Why would anyone build with this?

REASON 1

Show reliable confirmation or error pop-up messages in an Android app without crashes or silent failures.

REASON 2

Set up custom pop-up styles once and reuse them throughout your app with a single line of code.

REASON 3

Trace exactly which file and line of code triggered a toast to speed up debugging.

REASON 4

Display pop-up messages correctly even when your app is in the background on Android 11.

Wtf does this do

Toaster is an Android library that fixes the frustrating problems developers run into when showing small, temporary pop-up messages called "toasts." If you have ever built an Android app and noticed your little confirmation messages crashing, failing to show up, or getting blocked by system settings, this tool is designed to solve all of those headaches. The built-in Android toast system is notoriously fragile. It can crash on Android 7.1, get silently blocked if a user disables notification permissions, and stop working in the background on Android 11. Toaster works around these issues by acting as a smart wrapper. If an app is in the foreground, it bypasses the normal system and displays the message directly. If the app is in the background, it falls back to the system's default method so the message still appears. It also handles technical edge cases by intercepting and capturing system errors that would normally cause the app to crash. An Android developer would use this to save time and avoid debugging obscure system errors. For example, if an app shows a server error message to a user, debugging where that message came from can be difficult. Toaster logs the exact file and line of code that triggered the pop-up, making it easy to trace. It also lets developers set up custom pop-up styles once, and then use them everywhere in the app with a single line of code. What stands out about this project is its focus on compatibility and size. At just 34 KB, it is much smaller than similar libraries. The README also notes it was the first library of its kind to adapt to Android 11's strict background display rules, doing so by smartly switching to a standard system style when an app is backgrounded to ensure the message still appears without violating the new OS restrictions.

Yoink these prompts

Prompt 1
Add the Toaster Android library to my project and replace all my Android Toast.makeText calls so pop-up messages stop crashing on Android 7.1 and later.
Prompt 2
Help me set up a custom toast style with Toaster and call it from anywhere in my app with a single line of code.
Prompt 3
Configure Toaster so that when my app is in the foreground it shows a custom-styled pop-up, and when it is backgrounded it falls back to the system default style for Android 11 compatibility.
Prompt 4
Show me how to use Toaster's logging feature to trace which file and line of code triggered a toast popup in my Android app.
