Receiving MP3 play actions in a BroadcastReceiver in Android - android

I am trying to build an Android Service that should get notified when the user starts playing an MP3. I checked LogCat when I start playing a song and saw that the following Intent is logged:
Intent { act=com.android.music.PLAYBACK_VIEWER flg=0x4000000 cmp=com.android.music/.MediaPlaybackActivity }
I couldn't figure out how to write an IntentFilter to let my Service know that this event has occurred and let me know the name of the song that will be played. I searched Android reference but could not find anything on PLAYBACK_VIEWER.
Thanks,
C

I would do neither. First, none of this is part of the SDK and so may change at any point. Second, this will only work for the built-in media player application, not any third-party or OEM-supplied media players, and I expect more people to gravitate to those.

MediaStore.Audio.Media.RECORD_SOUND_ACTION not working in nougat

I am using MediaStore.Audio.Media.RECORD_SOUND_ACTION to open sound recorder application, I am not able to open application as no default application present, then i install two voice recorder application even though not able to see these application in my chooser intent. I am using following code-
Intent soundRecorderIntent = new Intent(); // create intent
soundRecorderIntent.setAction(MediaStore.Audio.Media.RECORD_SOUND_ACTION); // set action
startActivityForResult(soundRecorderIntent, ACTIVITY_RECORD_SOUND); // start activity
It works well in marshmallow
The code is correct and you've probably found an app that supports the intent by now. But to prevent that others waste their time like I did, here's a quick note:
Most of the currently top rated voice recording apps in the Play Store do not provide the necessary intent filter.
That seemed so unrealistic to me that I doubted my code when it didn't work after having installed the five most popular voice recording apps. But there's a handy manifest viewer app that reveals that their manifests simply do not declare the intent filter. So, as said, the code is correct.
To save you the time from searching for a suitable app, here are two that are invocable:
Audio Recorder from Sony
Samsung Voice Recorder from Samsung
There is no requirement for a voice recorder app to support this Intent action, and apparently your device does not ship with an app that supports this Intent action either. Your code itself seems fine.
If recording is optional to your app, catch the ActivityNotFoundException and tell the user that they do not have a recorder, and perhaps suggest to them that they install one that you test that works, if you can find one.
Otherwise, record the audio yourself, using MediaRecorder.

Google ChromeCast Playlist from Android Device

I'm using a sample app for the RemotePlaybackClient from #commonsware to play a video from a url to Google ChromeCast dongle, the app works like a charm but I would like to implement a playlist, any idea how to send a playlist to ChromeCast from an Android device?
As usual, I don't need code, just links, tutorials, etc... Tks.
Are you using a custom receiver?
If so, you can pass a json to such receiver with your playlist and manage that list with a playback state.
you might try looking at "mediaList" object here. Thats your playlist object.
This is a totally different project (not mediaRouter api but ccl instead) that i used because i wanted to implement a playlist and wanted to NOT take on my own receiver app. I wanted to see whether the default receiver could collaborate with an existing github sender sample - altered slightly to manipulate both a playList implemented in the "mediaList" AND to send appropriate and successive PLAY instructions to the default recieiver app when that app's state as relayed in normal "consumer" message traffic indicated state=ready.
D/ccl_VideoCastManager(31057): onApplicationStatusChanged() reached: Ready To Cast
So, when the default receiver fires the "ready" message, the senderApp can just call getNext to return an entry from "mediaList" and then send a "play(mediaInfo.entry)" to the default receiver.
onApplicationStatusChanged() is the interface used by the ccl to commmunicate/ sync player state between the local/remote players. When the default-remote-state changes to "ready to cast" you can use "VideoCastManager" and its base class to select the next MediaInfo entry and format a message for the remote to play it...
this.startCastControllerActivity(this.mContext, nextMediaInfo, 0, true);
code above from sender/ccl base tells the receiver to play the item that the sender has determine is next from list.
Note : i was advised to implement the playlist on a custom receiver app that i would write. Im not that ambitious and found a very simple hack on the sender/ccl classes that was reliable enough for me.

How to get active music player -- android

thanks for previous replies,
Is it possible to get package name of active and runningin service(background) music player. I can able to get the music actions(metachage or playstateChange) but when i use intent.getPackagename, im getting null. can anyone guide me on how to get the package name of music player.
Thanks!
Supplying the file URL and open it in browser does not make sense, because this URLs expire after a wile.
No, insofar as there is nothing magic in Android that denotes a "music player" from anything else.

Playing Audio During call so that other person on call can hear it

i am developing one application which
needs to play an audio song to callee when call is lifted by callee,
and automatically call has to be disconnected automatically when audio
song playing completed . i tried to find in android API for any
classes or methods to do this, but failed to find... please help me
how to do this..
your answer could be helpful to me...please do reply
Thank you in advance..
AFAIK, it is not possible to play a sound in the ongoing call and also to automatically dosconnect a call. Telephont API doesnt provide any methods to do any od these. So both od these requirement can't be fullfilled in ANdroid.

How to automatically answer call and play prerecorded sound out to the caller and DTMF on Android

Could it be possible now, which we can develop an Android application having the following requirement for its working steps
Automatic receive the call, then
Play some sound out to the caller, wait for DTMF response, then
Record the caller sound (in the case that they permit, by pressing 1 as DTMF response)
Callee can play back the recoreded sound later.
Thank for all answers in advance .....
Hey I am also making same application...for Automatic receive call you need to change Source Code of android. I have done it successfully with froyo 2.2. There is method answerCall(Phone phone) in PhoneUtils.java file with that you can automatic receive call.
I am also searching for DTMF....but till now i didn't get anything which can be helpful....for DTMF decoding....
the first point seems possible. check the state of call if it is ringing state the program can auto attend it for you..you can find more information in this link.
