Better Presentations From a Service

Back in May, I blogged about how to show a Presentation from a Service. In there, I said that the SYSTEM_ALERT_WINDOW permission was required to make all of this work, because we needed a TYPE_SYSTEM_ALERT Window to display content on an external display from the background.

Clearly, somebody had spiked my chocolate milk while I was working on that bit of the code.

Andrew Hughes pointed out to me that removing TYPE_SYSTEM_ALERT and SYSTEM_ALERT_WINDOW from my code worked just fine. I reproduced his findings and updated my PresentationService to match. And it seems to work fine.

My apologies for my mistake, and many thanks to Andrew for his help!
