Getting warning “NDK is missing a 'platforms” directory.' with no NDK [duplicate]

[marcialwushu]

I've got a project that only uses the Android SDK, not the NDK, but I'm getting warnings whenever I build with gradle about the NDK:

NDK is missing a "platforms" directory.
If you are using NDK, verify the ndk.dir is set to a valid NDK directory.  It is currently set to /usr/local/opt/android-sdk/ndk-bundle.
If you are not using NDK, unset the NDK variable from ANDROID_NDK_HOME or local.properties to remove this warning.

Seems like a pretty clear warning. I'm not using the ndk, so there is no ndk-bundle in my android-sdk. The issue is that I don't have an ANDROID_NDK_HOME set, and my local.properties file (which appears to be generated by Android Studio) doesn't set the NDK:

sdk.dir=/usr/local/opt/android-sdk

I do have an ANDROID_HOME environment variable:

ANDROID_HOME=/usr/local/opt/android-sdk

System is a mac, but we seem to get the same issue in Docker. Anyone know how to get rid of this warning?

Sounds like maybe updating SDK from Android Studio IDE could help

Steps are:

• 1 - Go to Tools (top-menu item) > Android > SDK Manager
• 2 - Click SDK Tools tab
• 3 - Scroll down to the NDK checkbox update-option

Just install the Android NDK.

That fixed my error and warning!

• 1 - Go to Tools -> Android -> SDK Manager
• 2 - Click SDK Tools
• 3 - CHECK NDK
• 4 - Apply and quit.
