android-gif-drawable
Views and drawable for displaying animated GIFs on Android
Bundled GIFLib via JNI is used to render frames. This way should be more efficient than WebView or Movie classes. Current development builds (build from dev branch) are published to OSS snapshot repository. To use them, specify repository URL in repositories block. For Android 4.2+ (API level 17+). Supports GifTextureView hardware-accelerated rendering, and GifTexImage2D OpenGL ES 2.0+. See sample directory. Sample project is under construction. Not all features are covered yet. The simplest way is to use GifImageView (or GifImageButton) like a normal ImageView. If drawables declared by android:src and/or android:background are GIF files then they will be automatically recognized as GifDrawables and animated. If given drawable is not a GIF then mentioned Views work like plain ImageView and ImageButton. GifTextView allows you to use GIFs as compound drawables and background. -

appcrawler
Automated mobile app crawler and testing tool built on Appium
AppCrawler is an automated mobile application testing tool designed to explore and interact with app user interfaces automatically. Built on top of the Appium automation framework, it systematically crawls through application screens and performs actions such as clicking buttons, navigating menus, and interacting with UI elements to simulate user behavior. It is commonly used for automated functional testing, UI exploration, and detecting crashes or unexpected behaviors in mobile applications. AppCrawler works by traversing the interface structure of an application and executing predefined or dynamically discovered actions on clickable components. Its behavior can be customized using configuration files that define traversal rules, element selection logic, and specific actions triggered by conditions encountered during testing. AppCrawler supports rule-based filtering such as blacklists and whitelists to control which elements are explored and which are ignored. -

greenDAO
Light ORM solution for Android that maps objects to SQLite databases
Android ORM for your SQLite database. For new apps we recommend ObjectBox, a new object-oriented database that is much faster than SQLite and easier to use. For existing apps based on greenDAO we offer DaoCompat for an easy switch (see also the announcement). greenDAO is an open source Android ORM making development for SQLite databases fun again. It relieves developers from dealing with low-level database requirements while saving development time. SQLite is an awesome embedded relational database. Still, writing SQL and parsing query results are quite tedious and time-consuming tasks. greenDAO frees you from these by mapping Java objects to database tables (called ORM, “object/relational mapping”). This way you can store, update, delete, and query for Java objects using a simple object oriented API. We want to provide the fastest Android ORM. -
