How to identify Memory Leaks in Android?

I have developed a simple application before testing it i want to check whether any memory leaks are there in the application. I don't know how to identify the leaks in Android. I am using Eclipse IDE for development.

Is there a good introduction into finding memory leaks in Android apps somewhere?

Once you test an application through the Eclipse Emulator, you will be informed about any memory leaks by going through the LogCat.

Any memory leaks will be highlighted in red as far as I know.

No. Exceptions will be shown in red. Sometimes if you are leaking an object that android knows about it will throw an exception. If there is nothing in logcat your app can still have a lot of "leaked" memory

Sorry Jansuz, I cant agree with that... I have discovered many leaks from open cursors and the likes that have not thrown an exception but that have shown up in the logcats.
