Build log

MIPS architecture is not supported since NDK r17
You have to remove it from your configuration or install older NDK manually.

Hello @koral,
Thanks for reply, How can I remove from configuration or Install older ndk Manually ? can you please explain a bit

I did a migration/upgrade on one of our sample android projects for the Android NDK r18 update, here’s the PR what I had to do for this really simple sample project:

For installing an older NDK: How to install a specific Android NDK version on the Android/Linux stack

The simplest option is to just upgrade Android Gradle plugin as @viktorbenei linked:
You may also need to add google() repository to buildscript block if needed and upgrade Gradle wrapper if it is not compatible with desired AGP version:

At the time of writing the current version is 3.2.1 but minimal supporting NDK r17+ is AFAIR 3.1.0.
