添加下面的代码，用新的混淆字典，随机大小写字母组合

package com.jiuhong.mbtirgtest.util;import java.io.FileWriter;
import java.io.IOException;
import java.util.HashSet;
import java.util.Random;
import java.util.Set;public class ObfuscationDictionaryGeneratorUtil {public static void generateObfuscationDictionary(String filePath, int count) {Set<String> uniqueWords = new HashSet<>();  // 使用 Set 确保唯一性while (uniqueWords.size() < count) {uniqueWords.add(generateRandomWord(3, 10));}try (FileWriter writer = new FileWriter(filePath)) {for (String word : uniqueWords) {writer.write(word + "\n");}System.out.println("混淆字典已生成: " + filePath);} catch (IOException e) {System.err.println("生成混淆字典失败: " + e.getMessage());}}private static String generateRandomWord(int minLength, int maxLength) {Random random = new Random();int wordLength = random.nextInt(maxLength - minLength + 1) + minLength;StringBuilder word = new StringBuilder(wordLength);for (int i = 0; i < wordLength; i++) {char randomChar = (char) (random.nextBoolean() ? 'A' + random.nextInt(26) : 'a' + random.nextInt(26));word.append(randomChar);}return word.toString();}
}

生成字典文件

        // 调用方法生成混淆字典String filePath = this.getFilesDir().getAbsolutePath() + "/obfuscation_dictionary.txt";int count = 10000; // 生成 10000 条记录ObfuscationDictionaryGeneratorUtil.generateObfuscationDictionary(filePath, count);

在Device Explorer找到这个文件

/data/user/0/com.j.mt/files/obfuscation_dictionary.txt

拖到APP目录下

在混淆文件中添加规则

#用于字段名和方法名混淆。
-obfuscationdictionary obfuscation_dictionary.txt
#用于类名混淆。
-classobfuscationdictionary obfuscation_dictionary.txt
#用于包名混淆。
-packageobfuscationdictionary obfuscation_dictionary.txt
