Local Broadcast is not receiving broadcast

Question

This is how I'm sending broadcast

if (isPlaying) {
                val intent = Intent(MUSIC_REQUEST)
                intent.action = PAUSE
                requireContext().sendBroadcast(intent)
                binding.playSong.setImageResource(R.drawable.ic_play_icn)
            } else {
                val intent = Intent(MUSIC_REQUEST)
                intent.action = PLAY
                requireContext().sendBroadcast(intent)
                binding.playSong.setImageResource(R.drawable.ic_pause_icn)
            }

And this is how I'm receiving Broadcast

when (intent!!.action) {
                PAUSE -> {
                    if (mediaPlayer!!.isPlaying) {
                        Log.i(TAG, "onReceive: paused Received")
                        mediaPlayer!!.pause()
                        isPlaying = false
                        val pI = Intent(MUSIC_REQUEST)
                        pI.action = PAUSE_REQUEST_COMPLETED
                        sendBroadcast(pI)

                    }
                }
                PLAY -> {
                    isPlaying = true
                    Log.i(TAG, "onReceive: play Received")
                    mediaPlayer!!.start()
                    val pI = Intent(MUSIC_REQUEST)
                    pI.action = PLAY_REQUEST_COMPLETED
                    sendBroadcast(pI)
                }

This is how I'm registering it in on create of service

LocalBroadcastManager.getInstance(this).registerReceiver(receiver, IntentFilter())

but at receiving end I'm unable to receive intent. Kindly guide me what could be possible error

@Nitish for now can you please guide me how to use this broadcast? — Muhammad Sajid, Jan 04 '22 at 05:19
I haven't used local broadcast in long time, but as far as I remember there should be event name in `IntentFilter()` , othervise how will broadcast will know for which on event it's register.

Broadcasts sent via requireContext().sendBroadcast(intent) are not local broadcasts

You need to use LocalBroadcastManager for the sending as well.

LocalBroadcastManager.getInstance(this).sendBroadcast(intent)

register receiver like this:

val intentFilter = IntentFilter()
filter.addAction(PAUSE)
filter.addAction(PLAY)
context.registerReceiver(receiver, intentFilter)

or this: add the filter to your receiver, in AndroidManifest.xml

<intent-filter>
    <action android:name="PAUSE" />
</intent-filter>
<intent-filter>
    <action android:name="PLAY" />
</intent-filter>

I'm using local broadcast and I think no need for declaring in manifest – Muhammad Sajid Jan 04 '22 at 05:57
@Muhammad Sajid Yes. Dynamic registration is enough. Check your action name . Use your package name or something you like as prefix, e.g. ```const PLAY = "${BuildConfig.APPLICATION_ID}.action.PLAY"```. – Krahmal Jan 04 '22 at 06:06
