MacroDroid is the one that's easiest to use, among the powerful ones. Tasker has more power for detailed functions but the interface is hell. Or, if you want free, I always suggest Automagic, from automagic4android.com. It has the best interface and is more powerful than MacroDroid, but the dev gave up on it and decided to give it away. If you try that, you'll have to use version 1.37 (unless you're using android... Source: about 1 year ago

MD has a free version limited to 5 macros, with unobtrusive ads. If you want free, then try Automagic, free from automagic4android.com as abandonware, but you'll have to use version 1.37 if you're using Android 12 or above. Source: over 1 year ago

Automagic is still available from the website, for free. automagic4android.com. If you have android 12 or 13, you will need to get version 1.37, not the latest one. Thanks to goolag. Source: over 1 year ago

One more thing: If you don't use them already, you might look into some automation apps. My top rec. For new users is MacroDroid. It's basically straightforward scripting, and easy to learn. Some people hate the idea of trackers, and MD has quite a few, because the base version is free. Tasker is also scripting but the interface was very badly designed and it's more complex, and seems to have more quirks (like you... Source: over 1 year ago

If it were me, I'd install Automagic (free now from automagic4android.com) and use the overlay feature available in the "Control UI" action, and see if those things are something that can perform functions. You might be able to figure out what app it's from by that. You may have to enable extra permissions for it using ADB in order for that to work, but there are tutorials for that all over the place, and it's... Source: over 1 year ago

RE: HTTP/Web Sockets/TCP/UDP/etc. - check out NineNines libraries: Ranch (TCP Socket Acceptor), Cowboy (HTTP Server), Gun (HTTP client), and CowLib (General HTTP/SPDY library) are pretty good from what I hear. Source: over 2 years ago

Ranch is a pretty well optimized and battle hardened tcp acceptor. It powers the Cowboy/Phoenix server which scales to extreme level of concurrency and low latency. Cowboy uses ranch to pool and accept connections and I believe it uses {active,once}. https://github.com/ninenines/cowboy https://github.com/ninenines/ranch. - Source: Hacker News / over 2 years ago
