Android Studio 3.6.1 with Gradle Plugin Version 3.6.1 and Gradle Version 5.6.4 not working

Question

My application is working very well. I have just updated Android Studio 3.6.1,

After updating Android Studio I got this dialog and I am going to upda

Answer 1

I have tried many ways to solve this problem as follow:

1st solution: I have tried the solution of Mayur Sojitra and it worked for one day. (Next day I got the same problem again.)

2nd solution: I have tried to revert back with a lower version of Gradle that is 3.5.0 and It's working but I wanted to use the latest version only. (Way to find a new solution)

3rd solution: I am using firebase dependencies and I thought that error is coming because of Firebase version conflicts with Gradle so I have updated all the firebase repository. (May this is also working for you)

4th solution: I have used ObjectBox library so updated that version to the latest 2.5.1.

5th solution: Finally I caught the problem that My Internet Connection is restricted (as per company rules) and My Gradle and other dependencies are not downloading successfully so I thought updating all dependencies and download it successfully will be the solution for this weird question.

Do let me know If you have any questions or still get a problem.

Thank you.

Answer 2

Possible solution:

Upgrade the version of plugins in Top-level build.gradle.

Detail:

I upgraded the Gradle version from 5.4.1 to 5.6.4, and the plugin version from 3.5.3 to 3.6.2, and then I encountered a problem that the class could not find.

I have used Realm in the project and the top-level build.gradle is:

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    /.../
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.6.2'
        classpath "io.realm:realm-gradle-plugin:5.8.0"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

This problem seems like some library/plugin does not process R classes in R.jar but in R.java after the Gradle plugin version greater than 3.6.0. See here for detail.

And the solution is to upgrade Realm to a newer version, for me is 6.0.2. See here for detail.

    dependencies {
        classpath 'com.android.tools.build:gradle:3.6.2'
        classpath "io.realm:realm-gradle-plugin:6.0.2" // <- modify
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
