java - 尝试在 Android 操作系统中启动脚本执行的权限被拒绝

Question

在 Android 操作系统中启动 bash shell 脚本时遇到问题。使用 Android Studio 和 Google Pixel 模拟器。脚本执行时出现“权限被拒绝”。脚本的权限是“755”。如果我这里有什么问题请告诉我。注意-当我这样做时:
%adb shell
%run-as com.example.myapplication.
%./getinfo.sh.
运行正常。

当脚本在 Android 模拟器中应用程序的 Java 代码中启动时，它不会运行。如果我有什么问题请告诉我。
谢谢!

相关java代码--

String command="/data/data/com.example.myapplication/getinfo.sh"; 
ProcessBuilder builder = new ProcessBuilder(command); 
Process p = builder.start();
p.waitFor();.  

logcat列出的错误是--

Answer 1

我终于能够通过设置在 Android 上执行脚本:

ProcessBuilder pb = new ProcessBuilder();
pb.command("/system/bin/sh","test.sh");

pb.redirectErrorStream(true);
File workingDirectory = new File(localPath);
pb.directory(workingDirectory);  //set the working directory for this process

Process process = pb.start();

where "localPath" is passed in after being determined via:

Context c = getApplicationContext();
final String localPath=c.getFilesDir().getPath()

虽然这是一个很好的步骤，但我现在发现我无法运行导入到/data/data/com.example.myapplication 中工作区域的任何二进制文件。将为此开始一个新帖子。
