Out Of Memory Exception In Textview.setbackground Resource In Android

I am trying to place an image as background in my TextView. I want the image to get changed by pressing a button. At the first image gets loaded but when I try for next time it say

Solution 1:

image memory usage is based on multiple things:

1. resolution of the image.
2. where the image file is located (the density qualifier of the drawable folder) compared to on which screen density the app is running on.
3. which bitmap format you used .
4. whether or not the image is 9-patch image.

so , for example, if you have a 100x100 image, and the file is in "drawable-mdpi" yet it runs on an xhdpi device , and the bitmap format is the default one, and it's not a 9-patch image, the bitmap would take:

100*100 * 4 *4 = 160,000 bytes.

the 100*100 is because of the number of pixels for width and height.

the first 4 is because on the default bitmap format, each pixel takes 4 bytes.

the second 4 is because the density is 2 times larger in both width and height (2*2=4).

so, if this is the only code you show, i think you use too much memory because of your images.

one thing that you could do is to downsample them.
