java - activeNetworkInfo 的 Getter 已弃用，在 Java 中已弃用

Question

activeNetworkInfo 的 Getter 已弃用，在 Java 中已弃用。如何解决这个问题？

我使用了下面的代码，但 android studio 告诉我“activeNetworkInfo”已被弃用。

应用 list :

minSdkVersion 21
targetSdkVersion 29

@Provides
    @Singleton
    fun provideIsNetworkAvailable(application: Application): Boolean {
        var isConnected = false
        val connectivityManager = application.getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            val networkCapabilities = connectivityManager.activeNetwork ?: return false
            val actNw = connectivityManager.getNetworkCapabilities(networkCapabilities) ?: return false
            isConnected = when {
                actNw.hasTransport(NetworkCapabilities.TRANSPORT_WIFI) -> true
                actNw.hasTransport(NetworkCapabilities.TRANSPORT_CELLULAR) -> true
                actNw.hasTransport(NetworkCapabilities.TRANSPORT_ETHERNET) -> true
                else -> false
            }
        } else {
            connectivityManager.run {
                connectivityManager.activeNetworkInfo?.run {
                    isConnected = when (type) {
                        ConnectivityManager.TYPE_WIFI -> true
                        ConnectivityManager.TYPE_MOBILE -> true
                        ConnectivityManager.TYPE_ETHERNET -> true
                        else -> false
                    }
                }
            }
        }
        return isConnected
    }

我正在使用此代码:

private fun isInternetAvailable(context: Context): Boolean {
        var result = false
        val connectivityManager =
            context.getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            val networkCapabilities = connectivityManager.activeNetwork ?: return false
            val actNw =
                connectivityManager.getNetworkCapabilities(networkCapabilities) ?: return false
            result = when {
                actNw.hasTransport(NetworkCapabilities.TRANSPORT_WIFI) -> true
                actNw.hasTransport(NetworkCapabilities.TRANSPORT_CELLULAR) -> true
                actNw.hasTransport(NetworkCapabilities.TRANSPORT_ETHERNET) -> true
                else -> false
            }
        } else {
            connectivityManager.run {
                connectivityManager.activeNetworkInfo?.run {
                    result = when (type) {
                        ConnectivityManager.TYPE_WIFI -> true
                        ConnectivityManager.TYPE_MOBILE -> true
                        ConnectivityManager.TYPE_ETHERNET -> true
                        else -> false
                    }

                }
            }
        }

        return result
    }
