Error after including KTX in Android project

[tneginareb]

java.lang.NoSuchMethodError: No static method getFont(Landroid/content/Context;ILandroid/util/TypedValue;ILandroid/widget/TextView;)

After I implemented KTX in build.gradle, after build process, this error occurred.

1. Are you using KTX for Gradle build scripting or in your application?
2. Did that error occur right after including an extra dependency or did some KTX code triggered it?
3. Does your application work with pure LibGDX?
4. Which KTX modules are you using?

Please include your build.gradle files or the whole project. Also, add whole stack traces in issues. You can run Gradle with --stacktrace.

Hey @czyzby , initially thank you for the quick response.

1. In my Application
2. An error occurred after including KTX, I didn't use any KTX code. I just add the dependency. (I added dagger dependency but I don't think that this dependency can have any mutual issue?)
3. Nope
4. I didn't have a chance to build the project initially.

my build.gradle:

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
apply plugin: 'kotlin-kapt'

android {

This is not our library. You wanted to be here.

[tneginareb]

@czyzby yes you're right. My mistake, sorry for that!

[czyzby]

It's OK, don't worry - I expected such issues since Google released their library with a similar name. Bookmark us, and give LibKTX a try if you ever wanted to develop some 2D games, though. ;)
