多次写入android sqlite3

Question

How can we write simultaneously multiple time in sqlite3 database in android if I am performing a database operation from an activity and at same time if my android service starts (Which also perform database insertion) then how to handler the database operation.

as android developer website says http://developer.android.com/reference/android/database/sqlite/SQLiteDatabase.html#setLockingEnabled%28boolean%29

that SetLocakingEnabled " method is deprecated ". So how we can access multiple write(insertion) operation in Database.

I also referred to the documentation of sqlite for locking http://www.sqlite.org/faq.html#q5

please provide any example for the same .

Thanks

I'm not sure what you mean by multiple write access. But what you probably want to do is lock the database with a transaction and perform your inserts, then when complete end the transaction.

//in your database access class...assuming you have a list of objects to insert

public function void multiple_write(ArrayList<Object> list) {
  //this locks the database
  db.beginTransaction();
  for (Object obj : list) {
    db.insert(TABLE_NAME, null, getContentValues(obj));
  }

  db.setTransactionSuccessful();
  //this completes your transaction
  db.endTransaction();
}
