I am developing an android application based on One Drive, using the Live SDK. I am stuck on how to get the available and free space for each user.
From REST, you can get quota and available space for the current signed in user with (details here)
GET https://apis.live.net/v5.0/me/skydrive/quota?access_token=ACCESS_TOKEN
which returns JSON
{ "quota": 26843545600,
"available": 26805319016 }
So, for Android, based on this reference you can probably just use something like this for this GET call
client.getAsync("me/skydrive/quota", new LiveOperationListener() {
... });
