Jetpack is a box of libraries that help developers to follow best practises in coding, and reduce boilerplate code. These libraries are available in Google Maven repository
Many jetpack libraries provide Android KTX extensions as shown below.
dependencies {
def lifecycle_version = “2.2.0”
implementation “androidx.lifecycle:lifecycle-livedata-ktx:$lifecycle_version”
implementation “androidx.lifecycle:lifecycle-viewmodel-ktx:$lifecycle_version”
…
}
