Android Question How to create an app to occupy a large part of the device memory

LucaMs said:

Given that I'm waiting the O.S. kills my app which is in background, for a test, I would develop an app which can occupy a large part (or all) of the device memory .

Any idea?

A loop that adds ImageViews to an activity (in the Activity_Create) containing big images?

it can be done easier.

try something like this

B4X:

For x=0 To 9999
    Dim y(65535) As Byte
Next

or put the dim in a timer

I guess it depends if you stick to java or use these C based object files. they seems to be able to deal with more memory.

It might kill your background app to free resources for the forground one.

Create an app using libGDX and load very big textures. They will be loaded in the native memory, not in the Java VM space. This way you can consume the total memory of the device and see nice crashes.

To have reallistic process killing, Create more than one app to run in the background and load a large bitmap in memory.

Also in the apps, add this line to the manifest:

B4X:

SetApplicationAttribute(android:largeHeap, "true")
