I'm Trying to implement butterknife:9.0.0-rc2 with Dagger 2.19 and Jetifier = enable, but i get the next error:

The given artifact contains a string literal with a package reference 'android.support.v4.content' that cannot be safely rewritten. Libraries using reflection such as annotation processors need to be updated manually to add support for androidx.

How can solve this issue?

thanks for your kind help.

See #1395 (comment) for a workaround of this jetifier problem. No action to take on our side.

I get the same error , I migrated my existing project to androidx thats when i got this error, tried upgrading version to 10.2.0 and added compileOptions in build.gradle.
The findById is not recognized. Some workAround for this?? Thank you.

[rakeshbaral92]

Is there any solution yet. I have stuck after migrating my project to androidx.

[ldavidsp]

Change to these parameters in build.gradle, it worked for me using version butterknife:10.2.1

testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.1'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'

i am getting this error

[MohamedAboAdel]

I had exactly the same problem

I have made the following changes namely

implementation 'com.jakewharton:butterknife:9.0.0'
annotationProcessor 'com.jakewharton:butterknife-compiler:9.0.0'

to
implementation 'com.jakewharton:butterknife:10.2.1'
annotationProcessor 'com.jakewharton:butterknife-compiler:10.2.1'

[JR-Asif]

changing the version worked to 10.2.1 worked for me. Thankyou.
