No doubt android has grown as the best smart phone operating system during recent times. Android has such powerful applications which organize our daily tasks and maximize work efficiency. However it has also raised some serious issues regarding software theft protection. The openness of android platform has made copy protection of applications difficult.
Piracy Violation Stats
Google is adopting new ways and techniques to provide secure environment to android developers, but past statistics show that it will be a hard nut to crack. Following charts reflect how it is important to stop this illegal activity.
Software piracy is the rising concern for android operating system. Whether it is an android application developer or a web developer, he definitely wants to enjoy maximum revenue from his developed application. But the reverse engineering process of android applications has doubted that. People change the application code and make it available online for free downloading. This is totally disaster for any developer who puts all his efforts in creating such master piece and in the end no reward for him.
Reverse Engineering
Android applications are coded in Java and it has the flexibility of reverse engineering its program. It is not difficult to sort and read the code of java application through reverse engineering process. When android application is compiled, the classes and labels are kept there in code. It makes easy to understand what actually the program is executing. Smart enough people are out there who just change the code and enjoy your work.
A number of steps have been taken to stop software copy writing. Google License Verification Library has been introduced to make people pay for the applications they use. People have still found the ways to defeat the code of application.
The Best Solution
The best solution to this problem is Pro-Guard. It is an obfuscating tool making the process of reverse engineering very difficult and thus minimizing the chances of software piracy.
How Pro-Guard Works for Android Applications
Pro-Guard is already integrated with android system, but it is run when application is at release stage. This tool obfuscates and optimizes code of the application by renaming labels, classes and eliminating unused commands. It shrinks .apk file making reverse engineering more difficult.
When a java source file is compiled, then there are two steps. First it is converted into Java bytecodes. Here we apply Pro-Guard. It impressively obfuscates and compresses code to a reasonable extent. In 2nd step it is converted into Dalvik bytecodes. This is quite useful for the release version of application.
Advantages of Applying Pro-Guard to Android Applications
1. The core advantage and purpose of using pro-guard with android applications is that it protects your application from being copied or used illegally. This is done by obfuscating the code of application.
2. It reduces and compresses the size of java bytecodes up to 30% making file size very less.
3. Reduced file size helps in easy and fast downloading of application for users from internet. Hence, enhancing the features of web application development.
4. Pro-Guard is especially employed when android application contains security features like license verification. Hence making online verification process more secure and authentic.
5. Smart Phones have only limited memory. Small size of android application makes application, start quickly and occupy less phone memory.
