actually this question is totally the opposite to this one.
Can I use library that used android support with Androidx projects.
And I knew there has been a trick to handle the above question by this config
android.useAndroidX=true
android.enableJetifier=true
However, I'm not sure is there another trick for the opposite case. When an App uses a libs which depend on AndroidX, but at the same time, the App also has dependencies on Android-support libs.
The example dependencies
+--- App
| +--- com.android.support:support-compat:28.0.0
| +--- Lib#1
| | |
| | +--- androidx.appcompat:appcompat:1.0.2
Thank you :)
