Try to stop a Thread in Android

README.md

Approach with ExecutorService and Future.get(timeout)

Result Future throws exception to the caller, not to an Executor. while (true) { } continues to work.

"методом submit(Runnable) у ExecutedService получить Future и вызвать get c передачей максимального времени ожидания. Это все в try catch. То есть изначально стартовать с таймаутом."
