All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 27.1.1, 23.1.1.

I got this error when I add the library to gradle !

I used implementation 'com.miguelcatalan:materialsearchview:1.4.0'

Any idea to solve this problem? :)

I have the same problem

Guys, have tried upgrading the Gradle plugin?

[lmgy]

I added implementation 'com.android.support:support-v4:27.1.1' and implementation 'com.android.support:design:27.1.1' to build.gradle

Well simple and quick solution for android conflicting versions that can lead to runtime crashes is to add them manually

This is how you can add them.
