A modern programming language that makes developers happier.

kotlinlang

Hi, i am trying to use `coroutines`  using ` 'androidx.lifecycle:lifecycle-extensions:2.2.0-alpha01'` which is latest version but i'm unable to get ```viewLifecycleOwner.lifecycleScope.launch {}//here lifecycleScope is not available``` , what i'm missing ?

the right package for this is
`androidx.lifecycle:lifecycle-runtime-ktx:2.2.0-alpha01`

and for livedata builders
`androidx.lifecycle:lifecycle-livedata-ktx:2.2.0-alpha01`

so can i remove 'extensions' and just keep 'runtime' and what is diffrence between both packages?

extensions it’s the package for LiveData/ViewModel which they extend the lifecycle objects (LifecycleOwner/Observer)

it’s not about kotlin extension functions

the `-ktx` are the ones with kotlin related code extensions

maybe there’s a `extensions-ktx` which has both?  I haven’t tried

in any case you can read more here
