How can I test the presence or absence of sound in Android? For example, turn on the music or the radio and check if there is sound or not.
Try to use Audio manager.

I would like to develop an app with which you can control the focus of individual sound outputs, so that you can, for example, play music with Spotify and at the same time play a video via Youtube, which then no longer has any sound. Is something like that even possible?
Thanks for an answer
I am developing an app with Android Studio 2.1 and I would like to record a video of an usage example, with sound.
I have already recorded some videos, but always without sound. As the sound in my app is a key feature, I would like to have the video with the audio output of my app.
Is it possible? In case it is, how could I use it?
Thanks!
Maybe you should try using external app for recording both screen and sound. I have dig in just few mins and i have found some apps.
Here I left link to a top http://www.androidauthority.com/best-screen-recording-apps-600838/
The last one seems to be the one you are looking for (SCR Screen Recorder, which requires root), hope it works!
Other option could be to use a male to male audio cable and record the audio transmitted to the pc.
I'm trying to design an Android app that will start a service which applies a reverb (using convolution) to any audio played through the phone regardless of the app the audio is coming from. The service would ideally run in the background and enable the reverb effect as soon as audio begins to play on the device.
Is something like this possible on a non rooted Android device, and if it is, where's the best place to get started?
Thanks
It is not possible without root access.
There is some example of real time convolution such as viper4android fx though it uses linux native driver to achive the problem.
I have some sound that plays during a phone call on my app. Its hard to test this on the desktop head unit but i'd like to know on a real device if i simply plug the phone into the car will my audio automatically play to the car speakers ? I notice when i use the DHU that it already sets the phone on speaker so im assuming it routes to the cars speakers but i wanted to make sure.
So to be clear, imagine i have an app that plays music based on some trigger, if i plug the phone into the car and execute that trigger will the audio get routed to the speakers of the car without the app needing to do anything ?
I plugged my phone into my Pioneey NEX head unit and the only audio that came through the head unit was that of the applications that support Android Auto. Any additional sounds (e.g. notifications not associated to an Android Auto application) were played by the phone itself.
Hope this helps.

I am trying to investigate if it is possible to get hold of audio stream on android device (for example android tv) which I can use for some purpose from inside my app (my app can be system app). Lets say something is playing on an android device (it could be anything that use the audio part of an android device). From my application , I would like to intercept the audio stream to analyze it, to record it, etc.
Any advice is appreciated.
