Answer 1

I believe you are inserting 1000 or 10000 using a loop. Use TRANSACTIONS , it will dramatically reduce the write time. I already encountered such an issue and it reduced the write time in my case from around 30 seconds to about less than 1 second.

Take a look at this.

Basically, what you should do is :

db.beginTransaction();
try{
    for(int i = 0 ; i < LENGTH ; i++ ) {
        // execute SQL
    }
    db.setTransactionSuccessful(); // marks a commit
    }
finally{
    db.endTransaction();
}
