I am parsing a HUGE xml which contains nearly 20000 tags, I am saving all the entries from the xml into my sqlite database as soon as i am parsing them.
But apparently xml is getting parsed pretty quickly without insert operation, but when i try to insert each values it takes very long time.( Around 10 mins).
Database insert code :
for (int i = 0; i < tracksList.size(); i++) {
dataSource.addTracks(tracksList.get(i));
}
public long addTracks(Tracks tracks) {
long insertId = 0;
ContentValues values = new ContentValues();
values.put(TRACKS_ID, tracks.getStrId());
values.put(TRACKS_ARTISTID, tracks.getStrArtistId());
values.put(TRACKS_ARTISTNAME, tracks.getStrArtistName());
values.put(TRACKS_ALBUMNAME, tracks.getStrAlbumName());
values.put(TRACKS_FILENAME, tracks.getStrFileName());
values.put(TRACKS_TRACKNAME, tracks.getStrTrackName());
insertId = database.insert(TRACKS_TABLE, null, values);
return insertId;
}
Is there any alternative to get each element from my arraylist and save them with much better speed.
EDIT : Got it working, thnx all..
database.beginTransaction();
try {
//standard SQL insert statement, that can be reused
SQLiteStatement insert =
database.compileStatement("insert into " + TRACKS_TABLE
+ "(" + TRACKS_ID + "," + TRACKS_ARTISTID
+ "," + TRACKS_ARTISTNAME
+ "," + TRACKS_ALBUMNAME
+ "," + TRACKS_FILENAME
+ "," + TRACKS_TRACKNAME + ")"
+" values " + "(?,?,?,?,?,?)");
for (Tracks value : tracksList){
//bind the 1-indexed ?'s to the values specified
System.out.println(value.getStrId());
insert.bindLong(1, value.getStrId());
insert.bindString(2, value.getStrArtistId());
insert.bindString(3, value.getStrArtistName());
insert.bindString(4, value.getStrAlbumName());
insert.bindString(5, value.getStrFileName());
insert.bindString(6, value.getStrTrackName());
insert.execute();
}
database.setTransactionSuccessful();
} finally {
database.endTransaction();
}
Use one transaction for all inserts, otherwise you get the storage synchronization overhead for every single insert:
