Question

To populate my database, I have some loops like that:

for (int i=0;i<something;++i){
   myDatabase.insert(...);
}

But when I run it, it takes a too long time. So I’d like to know how to improve the runtime?
I’d try to make a only one call to insert like that:

String queries="";
for (int i=0;i<something;++i){
   queries += "my query;";
}
myDatabse.execSQL(queries);

But the execSQL function insert only the first query, not others.
So how can I do?

You should exec all requests through one transaction:

db.beginTransaction();
try {
    ...
    db.setTransactionSuccessful();
} finally {
    db.endTransaction();
}
