SQLite - Speed up 4,000 row insert in Android app

public synchronized void updateStop(ArrayList<StopBean> beanList){
    SQLiteDatabase db = getWritableDatabase();
    String query = "DELETE FROM 'stop'";
    db.execSQL(query);
    for(StopBean bean : beanList){
        String atco_code = bean.getAtco_code();
        String name = bean.getName();
        String locality = bean.getLocality();
        String bearing = bean.getBearing();
        String latitude = bean.getLatitude()+"";
        String longitude = bean.getLongitude()+"";

        ContentValues values = new ContentValues();
        values.put("atco_code", atco_code);
        values.put("name", name);
        values.put("locality", locality);
        values.put("bearing", bearing);
        values.put("latitude", latitude);
        values.put("longitude", longitude);
        db.insert("stop", null, values);
    }

    db.close();
}

Currently our application inserts 4,000 rows via the method above. The problem with this method is that it takes 10-15 seconds to actually execute. Clearly this is far too long for a simple 4,000 row insert.

How can I change this method so that it vastly speeds up the execution time of these inserts?
