Example ProGuard config for a project using RxJava, Guava and Gson

proguard-project.txt

# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in ${sdk.dir}/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the ProGuard
# include property in project.properties.
#
# For more details, see

# Use unique member names to make stack trace reading easier
-useuniqueclassmembernames

# Some libs use annotations like javax.annotation.Nullable which are not available in Android runtime.
# However, that does not matter, so just mute warnings:

# For Guava:
-dontwarn javax.annotation.**
-dontwarn javax.inject.**
-dontwarn sun.misc.Unsafe

# For RxJava:
-dontwarn org.mockito.**
-dontwarn org.junit.**
-dontwarn org.robolectric.**

##---------------Begin: proguard configuration for Gson  ----------
# Adapted from https://code.google.com/p/google-gson/source/browse/trunk/examples/android-proguard-example/proguard.cfg
#
# Gson uses generic type information stored in a class file when working with fields. Proguard
# removes such information by default, so configure it to keep all of it.
-keepattributes Signature

# We use Gson's @SerializedName annotation which won't work without this:
-keepattributes *Annotation*

# Gson specific classes
#-keep class sun.misc.Unsafe { *; }
#-keep class com.google.gson.stream.** { *; }

# Classes that will be serialized/deserialized over Gson
# http://stackoverflow.com/a/7112371/56285
-keep class fi.company.project.models.json.** { *; }

##---------------End: proguard configuration for Gson  ----------

# Remove logging calls
-assumenosideeffects class android.util.Log {
    public static boolean isLoggable(java.lang.String, int);
    public static int v(...);
    public static int i(...);
    public static int w(...);
    public static int d(...);
    public static int e(...);
