Huawei Android SDK

Try our SDK in your Android application

1. Integrate dependencies

To integrate our SDK into your application edit your build.gradle:

• Add this block to the root section:

allprojects {
    repositories {
        //...
        maven {
            url "https://jitpack.io"
        }
    }
}

• Add this block to the dependencies section:

implementation 'com.github.FendAiCorp.fendvpn-android:sdk:<VERSION>'

2. Configurate SDK

To start using the SDK, you need to create a WireSdk instance. Initialize FendSDK with a WireConfig:

val sdk = WireSdk.provide(
    WireConfig("backend url", "project id", "app version")
)

Value	Description
backend URL	Base URL for the API calls (login, fetching locations, etc.)
project id	A unique identifier of the project
app version	The application version for analytics purposes

For backend URL and project ID please contact [e-mail]

3. Use API

After SDK initialization you need to authenticate the user on the backend and acquire the list of available locations to connect.

3.1 Authentication

sdk.api().login(WireAuth.AuthAnonymous).fold(
    onSuccess = {
        //success
    },
    onFailure = {
        //error
    }
)

sdk.api().logout() // logout the user
sdk.api().isLoggedIn() // check if user is logged in

3.2 Available locations

sdk.api().locations().fold(
    onSuccess = { locations ->
        // select location to connect to
    },
    onFailure = {
        // error
    }
)

4. Manage VPN

After getting a virtual location configuration, you are ready to start a VPN session.

4.1 Start / Stop

val location: VirtualLocation = //use location fetched 
                                // on the previous step
sdk.vpn().start(SessionConfig(location)).fold(onSuccess = {
    // connected
}, onFailure = {
    // connection error
})

sdk.vpn().stop() // to stop vpn session

4.2 Statistics

An active VPN connection provides statistics on the amount of traffic, connection start time, and the chosen VPN server IP.

val stats = sdk.vpn().stats()
stats.fold(
    onSuccess = {
        // update traffic data
    },
    onFailure = {
        // error
    }
)

4.3 State

The SDK can provide information on the current VPN tunnel state.

sdk.vpn().state().collect { state->
    // state updated
}

Value	Description
VpnState.IDLE	No active VPN connection exists
VpnState.CONNECTING	Establishing a VPN connection right now
VpnState.CONNECTED	A VPN connection is established and active
VpnState.ERROR	A VPN connection process has failed
