AndroidUtilCode

AndroidUtilCode bundles the kind of Android helper functions developers end up rewriting anyway. The README splits the library into a main module and a rarely used one, and ships demos with unit tests.

The library splits into utilcode, for the utilities used in everyday development, and subutil, for the ones that come up less often but can still simplify the main module. The README frames both as a way to cut repeated boilerplate and raise development speed. Written in Java under Apache-2.0.

Each utility is supposed to come with a complete demo and a unit test, which makes the collection usable as a reference while you learn the API rather than just a pile of copy paste helpers. A badge in the README points to API level 14 and up as the supported baseline. Both modules carry the same testing expectation, which is what makes the whole thing feel maintained rather than abandoned.

There is a donation section with a QR code for anyone who wants to support development, plus contact channels running through a blog, Jianshu, Weibo, and a QQ group. The README itself mixes English and Chinese, which hints at where most of the community sits and how the project has been run since 2016.

A long lived Android library with a simple pitch: common helpers, tested, and collected in one place. The description still carries an updating tag, suggesting the author keeps adding to it. For a project of this age, the biggest question is whether the demos and tests have kept pace with the APIs, which the README does not say one way or the other. The donation and contact links suggest a single maintainer running a community around it, which matches how the README reads.
