You should decode the image uri on onActivityResult() method. Call this method to decodeBitmap.

/**
     * This is very useful to overcome Memory waring issue while selecting image
     * from Gallery
     * 
     * @param selectedImage
     * @param context
     * @return Bitmap
     * @throws FileNotFoundException
     */
    public static Bitmap decodeBitmap(Uri selectedImage, Context context)
            throws FileNotFoundException {
        BitmapFactory.Options o = new BitmapFactory.Options();
        o.inJustDecodeBounds = true;
        BitmapFactory.decodeStream(context.getContentResolver()
                .openInputStream(selectedImage), null, o);

        final int REQUIRED_SIZE = 100;

        int width_tmp = o.outWidth, height_tmp = o.outHeight;
        int scale = 1;
        while (true) {
            if (width_tmp / 2 < REQUIRED_SIZE || height_tmp / 2 < REQUIRED_SIZE) {
                break;
            }
            width_tmp /= 2;
            height_tmp /= 2;
            scale *= 2;
        }

        BitmapFactory.Options o2 = new BitmapFactory.Options();
        o2.inSampleSize = scale;
        return BitmapFactory.decodeStream(context.getContentResolver()
                .openInputStream(selectedImage), null, o2);
    }
