Android code obfuscation and anti-compilation

Overview:

If you're still a student or have not uploaded apps in the App Store, I'm afraid that's not a deep feeling. In the enterprise, the confusion of Java code is a very important step, from the security point of view, code confusion, it is very important to prevent intentioned people from malicious tampering with the code. The following is the process of code obfuscation and cryptographic signing for Android projects.

steps:

1. Add a file to the project's directory Proguard.cfg

2. Add Proguard.cfg in the Project.Properties file in the project

3. Add in the Proguard.cfg file

-ignorewarnings
-libraryjars Libs/android-support-v4.jar

As follows:

4. Project Right click->export->android->export Android application->next

5.Next after the first step, will enter the KeyStore selection session box, fill in the following information:

6. In the next Key Creation session box, fill in the following format information:

7. Configure your APK file name, last finish

If not unexpected, it will be fun to end up here and get the confusing apk signature file you want to get.

anti-compilation validation:

If it goes smoothly it will be if similar result:

Proguard returned with error code 1. See console:

This problem is caused by code obfuscation and the reference package cannot be found. Just add the following two lines to your proguard.cfg.
-ignorewarnings
-libraryjars Libs/android-support-v4.jar
You can add the required jar based on your project tips.
