added Android emulator starter, stopper and unlocker

@kpiwko 
because I am using another interaction above and I do not know how to mix them together.

Does interaction work this way?

```
.when("Do you wish to create a custom hardware profile \\[no\\]")
.replyWith("no" + System.getProperty("line.separator")).build()
.when("(?s).*").printToOut()
```

so I am safe to chain that and print whatever comes but that question about hardware profile?
