React Native Error while generating the main dex list

Question

I tried most the answers provided in stackoverflow as well as github from adding

multiDexEnabled true 
dexOptions{javaMaxHeapSize "4g"}

but there was no luck, I think my problem is with the dependencies. The actual error I am getting when I run cd android ./gradlew clean then gradlew assembldebug or react-native run-android is

What went wrong: Execution failed for task':app:transformClassesWithMultidexlistForDebug'. com.android.build.api.transform.TransformException: Error while generating the main dex list.

Building in Android Studio shows the following Error:

Program type already present: androidx.versionedparcelable.CustomVersionedParcelable

adding

android.useAndroidX=true
android.enableJetifier=true

causes more problems since most of my react-native libraries that I used in my project not translated to androidx

Execution failed for task ':react-native-navigation:compileReactNative57_5DebugJavaWithJavac'

so my intention is to draw back from androidx, is there a way to do so?

can you provide error log, and as you fail in assembldebug can you install that,bear in mind that using debug build in react will give users access ti devMenu — nima moradi, Jun 21 '19 at 16:02
no provide complete log, another good practice is using android studio which give more hint — nima moradi, Jun 21 '19 at 16:19

After a day of research, couldn't find a correct way to roll back from androidx and translating all react-native dependencies to androidx manually seems a tedious job but thanks to this library jetifier I was able to do so just by running

npm i --save-dev jetifier
npx jetify
