Efficient method to access data across activities

I have a small app that records messages and stores them in an object which implements Parcelable. In the app I have a LOT of messages (about 2000) and it takes a considerable amount of time passing between Activities through intent.putParcelableArrayListExtra

Is this not the correct usage of Intents+Parcelable? I've been really wanting to avoid开发者_Python百科 SQLite, but I suppose I'll get my hands dirty if its absolutely necessary.

You should definitely persist your messages in a database. If you want to avoid all the SQLite hassle check db4o, painless object persistence in your apps using an OODB.
