I chose Mixing decided, which gecodet well, but less well documented is. Is it very easy to own data or Wikipedia to put data on the camera and simultaneously view the same data as on Google Maps markers.
Vuforia to appear for the development of Android / iPhone solutions of suitable Kanditat be, However, when required under the license, that user data to the Qualcomm server are sent and the user must be informed:

A handy library for Android apps is Acra (Application Crash Report for Android), so can register to an error on the phone of a user sending the message as:
Google Docs spreadsheet (default)
own HTTP POST Server Script
any other possible processing by implementing your own “report senders”
In case of a Crahs can meet the user in the following ways with the error:
Silent (default): ACRA actions are not visible. The crash report is sent and then the default android crash system does its job (Force Close dialog)
Toast: When the crash occurs, ACRA displays a toast and simultaneously sends the report.
Notification: An optional toast is displayed on application crash, but the report is not sent immediately. A status bar notification is published warning the user that he should send a report. When selected, the notification displays a dialog asking for the authorization to send the report, with an optional user comment.
Dialogue: since 4.3.0b1, experimental, allows to display a crash dialog without the need of a status bar notification.
