    BasePopup

    BasePopup

    Create a universal and convenient PopupWindow popup library

    BasePopup is a popup library that encapsulates and improves the system PopupWindow. It is a basic library class with a very high degree of freedom and rich API. You can easily complete various popups under the framework of BasePopup. Switching between Release and Snapshot versions may cause Build to fail. At this time, you can clean the Project. QuickPopup adds new APIs and modifies the implementation of QuickPopupConfig to make the code cleaner and cleaner. In response to historical issues, we have unified the role of the root layout margin under match_parent and wrap_content this time. Now the role is consistent with the system and used as margin instead of offset.

    BlurKit

    BlurKit

    The missing Android blurring library

    The missing Android blurring library. Fast blur-behind layout that parallels iOS. BlurKit is an extraordinarily easy-to-use and performant utility to render real-time blur effects in Android. BlurKit is faster than other blurring libraries due to a number of bitmap retrieval and drawing optimizations. We've been logging benchmarks for the basic high-intensity tasks for a 300dp x 100dp BlurView.

    ButterKnife

    ButterKnife

    Bind Android views and callbacks to fields and methods

    ButterKnife is an annotation-based view binding library for Android that reduces boilerplate in Activities, Fragments, and custom views. Developers replace repetitive findViewById calls with BindView fields and define UI event handlers using annotations like @OnClick, with the library generating efficient binding code at compile time. Because it relies on annotation processing, there’s no reflection at runtime, keeping startup paths lean and predictable. The generated bind/unbind lifecycle helps avoid memory leaks by clearing references when views are destroyed. Butter Knife made UI code more readable and maintainable for years, especially in large codebases with complex layouts and many event hooks. While newer Android APIs now offer official view binding alternatives, the project remains a landmark example of how code generation can simplify everyday Android development.

    CMIS Input plugin for Pentaho

    CMIS Input plugin for Pentaho

    Allows querying Content Management Systems that use the CMIS.

    Imagine being able to extract from your Enterprise Content Management System, all the metadata of your documents using simple queries with a query language very close to the traditional SQL. Imagine using the information extracted for statistical purposes, for creating reports and, more generally, to analyse your document archives in a way unthinkable until now with the current tools available. All this is possible within the Pentaho Suite, the Open Source Business Intelligence platform, which is useful to the extraction and analysis of structured and semi-structured data. With this goal (the extraction and analysis of data) has been designed and developed the CMIS Input plugin for Pentaho Data Integration (Kettle) that allows querying Content Management Systems that use the CMIS interoperability standard. The data, once extracted, can be stored and analyzed and perhaps presented in customized reports be published in various formats for the end user (PDF, Excel, etc..).
