UnifiedSDK.update() NoSuchMethodError

[Nevaehy]

Got this error on some real devices (API 24, 28, 30) and some AVD (API 22, 19)

java.lang.NoSuchMethodError: No static method update(Lcom/anchorfree/sdk/NotificationConfig;)V in class Lcom/anchorfree/sdk/UnifiedSDK; or its super classes (declaration of 'com.anchorfree.sdk.UnifiedSDK' appears in /data/app/com.blazing.fast.vpn-1/base.apk)

[Nevaehy]

The code is:

private fun initHydraSdk() {
        val notificationConfig = NotificationConfig.newBuilder()
                .disabled()
                .build()
        UnifiedSDK.update(notificationConfig)                                        <-- Error occurs there

        val clientInfo = ClientInfo.newBuilder()
            .baseUrl(resources.getString(R.string.host_url_key))
            .carrierId(resources.getString(R.string.carrier_id_key))
            .build()
        val transportConfigList: MutableList<TransportConfig> = ArrayList()
        transportConfigList.add(HydraTransportConfig.create())
        transportConfigList.add(OpenVpnTransportConfig.tcp())
        transportConfigList.add(OpenVpnTransportConfig.udp())
        UnifiedSDK.update(transportConfigList, CompletableCallback.EMPTY)
        val config = UnifiedSDKConfig.newBuilder().idfaEnabled(false).build()
        UnifiedSDK.getInstance(clientInfo, config)
        UnifiedSDK.setLoggingLevel(Log.VERBOSE)
        UnifiedSDK.addVpnStateListener(this)
}

Any ideas what could be the source of the problem?

[timoshenkoav]

no idea, method is there. Maybe its due to kotlin issue to call static methods on java interfaces. Try to add kotlinOptions { jvmTarget = '1.8' }

This code is already present. On other devices and APIs everything works as intended.

[timoshenkoav]

we've checked the sdk on devices with api levels you've mentioned. no issue exits. Maybe you have some custom proguard settings?

Proguard is empty. Also I tried settings that you specified in Readme. Had the same outcome.

[timoshenkoav]

from where do you have this stacktrace? just in logs? or in some crash logging system like firebase?

[Nevaehy]

Just in logs when I'm trying to launch app on AVD in Android Studio

[timoshenkoav]

ah, you can just skip it. it's just system logs, it still should work

[Nevaehy]

No, it doesn't. App crashes.

[Nevaehy]

[Nevaehy]

@timoshenkoav could you please reopen issue?

[Nevaehy]

At first, I've created an app that uses your SDK. Everything worked fine. Then, I've created a module (.aar) from this app and implemented it in absolutely clean, new project. And in this new project I've got this error on specified above devices.

[timoshenkoav]

just tried the app from this repo on AVD 22 - no crashes. Please check your app settings - dont think its sdk issue

[timoshenkoav]

if you made a lib check if you have runtime dependencies specified

[Nevaehy]

if you made a lib check if you have runtime dependencies specified

other APIs work fine, then all lib dependencies are fine too?

[timoshenkoav]

UnifiedSDK.update(notificationConfig) is the first api you call. what api do you call before?

[timoshenkoav]

try to build and run the app from this repo on the same device/avd

[Nevaehy]

UnifiedSDK.update(notificationConfig) is the first api you call. what api do you call before?

Nothing. I've tried .init() and others, but any api call results in crash and the same stacktrace error

[timoshenkoav]

so i suggest its dependency error. how do you specify the sdk dependency in aar library module? as 'implementation'? try the 'api'

[Nevaehy]

implementation 'com.github.AnchorFreePartner.hydra-sdk-android:sdk:3.3.3'
implementation 'com.github.AnchorFreePartner.hydra-sdk-android:openvpn:3.3.3'

[timoshenkoav]

try to change implementation to api

[Nevaehy]

try to change implementation to api

Just tried. Nothing has changed :(

[timoshenkoav]

hard to tell, try to build the app from this repo and run on the same avd/device - it should work

[Nevaehy]

Yep, I also tried it. It worked as a separate app, but not as an implemented module.

[timoshenkoav]

so you implemented it wrong

[timoshenkoav]

can you share your complete project sources that reproduce the issue?

[Nevaehy]

may I send link to repo via email?

[timoshenkoav]

sure - a.timoshenko@anchorfree.com

[Nevaehy]

sure - a.timoshenko@anchorfree.com

Great, thanks! Just sent you a message.

[timoshenkoav]

Do you have a requirement to make it as aar? Why not just do a library module in app module and add it as dependency

[Nevaehy]

yep, it's a requirement

[timoshenkoav]

ok, move vpn.aar to app/libs folder and add implementation fileTree(dir: 'libs', include: ['*.aar']) to app build.gradle

[Nevaehy]

Now I cannot go to VPNMainActivity because it's as unresolved reference now

[timoshenkoav]

you did something wrong

[timoshenkoav]

i'm sending working project to you

[Nevaehy]

Should I keep this?

1. include ':vpn' in settings.gradle
2. vpn folder with .aar and .gradle file inside the project

[timoshenkoav]

1. no, you can remove it 2.no, you can remove it

[Nevaehy]

I removed both and now it's unresolved reference for VPNMainActivity.. :)

[timoshenkoav]

check your email

[Nevaehy]

It works now, thank you!

But may I know the reason? Why didn't implementation project() work?

[timoshenkoav]

not sure, maybe its something with classloader

[abkoradiya]

@timoshenkoav I am getting this error when build aar file and use it. What is the solution?
