各位前辈，帮忙分析这段java代码，签名检验如何跳过？

是false，哈哈，修改如下boolean bool = g.b(this);
if (!bool)
...改成
boolean bool = g.b(this);
bool=false;
if (!bool)即可，仅仅是加了一行代码

我瞎，改成trueboolean bool = g.b(this);
bool=true;
if (!bool)

好像一看就知道改成true 就行了

谢谢以上大侠们的热心回答，但我从对应的smali代码里如何修改？请指教

非常感谢！请麻烦看看对应的smali代码如何修改，楼上有代码，非常感谢！

兄弟们，谢谢你们啦！！！
我知道怎么回事啦！！！
在另外一个文件里，直接返回true就可以啦！
smali代码里，加上一行const/4 v0, 0x1，或者直接把if-lt变成if-ge就是说把条件反过来，就OK啦我是代码白痴，就懂点英文，我尝试着修改if判断句，弄了一周，今天终于让我试验出来了，哈哈
还学会很多smali的代码知识，真是感谢啊！！！收到前面几位前辈的指点，和启发！再次多谢！！！

1: 首先创建密钥库并生成密钥myKey
keytool -genkey -keystore myKeyStore.store -alias myKey
2: 用密钥对jar包进行签名
jarsigner -keystore myKeyStore xxx.jar myKey
3:对签名后的jar包进行验证
jarsigner -keystore myKeyStore -verify xxx.jar -verbose -certs---------------------

各位大侠，我又来求助了
签名检验是过关了，但，，，在一个launch_layout.xml里，下面的代码，有个广告代码，跳过倒计时3秒，谁能分析一下，如何修改下面这段密码，增加什么，或减少什么，可以跳过3秒倒计时
<?xml version="1.0" encoding="utf-8"?>
