6. be careful that if you add modules for safe args, then downgrade the Gradle version.
7. be attention to add on utf-8 encode tag on the top of your vectorized drawable, otherwise you got build error for String--toooooo-Loooooong ~
8. for Safe Args:
(1) at top level gradle
buildscript {
dependencies {
// 4.1.2 downgrade for safe-args to 3.6.4
classpath "com.android.tools.build:gradle:3.6.4"
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
// for safe-args
classpath 'com.google.gms:google-services:4.3.4'
// safe-args => 2.3.3
classpath "androidx.navigation:navigation-safe-args-gradle-plugin:$nav_version"
(2) at app level gradle
plugins {
id 'androidx.navigation.safeargs.kotlin'
}
