5.2 Using the Memory Monitor
Memory is scarce on many MIDP devices. The J2ME Wireless Toolkit includes a
memory monitor that makes it easy to examine the memory usage of your
application. You can see the total memory used by your application and a detailed
listing of the memory usage per object.
To turn on the memory monitor, choose Edit > Preferences... from the KToolbar
menu. Click on the Monitor tab. Check Enable Memory Monitor.
Next time you run the emulator, the memory monitor window pops up, displaying
a graph of your application’s memory usage over time. The memory monitor slows
down your application startup because every object created is recorded.
