No arm-linux-androideabi toolchain found in stripDebugDebugSymbols step

Question

Similar to this question, I get the same error but in a different place:

Execution failed for task ':app:stripDebugDebugSymbols'.
> No toolchains found in the NDK toolchains folder for ABI with prefix: arm-linux-androideabi

Various other answers suggest clearing build folders, uninstalling and reinstalling the NDK, etc. I've done that many times but still get this error.

The thing I don't understand is that is looking for an arm-linux-androideabi toolchain. The contents of my C:\Users\Tim\AppData\Local\Android\Sdk\ndk\23.0.7123448\toolchains\llvm\prebuilt\windows-x86_64\bin directory are:

As you can see, the only arm-linux-androideabi program is arm-linux-androideabi-as.exe which seems a bit weird. I even tried adding this to my app/build.gradle as suggested on this page.

        ndk {
            abiFilters 'arm64-v8a'
        }

Which I think means it should only build using the armv7a-linux-androideabi29 toolchain. arm-linux-androideabi isn't even mentioned on the list of target triples.

What is going on here?

Answer 1

I have no idea how the build process works, really, but I had the same error you did and fixed it by going to:

Tools\SDK Manager\Android SDK\

Then uncheck "Hide obsolete packages"

Then (hopefully) you see this conspicuous item at the the end of the list:

(this is a screenshot AFTER I uninstalled it)

If you uncheck it and apply, that's what worked for me.

I'm guessing the latest NDK update had a bug and this effectively reverses the latest update. What do you think? Talk amongst yourselves. Coffee talk.

Answer 2

According to this comment in the flutter repository issues you need to select a < 20 NDK version.
