Answer 1

Yes, this issue seems to have been reported on the official bug tracker for Android.

I am developing an App which uses the official Consumer IR API introduced in Android 4.4 KitKat. Since the Lollipop rollouts for popular devices like the HTC One M8 or Samsung Galaxy S5 I am getting many reports from users of said devices that my App is not working on Lollipop. I do not own a Lollipop device myself, but I borrowed an M8 and did some tests.

It seems like the method ConsumerIrManager.transmit() is a no-op on Lollipop. No matter was pattern is given, it returns instantly.

Before discovering that Galaxy S5 users have the same problem, I contacted the HTC support on that matter and was told to contact the Google support.

It would seem S5 devices are getting the same issue as well, although it's hard to tell because developers are getting contradictory reports from S5 owners.

Here is an HTC-only fix that someone found for his M7 after it stopped working because of a Lollipop update. He basically reverted to an earlier version of the IR HTC API before they had switched to the official Google's api.

Otherwise, you should star the issue on the bug tracker, and perhaps point your own users to do the same. The more people star this issue, the higher priority it will be given.
