Android App - IT development partner needed

I want to build a mobile app in Android , iPhone and Windows. OK with hybrid as long there is no user experience problem. Current location of the person needs to be shown for family and friends. Friends can be in contact list or not. Need to sign a NDA. Prefer someone in India - especially Bangalore. But location not a limit for the right candidate I want someone who runs the company rather than individuals working in some other company. Because I need long term partner. Infact I am ok to give equity if the business going good. I want the support from development, deployment to mobile apps, cloud ,etc. Need to continue relations ship later on I want the services to be written only in Java - preferrably Spring MVC or Jboss forge
