[FIXED] Trying to use koin but doesnt work correctly on android

Issue

I'm trying to implement Koin in my project. So far, I did this:

My shared preferences class:

class MPCUtilSharedPreference(private val sharedPreferences: SharedPreferences{}

I want to inject that class in other classes. So, I create my MainApplication class:

class MPCMainApplication : Application() {

override fun onCreate() {
    super.onCreate()
    startKoin {
        androidContext(this@MPCMainApplication)
        modules(modules)
    }
}

}

This is my module class:

private val appModule = module {
single {
    MPCUtilSharedPreference(
        androidContext().getSharedPreferences(
            BuildConfig.APP_PREFERENCE,
            Context.MODE_PRIVATE
        )
    )
  }
}
val modules = listOf(appModule)

And the I'm trying to inject it:

class MPCNetworkInterceptor : Interceptor {

private val utilSharedPreferences: MPCUtilSharedPreference by inject() }

The error says:

No value passed for parameter 'clazz'

I'm trying to use

import org.koin.android.ext.koin.androidContext

But the AS uses

import org.koin.java.KoinJavaComponent.inject

This is my gradle:

implementation 'org.koin:koin-android:2.1.5'
implementation 'org.koin:koin-androidx-scope:2.1.5'
implementation 'org.koin:koin-androidx-viewmodel:2.1.5'
implementation 'org.koin:koin-androidx-fragment:2.1.5'

Any idea about what's the problem here?

Solution

You're trying to use by inject() delegate from an place that is neither an Activity nor Fragment, that's why the IDE is importing :

import org.koin.java.KoinJavaComponent.inject

If you want to use MPCUtilSharedPreference from MPCNetworkInterceptor, you can pass it as parameter in MPCNetworkInterceptor constructor. And obviously, add this in your module.

Otherwise, you could implement KoinComponent
