Today, one of the small technical difficulties, now think o

that the anti-compilation code and the original code are not very different, the main difference is that the original resource references have all become numbers. 即使那些代码是混淆过的，你可以得到他的大体思路对你的开发有益无害 Prevent the APK program from being recompiled As an Android app developer, you have to face an awkward situation where your hard-to-develop apps can be easily recompiled by others.

tool of the miracle?Well, there really is.The tool is Android Studio, a joke, although we do not, but we know that the Smali file can be compiled to build, then we can look at the anti-compilation APK package name, then we create a new app, under the same package name to write a splash screen page activity, Then pack it up as an apk. Put this apk back to compile, extract the corresponding Flash screen page

hook, as well as the solution, in speaking of the case to rob red envelopes The solution is very simple, is to seize the time to judge, but this is not hundred percent accurate, Because there are a lot of uncertainties in the inside, such as the speed of the network, may determine a red envelope was robbed of time. But in a certain time to grab the bag we can determine whether to use the auto-grab package plug-in, if you want to do more intelligent, it is best to sample a number of red envelope
