AAOS lunch target: Cuttlefish, Trout or AVD

[Jakub Drabik]

Hello community,

I've come across a couple of unclear areas regarding building and launching AAOS, specifically - choosing the right target. 

Based on the documentation here, it's advised to use an AVD build. However, in general, the recommended target for AOS builds appear to be Cuttlefish (by quite obvious reasons here). By digging a bit more into the documentation I found Trout, being based on Cuttlefish (here). Now, when I hit `lunch`, I can see a lot of different targets for AAOS, basically for AVD, Cuttlefish and Trout. 

So which one shall I actually use? 

1. AVD sdk_

2. AVD aosp_

3. Cuttlefish

4. Trout

My goal is to run a couple of proof of concepts for a custom VHAL implementation and the GUI changes. 

Thank you very much for your help!
