Scoring app for Android

So, I need an option for composing and orchestrating on the go on my Android tablet.
Tight integration with major scoring app is a big plus, but MuscXML in/out is doable.
No need for fancy formatting/engraving but pro solutions for staves, instruments, input-options etc.
What are my options?

I think probably the most accomplished music notation app for Android devices is likely to be PreSonus Notion:

Thanks! Yes, that seems like my best bet.
