Tracking Device

Tracking device is android based project. It is already developed but some issues or bugs will be need to solve. We want android developer for solve those issues. The issues are following. 1) If net is not active then data should be buffered in app and send later on. 2) If Gps is not on then location should be fetched using mobile network. 3) Data sould be consistently updated with server. 4) If app permission are not set then when started it should ask for permissions. 5) When speed is less than zero the update should not be done. update should be done based on distance or speed. 6) If wrong co-ordinates are being sent. mobile is present on one location but co-ordinates are given may be 30-200 km apart from current location. 7) Data should be sent in background as service.
