java - 解析Android getprop

转载作者：行者123 更新时间：2023-12-01 19:06:19

我正在尝试解析 getprop安卓的命令。这是我正在使用的代码。

public class PropManager {
    public String propReader() {
        InputStream inputstream = null;
        try {
            inputstream = Runtime.getRuntime().exec("/system/bin/getprop")
                    .getInputStream();
        } catch (IOException e) {
            e.printStackTrace();
        }
        String propval = "";
        try {

            propval = new Scanner(inputstream).useDelimiter("\\A").next();
            System.out.println(propval);

        } catch (NoSuchElementException e) {
            e.printStackTrace();
        }
        return propval;
    }

    public String DeviceProp(String propval) {
        String deviceprop = "none";
        try {
            Scanner scanner = new Scanner(propval).useDelimiter("\\n");
            scanner.findWithinHorizon(
                    Pattern.compile("\\[ro.product.model\\].*\\[([^\\0]+)\\]"),
                    0);
            mbvsprop = scanner.match().group(1);
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return deviceprop;
    }

}

但是我收到错误，这是 StackTraCE :

最佳答案

仅通过阅读代码和大量输出很难完全了解您想要完成的任务，但我会尝试一下。

具体来说，不可能知道正则表达式中 [^\\0] 的含义，但如果将其替换为点并使用问号使其变为非-贪婪，那么下面的一行，替换代码中的一行，应该做你正在寻找的事情......

                Pattern.compile("\\[ro.product.model\\].*\\[(.+?)\\]"),
