Streamline releases with Android

When it comes to releasing a build, it usually goes without saying that there are a few housekeeping tasks that need accomplished before an actual release goes out. Things like tagging and pushing you

Customizing EdgeEffect

If there’s one thing Android is good for, it’s being able to customize almost every aspect of your application, down to the nitty gritty. One area that some developers/designers may overlook when customizing is the EdgeEffect. The EdgeEffect is an indicator to let the user know that he/she have reached the end of the scrolling container. You’ll also know it as the blue overscroll glow…

Managing Fragment States Manually

Notifying ViewPager Fragments

As the title suggests, this post is about notifying Fragments in a ViewPager. Even though PagerAdapter has a notifyDataSetChanged() method, this method is for a different purpose.

Using Custom ActionBar Title Views

The ProblemThe default ActionBar is good for most use cases, however some applications may require further customization to establish a brand.

The getItem(int) method gets called by instantiateItem(ViewGroup, int) if the Fragment at the given position doesn’t exist already in the FragmentManager. This explains why getItem(int) returns a new instance every time it’s called in the snippet above.
