regarding garbage collection.Why do we need to call System.gc();?

To fix the issue you can do You don't. As you say, garbage collection is automatic. System.gc() doesn't even force a garbage collection; it's simply a hint to the JVM that "now may be a good time to clean up a bit"
In general, trying to force the garbage collector to do what you want with System.gc() is a hack applied by people who think they know better than they actually do, or as an (attempted) workaround for broken code.

I hope this helps you . Check out this blog post on MSDN: .NET Memory Leak: To dispose or not to dispose, that’s the 1 GB question. The recommendation appears to be that you should be disposing.

Adobe AIR - Garbage collection and system.gc()

around this issue system.gc is a debug only functionality in AIR and Flash player. I think the better thing is to recycle bitmapdata and other objects if you can to avoid gc, and if not call bitmapdata.dispose() and bitmapdata = null as soon as you are done with using them.
If you have bitmap objects of the same size at various times in your project, you can use the same instance of BitmapData to operate on them. This is similar to how ItemRenderers recycle items or how even other platforms like iOS's UITableViewController recycles/reuses UITableViewCell. Garbage collection is not panacea, it should be used when easy programmability is more important than performance.

this one helps. This looks like of the few cases when calling System.gc() is useful. There's no guarantee that it helps, but it's surely worth a try.
You could also try a hack I proposed recently. It's a bit more complicated and may backfire.

Difference between JMX Garbage Collection and a System.gc()?

I think the issue was by ths following , This must be circumstantial (due to it being called at a different point in program's execution or some similar factor) - the Sun's implementation of MemoryMXBean, sun.management.MemoryImpl:
code :
public void gc() {
public static void gc() {

System.gc() for garbage collection

may help you . You can call it. There will be no harm in that. But there is no gaurentee that the memory of object you are expecting immediately gets free or not.
More over JVM runs GC asynchronously and we need not to drive it. JVM intelligent enough to free memory.
