java - Android Realm large file size

Question

I am new to android programming. I implemented Realm for my simple grade tracker, however, the file size has grown from 1.5mb to 5mb. Is that normal?

What I simply did was add in an instance of realm on every class with oncreate, added in realm.close() whenever there was a chance that the activity would end. Also wrapped the begin and commit transaction around each object creation.

Is there something I did wrong that ended up with the massive file size?

Thanks!

Edit: I mean apk size

@geisshirt is right. Realm have introduced the method public static boolean compactRealm(RealmConfiguration configuration) to compact the realm database. Calling this method reduced the size of my database from +350MB to <1MB
