check internet access without g oogle


  • if i’m correct, davdroid/dav5x relies on the built feature of android to check if a device has internet access, unfortunately this built in android feature sends a lot of metadata to the company that developped android, just to be clear, metadata that isn’t needed for checking if the phone has internet access…

    while i think people one major raeson why people use dav5x is the get away from this company, or have some form of control, privacy

    so, from a this point of view it seems more logical not to rely on the built in android feature, but have dav5x check the internet access it self.

    This might also be the reason why some people on this forum have problems with the synchronisation, namely dav5x thinking its offline, while it isn’t, because some built in tracking features are (un)knowingly blocked by the user…

    Hi,

    @steve said in check internet access without g oogle:

    sends a lot of metadata

    Just to be sure: Which metadata do you mean? It’s a /generate_204 request without any cookies, data etc.

    metadata that isn’t needed for checking if the phone has internet access…

    How should such a check work else? It must connect somehow to check whether it has connectivity, and then the endpoint which is connected to has the metadata (source IP / date+time).

    You can also set a custom URL: https://forums.bitfire.at/topic/1935/using-own-captive-portal-generate_204-instead-of-google-settings as a workaround if you have root access.

    i don’t have the info anymore, but it should be retrievable

    that is helpful, but unfortunately only for savvy owners of a rooted phone
