User interface and selective sync in google drive / google spreadsheet

Question

Hi I am new to android development and planning to develop a spreadsheet application, which should allow the user to

1) Create and edit a spreadsheet file in local device
2) Have file level control to allow/disallow syncing with google drive. Google credentials could be asked only if the user is interested in syncing.

My questions are:
1) Does google Drive/ Google spreadsheet provide any APIs for user interfaces? What will be the best way to implement the user interface?

2) Is selective syncing possible using google drive / google spreadsheet API?

Answer 1

Yes you can. Google providing API for this. Kindly check this google developers link for more information. I hope you are familiar with designing of spreadsheet like layout and all in your app. If that thing is achieved, you can do it this also by putting small effort.

Answer 2

The two spreadsheet api are: google-apps-script and google-spreadsheet-api ...

Google apps script has good docs and is of good quality, but I suspect google-spreadsheet-api will be a better fit for android development, but depends on your needs.

The google CellDemo.java demo gives a good overview of the spreadsheet api. https://code.google.com/p/gdata-java-client/source/browse/trunk/java/sample/spreadsheet/cell/CellDemo.java

There is also ethercalc - it is a web based spreadsheet, good quality, all open source.
