WiFi Prioritizer

***NOTICE: Newer Android Versions Support***
Please note that the app no longer functions correctly on Android 10 or higher. This is mainly due to the limits put on background scanning and applications' inability to force the OS network connection.
***END OF NOTICE***

WiFi Prioritizer aims to solve a simple problem by attempting to automatically reconnect to a higher priority wireless network when it comes in range while still being connected to a lower priority wireless network.

Simply drag the networks in the desired sequence and the app will take care of the rest. The default values are pulled from what's set in the system WifiManager. Android will honour those priorities only when it's establishing a fresh WiFi connection. So to help the system WiFi Prioritizer will also update those priorities (if the option is enabled) when you re-order the networks.

I wrote this application for my personal use but figured that if I have this problem, then surely there are other people out there with the same problem.

***NOTICE***
With Android 6.0 it seems the permission to access available access points was included in the location permission group. With version 2.0.6+ I needed add the ACCESS_COARSE_LOCATION permission for the application to work.

NB. Make sure your WIFI sleep policy is set to ALWAYS (Under WIFI settings -> Advanced settings) to avoid unnecessary connect/reconnect when the "Enabling WIFI at start of refresh" option is enabled.
