android - Why does BitmapFactory.decodeResource scale my image? -


i have image 120x120px located in /res/drawable/ directory. size required devices.

to load bitmap, using following:

bitmap tmpbmp = bitmapfactory.decoderesource(getresources(), r.drawable.myimage);

the issue when measure tmpbmp, size 360x360px. know how scale down 120x120 need, waste of processing time, although minimal.

i assuming has screen densities, since resource in density-less directory.

what reason decoderesource scaling image? , how stop doing so?

the default drawable directory assumes images need scaled default mdpi size. put images in drawable-nodpi if want disable resource scaling.

do note 120x120px image, if displayed on screen, 3x smaller on xxhdpi device compared mdpi device (as there 3 times many pixels per inch).
