[英]How to run an adb command through a Java file?
I have written the following code and cannot quite figure out how to solve the error.我已经编写了以下代码,但无法弄清楚如何解决该错误。 Not sure if this information will be found useful, but I am using a Mac and using the editor IntelliJ.
不确定这些信息是否有用,但我使用的是 Mac 并使用编辑器 IntelliJ。
public class TestCode {
public static void main(String[] args) throws Exception {
Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec("adb devices");
}
}
The result is "Exception in thread "main" java.io.IOException: Cannot run program "adb": error=2, No such file or directory"结果是“线程“main”中的异常java.io.IOException:无法运行程序“adb”:错误=2,没有这样的文件或目录”
However, when I run the command "adb devicees" from the terminal I get the list of devices attached to my computer.但是,当我从终端运行命令“adb devicees”时,我会得到连接到我的计算机的设备列表。
For those interested, the following is the full stack trace.对于那些感兴趣的人,以下是完整的堆栈跟踪。

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.您需要使用
exec(String[] cmdarray)
函数来发送参数,该函数的单参数版本会在空间上拆分字符串,如果您的路径包含空格,则会带来麻烦。
you also need to specify the full path (maybe /usr/bin/adb?).您还需要指定完整路径(也许是 /usr/bin/adb?)。
Like this:像这样:
Process process = runtime.exec(new String[] {"/usr/bin/adb", "devices"});
