Out of memory when switching between screens

Discuss
#1

I have a problem with my app.

When i jump between 2 screens several times (depending on device memory), then the app crashes with an Out of memory error.

in logcat i get this:

Does anybody know what I have done wrong, or what can cause this error.
When I go form screen2 to screen1, I use Close screen2, simply going to the screen without closing just seems to make it worse.

you have to switch screens correctly, this is the right method for switching between screens,

It has to do with images, how big are they? Load images when needed and unload when not needed

My app is automatically stopping this is the report

I have tried to decrease image size, and that just postpone the problem.

How can I unload an image?.

#5

I hope you mean decrease in px size, because that’s the most important thing here, so

and how many are loaded at the same time

#6

They are 1000x1000 and about 53k in size.

It loads 3-4 of those on each screen.

(It is on a tablet, not a phone)

#7

Use images as big they need to be.

If tablet is 720x1280px then the images is to big for it, if you use it on a fourth portion of the screen then it is definitely too big for it, etc…
