Run time Error gradle minifyEnabled true

[unxavi]

Hi mate,

Thanks a lot for the lib, is great and pretty simple. I love it. But I am finding a problem that i am not sure how to solve.

When I build my app with gradle "minifyEnabled true" it's fine, but when I use your lib, the app freezes in runtime when I call in the code

requestFactory.buildListRequest from the class RequestFactoryImpl

When working with retrofit or many other libraries, their documentation comes with information on how to set up the proguard-rules file with their lib.

Do you have any info on this? If I build my app with minifyEnabled true and debuggable true, but of course, no obfuscation is taking place

[AlexGilleran]

Can't say it's come up before - I'll put it on the TODO list, but for now maybe just try retrofit's list applied to the icesoap package?

Something like:

-dontwarn com.alexgilleran.icesoap.**
-keep class com.alexgilleran.icesoap.** { *; }
-keepattributes Signature
-keepattributes Exceptions
-keepattributes *Annotation*

Hi Mate,

Thanks for the quick answer.

Well, first when I do the minifyEnable true, I have to keep this classes in order to compile:

-keep class org.dom4j.* { ; }
-dontwarn org.dom4j.
-keep class org.jdom.* { ; }
-dontwarn org.jdom.
-keep class nu.xom.* { ; }
-dontwarn nu.xom.
-keep class org.w3c.dom.** { ; }
-dontwarn org.w3c.dom.

because if I dont do, when minify it says it will lose references.

No I have add what you said in the last post, and it looks better, but I get this execption

Is it possible that you use reflection in the library and the gradle minify just takes out some classes that you need?

Thanks a lot

[unxavi]

Hi,

I made it work, but I had to add a lot of things, I think I am doing something wrong.

For the proguard rules I added

`-dontwarn com.alexgilleran.icesoap.**
-keep class com.alexgilleran.icesoap.** { ; }
-keepattributes Signature
-keepattributes Exceptions
-keepattributes *Annotation

-keep class org.dom4j.* { ; }
-dontwarn org.dom4j.
-keepattributes Signature
-keepattributes Exceptions
-keepattributes Annotation

-keep class org.jdom.* { ; }
-dontwarn org.jdom.
-keepattributes Signature
-keepattributes Exceptions
-keepattributes Annotation

-keep class nu.xom.* { ; }
-dontwarn nu.xom.
-keepattributes Signature
-keepattributes Exceptions
-keepattributes Annotation

-keep class org.w3c.dom.** { ; }
-dontwarn org.w3c.dom.
-keepattributes Signature
-keepattributes Exceptions
-keepattributes Annotation

-keep class org.jaxen.saxpath.base.** { ; }
-dontwarn org.jaxen.saxpath.base.
-keepattributes Signature
-keepattributes Exceptions
-keepattributes Annotation`

Maybe I can take out some of the keepattributes, but the keep I think thery are needed.

[AlexGilleran]

Yeah you'll probably need at least the keep class for Jaxen as evidently it uses Class.forName somewhere.

I'm pretty sure the keepattributes lines only need to be specified once in the whole file though rather than once for each keep class ?
