Unable to Build with Latest Android Studio and Kotlin (Duplicate Class)

[tohizma]

I'm using Android Studio 4.2.1 Build #AI-202.7660.26.42.7351085, built on May 11, 2021 Runtime version: 11.0.8+10-b944.6842174 amd64 VM: OpenJDK 64-Bit Server VM by N/A

Kotlin version 1.5.10 (also tried on 1.5.0)

Simple test Code:

override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        AndroidNetworking.initialize(applicationContext);

        sendToServer("1234")
    }

    private fun sendToServer(scannedCode: String) {

        AndroidNetworking.post("http://192.168.1.3/scanner")
            .addBodyParameter("c", "packinglist")
            .addBodyParameter("d", scannedCode)
            .setTag("scanverify")
            .setPriority(Priority.HIGH)
            .doNotCacheResponse()
            .build()
            .getAsJSONArray(object : JSONArrayRequestListener {
                override fun onResponse(response: JSONArray) {
                    // do anything with response
                    Log.e(TAG, response.toString())
                }

                override fun onError(error: ANError) {
                    // handle error
                }
            })
    }

There's nothing fancy in gradle scripts (except defaults from android studio) and in gradle app module:

implementation 'com.amitshekhar.android:android-networking:1.0.2'

[egasudrajat]

same here

[darkbox]

Add this to the gradle.properties:

android.useAndroidX=true
android.enableJetifier=true

For me it stops complaining

[tohizma]

android.useAndroidX=true

is already there by default

android.enableJetifier=true

Yes! that's solve the problem. Signs that Fast Android Networking library need to be modernized to androidX

Thank you
