never used kotlin... do i have to enable it in my project in order to use this library or something? if so, please provide instructions as i have never used kotling (also would be nice if you could update the README)
Hi Or, Issue is still under check. Seems like a major issue (So thanks for that). As this library is written in Kotlin, you will have to enable it in you app also (Adding Kotlin to your app build.gradle and the kotlin plugin in project build.gradle) Once I will fix everything I will update the README file and you as well.
i dont understand, will adding kotlin to the my app fix the problem? when you say "once i will fix everything" you mean to make it work even if my app does not have kotlin?
Yesterday I did a quick example (fresh project and compile the library) and came to 2 conclusions:
- You must enable Kotlin in your app
- You must add constraint layout library also (adding implementation 'com.android.support.constraint:constraint-layout:1.0.2' to app build.gradle dependencies)
And it will work just fine.
The constraint layout thing is something that bothers me and im still checking it out.
So basically all you need to do is the following:
Project build.gradle file:
buildscript {
repositories {
google()
jcenter()
}
dependencies {
...
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.2.21"
}
}
App module build.gradle file
dependencies {
...
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.2.21"
implementation "com.github.udioshi85:libGenericSettings:1.4.1"
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
...
}
