                startActivity(insertData);
            }

if you want more information please tell me. Thank you

Answer 1

I think there is a Syntax error in your create table sentence, erase the " _ " and put a space after TABLE, and change AUTOINCREMAENT to AUTOINCREMENT like this:

public static String TABLE_CERATE_SQL = "CREATE TABLE "+TABLE_NAME+" ("+"" +
                                            ""+TABLE_KEY_ID+" INTEGER PRIMARY KEY AUTOINCREMENT,"+
                                            ""+TABLE_KEY_FNAME+" text(20), "+
                                            ""+TABLE_KEY_LNAME+" text(30), "+
                                            ""+TABLE_KEY_NICKNAME+" text(20)"+
                                        ")";

Answer 2

You have a syntax error for creating table. it should be like this

public static String TABLE_CERATE_SQL = "CREATE TABLE IF NOT EXISTS "+TABLE_NAME+"("+"" +
                                            ""+TABLE_KEY_ID+" INTEGER PRIMARY KEY AUTOINCREMAENT,"+
                                            ""+TABLE_KEY_FNAME+" text(20), "+
                                            ""+TABLE_KEY_LNAME+" text(30), "+
                                            ""+TABLE_KEY_NICKNAME+" text(20)"+
                                        ")";
