- Posting it as Screenshot does not help at all.
- As written in #15 you have to parse them all by yourself to get the informations in them.

As I wrote above if you can set up GPS Connector as a mock location provider you don't need to parse them.

How i can set mock location by code

 

[agraham]

You can't. You must enable mock location in Developer Options, select your provider app, GPS Connect, and apps that use GPS should now be using the external GPS and not the internal one.

How i can solve this issue?
