Android apk通过jadx的这种广告倒计时方法是如何工作的？

apk通过jadx的这种广告倒计时方法是如何工作的

我使用jadx反编译了一个apk，经过几个小时的反复思考和调试，找到了以下方法。看来这是为了迷惑像我这样的人

倒计时持续5秒。然后允许用户跳过广告

代码如下：

/* 69 */        public static String a(long j, int i) {
                    String str;
                    long j2;
                    String str2;
                    String str3;
/* 70 */            StringBuilder sb = new StringBuilder();
/* 70 */            if (j < 0) {
/* 70 */                str = "-";
                    } else {
/* 96 */                str = "";
                    }
/* 71 */            sb.append(str);
/* 72 */            long abs = Math.abs(j);
/* 73 */            long j3 = abs / 60;
/* 74 */            long j4 = j3 / 60;
/* 74 */            if (j4 > 0) {
/* 77 */                i = Math.max(i, 5);
/* 76 */                j2 = j3 % 60;
                    } else {
/* 96 */                j2 = j3;
                    }
/* 79 */            String l = Long.toString(abs % 60);
/* 80 */            if (l.length() == 1) {
/* 81 */                String valueOf = String.valueOf(l);
/* 81 */                str2 = valueOf.length() == 0 ? new String("0") : "0".concat(valueOf);
                    } else {
/* 96 */                str2 = l;
                    }
/* 82 */            String l2 = Long.toString(j2);
/* 83 */            if (l2.length() != 1) {
/* 92 */                str3 = l2;
                    } else if (i > 3) {
/* 84 */                String valueOf2 = String.valueOf(l2);
/* 84 */                str3 = valueOf2.length() == 0 ? new String("0") : "0".concat(valueOf2);
                    } else {
/* 92 */                str3 = l2;
                    }
/* 84 */            if (i > 4) {
/* 87 */                sb.append(j4);
/* 87 */                sb.append(":");
/* 87 */                sb.append(str3);
/* 87 */                sb.append(":");
/* 87 */                sb.append(str2);
/* 88 */                return ((xv) a.get()).a(sb.toString());
                    }
/* 90 */            sb.append(str3);
/* 90 */            sb.append(":");
/* 90 */            sb.append(str2);
/* 91 */            return ((xv) a.get()).a(sb.toString());
                }

这段代码已经被混淆了，所以进行反向工程将非常困难，尤其是从这段代码中。这可能更容易描述你想要达到的效果，因为有很多方法可以在Android中创建文本的动画倒计时。伊恩，我想把广告时间减少到0！我贴了一个结果日志作为答案，小李删除了它们！现在已成功添加到问题。是的，答案应用于回答问题，而不是添加有关问题的其他详细信息。
