Receiving messages from ejabberd XMPP server on Android client

I am trying to create an Android chat client using ejabberd XMPP server (19.02), Smack library (4.2.4) and Android SDK 25 using Android Studio.
I followed the example app found here: https://www.blikoontech.com/tutorials/android-smack-xmpp-introductionbuilding-a-simple-client
All is working well and I can send messages between two different Android devices running that sample app.
In ejabberd, there are options to send messages to the clients directly from the server using a CLI tool called ejabberdctl or ejabberd REST API. When I sent messages that way, the Android client doesn’t receive those messages. I tried with other clients like Conversations and Gajim and they could all receive it. I am pretty sure messages sent using those methods arrived because they were received as offline messages (on ejabberd web admin) when sent to offline clients.
Here is the part of the Android (java) code (roosterconnection.java from that sample app) that is to receive incoming messages. Please suggest me if I am missing anything. Thanks a lot.
ChatManager.getInstanceFor(mConnection).addIncomingListener(new IncomingChatMessageListener() {
#Override
public void newIncomingMessage(EntityBareJid messageFrom, Message message, Chat chat) {
///ADDED
Log.d(TAG,"message.getBody() :"+message.getBody());
Log.d(TAG,"message.getFrom() :"+message.getFrom());
String from = message.getFrom().toString();
String contactJid="";
if ( from.contains("/"))
{
contactJid = from.split("/")[0];
Log.d(TAG,"The real jid is :" +contactJid);
Log.d(TAG,"The message is from :" +from);
}else
{
contactJid=from;
}
//Bundle up the intent and send the broadcast.
Intent intent = new Intent(RoosterConnectionService.NEW_MESSAGE);
intent.setPackage(mApplicationContext.getPackageName());
intent.putExtra(RoosterConnectionService.BUNDLE_FROM_JID,contactJid);
intent.putExtra(RoosterConnectionService.BUNDLE_MESSAGE_BODY,message.getBody());
mApplicationContext.sendBroadcast(intent);
Log.d(TAG,"Received message from :"+contactJid+" broadcast sent.");
///ADDED
}
});

Here is a possible explanation, based in my experiments with a desktop client, Tkabber:
I login to ejabberd using Tkabber client, account user1#localhost, resource tka1, priority -3. The negative priority in this experiment is important.
Then I execute the command to send to full JID, including the correct resource:
ejabberdctl send_stanza aaa#localhost user1#localhost/tka1
"<message>..."
The client receives the stanza correctly.
Now I send to bare JID (without providing resource), and another setting another resource:
ejabberdctl send_stanza aaa#localhost user1#localhost
"<message>..."
ejabberdctl send_stanza aaa#localhost user1#localhost/sdsd
"<message>..."
In those cases, none of them are received by the client, because the resource doesn't match, and because its priority is negative. I can see those messages stored offline in the database.
In your client, maybe you have to add another call to set the presence online, with a positive priority.

Reading SMS using Appium on Android

I am trying to automated a flow where I can read sms and then parse the SMS to read the OTP and enter it in another webapp. Looked through all forums but couldn't find an answer.
I am writing code in java and trying to run a webapp on android device using appium.
Can someone suggest how to do it?

If you want to read sms from device in Appium session there is a good approach described in discuss.appium.io
I think you can create several sessions in one test: 1 - to get sms with native app, 2 - open webApp in mobile browser and do whatever you need

This approach worked for me
Suppose your OTP sms is like "OTP is 12345 for your order", and it shows up in your notification panel,
Reach the OTP Screen
Pull down the notification bar ((AndroidDriver) driver).openNotifications();
Wait for this element otpElement with xpath //android.widget.TextView[contains(#text,'OTP is')] is displayed (ie, While the sms arrives)
Use OTPmessage = otpElement.getText() to get the OTP message text
Extract OTP using this code : String OTP = StringUtils.substringBetween(OTPmessage, "OTP is ", " for ");
Close notification panel using ((AndroidDriver) driver).pressKey(new KeyEvent(AndroidKey.BACK));
I dont think this is a good approach if you are testing the app. It might take lot of time for the OTP to arrive thereby failing your test unnecessarily. Better ask your devs keep the OTP fixed so you don't need to receive it through the sms everytime.

You can add a key to store last OTP in an in-memory storage like Redis or closured Dictionary in your backend language, you will then update this key with the value of the OTP you want to send out via an SMS service provider. The last sent OTP stored in this key should then be exposed via an additional api endpoint in your service, which you would then call as part of your automated script after doing an action that will make the OTP to be sent.
A more reliable and robust modification of this will be to expose an API that retrieves the OTP stored against each phone number, you must have this stored already of course before you could do the verification in-app. This endpoint must only be exposed within a test environment, that's the precaution to pay attention to, or you make the endpoint available only to authorized user roles.

Send automatic message via android app

I'm just wondering is it possible to send a Message from the app without using actionView or actionSend ( meaning no asking for chooser to send via google or hotmail etc.. ) from the Intent ?
what I want to make is like a TextView and a Button
the user will enter a text in the textview and then click the Button to send the message, then the message will be automiatlly sent to the developer ( me )
I hope what I'm thinking of is possible.

I'm not sure what kind of message you are trying to send, but you can use the SMS feature of the phone to send not only a SMS, but an email, too.
SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage("1"+yourPhoneNumber, userPhoneNumber, message, null, null);
You can replace phone numbers with emails and it will work without user interaction (unlike sending an email through an email client which cannot be done automatically). You can try it out by texting your own email. For your specific situation, you could set up a developer email that handles all of these messages that you are trying to send. The only issue with this is that you may not know who you are receiving messages from. For example, if you send a SMS -> email, it might show up as from something#vz.com or something. However, you can mitigate this by including addition info in the message payload itself.

Yes, it is possible. You can use the internet connection to have the message saved to some cloud storage or something. Personally, I prefer using Parse.com because they have an amazing API that saves you a lot of hassle.
Just add the message from the EditText to a ParseObject and call the saveEventually() method. As soon as the internet is back on, the message will be sent to your cloud storage.

How to get sms/mms delivery report while sending through intent?

I am trying to send sms from my android app using intent, i have checked out other links too to get the delivery report, but all of them are using SMS-Manager, but here I'm using intent and i am calling the device default sms app.
the code is like this:
Intent inten = new Intent(Intent.ACTION_SEND);
inten.setType("text/*"); //for text
inten.putExtra("sms_body", body);
inten.putExtra("sms_body", body);
But if suppose the user doesn't have the sms balance, or the minimum balance required to send the sms, then obviously the sms won't be send, then how to
1> get the notification,
2> notify the user that his sms is not sent, and
3> the reason because of which it is not sent. (may be insufficient balance, or incorrect phone number, or any other possibilities)
basically i need to get the delivery report, is it possible to get that
and if I am sending the sms to multiple person then out of that list who got that sms, and who didn't
Thanks

Efficeint Handling of Multipart SMS or Long SMS in Android

I have a few questions on Android SMSManager.
How do I send long SMS, say more than 160 characters. My application send SMS
as an email when there if no wifi/data connection. The SMS as email
is retrieved by the server and the server sent a msg: "Your email has been
recieved". How do I show this message on the alert dialog box.
How do I retrieve long SMS?
Four of my activity is supposed to send sms, so do i need to have multiple BroadcastReciecver for each activity or can i simple handle with one BroadcastReciever? Can i have a snippet code on such?
Currently i part of code handles as all above. But i know my codes are in-efficeint. Thats one reason i have such question.
Please bear my question.
