Failed to convert value of type java.lang.Long to Timestamp(Java,android studio)

Hi I'm following this video tutorial https://www.youtube.com/watch?v=wQN2eCO-M_Q&t=7717s (the part I suppose create this issue can be found at time 2:01:17)and I managed to make this code work without implementing the notifications, but it only works on the simulator.
When I try to debug it with my phone it gives me the following error
E/AndroidRuntime: FATAL EXCEPTION: main
Process: com.example.chat, PID: 7894
java.lang.RuntimeException: Could not deserialize object. Failed to convert value of type java.lang.Long to Timestamp (found in field 'timestamp')
On others real devices it works properly but on my real me 8 pro it does not
here is some code from my android studio:
ChatModel.java
package com.example.chat.model;
import com.google.firebase.Timestamp;
import java.sql.Time;
import java.util.Date;
public class ChatModel {
String message;
String user_name;
String messageID;
String user_image_url;
String chat_image;
Timestamp timestamp;
public ChatModel() {
}
public ChatModel(String message, String user_name, String messageID, String user_image_url, String chat_image, Timestamp timestamp) {
this.message = message;
this.user_name = user_name;
this.messageID = messageID;
this.user_image_url = user_image_url;
this.chat_image = chat_image;
this.timestamp = timestamp;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public String getUser_name() {
return user_name;
}
public void setUser_name(String user_name) {
this.user_name = user_name;
}
public String getMessageID() {
return messageID;
}
public void setMessageID(String messageID) {
this.messageID = messageID;
}
public String getUser_image_url() {
return user_image_url;
}
public void setUser_image_url(String user_image_url) {
this.user_image_url = user_image_url;
}
public String getChat_image() {
return chat_image;
}
public void setChat_image(String chat_image) {
this.chat_image = chat_image;
}
public Timestamp getTimestamp() {
return timestamp;
}
public void setTimestamp(Timestamp timestamp) {
this.timestamp = timestamp;
}
}
i have tried to change Timestamp with: long, Long, Date and Number.
But i wouldn't work anyways

How to delete all RecyclerView items from SQLite Database?

I am a beginner at coding in Java. I am creating a notes app with lots of other features. And one of the features are, storing the user's bank card details in a RecyclerView. I did this by making an SQLite CRUD. All of the Create, Read, Update and Delete works. And I protected this page with a Pattern lock.
And when we are in the Input Pattern page, we can see a clickable text called Click HERE if you forgot your pattern, That works. And when you click on that clickable text, the app shows an Alert Dialog, titled are you sure? and the message is If you change your pattern, all your data will be deleted then there are two buttons Yes and No. No does nothing, it just cancel the forgot pattern thing. But the problem is with the Yes button.
When we click it, It should delete all bank cards or delete all data. Please suggest a way to delete all data from the SQLite Database. I tried lots of ways to do this.

I'm trying to add GPS functionality to my android app, gps coordinates come out to 0.0, 0.0 every time

I'd like to check GPS both when the app is started and when the refresh button is hit, and use those data points, in the form of mLatitude and mLongitude to call the weather api. Eventually I'm going to geocode the city but right now for debugging purposes I'm outputting the GPS coordinates to the locationLabel textview.

Here are two things you can try:
1. Please ensure you have included the ACCESS_FINE_LOCATION and ACCESS_COARSE_LOCATION permissions in your manifest. If your app targets Android API 23 and above, you will need to include runtime permission handling.
2. Instead of having a LocationListener object as a class member, you should have your Service implement it as an interface and implement its onLocationChanged() method.
Apart from this, you really should consider using the location APIs' in Google Play Services, rather than those in AOSP (i.e. android.location).
