In this performance tutorial we use the BitmapFactory.Options inSampleSize for loading smaller images with subsampling┬átherefore saving memory & cpu resources, resulting in more responsiveness especially in scrolling. Method Create a scale factor algorithm private int calculateInSampleSize(BitmapFactory.Options bmOptions) { final int photoWidth = bmOptions.outWidth; final int photoHeight = bmOptions.outHeight; int scaleFactor = 1; if(photoWidth > TARGET_IMAGE_VIEW_WIDTH […]
