I am making an application in blackberry,
Here i want to know the current cpu usage and memory usage. How to find that?
Refer this link Memory
Memory.getRAMStats().getFree();
Memory.getRAMStats().getAllocated());

we want display statistics of the application. I have application running. Every min it has to display CPU utilization, Memory utilization and Battery usage of my application. Im able to get overall CPU and memory Utilization. How do we get only for my application. Even I can get battery level but how can i get how much battery it has used by my application. It should be like Activity monitor how it displays against each process. All these information i have to display in iOS application. Thanx in advance.
Most of this is already implemented in Nimbus lib http://latest.docs.nimbuskit.info/NimbusOverview.html
You can other use it from the box or search there for ideas and solutions.

I am developing an app that is crashing due to an excess of memory usage. I would like to know the amount of memory that is being used by each active thread so that I can decide which allocated or drawn in screen elements release or remove from view. Is there a way to obtain it?
I have tried using mach.h library but with mach_task_self() I can only access the memory used by the whole application.
Thanks in advance
I think what you want is logMemUsage().
You can check the Answer from this Question :
Watching memory usage in iOS
I think you can get something from this Documentation also :
Understanding and Analyzing iOS Application Crash Reports
If you want to check Memory Usage While Application is Running then use Instruments. :
Using Instruments you can check how much memory your app is using. In Xcode4, use 'Profile' build, choose Leaks, then click the Library button in the toolbar and add the Memory Monitor instrument.
If you really don't want to use Instruments then you can use Custom Class UIDeviceAdditions :
Get current Memory usage
Hope it's Enough.
You can't because threads share the heap. Threads are created with a 512KB stack space, with memory pages allocated as needed. Other than that, there is no memory per thread value stored anywhere.
I'd like to track memory usage thru the runtime of my image. I'd like to frequently measure the current memory usage.
And the Smalltalk code:
Smalltalk vmParameterAt: 3
WorldMenu->Tools->MemoryMonitor
we are planing an app for blackberry app world and will have to load lots of textures and audiofiles.
so we need to know how much memory the app can really allocate for a smarthphone with 64MB (RAM)
thx for answers!
You can also check available memory before load:
MemoryStats.html#getFree() - Amount of memory/strorage free
Memory.html#getFlashFree() - Bytes of free flash
FileConnection.html#availableSize() - The available size in bytes on a file system
You can try to allocate as much memory as you need. If there isn't enough available, it will throw an OutOfMemory runtime exception when you try to allocate memory. That said, I don't think your app would be a good "citizen" on the phone if it tries to grab all available RAM.
