I'm trying to pre-populate an Android SQLite database using ORMLite. The problem is that this operation is too slow. It takes several minutes. The code below show how it happens.
RuntimeExceptionDao<Company, Integer> companyDao = ORMLiteHelper.getInstance(context).getCompanyRuntimeDao();AssetManager am = context.getAssets();
try {
InputStream instream = am.open("companies.sqlite");
if (instream != null) {
InputStreamReader inputreader = new InputStreamReader(instream);
BufferedReader buffreader = new BufferedReader(inputreader);
String line;
try {
while ((line = buffreader.readLine()) != null) {
//Log.i("SQL", line);
if (line.startsWith("INSERT INTO Companies")) {
companyDao.executeRaw(line);
}
}
} catch (Exception e) {
Log.i("SQL", e.getMessage() + " " + e.getLocalizedMessage());
}
}
} catch (Exception e) {
Log.i("SQL", e.getMessage());
}
Where companies.sqlite is a file with tousands of lines of inserts like this:
INSERT INTO Companies (id, name) VALUES (1, 'Duff Beer');
I'm using a DatabaseConfigUtil class to avoid the use of annotations.
Use a database transaction. See here and TransactionManager. Something like:
TransactionManager.callInTransaction(connectionSource,
new Callable<Void>() {
public Void call() throws Exception {
// Your code from above
}
});
