In any case, we do have an exceptionally solid instrument, that can help our Android Application speak with a database, and this is SQLite. SQLite is an Open Source Database for organized information in social databases. It is implanted in Android, to you don't need to do anything unique to set up or control a SQLite server.

private void myMethod () {

Cursor c =

SQLiteDatabase db;String sql;

db.rawQuery(sql, invalid)

SQLiteDatabase database;String table;

database.query(table, invalid, invalid, invalid, invalid, invalid, invalid)

Setting mContext;Uri uri;

mContext.getContentResolver().query(uri, invalid, invalid, invalid, invalid)

The fundamental motivation behind a cursor is to point to a solitary line of the outcome gotten by the inquiry. We load the column pointed by the cursor object. By utilizing cursor we can spare part of slam and memory.
