What do people build with it?

USE CASE 1

Browse the source code as a working Android MVP architecture example with news, images, video, music, and QR scanning.

USE CASE 2

Reference the custom QR scanner module that compares ZXing and ZBar decoding engines side by side.

USE CASE 3

Use sections of the code as a starting point for individual Android features like waterfall image grids or turntable music UI.

So what is it?

SimplifyReader is an Android app built in Java, designed to be a clean, multi-function reader following Google's Material Design visual style. It was written around 2015 and the author notes upfront that many of the third-party libraries it depends on have since been updated, which means it may not compile or run without some effort. The code is shared as a reference rather than an actively maintained product. The app has five sections. The first is a news reader that pulls article lists and detail pages from a news API and displays them in a scrolling list with a web view for full articles. The second is an image browser that queries a search API and displays results in a waterfall-style grid, with support for pinch-to-zoom and smooth transition animations between the list and detail views. The third is a video player section built around a third-party SDK, where passing a video ID is enough to start playback. The fourth is a lightweight music player with a custom turntable-style UI, pulling track data from a music platform's API. The fifth is a QR code scanner the author built as a custom library using two open-source decoding engines, after testing both, the author recommends ZXing for decoding due to fewer false reads, despite ZBar being faster. The project uses an MVP architecture, which is a way of organizing Android code that separates the display logic from the data-fetching logic. The author describes it as an exploratory project and acknowledges that the implementation may not follow every best practice. All included third-party libraries are Apache 2.0 licensed. The project itself is also Apache 2.0 licensed.

Copy-paste prompts

Prompt 1
I have the SimplifyReader Android source code. Explain how the MVP pattern separates the news reader's presenter from its view layer.
Prompt 2
Using SimplifyReader as a reference, help me add a new content section to the app that follows the same MVP architecture.
Prompt 3
In SimplifyReader's QR scanner, the author chose ZXing over ZBar for accuracy. Show me how to swap the decoding engine in that module.
Prompt 4
Help me recreate SimplifyReader's image browser in a new Android project: waterfall grid, pinch-to-zoom, and smooth list-to-detail transitions.
