I would like to require that a user type a password before being allowed to uninstall/remove my application. How can I implement this functionality? Spintires free download pc game full version.
If you turned on Touch ID or Face ID for iTunes Store purchases, you won't be prompted to set your password preference. Touch ID or Face ID will always override whatever preference you set. If you have either turned on, you're prompted to authenticate every download.

You could do this by:
- The first time your app is installed, install a separate application/package ('watcher').
- The only classes 'watcher' contains is a BroadcastReceiver that listens for
ACTION_PACKAGE_REMOVED - Add a BroadcastReceiver to your application that also listens for
ACTION_PACKAGE_REMOVED - When a intent is broadcast to one of your receivers, check if the other component is still installed. If is isn't (the user just uninstalled it), prompt for the password - if it's wrong, reinstall the other component. If it's right, uninstall yourself.
You can exec logcat and get the start activity intent information.You will find that before the uninstall activity is displayed, there is a text msg such as:Starting activity: Intent { act=android.intent.action.DELETE dat=package:com.comodo.pimsecure cmp=com.android.packageinstaller/.UninstallerActivity }then you can pop a activity ask for password now.
This is a hard problem. I can think of at least one non-evil use-case for it.
e.g. Stolen Phone Recovery app - you wish to deter ne'er-do-wells from uninstalling the app.
In this case, I can think of two sensible assumptions which would stop me implementing what you're looking for:
- the thief is unaware of your app, so will not try to uninstall it.
- the thief is aware of your app, and switch it off until he can get it to an iron box
*to re-install the OS.
* For the uninitiated: an iron box will prevent the device sending or receiving electromagnetic signals.
Of course, this answer amounts to You Ain't Going To Need It, though I suspect you have already thought this through.
It is possible. you can do it with DeviceAdminReceiver api. (i don't no how)

How it works:
For the most part, keeps the tempo breakneck and the intensity numbing throughout her set, throwing down one record after another. Never subtle, gets down to business immediately on, her 2002 mix for Surge Recordings. Dj irene phonosynthesis download torrent. Since her business is hard and wild dance music, you nearly feel whiplash when the hardcore-like percussion begins hammering on 'Acid Eaterz,' the second of 29 tracks featured in the mix. Flies through one track after the other, all of them hard and wild, and most of them quite provocative and sexual.
