Hello Sir,
I can understand you requirement, that you need to an android app developed for which you have the design ready. However as I checked you asked only for Bangalore's developers, if you get one, that will be good, but in case if you consider me, I can assure you that I will be as good as any one in understanding your requirement and built the application in the exact desired way you require.
Now a days, the location does not matter any more, because I have been working with US clients for various projects which require hardware devices as well, still everything is done quite smoothly.
Talking about my experience in android development, I have working on android since past 3 years and developed various apps based, specifically transport, home automation and IOT as well.
So if you find me worthy enough, we can discuss the detailed requirement, and I am sure you will be more than happy to work with us.
Thanks
