Outline
– How can you take your app to the next level ?
– What to expect from the final exam ? – Structure
– Model questions and answers – Course outcomes

What’s next for your projects ?
– You can definitely consider publishing your app at Google Play store.
– Submit your app to an app competition
– Do not worry a lot about monetization at the beginning. It will
follow naturally, if your app is trendy.
– Pitch your app to an incubator program
The University of Sydney Page 11

Things to be aware of: Compatibility of Licenses
– See whether just the release of one platform (Android only) will have a significant impact.
– Can you think of example apps (out of the ones developed by you); 1. That must have multiple platforms?
2. That one platform is sufficient at the beginning?
– Every external SDK, Library, Platform, etc. you connect have their terms of services. You need to verify all of them before you publish
– Carefully review your app for licensing incompatibility
– Release your app under the correct license
– Fedora Wiki for Licencing
– https://fedoraproject.org/wiki/Licensing:Main?rd=Licensing
– Examples:
– Apache v2 is not compatible with GPLv2.
– Eclipse Public License v1 is not compatible with GNU GPLv2. – “GPL v2 only” is not compatible with GPLv3 or LGPL v3
– If you use GPL code you will need to make all of the source code for your programs available to the public

You can not combine all open source libs

Things to be aware of: UX-UI Matters !
– Too many lists and form filling in many apps !
– UX-UI is one of the most important aspects of real-world applications
• Google device market is diverse, make sure you test your app in various circumstances and restrict the distribution to what you have already tested.
• Try Google Beta testing
– Learn from user studies. Pick users who honestly evaluate your
product.

Things to be aware of: UX-UI Matters !
– Practice your skills in presenting your idea. – Practice how to do impactful demos.
