I am developing the application in which I want to use VPN network. to create VPN network in device we need to configure it from (settings-wireless and network-VPN settings) menu of device.
I want to do this many settings via code with hard-coded information.
From API level 4.0 android provides API to handle the VPN services.
To know the implementation of this methods I used the Sample project of Android ToyVPN. But in this many methods I didn't find any method to pass username and password. information which I have to connect VPN network is.
VPN Server name
Username
Password
Using this three information I am successfully connecting to VPN network if I am configuring manually from device. But I want to do this programmatically. Here is the class file which is used to connect to VPN network. ToyVpnClient.java and ToyVpnService.java. in addition to this sample application is crashes in device.
Any help will be appreciated.
The VpnService you are talking about is not what you think. It's just a framework for you to create your own VPN solution. Once established, you'll get all communication on the network (IP) layer and you can do anything you want with it, e.g., encrypt it and send it to your server - the example for this is the ToyVpn project found in /samples/android-14/ directory. You also need a your own server side code to do the decryption and the necessary routing of the traffic.
Unfortunately you can't set the built-in android VPN programmatically. The best you can do is to show a dialog to the user explaining how to set it and then pop up the system settings with the correct screen showing.
It is possible using internal android.jar(com.android.internal) and hidden(#hide) API. Refer the below link:

I am currently creating a remote control app which uses IP control to control devices. I have created this and now I am looking to add a way for you to say for example, "OK Google, Power on 'device' in 'app name'". I have looked at Google's app actions console and I could not find a way to make this as a custom command. I have seen that there is a way to do this by adding deep links into my application. However everywhere I look this requires me to have a host web server which I do not want. Is there any way to do this without a web host or otherwise using the device as it's own host or it's own fulfillment server within the app?
The URL may or may not be resolvable by an HTTP client and it won't send a request to this links. Alternatively, you can also define a custom URL scheme. e.g. myapp://example/{foo}.

I need to connect a Vpn programmatically in my app, but can't seem to find a way. I see VpnService, StrongSwan, OpenVpn but this seems not IPSec. How do I go about connecting to my already build IPSec and L2TP servers that have a username, password and pre shared key.
You can not do it in the latest versions of Android. It could be done via SystemProperties.java class which has API available for these connections, but these API are now hidden in the latest Android versions due to Security risks.
However if the phone is rooted then you can use it via hacks like reflection etc to access those System properties and get everything going.
I'm trying to connect to a VPN, in order to have permissions to some web services that I request using HttpURLConnection. I need to enter the server and the credentials to the VPN, but I have no clue how to do that. I'm concerned that exists the vpnService but I didn't find how to use it and mainly how to pass credentials to it. Can you guys help me?
I want to establish the connection to a VPN from my university and, once did it, make the connections pass through it. I did it manually at the phone and It worked. Now I want to do it at the code so people that uses my app don't need to do that.
Edit: I just want to connect to a vpn programatically, instead of doing it through the vpn settings at android's settings menu.
I have created a VPN Profile on my Android device. Now, I would like to create an Android application to manage (restrict and allow) which applications can access this VPN Profile.
So far, I've looked at Android's VPN Service which allows us to manage which applications can access the VPN Service but I am unable to correlate how this solution fits in with an already created VPN Profile.
There is no relation betweeen the VpnService API and VPN connections you create in Android's built-in VPN client. When using the VpnService API you'll have to implement a VPN protocol yourself and tunnel data read from the TUN device, which is created via the API, and back again (or use a library that implements a VPN protocol that does this for you), only then can you restrict apps from using the VPN using VpnService.Builder's addDisallowedApplication() method.
You can also look for VPN apps in the app store that already use this API and support excluding (or including) apps that may use the VPN.
you can find many free vpn or proxy servers. I use nord vpn and his efficiency I check on whats my ip service. You can also use it. Its free. VPN is important where you need to get access to blocked sites or social media like twitter or Facebook. During my trip to China I used vpn and whats my ip service.
I am currently deploying an app to a company that requires using their proxy for outbound http[s] connections. The issue I'm running into is my all of my requests I wrote work fine because I can make them use a proxy, however I'm using the Parse library for handling push notifications. When the user logs into the app it needs to setup the push sub on parse but cannot due to the app trying to use direct http connection to api.parse.com.
Is there a way to force all of the app to use the system proxy settings?
Is there another push library/service that would better suit my needs if not?
Thanks!
