Add dagger support

[Calinoiu Alexandru Nicolae]

Hi,

Any luck with http://square.github.io/dagger/ ?

Here is what I use for dagger 1.2.1. Reportedly Dagger 2.0 (yet to be released) does not need any rules at all:

-keepclassmembers,allowobfuscation class * {
    @javax.inject.* *;
    @dagger.* *;
    <init>();
}

-keep class javax.inject.** { *; }
-keep class **$$ModuleAdapter
-keep class **$$InjectAdapter
-keep class **$$StaticInjection
-keep class dagger.** { *; }

-dontwarn dagger.internal.codegen.*

@dalewking thanks, do you want to add that as a pull request? If not, I can take care of it, but I always like having more contributors.

Wait for now, as this is still not working completely yet

[Dallas Gutauckis]

To the best of my knowledge there is no concrete solution due to how Dagger builds the graph/configuration. One has to provide explicit -keepnames entries for anything any module @Provides.

This worked for me

-keep class dagger.** { *; }
-keepclassmembers,allowobfuscation class * {
    @javax.inject.* *;
    @dagger.* *;
    <init>();
}
-keep class **$$ModuleAdapter
-keep class **$$InjectAdapter
-keep class **$$StaticInjection
-keep class javax.inject.** { *; }
-dontwarn dagger.internal.codegen.**
-dontwarn dagger.producers.internal.**
-dontwarn dagger.shaded.auto.common.**

I added a Dagger config from another PR. See https://github.com/krschultz/android-proguard-snippets/blob/master/libraries/proguard-square-dagger.pro. If that doesn't work we can revise it, but it was fairly close to what @ivazhnov suggested so worth a shot.
