`wiish run --os android` fails

[UNIcodeX]

NOTE: I am able to build Android apps and run them on a physically tethered device and emulators using NativeScript on this machine, so my build deps should all be good to go.

Thanks for providing the log!

The solution, I think, is to install the Android NDK, as indicated by this in the logs:

...
NDK is missing a "toolchains" directory.
If you are using NDK, verify the ndk.dir is set to a valid NDK directory.  It is currently set to /home/jedi/Android/Sdk.
If you are not using NDK, unset the NDK variable from ANDROID_NDK_HOME or local.properties to remove this warning.
...

I'm trying to decide if wiish doctor should include these instructions or if it's fine to defer to what this log is showing.

@UNIcodeX Do you have the Android NDK installed? What does ls $ANDROID_NDK_HOME show?

[UNIcodeX]

Yes, sir. It is installed, however there may be an issue with architecture??

Would it perhaps require android-ndk64 instead?

[UNIcodeX]

It should be mentioned that I have both the Arch linux android-ndk and the android-studio packages installed. I had originally set ANDROID_HOME to /opt/android-sdk, but ended up having to switch it to ~/Android/Sdk.

NOTE: The platforms directory is under that ~/Android/Sdk directory as well.

I'm not smart enough with Android development to know if it's an architecture problem. Wiish is currently set up to build the an apk for 4 architectures, but I don't remember if it requires the NDK/SDK to be for a specific architecture.

Here's what I have on my macOS machine:

Do you have an ndk-bundle directory in $ANDROID_HOME? The error is specifically looking for a toolchains directory. Does find $ANDROID_HOME -name toolchains find anything promising? If so, maybe try setting ANDROID_NDK_HOME to the directory containing toolchains.

Once we've figured out what's wrong, I'd love to add something to wiish doctor that might aid the next person who encounters this error.

[UNIcodeX]

I don't currently have the ANDROID_NDK_HOME explicitly exported in my .zshrc, but it's pointing to the same location as ANDROID_HOME. ANDROID_SDK_ROOT also points to the same place.

ANDROID_HOME = ANDROID_SDK_ROOT = ~/Android/Sdk

The contents of that directory are:

[UNIcodeX]

The distro's android-ndk package installs to /opt/android-ndk and contains a toolchains folder, but when I set ANDROID_NDK_HOME to that directory and try to build, gradle complains that the directory does not contain a platforms directory...

The platforms were installed to ~/Android/Sdk by the Android Studio wizard.

[iffy]

@UNIcodeX If you symlink the ndk into the sdk directory so that they're kind of together like on my computer (and set the appropriate ANDROID_ environment variables) does it work?

Sorry to leave you hanging for a month.
