Questions about how Android Studio uses code obfuscation!

1. Why do you want to confuse code?
2. Refer to: http://www.cnblogs.com/wangcan/p/3477840.html

1,android Studio 1.3 versions before!

Used to think IntelliJ idea and Android studio in the Proguard-project.txt inside set up, in the compile time directly to the code to confuse, after their own anti-compilation only found, what is confused, there is a operation did not do,

(You'll need to tick the run Proguard on generate signed APK (signature).) ) Focus!! , otherwise copy the code to press generate signed APK button when no effect!

The 1,android Studio 1.3 version does not have generate signed Apk-run proguard this option!

To put the Build.grandleminifyEnabled  改成Ture 就可以了！

minifyenabled < Span class= "KWD" >true 
 
 
 
 Below is the code I used:
