This is a collection of Android projects that I maintain mainly for personal use for remembering some technique or code usage guideline. It is basically a collection of samples.

Some of the sample projects in this repository were obtained from third parties and adjusted to my needs. For those projects the original license was maintained and mentioned in the proper project README.

Modularization is an architectural strategy utilized to improve the maintainability of a software project, specially when a project starts to grow larger or if there are more than one team involved in parts of its development.

• Modularized Sample App - A sample on how to create a modularized project for an Android app using the Version Catalog and Convention Plugins features of the Gradle build automation tool

Flavors are used to provide different "flavors" of the same app. A good example is a "free" and a "pro" version of the same app.

• Buy Me a Drink App - A Sample on how to create an App with "free" and "pro" versions by using the flavors configurations. The free versions has adds banners while the pro version is adds free and also has a premium functionality that is not available on the free version.

• Using Hilt in your Android app Codelab - LoggingApp - Hilt is a dependency injection library for Android that reduces the boilerplate of doing manual dependency injection on an Android project. It is built on top of the popular DI library Dagger. This app is the result of my implementation of this Codelab.
