canvas Initialize(panel)

[Gearcam]

I have 2 different Layout Variants 480 X 800 & 320 X 480

On the 480 X 800 this works no problems

On the 320X480 it causes a crash "The application has stopped unexpectedley"

This is the line that causes the problem

cnvtest.Initialize(pnltest)

I have tried alsorts to eliminate this but can not get it sorted
I have checked the size of the panel its correct 320 wide height is 360 which is the same as in the designer.

Is there any reason ?

Please check which error message appears in LogCat (in the right pane). Uncheck the 'filter' option.

So it looks to big ?

Why does it work ok on the bigger screen size ?

460kb is not too much. Which device is it?

Did you try to reboot the device?

 

[Gearcam]

Yes both the HTC wildfire and my emulator have been rebooted
Also the PC ?

It works great on my HTC Desire HD on both the device and the emulator

I have also deleted the emmulator re set it but its still the same ?

This is definetley a memory issue
i removed a lot of the maths data that is stored in very big arrays and it runs

What are the memory limitations for different devices ?

Ok heres the problem in full

I have a panel on the screen
On the panel i have a canvas

On this canvas i draw a full section view through a gear as can be seen here
Gear C.A.M. Gear Design Software its the single gear image bottom left (there are hundreds of short lines for accuracy)

SO far so good

I can then zoom in & out by changing the panel.setlayout command this works fine but the resolution when you zoom in a few times can become poor so i have a refresh button which re draws all lines but within a clippath area hoping this would solve my memory problem, resulution is now restored.

But i still get the problem when zooming in a few times ie the whole bitmap cam become very big hence the clipping i hoped would solve it.

these are the log lines

48372480-byte external allocation too large for this process.
VM won't let us allocate 48372480 bytes

any ideas how to help ?

48372480 bytes is more than 48mb. Most devices limit each process to 16mb.
