Differences between Android NetBEANS plugin and Eclipse plugin?

I think its a matter of personal preference, but I think Eclipse with ADT plugin is recommended by Google for good reasons.

ADT simplifies things by generating build scripts for you and allows you to drag and drop files into your project and auto generates references in R.Java file.

It sounds to me that you might be new to Android/Java development? If that's the case then my personal opinion is stick with the Google recommendations. It saves you a lot of time getting your first android application up and running and I think that's the goal for most people starting a new development language.

I develop almost everything in NetBeans. However, for Android application development, Eclipse is the better IDE to use, as it simplifies a lot of simple tasks.

I prefer NetBeans generally, but Eclipse is way more tailored to Android development than NetBeans at the moment.

You will be more productive :

Android offers an Eclipse Plugin per their web site. Check out this link on the Android site: http://developer.android.com/sdk/installing/index.html. For the beginning programmer new to Android the tight integration will allow ramp up to speed faster. One of the most highly regarded reference works by Reto Meier "Professional Android 4 Application Development" recommends Eclipse with the ADT Plug-in and makes no mention of Netbeans.

The ADT Plugin includes an Android Project Wizard, Virtual Device Manager and Emulator and especially the layout and resource editors for XML. Therefore you get the tightest integration to make it easiest for a programmer to ramp up quickly and begin to develop Android applications.

Android recommends Eclipse and the plugin, as do respected developers like Reto Meier over Netbeans. (Despite the fact that a plugin does exist for Netbeans as helpfully provided below.)

My recommendation if you are new to Android development, use the Eclipse with ADT Plug-in. If you are a Netbeans veteran, stick with that.
