GP poster is just trolling, with his "Eclipse, like all free IDE's, sucks" comment. You don't notice him mentioning his own environment.
The only other strong suggestion he can make is Android Studio, which instead of bundling Android SDK with Eclipse it bundles Android SDK with IDEA. Which would be fine, if it wasn't languishing in bug reports of its own, new major releases every week, breaking due to Gradle configurations that cause hair-pulling (what the fuck is Gradle and what was wrong with Ant and Maven for dependency management), etc etc. And forget trying to migrate from Eclipse with the SDK over to Android Studio. For God's sake, even when Google I/O was going on, the current builds of Android Studio on offer still didn't work any better than the Eclipse SDK. Life apparently is no better in the Mac world but I don't have experience there.
Don't get me wrong, I love Android, I have 3 Android devices, I'm interested in developing Android apps personally. I'm not knocking Java, I use it. I'm not knocking existing IDEs, I use them. What I'm knocking is the constant moving target status of Android where things change so fucking quickly their own devs can't even keep up with their own IDE bundles or their own documentation. As a potential Android developer, everything I run into is a turnoff. Look at the project and look at all the open issues with the IDE tools and the SDK (forget API and device bugs, those are all to be expected, I'm talking serious problems with the developer tools only). I don't have time to deal with that shit for fun.
