We are developing an android application which is to be installed on the ~500 devices in the premises.How can I do it centrally at one go via wifi network.
Thrice every quarter, the following is required
I know on device we can set "allow unknown sources" by default. But is it possible to push/install the application (like the ICS push on the Ginger Bread Mobile Phone recently)
I have gone through this post but no precise answer.
For the initial install, you can't. You have no choice but to manually install the app by one means or another (e.g., download it via a link from your intranet).
For updates, the app can check for an available update, download it, and then initiate an install when the user is ready. You cannot forcibly upgrade the app though -- the user will have to be involved.
You also cannot "installed (upgradable version)-uninstalled (older version)" except by hand -- once the app is uninstalled, it has no way to trigger installation of some other app. Also, by uninstalling, you lose all your data, which is generally frowned upon. Upgrading in place is the more typical approach.
