快乐下载apk去次数限制思路记录

准备工作：

1、一台已root手机或模拟器；
2、MT管理器（或NP管理器）；
3、开发助手；
4、快乐下载apk。

步骤：

由于apk没加固，所以可以直接MT管理器修改。

一开始是想从isvip或者getvip之类的方法名下手，但发现并没有直接的修改思路（能力有限）。
不过并非一无所获，我们通过搜索vip方法名定位到Vip这个类，进入之后，最后通过阅读代码（如下所示），决定从判断上面下手：

        if (res.getShops() == null) {
            ToastUtils.toast("获取信息失败，请检查您的网络");
        } else {
            new XPopup.Builder(context).dismissOnTouchOutside(false).dismissOnBackPressed(false).asCustom(new Vip$1(context, res, also, todayCount, observableEmitter, context)).show();

        }
    }

    static void lambda$refresh$5(Throwable e) throws Throwable {
    }
}

其中最重要的部分就是包含判断的部分：

    static void lambda$can$3(String also, int count, Context context, ObservableEmitter observableEmitter) throws Throwable {
        refresh();
        UserInfo info = AppPref.get().getUserInfo();
        if (info != null && (info.getVip() == 94 || info.getVip() == 93 || info.getVip() == 100)) {
            observableEmitter.onNext(-1);
            return;
        }
        NativeConfig nativeConfig = NativeConfig.getInstance();
        int todayCount = nativeConfig.readInt(getDayKey() + "_" + also);
        PrintStream printStream = System.out;
        printStream.println("今日已使用：" + todayCount);
        if (todayCount < count) {
            if (todayCount == 0) {
                Observable compose = HttpClient.getApi().getShops().compose(RxPlugin.fromNewToMainThread());
                -$.Lambda.Vip.zK7SieMyZ-Sq4SwE-E0hqmeyZk4 r3 = new -$.Lambda.Vip.zK7SieMyZ-Sq4SwE-E0hqmeyZk4(context, also, todayCount, observableEmitter);
                Objects.requireNonNull(observableEmitter);
                compose.subscribe(r3, new -$.Lambda.9V4x4hT-pqcFjlu4mhGdRyjZzlw(observableEmitter));
                return;
            }
            NativeConfig nativeConfig2 = NativeConfig.getInstance();
            nativeConfig2.putInt(getDayKey() + "_" + also, todayCount + 1);
            observableEmitter.onNext(Integer.valueOf(todayCount + 1));
            return;
        }
        HttpClient.getApi().getShops().compose(RxPlugin.fromNewToMainThread()).subscribe(new -$.Lambda.Vip.JC0r5-ftHAi3IGOWgJtQmErslSI(context), new -$.Lambda.Vip.SXjn20c6grLvbhfrrdIaMPmapr0(observableEmitter));
    }

通过阅读可知该段代码大致意思为，判断info.Getvip()返回的值是否非空并且等于94、93、100其中一个数字，是则执行observableEmitter.onNext(-1);，否则返回继续执行后续代码，根据实际使用可推测后续代码是非vip的情况下计算每日免费使用次数，我们并不希望执行的部分。

通过对java代码的解读，可以回去看前面的smali代码，很快定位到判断相关的代码：

    .line 61
    .local v0, "info":Lcom/one/downloadtools/ui/user/m/UserInfo;
    if-eqz v0, :cond_2f    //判断v0是否等于0，是则跳转到cond_2f

    invoke-virtual {v0}, Lcom/one/downloadtools/ui/user/m/UserInfo;->getVip()I

    move-result v1

    const/16 v2, 0x5e      // v2的值是5e，也就是十进制的94

    if-eq v1, v2, :cond_25   //如果v1等于v2，则跳转到cond_25

    invoke-virtual {v0}, Lcom/one/downloadtools/ui/user/m/UserInfo;->getVip()I

    move-result v1

    const/16 v2, 0x5d   // v2的值是5d，也就是十进制的93

    if-eq v1, v2, :cond_25      //如果v1等于v2，则跳转到cond_25

    invoke-virtual {v0}, Lcom/one/downloadtools/ui/user/m/UserInfo;->getVip()I

    move-result v1

    const/16 v2, 0x64  // v2的值是64，也就是十进制的100

    if-ne v1, v2, :cond_2f  //如果v1不等于v2，则跳转到cond_2f

那么此时就明朗了，我们的目标就是不管v0是否为空，v1v2是否相等，我们都跳转到cond_25而不进入原来的cond_2f，所以我们只需要将cond_2f都修改为cond_25即可：
