If you migrated you wouldn't have anything like `com.android.support:appcompat-v7:29.0.1`. You would have something like `androidx.appcompat:appcompat:1.0.0` – user2836202 Aug 08 '19 at 12:32

Following artifacts don't exist:

implementation 'com.android.support:appcompat-v7:29.0.1'
implementation 'com.android.support:design:29.0.1'
implementation 'com.android.support:cardview-v7:29.0.1'
implementation 'com.android.support:palette-v7:29.0.1'
implementation 'com.android.support:recyclerview-v7:29.0.1'

Last support library version is 28.0.0 as you can see here:

Update the compileSdkVersion and buildToolsVersion to API 29 but keep the support library at version 28.0.0.

However, as you can see, support library is now frozen at version 28. So, it is somehow deprecated. So, another option is to migrate your project to AndroidX. It is basically the support library with a new name (putting in very simple words).

I have migrated to androidX. Can u let me know what are the latest versions are preferrable for the projectSupportLibraryVersion, projectMinSdkVersion, projectSdkVersion, projectBuildToolsVersion — sejn, Sep 08 '20 at 14:00
