androidkotlindeprecatednetworkinfo

NetworkInfo has been deprecated by API 29

I wanted to check the network connection. So, I used ConnectivityManager.activateNetworkInfo.isConnected

unfortunately, that's deprecated in API 29.

private fun isOnline(): Boolean {
    val connectivityManager = appContext.getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
    val networkInfo = connectivityManager.activeNetworkInfo
    return networkInfo != null && networkInfo.isConnected
}

and you can see depreciation message here

Solution

  • It's deprecated base on Google Document

    So, If you want to find the Network Connection status, you can use this code.

    kotlin :

     private fun isNetworkAvailable(context: Context): Boolean {
    val connectivityManager = context.getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        val nw      = connectivityManager.activeNetwork ?: return false
        val actNw = connectivityManager.getNetworkCapabilities(nw) ?: return false
        return when {
            actNw.hasTransport(NetworkCapabilities.TRANSPORT_WIFI) -> true
            actNw.hasTransport(NetworkCapabilities.TRANSPORT_CELLULAR) -> true
            //for other device how are able to connect with Ethernet
            actNw.hasTransport(NetworkCapabilities.TRANSPORT_ETHERNET) -> true
            //for check internet over Bluetooth
            actNw.hasTransport(NetworkCapabilities.TRANSPORT_BLUETOOTH) -> true
            else -> false
        }
    } else {
        return connectivityManager.activeNetworkInfo?.isConnected ?: false
    }
}

    Java :

    private Boolean isNetworkAvailable(Application application) {
    ConnectivityManager connectivityManager = (ConnectivityManager) application.getSystemService(Context.CONNECTIVITY_SERVICE);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        Network nw = connectivityManager.getActiveNetwork();
        if (nw == null) return false;
        NetworkCapabilities actNw = connectivityManager.getNetworkCapabilities(nw);
        return actNw != null && (actNw.hasTransport(NetworkCapabilities.TRANSPORT_WIFI) || actNw.hasTransport(NetworkCapabilities.TRANSPORT_CELLULAR) || actNw.hasTransport(NetworkCapabilities.TRANSPORT_ETHERNET) || actNw.hasTransport(NetworkCapabilities.TRANSPORT_BLUETOOTH));
    } else {
        NetworkInfo nwInfo = connectivityManager.getActiveNetworkInfo();
        return nwInfo != null && nwInfo.isConnected();
    }
}

    you can see all NetworkCapability here.
