Configure Proguard to Retain line Numbers in Stack traces

When using Proguard for code obfuscation, in order to make it easier to release debug later, you want to keep line number information in the stack record, you can add the following two lines to the Proguard file:

-renamesourcefileattribute sourcefile    
-keepattributes sourcefile,linenumbertable

The "a" ensures that source file names are hidden ('ll is named "SourceFile" in stack traces), the second instruct s Proguard to include the line numbers.
