Android needs to be able to determine if there is a captive portal on the network or if a network has Internet connectivity at all
|
|
To do so it polls a server on every connection and also periodically
|
|
This is a privacy issue.
|
|
|
|
There are multiple solutions:
|
|
- Use the default Google gen204 endpoint
|
|
- Google is not the most privacy friendly
|
|
- Disable the checks
|
|
- Would confuse users when behind a captive portal
|
|
+ Would potentially save a small amount of battery
|
|
- Use our own gen204 endpoint
|
|
- Not everyone will trust us (even if they're running our code)
|
|
- Randomly choose between many different endpoints
|
|
- We'd need permission
|
|
+ Would be the best
|
|
+ Would limit one actor from knowing all
|
|
- If a maintainer wants us to stop using theirs it'd take a while since not everyone updates instantly
|
|
- If a maintainer blocked it, it'd cause issues (no Internet symbol when there is)
