We need a very small demo eclipse project creating to demonstrate fragment swapping - a complete solution with commented code and applicable variable names.
It will need to be built against Android 4.2.2 and have the following:
One main activity implementing a PagerAdapter and ViewPager.
First page - static fragment loaded
Second page - load one fragment with a button within it.
When the button is clicked, the fragment is swapped with another fragment.
Pressing the up button in the action bar should revert back to the first fragment so they can be switched between.
Our first thoughts is that an interface is used and listened to in the main activity containing the fragment management code.
Best practices MUST be used for navigation and transactions should be stored with the Fragment manager. UI is not important - only to demonstrate the principle and for the functionality to work 100%.
Projects should be completed in eclipse.
We require a fast turnaround - 3 days.
Milestone to be paid once a source code project is delivered and the requirement has been satisfied.
