Check Internet

🌐 CheckInternetAndroid is a light library to check or observe internet connection in Android apps easily. It checks the real internet connection by connecting to the Google's DNS server. If call is successful, then the internet is working, else it is not working.

Setup

Add the maven library bucket to the dependencyResolutionManagement.repositories block in settings.gradle.kts file as follows:

dependencyResolutionManagement {
  ...
  repositories {
    ...
    maven("https://jitpack.io")
  }
}

Install the library to the project in desired module's build.gradle.kts file. Replace <current_version> with the actual version:

implementation("com.github.raheemadamboev:check-internet-android:<current_version>")

Implementation

Check internet connection (callback API):

CheckInternet(applicationContext).check { connected ->
  if (connected) { 
      // there is internet                
  } else { 
      // there is no internet                  
  }
}

Check internet connection (suspend API):

viewModelScope.launch {
  val connected = CheckInternet(applicationContext).check()
  if (connected) { 
      // there is internet                
  } else { 
      // there is no internet                  
  }
}

Observe internet status (StateFlow)

private val internet: CheckInternet by lazy { CheckInternet(applicationContext) }

override fun onResume() {
  super.onResume()
  internet.startObservingConnection()
}

override fun onPause() {
  super.onPause()
  internet.stopObservingConnection()
}

lifecycleScope.launch {
  internet.status.collectLatest { status ->
    when(status) {
      Initial -> {
        // initial state, internet is not being observed, should call startObservingConnection()
      }

      Connected -> {
        // there is internet
      }

      NotConnected -> {
        // there is no internet
      }
    }
  }
}
