Second SQLite issue, login to my application

I have encountered my second issue when using SQLite to create a login/register activity for my app. I am following an online tutorial, I think I understand it all and I have followed what he did exactly, it worked for him, but my application crashes. Here is the function within my database:

 public Cursor getInformation(DatabaseOperations dop){
    SQLiteDatabase SQ = dop.getReadableDatabase();
    String[] columns = {TableData.TableInfo.USER_NAME, TableData.TableInfo.USER_PASS, TableData.TableInfo.USER_EMAIL};
    Cursor CR = SQ.query(TableData.TableInfo.TABLE_NAME, columns, null, null, null, null, null);
    return CR;
}

The issue occurs once I have clicked the login here is the code for the button:

 public void SignInOnClick(View view){
    Bundle b = getIntent().getExtras();
    int status = b.getInt("status");
    if(status == 1){
        Toast.makeText(getBaseContext(),"Please wait...",Toast.LENGTH_LONG).show();
        email = Email.getText().toString();
        password = Password.getText().toString();
        DatabaseOperations DOP = new DatabaseOperations(CTX);
        Cursor CR = DOP.getInformation(DOP);
        CR.moveToFirst();
        boolean loginstatus = false;
        String NAME = "";
        do
        {
                if(email.equals(CR.getString(2)) && (password.equals(CR.getString(1))))
                {
                    loginstatus = true;
                    NAME = CR.getString(0);
                }
        }while(CR.moveToNext());
        if(loginstatus)
        {
            Toast.makeText(getBaseContext(),"Login Successful \n Welcome"+NAME, Toast.LENGTH_LONG).show();
            finish();
        }
        else
        {
            Toast.makeText(getBaseContext(), "Login Failed", Toast.LENGTH_LONG).show();
            finish();
        }
    }
}

The error reads as the following according to logcat:

Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'int android.os.Bundle.getInt(java.lang.String)' on a null object reference
