To suppress this warning, remove "buildToolsVersion '25.0.0'" from your build.gradle file, as each version of the Android Gradle Plugin now has a default version of the build tools.

@rclai I think the issue you're seeing here is that this now refers to a ReactNativeHost class. You should see this error disappear if you call this.getApplication().

protected List<ReactPackage> getPackages() {
  return Arrays.<ReactPackage>asList(
    new KeyboardInputPackage(this.getApplication()) // (this = Android application object)
  );
}
