一、课程目标

借助已学知识完成样本软件的去除签名校验、去广告与更新、布局优化

二、工具

1.样本软件
2.jadx-gui
3.MT管理器/NP管理器
4.算法助手
5.开发助手

三、课程内容

全家桶：顾名思义，这些影视app都是一套源码开发的，多个渠道分发只是换了个包名和皮肤

1.去除广告

关键字:initsdk、loadad、initad等

通过免广告关键字来实现部分广告的去除

public void O(SaiUserInfo saiUserInfo, boolean z) {  
        g0.i(BaseApp.getInstance(), saiUserInfo);  //获取用户信息
        if (z) {  
            v.c().q(SaiSPKey.appToken, saiUserInfo.getToken());  //获取Token
        }  
        this.e.set(saiUserInfo);  
        this.h.setValue(saiUserInfo.getPic());  //设置用户头像
        if (saiUserInfo.getLogin_type() == 1) {  //判断登录状态，并设置用户信息
            this.g.set("点击登录");  
            this.f.set(Boolean.FALSE);  
        } else {  
            this.g.set(saiUserInfo.getNickname());  
            this.f.set(Boolean.TRUE);  
        }  
        ObservableField observableField = this.i;  
        observableField.set("ID:" + saiUserInfo.getUser_id());  //获取用户ID
        ObservableField observableField2 = this.j;  
        observableField2.set(SaiAppUtils.d(saiUserInfo.getInvited_count() + "人"));  //获取用户邀请人数
        if (saiUserInfo.getInvited_count() > 0) {  
            ObservableField observableField3 = this.k;  
            observableField3.set(SaiAppUtils.d(N(saiUserInfo.getInvited_count()) + "天 "));  
        } else {  
            this.k.set(SaiAppUtils.d("0天"));  
        }  
        if (saiUserInfo.getFree_time() * 1000 > System.currentTimeMillis()) {  //获取免广告时间
            this.n.set(0);  
            this.m.set(d.a(Long.valueOf(saiUserInfo.getFree_time() * 1000)));  
            this.l.set("剩余免广告：");  
            BaseApp.getInstance().setFreeTime(saiUserInfo.getFree_time() * 1000);  
            return;  
        }  
        this.l.set("邀请好友获得终身免广告特权");  
        this.n.set(8);  
        BaseApp.getInstance().setFreeTime(0L);  
    }

public void initData() {
        super.initData();

                home.php?mod=space&uid=1892347 // io.reactivex.functions.Consumer
                public final void accept(Object obj) {
                    SaiSplashActivity.this.g((SaiPrivateEvent) obj);
                }
            }));
            a0.a.h(this);
            return;
        }
        try {

            }
        } else {
            v.c().s("extend_java_aa", true);
        }
        if (g2 == 0) {
            showLoaddingDialog();
            ((SaiSplashViewModel) this.viewModel).b(b.s.c.b.a().c(SaiAppInitEvent.class).observeOn(AndroidSchedulers.mainThread()).subscribe(new Consumer() { // from class: b.l.i.v.a

                }
            }));
        }
        g.a.a(g2);
        int i2 = g2 + 1;
        v.c().m(SaiSPKey.INSTANCE.getLaunchCount(), i2);
        c0 c0Var = c0.a;
        if (c0Var.f3990g == -1) {
            c0Var.f3990g = i2;
        }
        if (g2 != 0) {
            if (NetworkUtils.c()) {
                ((SaiSplashViewModel) this.viewModel).n();
                if (c0Var.l("1")) {
                    showLoaddingDialog();
                    SaiSplashAdActivity.invoke(this);
                    finish();
                } else {
                    n(b.DELAY);
                }
            } else {
                n(b.NONET);

        if (i.c(d.f().toString(), c0Var.f3986c).equals(c0Var.j(R.string.app_cudgel))) {

.method public getFree_time()J
    .registers 3

    .line 1
    iget-wide v0, p0, Lcom/pencil/saibeans/SaiUserInfo;->free_time:J

    const-wide v0, 0x32d57bf5e8L

    return-wide v0
.end method

2.去除签名校验

1.核心破解，免签名安装
2.一键去签名工具

3.手动分析签名校验

.method public static f()Ljava/util/List;
    .registers 2
    .annotation build Landroidx/annotation/NonNull;
    .end annotation

    .annotation system Ldalvik/annotation/Signature;
        value = {
            "()",
            "Ljava/util/List<",
            "Ljava/lang/String;",
            ">;"
        }
    .end annotation

    .line 1
    new-instance v0, Ljava/util/ArrayList;

    invoke-direct {v0}, Ljava/util/ArrayList;-><init>()V

    const-string v1, "F9:6C:E9:5F:D5:47:BE:DF:81:15:E3:71:8A:10:54:45" 
    #创建了一个新的 ArrayList 实例，然后向列表中添加了一个字符串常量 "F9:6C:E9:5F:D5:47:BE:DF:81:15:E3:71:8A:10:54:45"

    invoke-virtual {v0, v1}, Ljava/util/ArrayList;->add(Ljava/lang/Object;)Z

    return-object v0
.end method

3. 去除更新弹窗

public static boolean a(boolean z, SaiUpgradeInfo saiUpgradeInfo) {  
        if (!a.b.b() && saiUpgradeInfo != null) {  
            try {  
                //获取版本号进行对比
                if (saiUpgradeInfo.getVersion_code() >= b.c.a.b.d.i()) {  
                    boolean b2 = v.c().b(SaiSPKey.INSTANCE.getUpgrade_dialog(), false);  
                    if (z || !b2) {  
                        if (saiUpgradeInfo.getIs_same() == 1) {  
                            v c = v.c();  
                            if (!c.b("appUpgrade_" + saiUpgradeInfo.getVersion_code(), false)) {  
                                new d(b.c.a.b.a.h(), saiUpgradeInfo).show();  
                                v c2 = v.c();  
                                c2.s("appUpgrade_" + saiUpgradeInfo.getVersion_code(), true);  
                                return true;  
                            }  
                        } else if (saiUpgradeInfo.getVersion_code() > b.c.a.b.d.i()) {  
                            new d(b.c.a.b.a.h(), saiUpgradeInfo).show();  
                            return true;  
                        } else if (z) {  
                            ToastUtils.v("已经是最新版本");  
                        }  
                        e0.b("========>>> 包升级更新：${it.url}");  
                    }  
                } else if (z) {  
                    ToastUtils.v("已经是最新版本");  
                }  
            } catch (Exception unused) {  
            }  
        }  
        return false;  
    }

4.布局优化

1.修改xml中的属性值

android:visibility="gone"

2.上帝模式优化布局
