Slow App with Background image

Question

I am making a small game for android. It is working smoothly when its working on a white background but when i want to put a background image, its becoming slower and slower. Fi

Answer 1

I was in the same position as you. I have a very simple app and it has lags when i add some background. Try this app 9-patch-resizer - Transform the image dimensions for all screens

And then comes this tool, that takes a xhdpi PNG file, or 9.png file, and generates ldpi, mdpi and hdpi png files automatically.

When it transoforms the image , move the each file to its own project folder (resources/mipmap-hdpi ,mipmap-xhdpi ...etc)
