Open Source Android Search Apps

KISS (Keep It Simple and Stupid) is a blazingly fast yet incredibly small launcher for Android that requires nearly no memory to run. It expedites searching through the apps, contacts and settings of your Android device, giving you just one simple interface to find everything you need fast. No need to skim through dozens of other apps just to find one-- simply enter a few characters and hit enter. Need to make a call? Just enter the first three letters of the contact's name and hit the phone button. No more time and effort is wasted on searching, and you won't have to look at long lists of contacts or a grid of application icons doing absolutely nothing. KISS is smart and gets smarter as you keep using it, remembering your most commonly accessed search results.

PersistentSearch is an open-source Android UI library that recreates the persistent search bar found in older Google Now, Google Maps, and Google Play interfaces. It allows developers to integrate a familiar search component directly into application layouts. The library provides an expandable search field with customizable branding and interactive search suggestions. Developers can populate suggested results with titles and accompanying icons. Built-in listeners report search queries, text changes, result selections, and search field interactions. It also supports voice recognition through Android's speech recognition interface. Additional methods allow search interfaces to open from toolbar menu items and customize elements such as logo text colors. PersistentSearch can be integrated into Android Studio or Eclipse projects, although development has been formally discontinued.
