false;
        options.inJustDecodeBounds = false;
        options.inPurgeable = true;
        bitmap = BitmapFactory.decodeStream( stream, null, options );
        if ( bitmap != null ) bitmap = BitmapUtils.resizeBitmap( bitmap, maxW, maxH );
        return bitmap;
    }

    public static int calculateInSampleSize(BitmapFactory.Options options, int reqWidth, int reqHeight) {
        // Raw height and width of image
        final int height = options.outHeight;
        final int width = options.outWidth;
        int inSampleSize = 1;

        if (height > reqHeight || width > reqWidth) {

            // Calculate ratios of height and width to requested height and width
            final int heightRatio = Math.round((float) height / (float) reqHeight);
            final int widthRatio = Math.round((float) width / (float) reqWidth);

            // Choose the smallest ratio as inSampleSize value, this will guarantee
            // a final image with both dimensions larger than or equal to the
            // requested height and width.
            inSampleSize = heightRatio < widthRatio ? heightRatio : widthRatio;
        }

        return inSampleSize;
    }
