Forgot password in android using SQLite

I implemented forgot password but i am getting an error. My db contains data.
Here is the logcat:

SQLite Save Error NOT NULL Constraint

I have a local database in my app for storing user profiles from input fields. I have created the database using SQLiteOpenHelper class but after running my app, this error appears. I have been through the DatabaseHelper class but can't find what's wrong with it. I hope someone points out my mistake. Thanks.
my db class file here:

The error occurs in my MainActivity when I call saveInputField() method of DBHelper, shown below:

#Override

try {

JSONObject userObject = verifyObject.getJSONObject("user");
userId = userObject.getString("_id");
Log.d(TAG, "Retrieved user id is:\t" + userId);
TingTingUser user = new TingTingUser();
user.setDisplayName(fullName);
user.setMobileNumber(num);
user.setGender(genderVal);
user.setDob(dob);
user.setOccupation("default");
user.setOrganization("default");
user.setUserId(userId);
if (!TextUtils.isEmpty(fullName) && !TextUtils.isEmpty(genderVal) && !TextUtils.isEmpty(dob) && !TextUtils.isEmpty(userId)){
if (dbHelper.saveInputField(user) == true){ // error occurs here
Toast.makeText(getContext(), "Saved User", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(getContext(), "Save Failed", Toast.LENGTH_SHORT).show(); // Toast shows cos save failed, dont know why
}
}
Sorry guys, my mainactivity is too long, only showed what is necessary.

Your create statement is invalid because you have put into comments the last line so it terminates in + COL_ORGANIZATION + " TEXT, "; which is not correct. The ending should be:

Android SQLite first use: Error java.lang.IllegalArgumentException: column '_id' does not exist

I know, there are a lot of answers already. But I'm a newbie on using SQLite yet and I tried what those answers say but nothing works.
It says my column id doesn't exist but it does exist:
public class SQLite extends SQLiteOpenHelper {
// All Static variables
// Database Version
private static final int DATABASE_VERSION = 1;
// Database Name
private static final String DATABASE_NAME = "OMDBAPI";
// Films table name
static final String TABLE_FILMS = "films";
// Contacts Table Columns names
static final String KEY_TITLE = "Title";
static final String KEY_YEAR = "Year";
static final String KEY_RELEASED = "Released";
static final String KEY_RUNTIME = "Runtime";
static final String KEY_GENRE = "Genre";
static final String KEY_DIRECTOR = "Director";
static final String KEY_WRITER = "Writer";
static final String KEY_ACTORS = "Actors";
static final String KEY_PLOT = "Plot";
static final String ID = "_id";
public SQLite(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
#Override
public void onCreate(SQLiteDatabase db) {
String CREATE_FILMS_TABLE = "CREATE TABLE " + TABLE_FILMS +"(" +
ID + "integer primary key autoincrement," +
KEY_TITLE + " TEXT, " +
KEY_YEAR + " TEXT, " +
KEY_RELEASED + " TEXT, " +
KEY_RUNTIME + " TEXT, " +
KEY_GENRE + " TEXT, " +
KEY_DIRECTOR + " TEXT, " +
KEY_WRITER + " TEXT, " +
KEY_ACTORS + " TEXT, " +
KEY_PLOT + " TEXT" +
");";
db.execSQL(CREATE_FILMS_TABLE);
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
// Drop older table if existed
db.execSQL("DROP TABLE IF EXISTS " + TABLE_FILMS);
// Create tables again
onCreate(db);
}
}
And I try to populate this on a listview:
public class Query extends Activity {
private ListView list;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.list_view);
DBController crud = new DBController(getBaseContext());
Cursor cursor = crud.loadData();
String[] titles = new String[] {SQLite.ID, SQLite.KEY_TITLE};
int[] idViews = new int[] {R.id.idnumber, R.id.grid_title};
SimpleCursorAdapter adapter = new SimpleCursorAdapter(getBaseContext(),
R.layout.adapter_layout,cursor,titles,idViews, 0);
list = (ListView)findViewById(R.id.listView);
list.setAdapter(adapter);
}
}
This is my DB CONTROLLER (Newbie mistake? Should I put the ID here too?):
public class DBController {
private SQLiteDatabase db;
private SQLite bank;
String success = "Film saved.";
String failed = "There was a problem saving the movie.";
public DBController(Context context){
bank = new SQLite(context);
}
public String insertData(String title, String release, String year, String writers, String actors, String director, String genre, String plot, String runtime){
ContentValues values;
long result;
db = bank.getWritableDatabase();
values = new ContentValues();
// Insert values
values.put(SQLite.KEY_TITLE, title);
values.put(SQLite.KEY_YEAR, release);
values.put(SQLite.KEY_RELEASED, release);
values.put(SQLite.KEY_YEAR, year);
values.put(SQLite.KEY_GENRE, genre);
values.put(SQLite.KEY_DIRECTOR, director);
values.put(SQLite.KEY_WRITER, writers);
values.put(SQLite.KEY_ACTORS, actors);
values.put(SQLite.KEY_PLOT, plot);
values.put(SQLite.KEY_RUNTIME, runtime);
result = db.insert(SQLite.TABLE_FILMS, null, values);
db.close();
if (result ==-1)
return failed;
else
return success;
}
public Cursor loadData(){
Cursor cursor;
String[] fields = {bank.KEY_TITLE,bank.KEY_RELEASED};
db = bank.getReadableDatabase();
cursor = db.query(bank.TABLE_FILMS, fields, null, null, null, null, null, null);
if(cursor!=null){
cursor.moveToFirst();
}
db.close();
return cursor;
}
}
Can someone help me find out why it says I don't have an ID column?
(Why are ppl downvote the post? I thought Stack Overflow was to help idiots like me =P)

You don't have _id column, you have _idinteger because you forgot to put a space in the CREATE query. Change the line
ID + "integer primary key autoincrement," +
to
ID + " integer primary key autoincrement," +

You can use baseColums interface that provides a primary key field (called _ID)
An example from google

SQLIte database not able to delete entries

I have a SQLdatabase and I want to delete entries that are displayed in a list view using a button that is next to each entry on the list view. But currently it is not letting me delete.
This problem is located in the selectionargs variable as shown below. If I put a number e.g. 1, into the selectionargs manually it will work, but I have been trying to do it through the a variable that represents each entry. This does not result in an error but just goes straight to the toast message cannot delete. ac.ID refers to the adapter class and the ID of the list item entries.

The code for the delete button is in my bookmark class with the DBManager holding the actual delete code. If anyone can help with this it would be greatly appreciated.

Remove the ac field of your myAdapter class, and use it as a method variable inside the getView method.
Then use the ListView.setOnItemClickListener method to add an on click listener with positional awareness. (do this only once after you set the adapter) This way you can do listItem.get(position) to get the item in that position.

SQLiteException: no such column error [duplicate]

This question already has answers here:
When does SQLiteOpenHelper onCreate() / onUpgrade() run?

Closed 6 years ago.
I have looked through SO and found many people having this same error, but they seem to be forgetting to add the column into the create statement or missing whitespace, neither of which I believe I did.

Thank you to anyone who can tell me why it is telling me the column "QUANTITY" is not being created, I really don't know.

If you change the schema you should increment DATABASE_VERSION so the database is upgraded.
