Add androidx support for external library

Question

I migrated my Android project to androidX and now facing several issues with support for androidX. I was able to fix some of them with upgrading the external library to its latest version to support androidX. But I have other libraries that are not maintained for several years. For example I am using the KenBurnsView and get following error:

Unresolved reference. None of the following candidates is applicable because of receiver type mismatch: 
public val Activity.ivStoryItem: KenBurnsView! defined in kotlinx.android.synthetic.main.fragment_story_item
public val Dialog.ivStoryItem: KenBurnsView! defined in kotlinx.android.synthetic.main.fragment_story_item
public val android.app.Fragment.ivStoryItem: KenBurnsView! defined in kotlinx.android.synthetic.main.fragment_story_item
public val android.support.v4.app.Fragment.ivStoryItem: KenBurnsView! defined in kotlinx.android.synthetic.main.fragment_story_item
public val View.ivStoryItem: KenBurnsView! defined in kotlinx.android.synthetic.main.fragment_story_item.view

I already tried to exclude the support.v4. library in the KenBurnsView but it did not help. How can I fix this error?

Have you added these lines to gradle.properties: android.useAndroidX=true android.enableJetifier=true — Arslan Shoukat, Sep 04 '19 at 12:24
Like a variant you can download the source code of your library and migrate it to AndroidX. And after that add it to your app (like apk or android library) — Marat Zangiev, Sep 04 '19 at 12:26
@MaratZangiev so you mean the only solution is to fork each library and add support for androidX by myself? — rm -rf, Sep 04 '19 at 12:28
I think it is a good idea. Especially you say: "library is not maintained for several years". — Marat Zangiev, Sep 04 '19 at 12:35
oops, in above comment not "like apk or android library" but "like jar or android library" — Marat Zangiev, Sep 04 '19 at 12:38

You can try adding jetifier and androidx flags to gradle.properties file.

android.useAndroidX=true android.enableJetifier=true

Here you have the reason : https://stackoverflow.com/a/52034414/12009871
