Hotword detection disabled with accessibly service

问题

I've created a accessibly service for saving every toast message, but now hotword detection in Google Now will be disabled, if I activate my service. Logcat shows:

W/HotwordState﹕ suspended: 11001001000000

And on Google Now you can see it with a different mic-icon.

What could cause this behavior?

Edit: The source code is on github now: https://github.com/mars3142/toaster

回答1:

To prevent false positives, hotword detection is disabled when a spoken feedback service is enabled. You have defined your service as providing all possible types of feedback, which includes spoken.

android:accessibilityFeedbackType="feedbackAllMask"

You should change this to reflect only the type of feedback your service actually provides. For example:

android:accessibilityFeedbackType="feedbackGeneric"
