Question

When I try to create the a table the very first time, I always get this error message:

sqlite returned: error code = 1, msg = AUTOINCREMENT is only allowed
on an INTEGER PRIMARY KEY

My code looks like this:

// debuggin identifier
private static final String TAG = DatabaseOpenHandler.class.getSimpleName();

// name and verison of the database
private static final String DATABASE_NAME = "OpenConfApp";
private static final int DATABASE_VERSION = 1;

// name and attributes of the table notes
public static final String TABLE_NAME_NOTES = "notes";
public static final String _NOTE_ID = "_noteId";
public static final String NOTE_CONFERENCE = "conferenceId";
public static final String NOTE_DATE = "dateInMillis";
public static final String NOTE_TEXT = "noteText";

// create table notes
public static final String TABLE_NOTES_CREATE = "CREATE TABLE "
        + TABLE_NAME_NOTES + " (" + _NOTE_ID
        + "INTEGER PRIMARY KEY AUTOINCREMENT, " + NOTE_CONFERENCE
        + " INTEGER, " + NOTE_DATE + " INTEGER, " + NOTE_TEXT
        + " INTEGER);";

// drop table notes
public static final String TABLE_NOTES_DROP = "DROP TABLE IF EXIST "
        + TABLE_NAME_NOTES;

public DatabaseOpenHandler(Context context) {
    super(context, DATABASE_NAME, null, DATABASE_VERSION);
}

@Override
public void onCreate(SQLiteDatabase db) {
    Log.d(TAG, "onCreate called");
    db.execSQL(TABLE_NOTES_CREATE);
}

Sorry, I’m new to Android programming.

Your code is correct Just you missed a space before your first integer statement.Write this:

public static final String TABLE_NOTES_CREATE = "CREATE TABLE "
    + TABLE_NAME_NOTES + " (" + _NOTE_ID
    + " INTEGER PRIMARY KEY AUTOINCREMENT, " + NOTE_CONFERENCE
    + " INTEGER, " + NOTE_DATE + " INTEGER, " + NOTE_TEXT
    + " INTEGER);";
