@ContentView and Proguard

[thierryd]

Hi all,
I can't make @ContentView works when I use Proguard on my app.

For example:
@ContentView(R.layout.activity_foo)
public class Foo extends Activity {
}

Works during development, but as soon as I package my app for release,
the layout in empty. Furthermore, any @InjectView returns null.

I tried setting in "proguard.cfg":
-keepattributes **

Without success. I even see in the proguard log:
+ Runtime visible annotations attribute:
+ Annotation [Lroboguice/inject/ContentView;]:
+ Constant element value [value '73']
+ Integer [2130903067]

So it looks like proguard modifies the @ContentView annotation and the
result does not work. Any suggestions?

I had the same problem. I found that disabling a few optimizations fixes
the problem:

-optimizations
!code/simplification/arithmetic,!code/allocation/variable,!field/*,!class/merging/*

Specifically, !code/allocation/variable and !field/* fixed this particular
problem. !class/merging/* fixed a problem where dex would error out with
an invalid opcode error in the Android support v4 library.

It doesn't work for me. I tried with

-optimizations
!code/simplification/arithmetic,!code/allocation/variable,!field/*,!class/merging/*

and 

-keepattributes ** 

But my first loaded layout fails on a null pointer exception when using the first reference of the first view.

Am I the only one to face this problem ?

Could you publish more of your proguard files please ?

Thx

But this worked :

-keepattributes *Annotation*,Signature  

-keep class com.google.inject.Binder    

-keep public class com.google.inject.Inject

 # keeps all fields and Constructors with @Inject

-keepclassmembers,allowobfuscation class * {

    @com.google.inject.Inject <fields>;

    @com.google.inject.Inject <init>(...);

Optimizations are very hard to get working. I would try without as a
first step..
