I'm confused about how much memory AdMob SDK seem to be using, and where this memory is actually located. Let me explain. I've got two flavors of my app: Free and Paid. Free version has AdMob ads, otherwise the code is almost the same (common Android lib used). I run the apps on my Nexus 4 (Android 4.2.1) and compare memory usage. I look at system memory used by the app in device settings > apps >
