When i started to programming in Java (for Android purpose) in IntelliJ instead of Eclipse, i have found that DDMS tool i was working with in Eclipse is missing in IntelliJ. My searches in web reveal that such tool wasn't implemented in IntelliJ.
But solution is simple: because the DDMS tool belongs to Android SDK and not to programming environments, it can be provided by Android SDK itself.
So if we will go to directory with an Android SDK, we will find ddms.bat inside bin directory. In my case in :
C:\Dev SDK\android-sdk-windows\tools\ddms.bat
