【移動(dòng)應(yīng)用開發(fā)技術(shù)】Android開發(fā)如何獲取手機(jī)內(nèi)網(wǎng)IP地址與外網(wǎng)IP地址

這篇文章將為大家詳細(xì)講解有關(guān)Android開發(fā)如何獲取手機(jī)內(nèi)網(wǎng)IP地址與外網(wǎng)IP地址，在下覺得挺實(shí)用的，因此分享給大家做個(gè)參考，希望大家閱讀完這篇文章后可以有所收獲。Android是一種基于Linux內(nèi)核的自由及開放源代碼的操作系統(tǒng)，主要使用于移動(dòng)設(shè)備，如智能手機(jī)和平板電腦，由美國(guó)Google公司和開放手機(jī)聯(lián)盟領(lǐng)導(dǎo)及開發(fā)。在進(jìn)行Android應(yīng)用開發(fā)過程中，有時(shí)候會(huì)遇到獲取當(dāng)前Android設(shè)備所使用的網(wǎng)絡(luò)IP地址的場(chǎng)景，有時(shí)候需要本地的網(wǎng)絡(luò)IP地址，即局域網(wǎng)地址，更多的時(shí)候是需要當(dāng)前網(wǎng)絡(luò)的真實(shí)的對(duì)外IP地址，即真實(shí)的網(wǎng)絡(luò)地址,如大數(shù)據(jù)分析時(shí)往往需要Android設(shè)備上傳本地的外網(wǎng)地址。本文對(duì)各種IP地址的獲取進(jìn)行了總結(jié)。首先用大家比較熟悉的電腦端局域網(wǎng)地址和外網(wǎng)地址的獲取方式對(duì)比一下：（1）、電腦端局域網(wǎng)地址獲取方式，可以通過在終端命令行輸入ipconfig進(jìn)行查看，如下圖IPv地址標(biāo)識(shí)的就是本機(jī)的局域網(wǎng)地址：（2）、電腦端外網(wǎng)地址的獲取方式，可以通過在瀏覽器里面查詢，如在百度頁面搜索“IP地址查詢”查看本地外網(wǎng)地址，如下圖是筆者本機(jī)的外網(wǎng)地址：本地IP地址有兩種情況：一是wifi下，二是移動(dòng)網(wǎng)絡(luò)下wifi下獲取本地局域網(wǎng)IP地址//

}獲取外網(wǎng)地址非移動(dòng)網(wǎng)絡(luò)獲取Android設(shè)備的外網(wǎng)地址，即當(dāng)前Wifi網(wǎng)絡(luò)真正的網(wǎng)絡(luò)地址，也即是網(wǎng)絡(luò)運(yùn)營(yíng)商分配給用戶的IP地址。獲取外網(wǎng)地址的原理：通過訪問外網(wǎng)網(wǎng)站，從網(wǎng)站返回的數(shù)據(jù)中解析本地的IP地址。PS：在本地是無法獲取到外網(wǎng)的IP地址的，需要借助服務(wù)器。/**
