Memory allocation per app (Android)

[jay73]

Is there a maximum amount of memory (RAM) that a app can use when running on android? I've searched on the net and have read that older devices could use only 16mb then this changed to 24mb or 32mb for newer devices. I've also read that a app can use the total amount of free memory on the device. I don't know which of these is the right answer.

When developing a app for android is using the fusion debugger an accurate way of determining how much memory will be used? I notice that a new and empty project uses 37mb, that's before any objects and conditions.

Also, is there a way to load frames or other data in stages to reduce the amount of memory? For example load each level and its objects when they are needed rather than load everything at once.

Any info appreciated.

Nobody knows if there is a limit on the amount of RAM for a app? This is important because if there is, 37mb is lost to the fusion runtime before any app is even made and this is more than the 24mb and 32mb max RAM quoted amounts.

You are talking about the heap the VM heap from device , yes each device have it own heap size that depends on manufacturers, device hardware , android version but they are like you mentioned above.

here is an application that will check the VM size https://play.google.com/store/apps/d...eapsizechecker

normally you don´t need to touch the heap, unless you have a lot numbers of variables and object, do you feel you need it?

comment from others

"The heap (in Java) stores dynamically allocated variables, such as objects. when the heap is running low on memory, the JVM will run garbage collection. Garbage collection uses processing cycles, which will slow down your phone. In case you're wondering, the other place in memory where things are stored is called the stack, which stores arguments and parameters."

Thanks FVivolo. There's no way to set the heap from fusion is there, or is this done automatically?
