最近把項目升級到Android Q了，發(fā)現(xiàn)不少api都已經(jīng)被Google標(biāo)注為@Deprecated了，于是對部分API進(jìn)行了適配氛魁。

適配完的方法每次在編譯打包時依然還會報警告：
警告: [deprecation] ConnectivityManager中的TYPE_WIFI已過時
這個時候可以在app/build.gradle中設(shè)置：
android {
lintOptions {
checkReleaseBuilds false
abortOnError false
}
}
下次再編譯就不會出現(xiàn)之前優(yōu)化過的那些提示了廊鸥，目前我是這樣搞的，如有不對歡迎指正伤锚。

一、網(wǎng)絡(luò)狀態(tài)

指示網(wǎng)絡(luò)的連接方式包括如下狀態(tài)：
*TRANSPORT_CELLULAR(蜂窩網(wǎng)絡(luò)) & TRANSPORT_WIFI & TRANSPORT_BLUETOOTH & TRANSPORT_ETHERNET & TRANSPORT_VPN & TRANSPORT_WIFI_AWARE & TRANSPORT_LOWPAN
*過時API:NetworkInfo類志衣，全文方法陣亡

1.對手機當(dāng)前是否連接網(wǎng)絡(luò)進(jìn)行優(yōu)化

    /**
     * 當(dāng)前是否連接網(wǎng)絡(luò)
     */
    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.當(dāng)前使用的是蜂窩網(wǎng)絡(luò)還是WIFI等相關(guān)方法進(jìn)行了優(yōu)化（Bluetooth等可自行修改）

   /**
     * 當(dāng)前使用WIFI連接網(wǎng)絡(luò)
     */
    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
        }
    }

    /**
     * 當(dāng)前使用蜂窩網(wǎng)絡(luò)連接網(wǎng)絡(luò)
     */
    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
        }
    }

最近事兒太多屯援，等手上事情忙完了再更新哈，先給個美女圖你們看下：
