This lightweight library provides visual alerts to developers and QA when an issue happens during development / testing phase.

In traditional android development, when an issue occurs, we use logs to dump the unexpected state or exception trace. Printing to logcat is not enough at times as:

  • Logs can be overlooked by developers if we are not constantly monitoring.
  • Logs maybe on a remote device which is inaccessible.

Using this library, you can provide visual warning to the developer / QA when something goes wrong on your test or internal builds so that critical issues can be highlighted as and when they happen.
