The application is not opening on startup using Default Library Setup

[DktPhl2019]

Hello!

I want to use AAChartCore-Kotlin library. I set up everything as described in the github page, but the app is not starting on the emulator open in Android Studio on Windows 10. Could you please review below and point me as why the app is not working. Thank You

settings.gradle:

pluginManagement {
    repositories {
        gradlePluginPortal()
        google()
        mavenCentral()
    }
}
dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
        maven {
            url "https://jitpack.io" }
    }
}
rootProject.name = "MyChartApp"
include ':app'

If the app is not starting, did you check the logcat output?

If the app is not starting, did you check the logcat output? The logcat has lot of information. Do you know what I should look at? Could you please reply. Thank You

Use dependency with version : implementation 'com.github.AAChartModel:AAChartCore-Kotlin:7.1.0'

and adjust the view, by adding :

        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
