Complete analysis of Android security attack and defense, decompilation and obfuscation technologies (I) I have been hesitant to write this article before. After all, it is not proud to decompile other programs. However, from a technical point of view, it is indeed a very useful skill to master the decompilation function, which may not be used very often, that's a headache. In addition, since someone else c

According to the latest Websense research, Android has encountered more security problems than other competitors. Compared with iOS and WP systems, Android has more opportunities to access unofficial market applications, in addition, its applications are easily repackaged and distributed by malware makers, so that users do not understand the differences after ins

By convention, I wrote it above: maybe in the process of learning Android, everyone will learn a lot of basic knowledge like me, and a lot of knowledge points can also be said 123, however, these isolated points are too fragmented after all. Therefore, I want to take the most classic mobile security guard project as an example from today and exercise on my own. I also want to communicate with you, I hope ev
