Read Images Byte By Byte From Android Internal Storage Takes Too Much Time

I'm trying to display images from android internal storage, I have only 4images(the images are screen shots taked before), I display these images in a GridView, it works, but it ta

Solution 1:

To be faster is indicated to reduced the image size. It can be done using the Bitmap decodeFile (String pathName, BitmapFactory.Options opts)

Look this example:

publicBitmapgetReducedBitmap(String path) {
    BitmapFactory.Options opt = newBitmapFactory.Options();
    opt.inSampleSize=4; // reduced the image to 1/4 of the orignal sizereturnBitmapFactory.decodeFile(path, opt);
}

Solution 2:

Use BitmapFactory.decodeFile(String) instead. Then all of this file reading is handled for you.
