I'm creating an app for detecting deleted WhatsApp Messages.
I used a notification listener to detect messages from WhatsApp.
But it detects all notification messages from WhatsApp, while I want to detect only the deleted message.
Can anyone help me?

Deleting a message inside WhatsApp does not post a notification. Thus the answer to your question is, it's impossible to do with a NotificationListener

I have a problem in my Android app. I have a service for geolocalization and I need to save the position on my DB.
When the app is running in the foreground I can to save the position, but when the app is running in the background the information isn't saved.
I used Firebase with Android.
Thanks.
With Android 10 for accessing location in background you need special permisson, or you can do it with a foreground service.

In the Android application, I am developing a one functionality that sends sms messages to given numbers automatically when the application is running. That function is working properly but after the messages is sent the cost for that messages prompts on a alert box.
Normally when I send a message that alert box prompts. But in my application I want to disable it because it disturbs to my application. How can I achieve that.
If you have any Idea then Please Guide me.

These pop-ups are flash messages that are generated by SIMCARD network provider. There is nothing you can do about it from your app end to put an end to them. But, you can stop it by disabling SIMCARD Services settings.
For disabling flash message you may check the link:

It has a process mentioned. So if you can have your all customers devices with you, sure you can stop it, otherwise NO.
Authors Note : Better stop worrying about it ;)

Is it possible to send an SMS from an Android app and change the sender number, so that the receiver will see the SMS as coming from someone else?
I'm not doing this for pranks or illegal systems, it's something necessary.
Thank you
I don't believe this is possible, and would find it highly questionable if it were.
If you're simply looking to give someone the ability to send a message to a number using your app as a service. Then try using Twilio www.twilio.com or something similar where you can pick a number and send message to others. Although you will be paying for the SMS's that are sent and this may not be what you want.
This is possible, but you need a sms server/gateway or an online provider which does it for you. You could even enter text as your number (companies like facebook and google do this).

I am new at android and I am trying to make an android app which takes from you the time and sends a message to user at that time. Can someone tell me the steps to follow so I can make this app.
This is actually pretty simple. One way to do this (may not be the simplist but would give you good experience with a bunch of the android framework:
Register a BroadcastReceiver
Gather the information (message, destination, time) from the user using UI elements.
Send an intent to the BroadcastReciever with the time specified.
Send the sms from the BroadcastReceiver, using SmsManager.
This would also give you a lot of opportunity to add to this app, you can learn to use Content Providers to keep track of the current 'Pending Messages' and give the user an option to view and edit them.
