I want to try to make an Android alarm app that is impossible to stop. In other words, it keeps going for a predetermined amount of time, even if the user presses the power button, tries to reduce the volume, or anything else. It does not seem feasible to me, but since I have very little Android experience, I'd like to know if something like that is theoretically able to be done. Thanks.

This question has been addressed on SO here: Override Power button just like Home button .

There are several answers in the link that will give you options and get you 90% of the way there, but no answer will cover all devices/scenarios. The accepted answer in the link puts it best:

The Android system, as far as is documented, defines (a physical button press) as a broadcast action. Following the publish-subscribe pattern of message propagation, this message will notify all concerned parties of this action. Because this message is sent by the system, because the message stack is managed by the system, and because the message is also received by the system, your code simply (cannot be) injected in the right place to block the reception of this message.
