@iamareebjamal Koin module is not refreshing, event after opening the app again.

See how it is done in Orga App

In orga app, URL is directly set in Interceptor but here we are using koin module for retrofit build. I have tried to set URL in request builder, but not working.

[liveHarshit]

val preference = Preference()
    var url = preference.getString(API_URL)

    override fun intercept(chain: Interceptor.Chain): Response {
        val authorization = authHolder.getAuthorization()
        val request = chain.request().newBuilder()
        val httpUrl = url
        if (httpUrl != null) {
            request.url(httpUrl)
        }
        return if (authorization != null) {
            request.header("Authorization", authorization)
            chain.proceed(request.build())
        } else
            chain.proceed(request.build())
    }

We are using dagger there, so no difference. You have to implement it similarly, using Interceptor

Updated. Working 👍

This has a flaw which is in Orga App as well. This will replace every URL with API URL. We want only the API URL to be replaced

[liveHarshit]

I find this same solution: https://gist.github.com/swankjesse/8571a8207a5815cca1fb#file-hostselectioninterceptor-java-L19
One guy commenting that it will change all URLs: https://gist.github.com/swankjesse/8571a8207a5815cca1fb#gistcomment-2160202 and provide following solution for setting multiple API URLs using RetrofitUrlManager.getInstance().putDomain() : https://github.com/JessYanCoding/RetrofitUrlManager/blob/master/app/src/main/java/me/jessyan/retrofiturlmanager/demo/MainActivity.java
Can you please check it.

You just have to add an if statement, if (BuildConfig.API_URL == incomingUrl)
proceed to change, else skip

[liveHarshit]

How? BuildConfig.API_URL is always the default URL, and incomingUrl will change according to user preference. If they are equal then no need to change. I think it should reverse.

[iamareebjamal]

BuildConfig.API_URL will be the base URL. So incoming URL will be BuildConfig.API_URL if it is API call. In which case, we'll replace it with the URL in preference. If it is not BuildConfig.API_URL, then it may be for different domain, like google.com, in which case, we'll not replace it because it is not our API domain. Clear?

Yes ✌️
