Title: Texture size crash on Android 4.2.1 (Nexus4)
Post by: Raswr on February 06, 2013, 02:18:03 pm

Hi!

I recently switched to a Nexus 4 phone with Android 4.2.1 and i'm getting some weird crashes while loading textures. All my textures are square of 2 size, but I'm getting errors like these when executing Texture aux=new Texture(res.getDrawable(id),alpha); and after that activity stops

256x256 size texture:

Last time I tested my app on my Samsung Galaxy S plus it worked fine, now a relative has that phone so i can't test it again in it until tonight! Any ideas?

Thanks :)

Don't use drawable to store your textures. Use either raw or the assets directory. Images in drawable can get scaled at load time by Android, which is what happens here.

Wow! how didn't I know that? It never happened to me on my other phone, now I'm sure this one is upscaling the images as it has higher resolution, makes sense. Time for me to fix that, thanks :) (and sorry, this  was quite unrelated to jpct-ae)

Depending on which folder you stored your texture, it might be upscaled or downscaled, again depending on target device. If you stored it in the drawable folder, then for medium density devices (which is the baseline for android) it won't be rescaled. That's probably the reason it worked on your Galaxy S but not on your nexus 4 (which would have a higher density)
