Question

I am coding a simple DB application, but when I load the application it says: “The app has stopped unexpectedly”

Here is my code for the Database:

public class EventsData extends SQLiteOpenHelper {

    private static final String DATABASE_NAME = "events.db";
    private static final int DATABASE_VERSION = 1;

    public EventsData(Context ctx) {
        super(ctx, DATABASE_NAME, null, DATABASE_VERSION);
    }

    @Override
    public void onCreate(SQLiteDatabase db){
        db.execSQL("CREATE TABLE " + TABLE_NAME + "(" + _ID + " INTEGER PRIMARY KEY AUTOINCREMENT, "
                 + TIME + " INTEGER, " + TITLE + " TEXT NOT NULL);");
    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        db.execSQL("DROP TABLE IF EXISTS " + TABLE_NAME);
        onCreate(db);
    }

my constants:

import android.provider.BaseColumns;;

public interface Constants extends BaseColumns {
    public static final String TABLE_NAME = "events";
    //columns in the events db
    public static final String TIME = "time";
    public static final String TITLE = "title"; 
}

The error is:

04-14 17:08:12.486: E/Database(277): Failure 1 (AUTOINCREMENT is only allowed on an INTEGER PRIMARY KEY) on 0x217058 when preparing ‘CREATE TABLE events(_idINTEGER PRIMARY KEY AUTOINCREMENT, timeINTEGER, title TEXT NOT NULL);’.

Why is there an error?

Answer 1

You should check for spaces between the field names and their types. The error says:

[…] events(_idINTEGER PRIMARY KEY AUTOINCREMENT, timeINTEGER, title TEXT NOT NULL)

However, your code looks fine. Are you sure that is the actual code?
