Error: No toolchains found in the NDK toolchains folder for ABI with prefix: llvm

Question

I want to compile an open source android project (Netguard) using gradel (gradlew clean build) But I encountered this Error:

A problem occurred

I've had a similar problem, but I wanted to use NDK version r9d due to project requirements.

In local.properties the path was set to ndk.dir=C\:\\Android\\ndk\\android-ndk-r9d but that lead to the problem:

No toolchains found in the NDK toolchains folder for ABI with prefix: [toolchain-name]

The solution was to:

1. Install the newest NDK using sdk manager
2. Copy the missing toolchain [toolchain-name] from the new ndk to the old. In my case from sdk\ndk-bundle\toolchains to \ndk\android-ndk-r9d\toolchains
3. Repeat the process till all the required toolchains are there

It looks to me that the copied toolchains are not used, but for some reason it is needed to for them be there.
