Google play doesn't update apps

[SG5]

In play market work all except update/install app.
It just shows message "searching network..."

yes, there is kind issue, i described it in readme:

Issues: Some apps do not recognize the reverse tethered internet connection due to ConnectivityManager policy. Just leave WiFi or 3g connection active, connection will go through SimpleRT anyway.

[Sur3]

Please reopen...
It seems Android just shows no activeNetwork because it wants a VPN to have an UnderlyingNetwork for that, and you can set the own Network as underlyingNetwork...
https://issuetracker.google.com/issues/37109422:
"can you use VpnService#setUnderlyingNetworks to solve this issue? Once the VPN is established, find the Network object of the VPN and then pass it to setUnderlyingNetworks."
"you can try setting your own network as the underlying network. getAllNetworks will return an array of networks, and you can inspect those to find out which one is your own (e.g., by calling getLinkProperties)"
Please fix that. Thanks.

[vvviperrr]

can you use VpnService#setUnderlyingNetworks to solve this issue

yes, its possible, but this stuff supported only in API>=22, when i want to have one apk build for all api's >=14. i need to research how to do that (i am more linux coder than android).

[Sur3]

i am more linux coder than android

I Know what you mean, me too. :D
But you could at least look if android.os.Build.VERSION.SDK_INT >= 22 and then set the Underlying Network and otherwise skip it. ^^"

[vvviperrr]

sure, i'll fix it asap

I tried the method suggested by Sur3 (Waiting for network to be connected, then calling setUnderlyingNetworks on the VPN builder object with the now connected network object. I also tried calling reportNetworkConnectivity for the network object, and still doesn't work. Browser and Google play still report no network. Here's some debug. Note the last line with "isDefaultNetwork-false". I'm wondering if a network of VPN can never be the default network...

At least it tries to set it as default network, some properties just seem not to be satisfied, probably because of the missing extension..

[thardie]

Any ideas what the missing extensions are? I'd love to get this fixed...

[thardie]

Looks like that ConnectivityExt is a red herring, and you can find a lot of other people mentioning it and seems unrelated.

What I did find doesn't bode well. That "would not satisfy default request" messages comes from this code:
// Don't bother validating networks that don't satisify the default request. // This includes: // - VPNs which can be considered explicitly desired by the user and the // user's desire trumps whether the network validates. // - Networks that don't provide internet access. It's unclear how to // validate such networks. // - Untrusted networks. It's unsafe to prompt the user to sign-in to // such networks and the user didn't express interest in connecting to // such networks (an app did) so the user may be unhappily surprised when // asked to sign-in to a network they didn't want to connect to in the // first place. Validation could be done to adjust the network scores // however these networks are app-requested and may not be intended for // general usage, in which case general validation may not be an accurate // measure of the network's quality. Only the app knows how to evaluate // the network so don't bother validating here. Furthermore sending HTTP // packets over the network may be undesirable, for example an extremely // expensive metered network, or unwanted leaking of the User Agent string. if (!mDefaultRequest.networkCapabilities.satisfiedByNetworkCapabilities( mNetworkAgentInfo.networkCapabilities)) { validationLog("Network would not satisfy default request, not validating"); transitionTo(mValidatedState); return HANDLED; }

The comment explicitly says VPN networks are excluded, and I've seen this capability flag that's on by default called "NOT_VPN". I think the system is hard coded not to ever consider a VPN as a default network.

[Sur3]

VPNs which can be considered explicitly desired by the user and the // user's desire trumps whether the network validates.
The question is then HOW can a user explicitly desire a VPN, probably there is an option somewhere, but I suppose the underlying network needs to be set anyway also for this user-based validation.
Probably we could also ask in the google ticket why it doesn't work.. https://issuetracker.google.com/issues/37109422

[thardie]

That's fine if you control your internet connection, but in my example, I put a google map up, and it uses the system's location services, which uses the system's default connection. Changing the App's connection still doesn't let the map load.

I'm to the point where for my specific application, I'm going to modify the base OS, so I can change the default network requirements.

Is there another way we could do this? IE, not use VPN for the connection, but instead RNDIS?

[Sur3]

Hi thardie.
I don't know what you mean by 'control my internet connection', you mean it is possible to set a specific connection for an app, how is that done?
And could you provide your apk and/or patch to set the underlying network, I'd like to try it myself.

[thardie]

By "control my connection", I meant in my app, I can make a call to set what type of network I want to be connected to. Then any sockets or communication I initiate from my app will use that connection. However, if I ask a system service for something, and it in turn needs to talk to the internet, it will use the system's connection, and not my app. Location services is one such example.

In terms of modifying the underlying network, I would have to modify the OS itself. I'd have to do this with cyanogenmod for example. I really would like to find another way.

I still don't have this working, so I don't have anything to give you yet. :(

[Sur3]

@vvviperrr any update on including that pr from eugene?

[robinpaulson]

@Sur3 @eugene-sevostianov-sc . Given that PR is a couple of years old now and apparently can't be merged, is either of you interested in fixing it up so it will work?

Thanks

[nanaceba]

@robinpaulson you can close it, #40 is merged with change from @Sur3 9b63526

[robinpaulson]

Thanks
