Code

  Personal Static Class DBHelper extends SQLiteOpenHelper {public DBHelper (reference reference) {super (reference, Database_Name, Null, DATABASE_VERSION); } @Override Public Zero OnCreate (SQLiteDatabase Database) {db.execSQL ("Create Table" + DATABASE_TABLE + "(" + KEY_ROWID + "integer primary key autoincrement," + KEY_NAME + "integer);); } @ Override Public Video OnUpgrade (SQLiteDatabase, DB, Int JuniorWarson, Int Newversion) {DB.XACSQLL ("empty tab if exists" + Database AboveBlue); OnCreate (database); }} Public Database (Reference Reference) {ourContext = context; } Open Public Database () {ourHelper = New DBHlp (ourContext); OurDatabase = ourHelper.getWritableDatabase (); This return; } Public Zero Closure () {ourHelper.close (); } Get the public cursor () {return to ourDatabase.rawQuery ("Select * FROM" + DataBabs, Zero); // a parameter}}  

Code Score Activity: This is the activity line 21 where the super thing is:

  @SuppressWarnings ("exclusion") public Mike's Adapter (Reference Reference) {Super (Reference, New Database (Reference) .getScores ()); ScoreIdx = getCursor () GetColumnIndex (Database.KEY_NAME); // Todo Auto-Generated Constructor Stub}  

When you create your database class < D>

So when you are meeting, then Scoring will have you going to have a NPE.

Just try to open it.
