Can't build after updating to RN 56 - Execution failed for task ':react-native-material-kit:verifyReleaseResources'

[ds8k]

I'm unable to generate a release build after upgrading to React Native 56:

:react-native-material-kit:verifyReleaseResources/Users/user/.gradle/caches/transforms-1/files-1.1/appcompat-v7-26.1.0.aar/d966a29d4964b9817b018d8a3a1d16a4/res/values-v26/values-v26.xml:13:5-16:13: AAPT: No resource found that matches the given name: attr 'android:keyboardNavigationCluster'.
    
 FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':react-native-material-kit:verifyReleaseResources'.
> com.android.ide.common.process.ProcessException: Failed to execute aapt

Looks like compileSdkVersion and buildToolsVersion in build.gradle need to be updated. They're pointing to old versions right now:

compileSdkVersion 24
buildToolsVersion '23.0.3'

I managed to fix this by add below lines into project root's build.gradle that force subprojects to build using the same sdk:

subprojects {
    afterEvaluate {project ->
        if (project.hasProperty("android")) {
            android {
                compileSdkVersion 27
                buildToolsVersion "27.0.3"
            }
        }
    }
}

Replace version with yours.
