Hello, I want to develop an app that it can listen to my voice at any time at any screen. For example, I can say "Hi Buddy", then it can be activated and listen to my words. it is just like "Ok Google".
I'm using a background service to listen on the microphone, onece a keyworkd "Hi Buddy" is detectd, then it will be launched. The current problem is that, there is a race condition of the microphone with Google Now (and other apps like Recorder app). To avoid affecting other apps, I want to release the microphone when Google Now's micophone button on launcher panel is clicked, or it is on the voice input page of Google Now. But I don't know when other apps are attempt to use the microphone, and can't detect wheather Google Now is showing the voice input page or not. So I don't know when to release the microphone. So when I app is running, other apps are not able to use the microphone. I create the AudioRecord with MediaRecorder.AudioSource.VOICE_RECOGNITION. There is another source MediaRecorder.AudioSource.HOTWORD, but it is a hidden audio source and require the permission android.permission.CAPTURE_AUDIO_HOTWORD, I can't get the permission as a non-system app. My questions are: 1. How to detect if other apps trying to use the microphone or not. (or how the get the android.permission.CAPTURE_AUDIO_HOTWORD permission) 2. How to know if Google Now is showing its voice input page or not? 3. Any other workaround? Anyone can help?
