Android 17 may block apps from reaching home servers
After updating a phone to Android 17, a custom stopped sending data to a local server. The connection did not show a clear reason and only ended in a timeout.
The cause was Android 17 putting access to behind a new permission. Locally resolved can be affected too.
For example, if example.com points to a device inside the home network, an app may fail unless it supports the new . App makers also need to handle the case where the user later removes that permission.
Key points
- Android 17 may require a new permission before apps can reach .
- that point to home-network devices can also be affected.
- Apps without the new may fail with only a timeout.
- s for a may need updates to keep working.
- Apps should also handle the user removing the permission later.
