這篇文章主要講如何自己來(lái)做一個(gè)apk實(shí)現(xiàn)遠(yuǎn)程調(diào)試，也就是說(shuō)我們先自己寫(xiě)一個(gè)apk來(lái)控制是否啟用遠(yuǎn)程調(diào)試的功能追迟，然后通過(guò)這個(gè)apk來(lái)啟用遠(yuǎn)程調(diào)試溶其，接著基于遠(yuǎn)程adb的方式來(lái)調(diào)試以后的程序。聽(tīng)起來(lái)真TM繞口敦间。沒(méi)關(guān)系瓶逃，跟著看就行了束铭。實(shí)現(xiàn)這個(gè)目標(biāo)分為3步。
1.了解shell命令
2.如何在android上執(zhí)行shell
3.pc端的命令
1.了解shell命令
好吧厢绝，這個(gè)逼格的東西并不需要你多么的了解契沫，我們只需要知道幾條基本的命令。
設(shè)置adb的調(diào)試端口昔汉，當(dāng)端口>-1的時(shí)候懈万，adb是wifi調(diào)試，我們默認(rèn)的一般將端口設(shè)置為5555
setprop service.adb.tcp.port 5555
對(duì)應(yīng)的將端口設(shè)置為-1或者更小的數(shù)值靶病，則將調(diào)試方式變?yōu)榱藆sb調(diào)試
setprop service.adb.tcp.port -1
關(guān)閉adb
stop adbd
打開(kāi)adb
start adbd
好了有了這幾個(gè)命令的基礎(chǔ)会通，就可以實(shí)現(xiàn)usb和wifi調(diào)試方式的轉(zhuǎn)換了
2.如何在android上執(zhí)行shell
怎么執(zhí)行，鬼才管呢娄周。我又不是搞底層的涕侈。對(duì)于執(zhí)行shell命令，自有高手早已寫(xiě)好的工具類(lèi)煤辨，這里將源碼貼上

我們需要用到的方法是

解釋下三個(gè)參數(shù)的意思
參數(shù)1：需要執(zhí)行的命令數(shù)組
參數(shù)2：是否已經(jīng)root過(guò)裳涛。oh天，忘了說(shuō)众辨，你的手機(jī)必須要先root才能來(lái)做這件事情调违，至于root的方式，太多了泻轰，什么root大師，xx大師且轨。
參數(shù)3：是否需要返回結(jié)果浮声，這個(gè)可有可無(wú)，如果你選擇返回結(jié)果旋奢，我想多半是你想知道這些命令有沒(méi)有執(zhí)行成功泳挥，你只需要判斷
CommandResult .result
的值是否為0，對(duì)的至朗，linux就是這樣屉符，等于0就是成功了的意思
ok，剩下的活你應(yīng)該會(huì)做了锹引，寫(xiě)一個(gè)button控件矗钟，監(jiān)聽(tīng)點(diǎn)擊事件，在事件中調(diào)用這個(gè)方法嫌变。至于參數(shù)一怎么寫(xiě)吨艇，當(dāng)需要打開(kāi)wifi調(diào)試的時(shí)候就這樣寫(xiě)
String[] commands = {
setprop service.adb.tcp.port 5555,
stop adbd,
start adbd
}
當(dāng)需要關(guān)閉wifi調(diào)試的時(shí)候，只需要將5555改為-1就行
3.pc端的命令
好的腾啥，現(xiàn)在你可以將apk編譯到你的手機(jī)上东涡，并且打開(kāi)wifi調(diào)試冯吓，接著在如下目錄
sdk\platform-tools
你可以通過(guò) shift+右鍵 的方式有個(gè)“在此處打開(kāi)命令行”。然后輸入
adb connect xxxx
xxxx 是你的手機(jī)ip疮跑，端口不用輸组贺，默認(rèn)就是5555，手機(jī)ip你可以在設(shè)置-關(guān)于手機(jī)-手機(jī)狀態(tài) 中找到
于是“噌”的一下祖娘，你的eclipse里的device窗口就顯示你的破手機(jī)已經(jīng)連接上了失尖，現(xiàn)在你可以丟掉數(shù)據(jù)線(xiàn)，靜靜的裝逼了贿条。真是有逼格的燒連啊雹仿。
斷開(kāi)連接，你可以在手機(jī)上斷開(kāi)整以，也可以在pc上通過(guò)
adb disconnect xxxx
來(lái)斷開(kāi)胧辽，當(dāng)然在手機(jī)上斷開(kāi)保險(xiǎn)一點(diǎn)。
好的公黑，有問(wèn)題的同學(xué)可以留言邑商，啊哈哈哈哈哈，這都不會(huì)凡蚜，你好笨啊人断。
