debug version of react native Android app works, assembleRelease fails - react-native

Question

I'm able to build the debug version of my react-native app. However, when I try to build the release apk, I get the following error:
Execution failed for task ':blelibrary:verifyReleaseResources'.
java.util.concurrent.ExecutionException: com.android.builder.internal.aapt.v2.Aapt2Exception: Android resource
linking failed Output:
/Users/someguy/projects/third/someapp/android/blelibrary/build/intermediates/res/merged/release/values-v26/values-v26.xml:7:
error: resource android:attr/colorError not found.
followed by a ton of messages that look like this:

Answer 1

Add the following to the android build.gradle:
subprojects {
afterEvaluate {project ->
if (project.hasProperty("android")) {
android {
compileSdkVersion 28 // have to match with build.gradle and app/build.gradle ones
buildToolsVersion '28.0.3' // have to match with build.gradle and app/build.gradle ones
variantFilter { variant ->
def names = variant.flavors*.name
// To check for a certain build type, use variant.buildType.name == "<buildType>"
if (names.contains("reactNative51") || names.contains("reactNative55") || names.contains("reactNative56")) {
// Gradle ignores any variants that satisfy the conditions above.
setIgnore(true)
}
}
}
}
}
}
