如何通过Java文件运行adb命令？ [英] How to run an adb command through a Java file?

问题描述

我写了下面的代码，无法完全解决该错误。不知道这些信息是否有用，但是我使用的是Mac，并且使用的是IntelliJ编辑器。

I have written the following code and cannot quite figure out how to solve the error. Not sure if this information will be found useful, but I am using a Mac and using the editor IntelliJ.

public class TestCode {
    public static void main(String[] args) throws Exception {
        Runtime runtime = Runtime.getRuntime();
        Process process = runtime.exec("adb devices");
    }
}

结果为线程 main中的异常 java .io.IOException：无法运行程序 adb：error = 2，没有此类文件或目录

The result is "Exception in thread "main" java.io.IOException: Cannot run program "adb": error=2, No such file or directory"

但是，当我从命令行运行命令 adb devicees时终端，我会获得连接到计算机的设备列表。

However, when I run the command "adb devicees" from the terminal I get the list of devices attached to my computer.

对于那些感兴趣的人，以下是完整的堆栈跟踪。

推荐答案

您需要使用 exec（String [] cmdarray）函数发送参数，该函数的单个参数版本会在空间上拆分字符串，如果您的路径存在，则会带来麻烦包含空格。

You need to use the exec(String[] cmdarray) function to send arguments, the single argument version of the function splits the string on space, and that spells trouble if your path contains spaces.

您还需要指定完整路径（也许是/ usr / bin / adb？）。

you also need to specify the full path (maybe /usr/bin/adb?).

就像这样：

Process process = runtime.exec(new String[] {"/usr/bin/adb", "devices"});
