這篇文章主要講如何自己來做一個(gè)apk實(shí)現(xiàn)遠(yuǎn)程調(diào)試，也就是說我們先自己寫一個(gè)apk來控制是否啟用遠(yuǎn)程調(diào)試的功能，然后通過這個(gè)apk來啟用遠(yuǎn)程調(diào)試，接著基于遠(yuǎn)程adb的方式來調(diào)試以后的程序。聽起來真TM繞口。沒關(guān)系，跟著看就行了。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，這個(gè)逼格的東西并不需要你多么的了解，我們只需要知道幾條基本的命令。
設(shè)置adb的調(diào)試端口，當(dāng)端口>-1的時(shí)候，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
對應(yīng)的將端口設(shè)置為-1或者更小的數(shù)值，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adb
start adbd
好了有了這幾個(gè)命令的基礎(chǔ)，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。我又不是搞底層的。對于執(zhí)行shell命令，自有高手早已寫好的工具類，這里將源碼貼上
public class ShellUtils {
public static final String COMMAND_SU = "su";
public static final String COMMAND_SH = "sh";
public static final String COMMAND_EXIT = "exit\n";
public static final String COMMAND_LINE_END = "\n";

throw new AssertionError();
}

*/
public static CommandResult execCommand(String[] commands, boolean isRoot,
boolean isNeedResultMsg) {

continue;

// error
os.write(command.getBytes());
os.writeBytes(COMMAND_LINE_END);

process.getInputStream()));

process.getErrorStream()));
String s;
while ((s = successResult.readLine()) != null) {
successMsg.append(s);
}
while ((s = errorResult.readLine()) != null) {
errorMsg.append(s);
}
}
} catch (IOException e) {
e.printStackTrace();

public static class CommandResult {
/** result of command **/
public int result;
/** success message of command result **/

}
public CommandResult(int result, String successMsg, String errorMsg) {

我們需要用到的方法是
public static CommandResult execCommand(String[] commands, boolean isRoot,
boolean isNeedResultMsg) {
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。oh天，忘了說，你的手機(jī)必須要先root才能來做這件事情，至于root的方式，太多了，什么root大師，xx大師。
參數(shù)3：是否需要返回結(jié)果，這個(gè)可有可無，如果你選擇返回結(jié)果，我想多半是你想知道這些命令有沒有執(zhí)行成功，你只需要判斷
CommandResult .result
的值是否為0，對的，linux就是這樣，等于0就是成功了的意思
ok，剩下的活你應(yīng)該會(huì)做了，寫一個(gè)button控件，監(jiān)聽點(diǎn)擊事件，在事件中調(diào)用這個(gè)方法。至于參數(shù)一怎么寫，當(dāng)需要打開wifi調(diào)試的時(shí)候就這樣寫
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，現(xiàn)在你可以將apk編譯到你的手機(jī)上，并且打開wifi調(diào)試，接著在如下目錄
sdk\platform-tools
你可以通過 shift+右鍵 的方式有個(gè)“在此處打開命令行”。然后輸入
adb connect xxxx
xxxx 是你的手機(jī)ip，端口不用輸，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，你的eclipse里的device窗口就顯示你的破手機(jī)已經(jīng)連接上了，現(xiàn)在你可以丟掉數(shù)據(jù)線，靜靜的裝逼了。真是有逼格的燒連啊。
斷開連接，你可以在手機(jī)上斷開，也可以在pc上通過
adb disconnect xxxx
來斷開，當(dāng)然在手機(jī)上斷開保險(xiǎn)一點(diǎn)。
好的，有問題的同學(xué)可以留言，啊哈哈哈哈哈，這都不會(huì)，你好笨啊。
