YAIM - Yet Another Image WUT?

Any questions? [email protected]

This application is not an end-to-end solution. I would appreciate any comments about code style.

I wanted to show how I can handle concepts such as:

• MVP architecture, SOLID
• basic of DI and Reactive
• knowledge about modern android tech stack = libraries, tools, patterns

Features:

• can show images from Flickr feed with basic metadata if present
• can refresh
• offline - nothing happens

Libs

• LeakCanary 1.5 - to track and deal with memory leaks efficiently
• Hugo 1.2.1 - (used during development) - fast and effortless logging mechanism
• Retrofit 2.1.0
• Gson Converter 2.8.0
• RxJava2 2.0.4
• RxAndroid 2.0.1
• RxAdapter 1.0.0
• Dagger2 2.7 - The only choice left. No reflection, fast.
• Retrolambda 3.3.1 - I didn't want to migrate to 1.8 fully and use Jack&Jill toolchain so I used it
• Glide 3.7.0 - recommended by Google, with very nice cache, simple.
• ButterKnife 8.4.0 - "A butter knife is like a dagger only infinitely less sharp." and because Jake did great work.
• Stetho 1.4.2

glide_memory_cache.png attached.

The screenshot is a prove that Glide is caching images. From the 3mimute5s to 3m25s I swyped slowly from top to bottom so images were downloaded one by one. Then I swyped until 3m40s with furious anger up and down and again. No network operations, images were cached at the first step. 3m40s is a feed refresh event. Until 3m45s I was swyping fast throught entire list. It triggered "a lot of" network operation at one time. After 3m45s - again, images are cached, no network operations.
