Dagger and Butterknife

Question

I am using dagger2 in my app. But when I started project my activities was extended support AppcompatActivity.Now while build I am getting warning via butterknife.

API 'variantOutput.getProcessResources()' is obsolete and has been replaced with 'variantOutput.getProcessResourcesProvider()'.

To fix this I must upgrade butterknife version from 9.0.0-rc1 to 10.2.0 when I change version butterknife to 10.2.0 I am getting error to build.Because I am not using androidx. error like this:

Manifest merger failed : Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91 is also present at [androidx.core:core:1.0.0] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory). Suggestion: add 'tools:replace="android:appComponentFactory"' to element at AndroidManifest.xml:9:5-70:19 to override.

So I don't know how to fix this issue.If somebody had such kind of error and warning please help me if you fixed it

Migrate your project to AndroidX, butterknife 10.2.0 is on androidX.
