I have a app idea in mind, but I haven't been able to figure out one part yet. In Google Now on Android, it gives you the following options to search:
I'd like to know how they made #3 work. I need to have a keyword, that when said, initiates the voice search.
I imagine they have some type of background running service constantly listening for voice actions. Does anyone know how this is achieved?
Here is a image of the Google Now app:
In order to make Android allow apps to run in background, all you need to do is press the open padlock icon right next to them. Once the open padlock changes and you get the “Locked” pop-up notification on your screen, you're all set!
"Allow background activity", under Battery, refers to whether apps are allowed to run in the background (when you're not using them onscreen, or the app is not visible to you) or not.
You can write a service and then use createSpeechRecognizer
in that service. For a complete service code for this you can find the answer at Android Speech Recognition as a service on Android 4.1 & 4.2
