The path route of my ndk is "ndk.dir=/home/javier/Android/Sdk/ndk" Thanks for your help

Edit the local.properties file, and add the following line to it, under sdk.dir - ndk.dir=/path/to/your/Android/Sdk/ndk/21.3.6528147

and then delete or comment out the ndkVersion '21.3.6528147' line from the gradle file.

That should solve the issue. If you now get the CMake was unable to find a build program corresponding to "Ninja" error, uninstall cmake 3.10 and install cmake 3.6 instead.

Now everything should work fine, but just in case it still insists on the wrong cmake for some reason, you can also the following line to your local.properties file: cmake.dir=/path/to/your/Android/sdk/cmake/3.6.4111459
