This is the list of errors that I get when I try to export my Android app with ProGuard enabled. A little bit of Googling and I found that I need to add jar files to the proguard-project.txt. So far what I have added looks like this (but to no avail):

-keepattributes SourceFile,LineNumberTable -keep class com.parse.*{ *; } -libraryjars \libs\Parse-1.5.1.jar -keepclasseswithmembernames class * {     native <methods>; }   

I also have 3 more libraries along with Parse namely Crashlytics, Picasso and V4 Support.

Answer 1

Made a few changes to proguard-project.txt file (if you have more than one module in your project - put it in the module which calls the *.jar file you are getting warned about):

-keepattributes SourceFile,LineNumberTable -keep class com.parse.*{ *; } -dontwarn com.parse.** -dontwarn com.squareup.picasso.** -keepclasseswithmembernames class * {     native <methods>; }   

The -dontwarn lines were needed. Basically what they tell ProGuard is that these jars work fine on their own so don't complain when you cannot find the classes they reference.
