问题 I would like to turn on the speaker and set it to maximum volume. In my PhoneStateListener I'm intercepting the incoming call, and it works fine for any incoming/outgoing call. The thing is that I want to turn on this feature only for two specific incoming numbers.

问题 We're looking to send some serial data out from the headphone jack, but would like to still be able to play audio from the speakers. Is it possible to send output to both? If so, is it possible to send different audio to each? 回答1: Not as far as I'm aware.

问题 I currently have an app that generates sounds on the fly, like pure tones and white noise, and I can hear that on the headphones. Is it possible to send the same signal to the internal speakers and the headphones at the same time? I would like to do this on iOS 7 and KitKat. Probably, Android L and iOS 8 in the future... On iOS I have seen that a new feature was introduced on iOS 6, multiroute, which let select the audio route. The thing is that when I connect the headphones I can not choose

问题 I am currently writing an app that calls for the recording and real time processing of audio data. For this, I am using the AudioRecord class. This works all well and good, except the default setting for recording audio on my primary testing device, a galaxy nexus, is to record from the back speaker.
