从有根的Andr​​oid应用程序运行的二进制 [英] Run binary from with root Android Application

问题描述

我想运行一个二进制的的/ dev /本地命名原生（我把它通过ADB），具有root权限。 为了做到这一点，我写了下面code：

I want to run a binary at /dev/local named native(I pushed it through adb), with root permission. In order to achieve that, I wrote the following code:

    try {
        root=Runtime.getRuntime().exec("su");
        DataOutputStream os = new DataOutputStream(root.getOutputStream());
        DataInputStream osRes = new DataInputStream(root.getInputStream());
        os.writeBytes("/data/local/native\n");
        os.flush();
        TextView output=(TextView)findViewById(R.id.textview);
        output.append(osRes.readLine());
        root.waitFor();
    } catch (Exception e) {
        // TODO Auto-generated catch block
        Toast.makeText(this, e.toString() , Toast.LENGTH_SHORT).show();
    }

这给了我一个 NullPointerException异常。所以，我试图将其更改为：

This gave me a NullPointerException.So, I tried changing it to:

    try{
        root=Runtime.getRuntime().exec("su");
        root.waitFor();
        DataOutputStream os = new DataOutputStream(root.getOutputStream());
        DataInputStream osRes = new DataInputStream(root.getInputStream());
        os.writeBytes("/data/local/native\n");
        os.flush();
        TextView output=(TextView)findViewById(R.id.textview);
        output.append(osRes.readLine());
        root.waitFor();
    } catch (Exception e) {
        // TODO Auto-generated catch block
        Toast.makeText(this, e.toString() , Toast.LENGTH_SHORT).show();
    }

有了这个，我得到BrokenPipe错误。

With this I get BrokenPipe error.

请帮帮我，我想运行具有root权限的二进制文件，有没有另一种方式或者是什么，我做错了什么？

Kindly help me, I want to run a binary with root privileges, is there any alternative way or what is it that I am doing wrong?

推荐答案

尝试运行苏-c /路径/要/执行。
