As a quick answer though to your question though, I will say that:

1. I'm not aware of anyone using TinkerGraph on Android (though I suppose someone could be)
2. Nothing has been done in the development of TinkerGraph to consider the Android environment

I'm also not terribly knowledgeable about Android development to say whether TinkerGraph is Android ready. As for GC problems I've not known TinkerGraph to have such issues but I've not run it in a resource constrained environment so it's hard to say. If you experiment further and wish to share your findings on the gremlin-users list it might help others who are trying to do the same as you. Also, perhaps posting your question there might yield some answers from people who have tried doing this before. Thanks!

> *I have a project that want to use in-memory graph database in Android. I use to tinkerGraph, but I meet GC problem for a while. Will the following statement cause a lot of GC?*
> 1）List<Vertex> children = g.V(id).out("HAS").has("state", statId).not(in("NEXT").has("state", statId)).union(identity(),repeat(out("NEXT").has("state", statId)).emit()).toList();
> 2）g.V(id).out("Visible").repeat(out("HAS")).emit().or(has("package", "com.android.settings").has("text", P.within(forbidList)),has("class", "android.widget.CheckBox")
>  ).repeat(in("HAS")).until(in("HAS").has("class", "android.widget.ListView")).repeat(out("HAS"))
>  .emit().property("forbid", "true").iterate();
> 3）path = g.withComputer().V(v).shortestPath().with(ShortestPath.edges, Direction.OUT).with(target, __.hasId(id)).simplePath().next();
