I have been developing Android apps for the last 2 years and have worked on an Office Automation App for a Chartered Accountant using Java/Eclipse/Android Studio incorporating Material Design also.
We can use SQLite and MySQL databases, and PHP for web services.
I am also currently working on a GPS project using HTML5/Javascript in the Intel XDK software.
I would love to work on your project. Please send me more details.
Warm regards,
Sheela Kalawar
