You need not to worry   Just enable Jetifier in your projet    Update Android Studio to 3 2 0 or newer  Open gradle properties and add below two lines   android enableJetifier true android useAndroidX true    It will convert all support libraries of your dependency to AndroidX at run time  you may have compile time errors  but app will run

I added below two lines in gradle properties file android useAndroidX true android enableJetifier true  then I got the following error error  package android support v7 app does not exist import android support v7 app AlertDialog                                                        I have removed the imports and added below line import static android app AlertDialog     And the classes which are extended from AppCompactActivity  added the below line   For these errors you just need to press alt enter in android studio which will import the correct library for you  Like this you can resolve all the errors  import androidx appcompat app AppCompatActivity   In your xml file if you have used any  lt android support v7 widget Toolbar   replace it with androidx appcompat widget Toolbar then in your java code import androidx appcompat widget Toolbar

If your project is not AndroidX  mean Appcompat  and got this error  try to downgrade dependencies versions that triggers this error  in my case play-services-location   implementation  com google android gms play-services-location 17 0 0      I solved the problem by downgrading to com google android gms play-services-location 16 0 0

Manually adding android useAndroidX true and android enableJetifier true giving me hard time  Because it s throw some error or   Suggestion  add  tools replace  android appComponentFactory   to  lt application gt   To Enable Jet-fire in project there is option in android Studio  Select Your Project ---  Right Click  app----  Refactor ----  Migrate to AndroidX   Shown in below image -     After click on Migrate to AndroidX   It will ask for confirmation and back up for your project     And last step it will ask you for to do refactor     After doing Refactor check your gradle properties have android useAndroidX true and android enableJetifier true  If they are not then add these two lines to your gradle properties file   android useAndroidX true android enableJetifier true      Note - Upgrading using Android Studio  this option works if you have   android studio 3 2 and onward  Check this

API 29   usage AndroidX libraries  If you are using API 29    then you cannot remove these  If you want to remove AndroidX  then you need to remove the entire 29   API from your SDK      This will work fine

You can enable Jetifier on your project  which will basically exchange the Android Support Library dependencies in your project dependencies with AndroidX-ones   e g  Your Lottie dependencies will be changed from Support to AnroidX   From the Android Studio Documentation  https   developer android com studio preview features           The Android Gradle plugin provides the following global flags that you   can set in your gradle properties file          android useAndroidX  When set to true  this flag indicates that you want to start using AndroidX from now on  If the flag is absent    Android Studio behaves as if the flag were set to false    android enableJetifier  When set to true  this flag indicates that you want to have tool support  from the Android Gradle plugin  to   automatically convert existing third-party libraries as if they were   written for AndroidX  If the flag is absent  Android Studio behaves as   if the flag were set to false       Precondition for Jetifier    you have to use at least Android Studio 3 2   To enable jetifier  add those two lines to your gradle properties file   android useAndroidX true android enableJetifier true   Finally  please check the release notes of AndroidX  because jetifier has still some problems with some libraries  e g  Dagger Android   https   developer android com topic libraries support-library androidx-rn
