如何在android中存储从Base64到string的巨大转换字符串

String base64String = "SGVsbG8gV29ybGQ="; // Base64字符串
byte[] bytes = Base64.decode(base64String, Base64.DEFAULT);

String result = new String(bytes, StandardCharsets.UTF_8);

import android.util.Base64;
import java.nio.charset.StandardCharsets;

public class Base64Utils {
    public static String base64ToString(String base64String) {
        byte[] bytes = Base64.decode(base64String, Base64.DEFAULT);
        return new String(bytes, StandardCharsets.UTF_8);
    }
}

String base64String = "SGVsbG8gV29ybGQ="; // Base64字符串
String result = Base64Utils.base64ToString(base64String);
