Question

I am saving some data in a database using asynctask with a loop like this:

for(int i=0;i<5;i++){
new Loader().execute(i);
}

and in my asynctask class the doinbackground method is like this:

@Override
        protected Void doInBackground(Integer... params) {
            db.insert(params[0]);
            return null;
        }

its being executed but everytime its inserting the first value of i in the database? how to work it with corresponding this loop?

Answer 1

You can do something like:

    @Override
    protected Void doInBackground(Integer... params) {
        int count = params.length;
        db.beginTransaction();
        try {
            for (int i = 0; i < count; i++) {
                db.insert(params[i]);
            }
            db.setTransactionSuccessful();
        } finally {
            db.endTransaction();
        }
        return null;
    }

and you call new Loader().execute(1, 2, 3, 4, 5);

You save memory by creating only one AsyncTask object instance
