从 Java 程序执行 ADB 命令 [英] Execute ADB command from Java program

问题描述

我正在开发的程序使用 ADB(Android 调试桥)将文件发送到我的手机:

The program I'm working on uses ADB (Android Debug Bridge) to send files to my phone:

for (String s : files)
    String cmd = "adb -s 0123456789ABCDEF push " + s + " /mnt/sdcard/" + s;
    try {
        InputStream is = Runtime.getRuntime().exec(cmd).getInputStream();
        while (is.read() != -1) {}
    } catch (IOException e) {
        e.printStackTrace();
    }

我希望程序一直等到 ADB 完成传输，但 ADB 作为守护进程运行，因此永远不会完成.但程序会立即继续，不知何故文件没有发送到我的手机(日志中没有例外).当我从控制台运行命令时，它可以正常工作.

I want the program to wait until ADB finished the transmission, but ADB runs as a daemon and therefore never finishes. But the program continues immideately and somehow the files aren't sent to my phone (no exceptions in log). When I run the command from console, it's working without problems.

我做错了什么?如何正确通过 ADB 发送文件?

What am I doing wrong? How do I send files via ADB correctly?

注意:is.read() == -1 将不起作用，因为 ADB 守护进程将所有输出写入系统标准输出.我试过将它转发到一个文本文件中.它保持为空，输出仍然写入终端

NOTE: the is.read() == -1 won't work, because the ADB daemon writes all output to the system standard output. I've tried forwarding it into a textfile. It stayed empty and the output was still written to the terminal instead

EDIT:读取 ADB 进程的 ErrorStream 返回每个 adb push 命令的 adb 帮助.再次:exact 命令(从 Eclipse 控制台复制)在终端中工作

EDIT: Reading the ErrorStream of the ADB process returned the adb help for each adb push-command. Again: The exact commands (copied from Eclipse console) work in a terminal

EDIT 2:使用 ProcessBuilder 而不是 RUNtime.getRuntime.exec() 导致以下错误:

EDIT 2: Using a ProcessBuilder instead of RUntime.getRuntime.exec() resulted in the following error:

java.io.IOException: Cannot run program "adb -s 0123456789ABCDEF push "inputfile "outputfile""": error=2, File or directory not found

在 ProcessBuilder 的 start() 方法中使用 ADB 的绝对路径 (/usr/bin/adb) 时也会发生同样的情况.inputfile 和 outputfile 字符串也是绝对路径，如 /home/sebastian/testfile 并且肯定存在.从终端运行命令(打印字符串cmd"，复制和粘贴)时，evreything 仍然可以正常工作.

at the ProcessBuilder's start()-method The same happens when using an absolute path for ADB (/usr/bin/adb). The inputfile and outputfile Strings are also absolute paths, like /home/sebastian/testfile and definitely exist. When running the commands from terminal (string "cmd" printed, copy&paste), evreything still works fine.

推荐答案

我终于搞定了:

ProcessBuilder pb = new ProcessBuilder("adb", "-s", "0123456789ABCDEF", "push", inputfile, outputfile);
Process pc = pb.start();
pc.waitFor();
System.out.println("Done");

我不知道 ProcessBuilder 对字符串中的空格有什么问题，但最后，它正在工作...

I don't know what problems ProcessBuilder has with spaces in a string, but finally, it's working...
