Your IT staff may wish to prevent accidental or purposeful removal of the aGENDA application. Unfortunately, Android does not allow us to simply block the deleting of applications alone. Described below is a workaround that ensures a passode be entered before installing or removing an application.
We are using an application called "Smart App Protector" by a group called SpSoft. It is a free application which can make it possible to prevent launching selected applications until the user enters a passcode.
Since every device is different, there may be more or fewer applications that need to be locked in order to prevent this. Please test your device thoroughly afterwards to ensure the best results.
Here is how to install and configure the application on a Samsung Galaxy Tab.
When installing it will present you with a list of permissions the application requires, simply hit "Accept" in this screen.
This application is protected, so you must enter a passcode. The default is 7777.
From here we can change the passcode and hint. We can also add applications to lock.
We'll change the passcode and hint first.
In the list that appears is an option labeled "Password" and you will receive this box. Enter a new password. A good suggestion would be to use a different random key per device, but this will be more difficult to manage. The passcode is not limited to 4 numbers.
This will be seen by the user. It would not be advisable to include the actual passcode here.
Once the passcode and hint are changed, return to the main screen using the back button. Then tap on the Add button.
The recommended list of apps is a good starting place to prevent uninstallation. Make sure there are green checkmarks next to Package Installer, Settings, and Task Manager.
Scroll down in the list and location the Play Store. Locking this will insure new applications cannot be installed as well. Click Add when done.
You should test that the application locks are in place by attempting to uninstall an application. You can do so from inside the Settings application, which should ask you for a password. Then in Applications > Manage Applications you can select an application and remove it.
