Android indoor navigation app

The project requirements is as below: 1. It is a indoor navigation software which applies the QR code and smartphone inner sensors (ex, compass sensor, accelerometer sensor) 2. The coordinate of the indoor plan map will be stored in the QR codes. Once you scan the QR code, it should display the personal location on the map. 3. When type in the destination information such as store name, office number or person's name, it should be displayed on the map. 4. With the help of the compass and accelerometer sensors, the app can trace the move until reaching the destination. We can talk about the details if you are interested. Thanks.
