How much memory should a typical android application use?

I have developed a file parsing application on the android platform. How do I check how much memory my application is actually using up ? I tried the adb shell cat /proc/meminfo command but this does not give me how much memory my application is using. it just gives general info about the overall memory. And how much memory should an application typically use up ? what is usual or unusual ? Any help is appreciated. Thanks !

You can get the memory usage of your android application with the following command: Assuming you have adb in PATH:

adb shell dumpsys meminfo com.<your.package>

To see live updation of memory in use, you can try

watch "adb shell dumpsys meminfo com.<your.package>"

Hope this helps

Android apps are constrained to a certain amount of memory. As it's quite (insanely?) low, I think you shouldn't feel guilty about using all of it!

The limit is 16 MB on very old devices, 24 MB or 32 MB on newer ones. There doesn't seem to be much info on the size for different devices, and nobody seems to know why the limit is so small when modern phones have 1-2 GB of RAM.

Aha, I found some concrete numbers on the limit:

G1: 16MB

Droid: 24MB

Nexus One: 32MB

Xoom: 48MB

You can use DDMS > Allocation Tracker to track memory usage and Heap Allocation for your app

http://developer.android.com/resources/articles/track-mem.html

To Track the overall memory of a PID you could use following two methods in ActivityManager

To get a PID of your app : 

List<ActivityManager.RunningAppProcessInfo> getRunningAppProcesses ()

and then the MemoryInfo

MemoryInfo[] getProcessMemoryInfo (int[] pids)

you might want to take a look at this one. How do I discover memory usage of my application in Android? Or simply try 

ActivityManager.getMemoryInfo()
