Is there a way to prevent stopping the audio in Spark AR on recording without disable the microphone?

In my current project I have an Audio file which plays all the time. As soon as I click the record button the audio stops. When I disable the microphone it works but I actually want to record my own voice (like a karaoke) This Problem only occurs only on Android.
Is there any hack to fix this Problem?

Just worked on a filter where I had to build a karaoke style gameplay, what I noticed was Spark does not like playing audio AND recording on mic as it probably causes weird artifacting if not implemented properly. It seems like something that will be added line.
Possible fixes to get your filter working for now, add instructions to use the filter with headphones, connecting to an external audio device will let you play audio and record using the mic at the same time. This works on android, not on iOS. You have to give players visual cues to sing along or whatever your objective maybe.
Hope this is sorted out and fixed in the coming updates, really handicaps the kind of experiences possible on the platform.
Hope this helped.

Android - detect if speakers are playing audio programmatically

I'm working on a diagnosis app for android, I want to test whether the speakers are working fine or not. I thought the way to do this is to play a sound and check whether the speakers are playing the audio or not. I looked for code but didn't find anything useful. How can this be achieved in android? Is there a better way to do the same thing?

hey can anybody please tel me that can i access a mic and earphone of my android cell,as we can access camera hardware of cellphone so is there any way to access them as i want to make a walky-talky app.And im a very beginner so please help me out thanks evry1.

You can use AudioRecord to record the audio.
Check some Android audio chat (SIP) projects to how they have done it:

Well that would be android.media.AudioRecord for the mic and android.media.AudioTrack for the sound. But what you want to do won't be something for beginner. You should at least be able to find this in the android api.
I suggest you to start with a less complex program. On the android developer site, you will find a good start for this.

How to make android phone ring?

I would like to make a android phone ring through code.
For example a app installed and the use recieves a call a app listens for this. If a certain number calls then a specific ringtone plays. How do i go about make code to make a android phone ring?

Well first of all i thought it was a good question but apparently people dont understand what you are asking. I think that you want to like call the phone you are calling from or somthing like that, i dont know it is possible but heres the tutorial on phone calls, from the official android website:
http://developer.android.com/guide/topics/network/sip.html

A ring is simply a sound file played through the speaker. Read up on how to configure your mediaplayer object to play your required sound through the external speaker.

This is part of the functionality of android anyway! I am positive that this is not possible to do with an android app without modifying the os. Apps cannot initiate incoming calls for security reasons.
