How can we integrate our Android apps to publish data to Google Plus Walls. If someone knows how to do this, provide me an API and sample code for publishing data on google plus wall using an Android app.
The Google+ API is currently read-only. It does not support write operations (e.g. publishing).
Refer to this link, google provide the API for google + in beta, using this, you can post messages to google +,
