I am trying to retrieve my email from my SQLiteDbHelper and view it in a TextView in another activity after I click sign in, using the WelcomeActivity or splash activity since I only want it to be view for 4 seconds, but idk whats the problem when I sign in it crashes me out.

I believe that you have a number of issues.
The line tvEmail.setText(Users.class.getEm); won't compilem I believe that instead want tvEmail.setText(user); or tvEmail.setText(email); (you don't need to have both email and user Strings having the same value).
Assuming that EthicsActivity is a valid working activity, and that there is an appropriate activity entry in the manifest AndroidManifest.xml then the issue is that you would get an error along the lines of :-

This is saying that the Cursor is empty so you cannot get any data from it and it happens at the line String user = cursor.getString(cursor.getColumnIndex(COLUMN_EMAIL)); which is in the getEmail method as indicated by the line in the log :-
at so53240174.so53240174.DataBaseHelper.getEmail(DataBaseHelper.java:96)
The reason why this is happening is that a) there are no rows in the users table and b) that the Cursor moveToFirst method's result isn't checked. Instead an assumption is made that it will always move to the first row in the Cursor.
Instead of the getEmail method being :-
public String getEmail(String COLUMN_EMAIL)
m_db = this.getReadableDatabase();
Cursor cursor = m_db.query(TABLE_USERS, new StringCOLUMN_EMAIL, null, null,
null, null, null);
cursor.moveToFirst(); //<<<<<<<<<< WRONG
String user = cursor.getString(cursor.getColumnIndex(COLUMN_EMAIL));
cursor.close();
return user;
It could be :-
public String getEmail(String COLUMN_EMAIL)
String user = "No Email Found."; //<<<<<<<<<< Default value in case of empty table
m_db = this.getReadableDatabase();
Cursor cursor = m_db.query(TABLE_USERS, new StringCOLUMN_EMAIL, null, null,
null, null, null);
if (cursor.moveToFirst()) //<<<<<<<<<< checks result of the move
user = cursor.getString(cursor.getColumnIndex(COLUMN_EMAIL));
cursor.close();
return user;
Of course applying this fix, unless a row is added to the users table will always result in the TextView displaying No Email Found. If there are multiple rows then it will display the email from one of the rows, not necessarily a specific row.
Adding the line db.insert("fred@fredmail.com","1234567890"); before the value is retrieved using the call to the getEmail results in fred@fredmail.com being displayed in the TextView.

That was helpful sir! but now i have stumbled into a new problem, it is as you said it will retrieve the last username entered, but that's not the case i want my text view in welcome activity capture the email that was entered in the sign in activity, i want to retrieve that for every user i am trying to enter, right now i can only retrieve the last registered user email no matter what other users i am signing in with, do you have an idea how to do that?

I believe that you have a number of issues.
The line tvEmail.setText(Users.class.getEm); won't compilem I believe that instead want tvEmail.setText(user); or tvEmail.setText(email); (you don't need to have both email and user Strings having the same value).
Assuming that EthicsActivity is a valid working activity, and that there is an appropriate activity entry in the manifest AndroidManifest.xml then the issue is that you would get an error along the lines of :-

This is saying that the Cursor is empty so you cannot get any data from it and it happens at the line String user = cursor.getString(cursor.getColumnIndex(COLUMN_EMAIL)); which is in the getEmail method as indicated by the line in the log :-
at so53240174.so53240174.DataBaseHelper.getEmail(DataBaseHelper.java:96)
The reason why this is happening is that a) there are no rows in the users table and b) that the Cursor moveToFirst method's result isn't checked. Instead an assumption is made that it will always move to the first row in the Cursor.
Instead of the getEmail method being :-
public String getEmail(String COLUMN_EMAIL)
m_db = this.getReadableDatabase();
Cursor cursor = m_db.query(TABLE_USERS, new StringCOLUMN_EMAIL, null, null,
null, null, null);
cursor.moveToFirst(); //<<<<<<<<<< WRONG
String user = cursor.getString(cursor.getColumnIndex(COLUMN_EMAIL));
cursor.close();
return user;
It could be :-
public String getEmail(String COLUMN_EMAIL)
String user = "No Email Found."; //<<<<<<<<<< Default value in case of empty table
m_db = this.getReadableDatabase();
Cursor cursor = m_db.query(TABLE_USERS, new StringCOLUMN_EMAIL, null, null,
null, null, null);
if (cursor.moveToFirst()) //<<<<<<<<<< checks result of the move
user = cursor.getString(cursor.getColumnIndex(COLUMN_EMAIL));
cursor.close();
return user;
Of course applying this fix, unless a row is added to the users table will always result in the TextView displaying No Email Found. If there are multiple rows then it will display the email from one of the rows, not necessarily a specific row.
Adding the line db.insert("fred@fredmail.com","1234567890"); before the value is retrieved using the call to the getEmail results in fred@fredmail.com being displayed in the TextView.

That was helpful sir! but now i have stumbled into a new problem, it is as you said it will retrieve the last username entered, but that's not the case i want my text view in welcome activity capture the email that was entered in the sign in activity, i want to retrieve that for every user i am trying to enter, right now i can only retrieve the last registered user email no matter what other users i am signing in with, do you have an idea how to do that?
