最近把项目升级到Android Q了，发现不少api都已经被Google标注为@Deprecated了，于是对部分API进行了适配。

适配完的方法每次在编译打包时依然还会报警告：
警告: [deprecation] ConnectivityManager中的TYPE_WIFI已过时
这个时候可以在app/build.gradle中设置：
android {
lintOptions {
checkReleaseBuilds false
abortOnError false
}
}
下次再编译就不会出现之前优化过的那些提示了，目前我是这样搞的，如有不对欢迎指正。

一、网络状态

指示网络的连接方式包括如下状态：
*TRANSPORT_CELLULAR(蜂窝网络) & TRANSPORT_WIFI & TRANSPORT_BLUETOOTH & TRANSPORT_ETHERNET & TRANSPORT_VPN & TRANSPORT_WIFI_AWARE & TRANSPORT_LOWPAN
*过时API:NetworkInfo类，全文方法阵亡

1.对手机当前是否连接网络进行优化

    /**
     * 当前是否连接网络
     */
    fun isNetworkConnected(): Boolean {
        val connectivityManager =
            this.getSystemService(Context.CONNECTIVITY_SERVICE) as? ConnectivityManager
        return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
            val networkCapabilities: NetworkCapabilities? =
                connectivityManager?.getNetworkCapabilities(connectivityManager.activeNetwork)
            if (networkCapabilities != null) {
                networkCapabilities.hasCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET)
                        && networkCapabilities.hasCapability(NetworkCapabilities.NET_CAPABILITY_VALIDATED)
            } else {
                false
            }
        } else {
            val networkInfo = connectivityManager?.activeNetworkInfo as NetworkInfo
            networkInfo.isConnected && networkInfo.isAvailable
        }
    }

2.当前使用的是蜂窝网络还是WIFI等相关方法进行了优化（Bluetooth等可自行修改）

   /**
     * 当前使用WIFI连接网络
     */
    fun currentNetWorkStatusIsWifi(): Boolean {
        val systemService =
            this.getSystemService(Context.CONNECTIVITY_SERVICE) as? ConnectivityManager
        return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
            val networkCapabilities: NetworkCapabilities? =
                systemService?.getNetworkCapabilities(systemService.activeNetwork)
            if (networkCapabilities != null) {
                networkCapabilities.hasCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET) &&
                        networkCapabilities.hasCapability(NetworkCapabilities.NET_CAPABILITY_VALIDATED) &&
                        networkCapabilities.hasTransport(NetworkCapabilities.TRANSPORT_WIFI)
            } else {
                false
            }
        } else {
            val networkInfo = systemService?.activeNetworkInfo as NetworkInfo
            networkInfo.isConnected && networkInfo.type == ConnectivityManager.TYPE_WIFI
        }
    }

    /**
     * 当前使用蜂窝网络连接网络
     */
    fun currentNetWorkStatusIsCelluLar(): Boolean {
        val connectivityManager =
            this.getSystemService(Context.CONNECTIVITY_SERVICE) as? ConnectivityManager
        return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
            val networkCapabilities: NetworkCapabilities? =
                connectivityManager?.getNetworkCapabilities(connectivityManager.activeNetwork)
            if (networkCapabilities != null) {
                networkCapabilities.hasCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET)
                        && networkCapabilities.hasCapability(NetworkCapabilities.NET_CAPABILITY_VALIDATED)
                        && networkCapabilities.hasTransport(NetworkCapabilities.TRANSPORT_CELLULAR)
            } else {
                false
            }
        } else {
            val networkInfo = connectivityManager?.activeNetworkInfo as NetworkInfo
            networkInfo.isConnected && networkInfo.type == ConnectivityManager.TYPE_MOBILE
        }
    }

最近事儿太多，等手上事情忙完了再更新哈，先给个美女图你们看下：
