android.database.sqlite.SQLiteConstraintException

android.database.sqlite.SQLiteConstraintException: error code 19: constraint failed

error in my application and not sure why.

It happens when i add a new Inbox item into my database.

here is the Create statement of my inbox table:

CREATE TABLE inbox (uid text, title text, sender text, timeRecieved text, PRIMARY KEY(uid));

implemented using these static final Strings;

public static final String LABEL_INBOX_UID = "uid";
    public static final String LABEL_INBOX_TITLE = "title";
    public static final String LABEL_INBOX_SENDER = "sender";
    public static final String LABEL_INBOX_TIME_RECIEVED = "timeRecieved";

    public static final int COLUMN_INBOX_UID = 0;
    public static final int COLUMN_INBOX_TITLE  = 1;
    public static final int COLUMN_INBOX_SENDER= 2;
    public static final int COLUMN_INBOX_TIME_RECIEVED = 3;

    public static final String TABLE_NAME_INBOX = "inbox";
    public static final String TABLE_CREATE_INBOX = "CREATE TABLE "
        + TABLE_NAME_INBOX + " (" + LABEL_INBOX_UID + " text, "
        + LABEL_INBOX_TITLE + " text, " + LABEL_INBOX_SENDER
        + " text, " + LABEL_INBOX_TIME_RECIEVED + " text, "
     + "PRIMARY KEY(" + LABEL_INBOX_UID + ")" + ");";

And here is the method that gets a inbox item and put it inside a contentValues()

@Override
    protected void insertItem(InboxListItem object, String table) {
        InboxListItem item = object;
        inboxItemValue = new ContentValues();

        inboxItemValue.put(LABEL_INBOX_UID, item.getUid()); 
        Log.d(TAG, "item.getUid() " + item.getUid());
        inboxItemValue.put(LABEL_INBOX_TIME_RECIEVED, item.getTimeRecieved());
        Log.d(TAG, "item.getTimeRecieved() " + item.getTimeRecieved());
        inboxItemValue.put(LABEL_INBOX_TITLE, item.getTitle());
        Log.d(TAG, "item.getTitle() " + item.getTitle());
        inboxItemValue.put(LABEL_INBOX_SENDER, item.getSender());
        Log.d(TAG, "item.getSender() " + item.getSender());


        Log.d(TAG, "TABLE_CREATE_EVENTS =" + TABLE_CREATE_EVENTS);
        Log.d(TAG, "TABLE_CREATE_INBOX =" + TABLE_CREATE_INBOX);
        Log.d(TAG, "TABLE_CREATE_CONTACTS =" + TABLE_CREATE_CONTACTS);
        database().insert(TABLE_NAME_INBOX, null, inboxItemValue);
        Log.d(TAG, "database().insert(TABLE_NAME_INBOX, null, inboxItemValue);");


    }

O and here is the full exception message:

Thanks in advance:

Edit: Somemore info. I had previously created a events and contactsList table succesfully and that seems to work fine. here is the code below:

Contacts:

// Variables used to create the events table
    public static final String TABLE_NAME_CONTACTS = "contactsList";

    public static final String LABEL_CONTACTS_UID = "uid";
    public static final String LABEL_CONTACTS_FULLNAME = "fullname";

    public static final String TABLE_CREATE_CONTACTS = "CREATE TABLE "
            + TABLE_NAME_CONTACTS + " (" + LABEL_CONTACTS_UID + " text, "
            + LABEL开发者_如何学编程_CONTACTS_FULLNAME + " text, " + "PRIMARY KEY("
            + LABEL_CONTACTS_UID + ")" + ");";


    public static final int COLUMN_CONTACTS_UID = 0;
public static final int COLUMN_CONTACTS_FULLNAME = 1;

CREATE TABLE contactsList (uid text, fullname text, PRIMARY KEY(uid));

calendar events:

public static final String LABEL_EVENTS_UID = "uid";
    public static final String LABEL_EVENTS_TITLE = "title";
    public static final String LABEL_EVENTS_LOCATION = "location";
    public static final String LABEL_EVENTS_DATE = "date";
    public static final String LABEL_EVENTS_TIME = "time";
    public static final String LABEL_EVENTS_TIMEZONE = "timezone";

    public static final int COLUMN_EVENTS_UID = 0;
    public static final int COLUMN_EVENTS_TITLE = 1;
    public static final int COLUMN_EVENTS_LOCATION = 2;
    public static final int COLUMN_EVENTS_DATE = 3;
    public static final int COLUMN_EVENTS_TIME = 4;
    public static final int COLUMN_EVENTS_TIMEZONE = 5;

    // Variables used to create the events table
    public static final String TABLE_NAME_EVENTS = "events";
    public static final String TABLE_CREATE_EVENTS = "CREATE TABLE "
            + TABLE_NAME_EVENTS + " (" + LABEL_EVENTS_UID + " text, "
            + LABEL_EVENTS_TITLE + " varchar(30), " + LABEL_EVENTS_LOCATION
            + " varchar(30), " + LABEL_EVENTS_DATE + " varchar(30), "
            + LABEL_EVENTS_TIME + " varchar(30), " + LABEL_EVENTS_TIMEZONE
            + " varchar(30), " + "PRIMARY KEY(" + LABEL_EVENTS_UID + ")" + ");";

CREATE TABLE events (uid text, title varchar(30), location varchar(30), date varchar(30), time varchar(30), timezone varchar(30), PRIMARY KEY(uid));

The only constraint on your table is the primary key, so you're probably trying to insert an item with a non-unique 'UID'.

your primary key is not autoincrement, so you should be responsible to generate unique one each time you insert a record in the table. You can change this behaviour by this:

CREATE TABLE inbox (uid integer PRIMARY KEY AUTOINCREMENT, title text, sender text, timeRecieved text);

@jonney As you said you have added a new table content. or if you update your db version the same error will occur, But no need to worry, You done it Buddy the valid reason is primary key is not autoincrement But solution is Easy Just Uninstall the app and Install it again, One of my Sr. Fraind told me this and it works. Hope Your Problem will be Solved. Best Luck.

Try this:

return db.insertWithOnConflict(YOURTABLENAME, null, initialValues, SQLiteDatabase.CONFLICT_IGNORE);
