I'm trying to start a conference call from my android app but it doesn't work, what I tried is:
Intent intent1 = new Intent(CreateGroupCallActivity.this,SinchClientService.class); intent1.setAction(SinchClientService.ACTION_GROUP_CALL); String id = String.valueOf(uid) + "-" + call_id.getText().toString(); intent1.putExtra(SinchClientService.INTENT_EXTRA_ID,id); startService(intent1); and in my SinchClientService:
if(intent.getAction().equals(ACTION_GROUP_CALL)) { String id = intent.getStringExtra(INTENT_EXTRA_ID); if(id != null) groupCall(id); } public void groupCall(String id) { if (mCallClient != null) { Call call = mCallClient.callConference(id); CurrentCall.currentCall = call; Log.d("call", "entered"); Intent intent = new Intent(this, GroupCallService.class); startService(intent); } } and here is my GroupCallService
public class GroupCallServiceInterface extends Binder { public String getCallState() { return mCall.getState().toString(); } public String getCallerId() { return mCall.getRemoteUserId(); } public String getCallerName() { if(mFriendName == null) return "The call creator isn't a friend with you"; return mFriendName; } public void endCall() { GroupCallService.this.endCall(); } public void answerCall() { GroupCallService.this.answer(); } public void declineCall() { GroupCallService.this.decline(); } } @Override public void onCreate() { super.onCreate(); //connManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); timeZone = TimeZone.getDefault(); if(CurrentCall.currentCall == null) stopSelf(); mCall = CurrentCall.currentCall; mCall.addCallListener(this); mAudioPlayer = new AudioPlayer(this); mFriendName = ChatDatabaseHandler.getInstance(this).getFriendName(mCall.getRemoteUserId()); /*location = intent.getStringExtra("location"); longitude = intent.getStringExtra("longitde"); latitude = intent.getStringExtra("latitude");*/ mExecutorService = Executors.newSingleThreadExecutor(); mExecutorService.submit(new Runnable() { @Override public void run() { showNotification(); } }); if(mCall.getDirection() == CallDirection.INCOMING) { mAudioPlayer.playRingtone(); Intent intent = new Intent(this, GroupIncomingCallScreen.class); /*intent.putExtra("location", location); intent.putExtra("longitude", longitude); intent.putExtra("latitude", latitude);*/ intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(intent); } else { Intent intent = new Intent(this, GroupCallScreenActivity.class); /*intent.putExtra("location", location);

} private void showNotification(){ Intent intent = new Intent(this, GroupCallService.class); intent.setAction(ACTION_RESTORE_ACTIVITY); PendingIntent pendIntent = PendingIntent.getService(this, 0, intent, 0); NotificationCompat.Builder builder = new NotificationCompat.Builder(this); String name = ChatDatabaseHandler.getInstance(this).getFriendName(mCall.getRemoteUserId()); if(name == null) builder.setContentTitle("Call is in progress");
