A twitter search client. User can search for tweets matching their entered search criteria. This app has the following features.

• Prominent text content of tweets
• Support paging of search results.
• Provide search text suggestions based on user's search history
• Links in the content text are made prominent using different text color.
• Links are clickable, and a WebActivity is provided to handle the url.
• The WebActivity have a mechanism to handle no internet situation and support pull to refresh.
• A LaunchActivity that has a flip animation using my own library-FlipView

And for bonus points, this App provides three more additional search functionality.-- Video, Near and Until.

• Video is to search for tweets that have video links.
• Near is to search for tweets that have been tweeted near user's position
• Unitl is to search for tweets published until a certain date.
• Provides a user interface to easliy exploit these functions.

For code structure:

• The App is based on MVP model.
• Using Daggar2 and Rx to achieve Dependency Injection
• Using Fragments and ViewPager so this App is Expandable

Clone the project and sync and build in Android Studio. The Key and Token for Twitter are in gradle.properties which I shouldn't put them there publicly. But for code review and a quick build of the project, I think it's all right to public it for now.

When working on this project, I refered to some code from project SearchTwitter for saving time.
I largely reconstructed the code and added more features.

• When I was working on the project, I find a bug that the fragments get a null context when its wrapper ViewPager is set to Visibility.NONE. So I looked into it. The flow of ViewPage populate fragments is as follows:
  ViewPager : populate() ->
  PagerAdapter : instantiateItem() ->
  FragmentPagerAapter : instantiateItem() ->
  FragmentTransaction : attach() This is where Fragment be attached

So the main problem is that populate is not properly called.

• In normal condition, ie, the visibility is VISIBLE or INVISIBLE. The populate() is called in setOffScreenPageLimit() and onMeasure();
• But when the visibility is set to GONE. the populate will not be called in onMeasure(), so the Fragments are not attached to Activity. So that there Context will be null.
