android.permission.WRITE_SECURE_SETTINGS error
WRITE_SECURE_SETTINGS is a signatureOrSystem permission, meaning that ordinary SDK applications cannot hold it. Only apps that are related to the firmware can hold this permission.
Reading all answers for this particular issue, one way around for this is to use this code to enable the gps but it wont work, as CommonsWare pointed, the application has to be system app for getting this code to work..so one can convert the application into system app by using TitaniumBackup. THis is working perfectly fine for me now.
*Sony users will see another message "Will collect anonymous data while using gps" - to overcome this, 'Freeze' the "LEarning Client" app and everything will be fine.
