I think it s not possible  Though I found an app from google play called PHONE MUSIC which claims to    Thus whenver someone puts you on hold just hit the hovering musical note and start playing music  Or play music while someones on the phone with you

I think this is possible in one case 1 Some of the native music players in android device where handling this they  restrict the music when call is in TelephonyManager EXTRA STATE OFFHOOK  OFFHOOK STATE  so there is no way of playing the background music using native players and some other players like  quot poweramp music palyer quot  2 By using the MediaPlayer class also it is not possible clearly mentioned in documentation  3 It is possible only in one case if your developing custom music player with out using MediaPlayer class  in that implements AudioManager OnAudioFocusChangeListener by using this you can get the state of the audiomanager in the below code  quot focusChange AUDIOFOCUS LOSS TRANSIENT quot  this state calls when music is playing in background any incoming call came  this state is completely in developers hand whether to play or pause the music  As according to your requriment as for question you asked if you want to play the music when call is in OFFHOOK STATE dont pause playing music in OFFHOOK STATE  And this is only possible when headset is disabled AudioManager am    AudioManager  this getSystemService Context AUDIO SERVICE             OnAudioFocusChangeListener afChangeListener   new OnAudioFocusChangeListener             public void onAudioFocusChange int focusChange                if  focusChange    AUDIOFOCUS LOSS TRANSIENT                    Pause playback  during incoming call                 else if  focusChange    AudioManager AUDIOFOCUS GAIN                       Resume playback  incoming call ends                else if  focusChange    AudioManager AUDIOFOCUS LOSS                    am unregisterMediaButtonEventReceiver RemoteControlReceiver                   am abandonAudioFocus afChangeListener                      Stop playback  when any other app playing music  in that situation current app stop the audio

Two answers  both valid  depending on how sloppy you like to be   1  No  it s not currently possible to inject audio into a phone conversation   2  Yes  it s possible   It s also an ugly  ugly kludge   Turn on the hands free function of your phone   Create a media player  set the media source  set the volume to 1 0f  highest  and call player start     If the microphone and speakers on the phone are of reasonable quality  the other party to the call will hear the music   He or she will also continue to hear anything you say  as well as ambient and other sounds in your immediate vicinity

Note  You can play back the audio data only to the standard output device  Currently  that is the mobile device speaker or a Bluetooth headset  You  cannot play sound files in the conversation audio during a call   See official link    http   developer android com guide topics media mediaplayer html

No  It is not possible  But if you want to dig it more  then you can visit Using Android phone as GSM Gateway for VoIP where author has concluded that      It s not possible to use Android as a GSM Gateway in its current form  Even after flashing custom ROM because they also depends on proprietary RIL  Radio Interface Layer  firmwares  Hurdles 1 and 2  API limitation  can be removed because the source code is available for the open source community to make it possible  However  the hurdle 3  proprietary RIL  is dependent on the hardware vendors  Hardware vendors do not usually make their device drivers code available

You failed to find an app that does this because it is not possible   The documentation clearly states  here       Note  You can play back the audio data only to the standard output   device  Currently  that is the mobile device speaker or a Bluetooth   headset  You cannot play sound files in the conversation audio during   a call    The reason behind this decision has probably something to do with security  there are several scenarios where this capability could be used for cons     the OP is highly similar to this  hence I m basically giving the same answer
