How To Call This Function From Other Activities?

i need help in this kotlin code pls ... i have checkConnctivvity() function and it's working perfectly ... fun checkConnectivity(){ val cm=getSystemService(Context.CONNECTIVI

Solution 1:

1. Create Kotlin file, e.g. named Utils;

2. Move function to that file, and add Context parameter:

   funcheckConnectivity(ctx: Context): Boolean {
       val cm = ctx.getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
       val activeNetwork =cm.activeNetworkInfo
       return activeNetwork != null && activeNetwork.isConnectedOrConnecting
   } 
   

   If you intend to use it only in Activity you can create extension function without Context parameter:

   fun Activity.checkConnectivity(): Boolean {
       val cm = getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
       val activeNetwork =cm.activeNetworkInfo
       return activeNetwork != null && activeNetwork.isConnectedOrConnecting
   }
   

3. Call that function from wherever you want. If you call it from Activity just use code:

   checkConnectivity(this@YourActivity)
   

   If you created extension function, just call it in Activity without passing any parameters:

   checkConnectivity()
