Question

I use below code to get the file pathof image in sd card.

File[] f = (Environment.getExternalStorageDirectory()).listFiles();
int i;
for(i = 0; i < f.length; i++) {
if(f[i].isFile()) {
if(isPhoto(f[i].getName())) {
Filepath.add(f[i].getAbsolutePath());
}
}
else {
//recursive
}
}

I want to get the path of the thumbnail of image by know original image path.
How to do it?

You can make your own thumbnail image:

byte[] imageData = null;

    try     
    {

        final int THUMBNAIL_SIZE = 64;

        FileInputStream fis = new FileInputStream(fileName);
        Bitmap imageBitmap = BitmapFactory.decodeStream(fis);

        imageBitmap = Bitmap.createScaledBitmap(imageBitmap, THUMBNAIL_SIZE, THUMBNAIL_SIZE, false);

        ByteArrayOutputStream baos = new ByteArrayOutputStream();  
        imageBitmap.compress(Bitmap.CompressFormat.JPEG, 100, baos);
        imageData = baos.toByteArray();

    }
    catch(Exception ex) {

    }
