Strange Memory Error

[Smee]

I have installed an app to a xoom and during testing i open a new activity screen and close it multiple times. On one tablet it works fine no matter how many times i do it but on another after 3 goes back and forward i get a memory error. There is no major bitmaps loaded except for the screen background but it works fine on one device and crashes on another.

Is it possible to have bad memory chips? The one causing a problem is a brand new device!!!!

It is not related to bad memory chip.
It is possible that this device allocate less memory for each process.
You should use LoadBitmapSample instead.

Thanks for the fast reply Erel,

I have changed the code from

NewBitmap1.Initialize(File.DirAssets,"menu2.jpg")
pnlMaintenance.SetBackgroundImage(NewBitmap1)

to this

Activity.SetBackgroundImage(LoadBitmapSample(File.DirAssets, "menu2.jpg", Activity.Width, Activity.Height))

However the background does not show. Am i missing something here?


OOOOpppsss

I noticed.

It should have been


pnlMaintenance..SetBackgroundImage

Thank you, that seems to have fixed that problem. Now to the next

 

[Erel]

I think you should set pnlMaintenance background.
