利用shell命令实现Eeclipse对Android的远程调试

这篇文章主要讲如何自己来做一个apk实现远程调试,也就是说我们先自己写一个apk来控制是否启用远程调试的功能,然后通过这个apk来启用远程调试,接着基于远程adb的方式来调试以后的程序。听起来真TM绕口。没关系,跟着看就行了。实现这个目标分为3步。

1.了解shell命令
2.如何在android上执行shell
3.pc端的命令

1.了解shell命令

好吧,这个逼格的东西并不需要你多么的了解,我们只需要知道几条基本的命令。
设置adb的调试端口,当端口>-1的时候,adb是wifi调试,我们默认的一般将端口设置为5555
setprop service.adb.tcp.port 5555
对应的将端口设置为-1或者更小的数值,则将调试方式变为了usb调试
setprop service.adb.tcp.port -1
关闭adb
stop adbd
打开adb
start adbd
好了有了这几个命令的基础,就可以实现usb和wifi调试方式的转换了

2.如何在android上执行shell

怎么执行,鬼才管呢。我又不是搞底层的。对于执行shell命令,自有高手早已写好的工具类,这里将源码贴上

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";

    private ShellUtils() {
        throw new AssertionError();
    }

    /**
     * check whether has root permission
     * 
     * @return
     */
    public static boolean checkRootPermission() {
        return execCommand("echo root", true, false).result == 0;
    }

    }
}

我们需要用到的方法是

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

解释下三个参数的意思
参数1:需要执行的命令数组
参数2:是否已经root过。oh天,忘了说,你的手机必须要先root才能来做这件事情,至于root的方式,太多了,什么root大师,xx大师。
参数3:是否需要返回结果,这个可有可无,如果你选择返回结果,我想多半是你想知道这些命令有没有执行成功,你只需要判断
CommandResult .result
的值是否为0,对的,linux就是这样,等于0就是成功了的意思
ok,剩下的活你应该会做了,写一个button控件,监听点击事件,在事件中调用这个方法。至于参数一怎么写,当需要打开wifi调试的时候就这样写

String[] commands = {
setprop service.adb.tcp.port 5555,
stop adbd,
start adbd
}

当需要关闭wifi调试的时候,只需要将5555改为-1就行

3.pc端的命令

好的,现在你可以将apk编译到你的手机上,并且打开wifi调试,接着在如下目录

sdk\platform-tools

你可以通过 shift+右键 的方式有个“在此处打开命令行”。然后输入
adb connect xxxx
xxxx 是你的手机ip,端口不用输,默认就是5555,手机ip你可以在设置-关于手机-手机状态 中找到
于是“噌”的一下,你的eclipse里的device窗口就显示你的破手机已经连接上了,现在你可以丢掉数据线,静静的装逼了。真是有逼格的烧连啊。
断开连接,你可以在手机上断开,也可以在pc上通过

adb disconnect xxxx

来断开,当然在手机上断开保险一点。

好的,有问题的同学可以留言,啊哈哈哈哈哈,这都不会,你好笨啊。
