We made the core library smaller by making things like GIF support optional.

Because of that we have to manually opt-in for gif support in Android. Add both of the following lines to your android/app/build.gradle file under dependencies:

compile "com.facebook.fresco:animated-gif:1.3.0"
compile "com.facebook.fresco:animated-base-support:1.3.0"

So your dependencies section might look like this:

dependencies {
  compile fileTree(dir: "libs", include: ["*.jar"])
  compile "com.android.support:appcompat-v7:23.0.1"
  compile "com.facebook.react:react-native:+"  // From node_modules
  compile "com.facebook.fresco:animated-gif:1.3.0"
  compile "com.facebook.fresco:animated-base-support:1.3.0"

This solves the problem for your debug build but if you want to solve it also in your release build at them moment you have to add the following line to your proguard-rules file:

-keep class com.facebook.imagepipeline.animated.factory.AnimatedFactoryImpl { public AnimatedFactoryImpl(com.facebook.imagepipeline.bitmaps.PlatformBitmapFactory, com.facebook.imagepipeline.core.ExecutorSupplier); }

This was fixed with this commit and will be included in the next release.
