Best way to load assets in android java

Question

I have one android activity with a lot of calculations and everything is ok, but in the final version of my project I need to load a lot of bitmaps and sounds in the same activity and it gets a lot slower than it should be.. Sometimes the activity chrashes itself.

So, is there any advice how should I load all the assets? Should I declare them in separate class, or what?

Answer 1

Basically you only load those assets when you need them and unload them if you do not need them. (Lazy Loading)

Because mobile has limited memory and I am imagining your files are really big you must be careful on how you will manage those files.

For image I recommend this link and try to optimize your image as good as possible

For sounds kindly look at this class and this discussion about loading sound files
