android - NDK is missing a "platforms" directory. while trying to build

Question

Executing tasks: [clean]

Configuration on demand is an incubating feature. 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 /Users/ishandutta2007/Library/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.

Configuration 'compile' in project ':app' is deprecated. Use 'implementation' instead.

FAILURE: Build failed with an exception.

• What went wrong: A problem occurred configuring project ':app'.

  java.lang.NullPointerException (no error message)

Answer 1

This probably happens because Android Studio will automatically download the latest version of NDK which doesn't have a platforms directory (No idea why! Would be awesome if someone can clarify that).

This is what worked for me. Using the SDK manager. That is the icon in the top right corner of Android Studio that looks like this . Go to SDK Tools tab. In the right bottom corner, enable Show Package Details and install NDK version 20.0.5594570 (You can remove the newer version that was installed automatically by Android Studio to save space).

Note that the NDK will be installed in the location shown in Android SDK Location. For me that is set to /home/<username>/.local/android-sdk. Which means I can find the NDK at /home/<username>/.local/android-sdk/ndk/20.0.5594570/

Hit apply and when it's done go to file called local.properties and add this.

ndk.dir=/home/<username>/.local/android-sdk/ndk/20.0.5594570

Adapt the path to where you have your NDK installed.
