Is there another way to access application data? Yes.

Is it better? Depends on what you define as better.

Can you detail your use case a bit more, and discuss why you're looking for an alternative to RPCs?

i am considering a new app. there is no determined use case now. i would make up my mind after comparing all the ways.

Choosing the best way to access data depends on the use case, so it would probably be better to figure out the use case first. Nevertheless, since you asked for alternatives:

1. Write a simple REST API to access and modify the app data. Probably the best solution since you can customize the API to emit and accept data using your preferred syntax (JSON or XML, etc). http://stackoverflow.com/questions/19357298/what-is-difference-between-web-service-and-rpc

2. Assuming the app you want to access is on App Engine, you can directly connect with the Remote API and use resources under the application's name: https://developers.google.com/appengine/docs/java/tools/remoteapi 

3. Again assuming the app is on App Engine, you can access the different persistent data services directly. For instance, the datastore can be accessed through the Cloud Datastore service: https://developers.google.com/datastore/docs/getstarted/start_java/ . The Cloud SQL and Cloud Storage services can also be accessed by different applications by whitelisting their IDs.
