Gradle - Error Could not find method implementation() for arguments [com.android.support:appcompat-v7:26.0.0]

Question

I am trying to open existing android project in android studio and it gradle cannot build the app without the error

Error android studio keeps on throwing

Answer 1

I moved implementation to module-level build.gradle from root-level build.gradle. It solves the issue.

Answer 2

If implementation is not defined, you are writing on a wrong file. On Unity 2019+ the correct file is main template grandle and not some of the others.

Answer 3

Make sure you're adding these dependencies in android/app/build.gradle, not android/build.gradle

Answer 4

Replace implementation with compile.

compile was recently deprecated and replaced by implementation or api

Answer 5

Your Code

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')

Replace it By

dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
