i am getting gradle build error after update android studio in 3.6.1,please help how to resolved

This usually happens when something goes wrong in Android Studio's first launch (eg. system crash, connection loss or whatever).

Automatically

To resolve this issue close Android Studio and delete the following directory's content, necessary files will be downloaded on IDE's next launch.

Windows: C:\Users\your-username.gradle\wrapper\dists

And then restart you android studio so android studio downloaded it automatically.

OR

You can also download it manually and add it i to your android studio

Manually

1) Manually download Gradle 6.2.2 binary (direct link: https://services.gradle.org/distributions/gradle-6.2.2-bin.zip)

2) Open your android studio root directory, and extract the zip to the gradle folde

3) Open Android Studio, go to File->Settings->Build, Exectution, Deployment->Gradle and set "Gradle home" to point your new gradle-6.2.2 folder.

4) Sync and you are ready to go!

But i will recomend you to do not use manually ,letting Android Studio itself to do it.

Thanks

Have you tried removing /youruserhome/.Gradle ?

try invalidate cache and restart.

Go to File >> Invalidate cache / Restart >> again Invalidate cache / Restart (in the pop-up)

I too had multiple problems related to Android Studio upgrade to 3.6.1. tried many workarounds and fixes but none of them worked for me, so I downgraded my Android Studio to last stable version viz Android Studio 3.5.3

first of check your current working project android Gradle plugin version and Gradle version Go to File >> Project stretcher (in the pop-up) to change project android Gradle plugin version and Gradle version to same as current project
