I can't convert this method to RxJava3 despite having upgraded the dependencies

fun setSearchField(searchField: EditText) {
        searchDisposable = searchField.afterTextChangeEvents()
            .skipInitialValue()
            .debounce(400, TimeUnit.MILLISECONDS)
            .map { it.editable()?.toString() ?: "" }
            .distinctUntilChanged()
            .observeOn(AndroidSchedulers.mainThread())
            .subscribe(::onSearchQueryUpdated)
    }

Type mismatch. Required: io.reactivex.rxjava3.disposables.Disposable? Found: io.reactivex.disposables.Disposable!

    def retrofit_version = '2.9.0'
    implementation "io.reactivex.rxjava3:rxjava:3.0.4"
    implementation "io.reactivex.rxjava3:rxkotlin:3.0.0"
    implementation "io.reactivex.rxjava3:rxandroid:3.0.0"
    implementation "com.jakewharton.rxbinding3:rxbinding:3.1.0"
    implementation "com.squareup.retrofit2:retrofit:$retrofit_version"
    implementation "com.squareup.retrofit2:converter-gson:$retrofit_version"
    implementation "com.github.akarnokd:rxjava3-retrofit-adapter:3.0.0"
    implementation "com.squareup.okhttp3:logging-interceptor:4.7.2"

How should I accurately clean the project from RxJava2?

I tried Invalidate caches/Restart: nothing happened.

  • Examine the dependency graph, maybe there is a library or module that still has rx2 as transitive dependency. You can print this graph in the terminal with `./gradlew :app:dependencies`, or show them in the IDE (project structure). – Mister Smith Jun 08 '20 at 09:08
  • Nope, the command fails, and the IDE doesn't show any of that. – Kred Jun 08 '20 at 09:26

Dependencies: ./gradlew :dependencies

You see, that rxbinding3 has a transitive dependency to 

|    +--- io.reactivex.rxjava2:rxjava:2.2.10

Which overwrites RxJava3

Solution:

implementation 'com.jakewharton.rxbinding4:rxbinding:4.0.0'
