App crashes when mutiple (large) images are loaded.
Hi. I'm designing an android app for my university project. It's a car racing game. I'm using a image of resolution 8000x8000 as racing track. Now I'm trying to add another image as startup image. But after loading this image it crashes everytime when I open the app. The problem is I guess my smartphone's RAM can't handle that amoun of data. How can I overcome this problem? It's almost deadline and it's driving me crazy. :(

I had a similar problem loading multiple images before. I don't know much about memory ram limitations, meaning I am not sure how to calculate the available memory taken in a process. However downsizing my images did the trick, at least for my project requirement and the image quality wasn't noticeably affected.
I hope this helps,

@Tahsin=== I dont think that it is possible to do so; but your 8000 image can be divided in a lot of images, like tiles in a map, that you can call when it is necessary (eg when the user scrolls); i have done that and finally seen that 9 "little" images only are necessary.
@akenaton===You mean I have to divide my image into a lot other images? Do I have to do this manually(using photoshop or MS paint) or is there any function available in Processing to do so?
@Tashin===
photoshop of course because if you create a function for that you have to load the big image before calling it!
If your slices are going to be 8000x8000 in total that's going to be more memory than using a single image... However if there are repeated areas of the main image then you can use tiles.

For instance...
@koogs=== yes, in total (in the app package or on the sd card) it will be probably a little more; yet, at runtime, if you load only 9 tiles among all it is not at all the same...
I have an idea. I'm using a PImage variable and each time I need to use an image, I'm going to make that image variable=null and then load the required image. Thus I can avoid loading two images at a time.
I've already given it a try. The thing is sometimes it works and sometime it doesn't.
