1) Change ::
private static final String DATABASE_TABLE="Table";
to another name that is not a SQLite reserved word
for example :: private static final String DATABASE_TABLE="myTable";
2) Inside onUpgrade method add an space in your query:
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
//db.execSQL("DROP TABLE IF EXISTS" + DATABASE_TABLE);
db.execSQL("DROP TABLE IF EXISTS " + DATABASE_TABLE);
onCreate(db);
}
