I'm trying to implement iOS callkit behavior on Android. I'm receiving a push notification from firebase and I want to show "incoming call" screen to the user. To do it I use ConnectionService from android.telecom package and other classes.
Here is my call manager class:
class CallManager(context: Context) {
val telecomManager: TelecomManager
var phoneAccountHandle:PhoneAccountHandle
var context:Context
val number = "3924823202"
init {
telecomManager = context.getSystemService(Context.TELECOM_SERVICE) as TelecomManager
this.context = context
val componentName = ComponentName(this.context, CallConnectionService::class.java)
phoneAccountHandle = PhoneAccountHandle(componentName, "Admin")
val phoneAccount = PhoneAccount.builder(phoneAccountHandle, "Admin").setCapabilities(PhoneAccount.CAPABILITY_SELF_MANAGED).build()
telecomManager.registerPhoneAccount(phoneAccount)
val intent = Intent()
intent.component = ComponentName("com.android.server.telecom", "com.android.server.telecom.settings.EnableAccountPreferenceActivity")
intent.flags = Intent.FLAG_ACTIVITY_CLEAR_TOP
}
@TargetApi(Build.VERSION_CODES.M)
fun startOutgoingCall() {
val extras = Bundle()
extras.putBoolean(TelecomManager.EXTRA_START_CALL_WITH_SPEAKERPHONE, true)
val manager = context.getSystemService(TELECOM_SERVICE) as TelecomManager
val phoneAccountHandle = PhoneAccountHandle(ComponentName(context.packageName, CallConnectionService::class.java!!.getName()), "estosConnectionServiceId")
val test = Bundle()
test.putParcelable(TelecomManager.EXTRA_PHONE_ACCOUNT_HANDLE, phoneAccountHandle)
test.putInt(TelecomManager.EXTRA_START_CALL_WITH_VIDEO_STATE, VideoProfile.STATE_BIDIRECTIONAL)
test.putParcelable(TelecomManager.EXTRA_OUTGOING_CALL_EXTRAS, extras)
try {
manager.placeCall(Uri.parse("tel:$number"), test)
} catch (e:SecurityException){
e.printStackTrace()
}
}
@TargetApi(Build.VERSION_CODES.M)
fun startIncomingCall(){
if (this.context.checkSelfPermission(Manifest.permission.MANAGE_OWN_CALLS) == PackageManager.PERMISSION_GRANTED) {
val extras = Bundle()
val uri = Uri.fromParts(PhoneAccount.SCHEME_TEL, number, null)
extras.putParcelable(TelecomManager.EXTRA_INCOMING_CALL_ADDRESS, uri)
extras.putParcelable(TelecomManager.EXTRA_PHONE_ACCOUNT_HANDLE, phoneAccountHandle)
extras.putBoolean(TelecomManager.EXTRA_START_CALL_WITH_SPEAKERPHONE, true)
val isCallPermitted = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
telecomManager.isIncomingCallPermitted(phoneAccountHandle)
} else {
true
}
Log.i("CallManager", "is incoming call permited = $isCallPermitted")
telecomManager.addNewIncomingCall(phoneAccountHandle, extras)
}
}
}
And my custom ConnectionService implementation:
class CallConnectionService : ConnectionService() {
override fun onCreateOutgoingConnection(connectionManagerPhoneAccount: PhoneAccountHandle?, request: ConnectionRequest?): Connection {
Log.i("CallConnectionService", "onCreateOutgoingConnection")
val conn = CallConnection(applicationContext)
conn.setAddress(request!!.address, PRESENTATION_ALLOWED)
conn.setInitializing()
conn.videoProvider = MyVideoProvider()
conn.setActive()
return conn
}
override fun onCreateOutgoingConnectionFailed(connectionManagerPhoneAccount: PhoneAccountHandle?, request: ConnectionRequest?) {
super.onCreateOutgoingConnectionFailed(connectionManagerPhoneAccount, request)
Log.i("CallConnectionService", "create outgoing call failed")
}
override fun onCreateIncomingConnection(connectionManagerPhoneAccount: PhoneAccountHandle?, request: ConnectionRequest?): Connection {
Log.i("CallConnectionService", "onCreateIncomingConnection")
val conn = CallConnection(applicationContext)
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N_MR1) {
conn.connectionProperties = Connection.PROPERTY_SELF_MANAGED
}
conn.setCallerDisplayName("test call", TelecomManager.PRESENTATION_ALLOWED)
conn.setAddress(request!!.address, PRESENTATION_ALLOWED)
conn.setInitializing()
conn.videoProvider = MyVideoProvider()
conn.setActive()
return conn
}
override fun onCreateIncomingConnectionFailed(connectionManagerPhoneAccount: PhoneAccountHandle?, request: ConnectionRequest?) {
super.onCreateIncomingConnectionFailed(connectionManagerPhoneAccount, request)
Log.i("CallConnectionService", "create outgoing call failed ")
}
}
And my Connection implementation is like that:
class CallConnection(ctx:Context) : Connection() {
var ctx:Context = ctx
val TAG = "CallConnection"
override fun onShowIncomingCallUi() {
// super.onShowIncomingCallUi()
Log.i(TAG, "onShowIncomingCallUi")
val intent = Intent(Intent.ACTION_MAIN, null)
intent.flags = Intent.FLAG_ACTIVITY_NO_USER_ACTION or Intent.FLAG_ACTIVITY_NEW_TASK
intent.setClass(ctx, IncomingCallActivity::class.java!!)
val pendingIntent = PendingIntent.getActivity(ctx, 1, intent, 0)
val builder = Notification.Builder(ctx)
builder.setOngoing(true)
builder.setPriority(Notification.PRIORITY_HIGH)
// Set notification content intent to take user to fullscreen UI if user taps on the
// notification body.
builder.setContentIntent(pendingIntent)
// Set full screen intent to trigger display of the fullscreen UI when the notification
// manager deems it appropriate.
builder.setFullScreenIntent(pendingIntent, true)
// Setup notification content.
builder.setSmallIcon(R.mipmap.ic_launcher)
builder.setContentTitle("Your notification title")
builder.setContentText("Your notification content.")
// Use builder.addAction(..) to add buttons to answer or reject the call.
val notificationManager = ctx.getSystemService(
NotificationManager::class.java)
notificationManager.notify("Call Notification", 37, builder.build())
}
override fun onCallAudioStateChanged(state: CallAudioState?) {
Log.i(TAG, "onCallAudioStateChanged")
}
override fun onAnswer() {
Log.i(TAG, "onAnswer")
}
override fun onDisconnect() {
Log.i(TAG, "onDisconnect")
}
override fun onHold() {
Log.i(TAG, "onHold")
}
override fun onUnhold() {
Log.i(TAG, "onUnhold")
}
override fun onReject() {
Log.i(TAG, "onReject")
}
}
According to the document to show user incoming calcustomon UI - I should do some actions in onShowIncomingCallUi() method. But it just does not called by the system.
How can I fix it?
