несколько таблиц в SQL android studio

Question

Я создал несколько таблиц в sql, как показано другим разработчиком, и после того, как я попытался зарегистрировать пользователя, приложение, к сожалению, остановилось. Вот некоторый код в databasehelper

, это таблицы открытого классасоздать метод вставки для вставки данных в публичную логическую вставку базы данных (String FirstName, String SecondName, String Email, String Password) {

    SQLiteDatabase sqLiteDatabase = this.getWritableDatabase();

    //create content values
    ContentValues values1 = new ContentValues();
    values1.put("FirstName", FirstName);
    values1.put("SecondName", SecondName);
    values1.put("Email", Email);
    values1.put("Password", Password);

    //insert into database table
    sqLiteDatabase.insert(TABLE_USERS1, null, values1);
    return true;
}
public boolean insert2 (String FullName, String StudentNumber, String Course, String Level) {
    SQLiteDatabase sqLiteDatabase = this.getWritableDatabase();
    //create content values
    ContentValues values2 = new ContentValues();
    values2.put("FullName", FullName);
    values2.put("StudentNumber", StudentNumber);
    values2.put("Course", Course);
    values2.put("Level", Level);

    //insert into database table
    sqLiteDatabase.insert(TABLE_USERS2, null, values2);
    return true;
}
public boolean insert3 (String Cand_Name, String Counts){
    SQLiteDatabase sqLiteDatabase = this.getWritableDatabase();

    //create content values for categories
    ContentValues values3 = new ContentValues();
    values3.put("Cand_Name", Cand_Name);
    values3.put("Counts", Counts);

    //insert into categories tables
    sqLiteDatabase.insert(TABLE_CATEGORY1, null, values3);

    //create content values for categories
    ContentValues values4 = new ContentValues();
    values4.put("Cand_Name", Cand_Name);
    values4.put("Counts", Counts);

    //insert into categories tables
    sqLiteDatabase.insert(TABLE_CATEGORY2, null, values4);

    //create content values for categories
    ContentValues values5 = new ContentValues();
    values5.put("Cand_Name", Cand_Name);
    values5.put("Counts", Counts);

    //insert into categories tables
    sqLiteDatabase.insert(TABLE_CATEGORY3, null, values5);

    //create content values for categories
    ContentValues values6 = new ContentValues();
    values6.put("Cand_Name", Cand_Name);
    values6.put("Counts", Counts);

    //insert into categories tables
    sqLiteDatabase.insert(TABLE_CATEGORY4, null, values6);

    //create content values for categories
    ContentValues values7 = new ContentValues();
    values7.put("Cand_Name", Cand_Name);
    values7.put("Counts", Counts);

    //insert into categories tables
    sqLiteDatabase.insert(TABLE_CATEGORY5, null, values7);

    //create content values for categories
    ContentValues values8 = new ContentValues();
    values8.put("Cand_Name", Cand_Name);
    values8.put("Counts", Counts);

    //insert into categories tables
    sqLiteDatabase.insert(TABLE_CATEGORY6, null, values8);

    //create content values for categories
    ContentValues values9 = new ContentValues();
    values9.put("Cand_Name", Cand_Name);
    values9.put("Counts", Counts);

    //insert into categories tables
    sqLiteDatabase.insert(TABLE_CATEGORY7, null, values9);

    //create content values for categories
    ContentValues values10 = new ContentValues();
    values10.put("Cand_Name", Cand_Name);
    values10.put("Counts", Counts);

    //insert into categories tables
    sqLiteDatabase.insert(TABLE_CATEGORY8, null, values10);

    //create content values for categories
    ContentValues values11 = new ContentValues();
    values11.put("Cand_Name", Cand_Name);
    values11.put("Counts", Counts);

    //insert into categories tables
    sqLiteDatabase.insert(TABLE_CATEGORY9, null, values11);

    //create content values for categories
    ContentValues values12 = new ContentValues();
    values12.put("Cand_Name", Cand_Name);
    values12.put("Counts", Counts);

    //insert into categories tables
    sqLiteDatabase.insert(TABLE_CATEGORY10, null, values12);
    return true;
}
//checking if the email existing
public Boolean chkemail (String Email){
    SQLiteDatabase db = this.getReadableDatabase();

    Cursor cursor = db.rawQuery("select * from Admin where Email=?", new String[]{Email});
    if (cursor.getCount()>0) return false;
    else return true;

}
//checking if the Student number existing
public Boolean chkStudentNo (String StudentNumber){
    SQLiteDatabase db = this.getReadableDatabase();

    Cursor cursor = db.rawQuery("select * from Student where StudentNumber=?", new String[]{StudentNumber});
    if (cursor.getCount()>0) return false;
