批量重新命名簽名好以後的檔案

應用加固後，再次簽名的時候(使用了Qihoo360 Apk Signer),簽名後的檔名類似這樣AS18_signed_Aligned.apk，沒有攜帶版本號，如果那麼多渠道一個一個手動去改，麻煩不說還容易錯。 所以就自己寫個批量重新命名的工具類。 重新命名前檔名為AS18_signed_Aligned.apk, 重新命名後檔名為AS18_signed_輸入的內容.apk

import java.io.File;
import java.util.Scanner;

public class Test {

    private static String sVersionName;
    private static String sReplaceName = "Aligned";

    public static void main(String[] ar) {


//        File file = new File("");
//        System.out.println(file.getAbsoluteFile());
        sVersionName =  getVersionCode();

        File directory = getCurrentDirectory();

        getFileName(directory);

    }

    private static File getCurrentDirectory() {
        File file = new File("");
        System.out.println(file.getAbsoluteFile());
        return file.getAbsoluteFile();
    }

    private static String getVersionCode() {
        System.out.println("input your version code ,like [v1.1.8]");
        Scanner scanner = new Scanner(System.in);
        String code = scanner.next();
        System.out.println("input version code success , code is = " + sVersionName);
        return code;
    }

    private static void getFileName(File file) {
        if (file == null) {
            System.out.println("file == null");
            return;
        }

        if (sVersionName == null) {
            System.out.println("sVersionName == null");
            return;
        }
        if (file.isDirectory()) {
            File[] files = file.listFiles();
            if (files == null) {
                System.out.println("files == null");
                return;
            }

            System.out.println("files.length  =  " + files.length);
            for (int i = 0; i < files.length; i++) {
                getFileName(files[i]);
            }
        } else if (file.isFile()) {

            String name = file.getName();
            if (name.contains(sReplaceName)) {
                String path = file.getAbsolutePath().replace(sReplaceName, sVersionName);
                boolean aligned = file.renameTo(new File(path));
                if (aligned) {
                    System.out.println("rename success, path : " + path);
                } else {
                    System.out.println("warning !! rename failure, path : " + path);
                }
            }

        } else {
            System.out.println("file is not Directory or File");
        }
    }
}
