Data doesn't get saved in database, which it did before, but after I updated the database version it doesn't

Thanks for helping me fix my problem!
Issue
The issue is that the data never gets saved into the database, which it did before, but then i updated the database version and now it does not.
Is there an error thrown? Yes there is and its right down below.

That's all of my classes. Also, I would like to specify that I don't actually know what database versions are since I started with the android studio 3 days ago.

please try this I implemented some change on the UserInfo class
the Id must be an integer and you add a String
database.java
public class MyBase extends SQLiteOpenHelper {
private static final int DATABASE_VERSION = 5;
private static final String DATABASE_NAME = "UserInfo";
private static final String TABLE_NAME = "Info";
private static final String KEY_ID = "id";
private static final String KEY_USERID = "userid";
private static final String KEY_EMAIL = "email";
private static final String KEY_CODE = "code";
public MyBase(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
#Override
public void onCreate(SQLiteDatabase db) {
String CREATE_TABLE = "CREATE TABLE " + TABLE_NAME + " (" + KEY_ID + " INTEGER PRIMARY KEY AUTOINCREMENT," + KEY_USERID + " INTEGER," + KEY_EMAIL + " TEXT," + KEY_CODE + " TEXT" + ")";
db.execSQL(CREATE_TABLE);
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
db.execSQL("DROP TABLE IF EXISTS " + TABLE_NAME);
onCreate(db);
}
public void addUserInfo(UserInfo info) {
SQLiteDatabase db = this.getWritableDatabase();
ContentValues contentValues = new ContentValues();
// contentValues.put(KEY_ID, info.UserId); i removed this
contentValues.put(KEY_EMAIL, info.Email);
contentValues.put(KEY_USERID, info.UserId);
contentValues.put(KEY_CODE, info.CODE);
db.insert(TABLE_NAME, null, contentValues);
db.close();
}
public List<UserInfo> getUserInfo() {
List<UserInfo> results = new ArrayList<>();
String GET_ALL = "SELECT * FROM " + TABLE_NAME;
SQLiteDatabase db = this.getWritableDatabase();
Cursor cursor = db.rawQuery(GET_ALL, null);
if (cursor.moveToFirst()) {
do {
UserInfo userInfo = new UserInfo(cursor.getInt(0), cursor.getInt(1), cursor.getString(2), cursor.getInt(3));
results.add(userInfo);
} while (cursor.moveToNext());
}
db.close();
return results;
}
public void deleteUserInfo(UserInfo info) {
SQLiteDatabase db = this.getWritableDatabase();
db.delete(TABLE_NAME, KEY_ID + " = ? ", new String[]{String.valueOf(info.ID)});
db.close();
}
}
and UserInfo :
public class UserInfo {
public int ID;
public int UserId;
public String Email;
public int CODE;
public UserInfo(int uid, String mail, int el_code) {
UserId = uid;
Email = mail;
CODE = el_code;
}
public UserInfo(int userId, int uid, String mail, int el_code) {
UserId = uid;
Email = mail;
ID = userId;
CODE = el_code;
}
}
i hope that's help you

Can you please help me find the solution and tell me what is wrong :(

I am not sure where your error comes from but, I am assuming its on launch or when you insert the data.
I create my SQL table like below.
However, I did encounter a really annoying issue of if I change my table my app would crash as it would not find it. The fix was I needed to uninstall the app on my phone before uploading the application from android studio to my phone. Hope it helps
public class DatabaseHelper extends SQLiteOpenHelper {
public static final String DATABASE_NAME ="TESTING.db";
// Database Version
private static final int DATABASE_VERSION = 1;
public static final String TABLE_1 = "T1";
public static final String TABLE_2 = "T2";
public static final String TABLE_3 = "T3";

public static final String COL2 = "D1";
public static final String COL3 = "D2";
public static final String COL4 = "D3";
public static final String COL5 = "D4";
public static final String COL6 = "D5";
public static final String COL7 = "D6";
public static final String COL8 = "time";
public DatabaseHelper(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
#Override
public void onCreate(SQLiteDatabase db) {
// creating required tables
String Created_TABLE_1= "CREATE TABLE " + TABLE_1 + " (ID INTEGER PRIMARY KEY, " +
"D1 TEXT, D2 TEXT, D3, TEXT, D4 TEXT, D5 TEXT, D6 TEXT, TIME TEXT)";
String Created_TABLE_2= "CREATE TABLE " + TABLE_2 + " (ID INTEGER PRIMARY KEY, " +
"D1 TEXT, D2 TEXT, D3, TEXT, D4 TEXT, D5 TEXT, D6 TEXT, TIME TEXT)";
String Created_TABLE_3= "CREATE TABLE " + TABLE_3 + " (ID INTEGER PRIMARY KEY, " +
"D1 TEXT, D2 TEXT, D3, TEXT, D4 TEXT, D5 TEXT, D6 TEXT, TIME TEXT)";
db.execSQL(Created_TABLE_1);
db.execSQL(Created_TABLE_2);
db.execSQL(Created_TABLE_3);
}
Ps Stay safe all

Thank you Eugene Troyanskii, forpas and Thomas Morris. I've solved the problem. Supposed to be assign with correct name for column according to create table statement at inserting data code, but I write it different.
Again thanks guys!

Data type mismatch when inserting data into android app database

I'm not entirely sure what could be happening, I know that there is a mismatch when I try to insert, but when I double check my code I can't see why it would spit that error out. I am simply trying to insert a username and password (both are Strings).
CONTEXT:
In my RegisterLoginActivity.java I made it when the user taps the TextView "Create account" it will grab the username and password and turn them into strings.
Then in my DatabaseOperations.java I use the function putInformation() to insert the data.
My TableData.java simply contains my table information.

The exception message says this:
no such table: users (code 1) while compiling "SELECT _id, u_name, u_pass FROM users"
It is looking for a table called "users" in the database, but it can't find one!
Either you haven't set up your database correctly (e.g. you haven't created the tables) or the schema (e.g. table names) for your database doesn't match what the application requires.
In fact, look at your onCreate method. All it is doing is creating and throwing away a string containing some SQL. You need to execute it ....

You really need to execute your table creation:
String CREATE_USERS_TABLE = "CREATE TABLE " + DB_TABLE + "(" + KEY_ROWID +
" INTEGER PRIMARY KEY," + KEY_NAME + " TEXT," + KEY_PASS + " TEXT" + ")";
db.execSQL(CREATE_USERS_TABLE);
You also need to call your onCreate() method inside your onUpgrade() method
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion)
{
db.execSQL("DROP TABLE IF EXIST " + DB_TABLE);
onCreate(db);
}

How to get the list item name from a listview to a textview in another activity?

Im creating an app where users can enter the movies they own, to show in a listview, and for random picking a movie from that list.
Now what my problem is, that when clicking on an item in the listview a new activity opens op where the item clicked is the title in a textview. So far i can get the movie from the list who is number 1 to show, but that shows it's title no matter which list item I click, how can i get the specific name depending on what item is clicked?? Thanks in advance.

Button delete = (Button) findViewById(R.id.delete);
Movietitle.setText( databaseHelper.getMovieTitle());
}
}

Well, there is lot of code you are asking for. But I can tell you the steps
Create a Model Class for your movie,, where you can hold the db records
Create list of Model Class and then when you click the item, you get the position of record in list.
Your movie Model class must have getter and setter functions to retrieve record details.
