Is it possible to prevent user from uninstalling application in Android?
Thanks in advance for paying attention on this problem…!!
Is this possible to install an application that no one can uninstall it. I just mean that by going
setting --> Apps --> Manage Applications --> by selecting an app and click on UnInstall.
I want that If I install an application in a device, then no one can uninstall it.
Yes, it’s possible. You just have to write/modify your own custom rom. If you’re in a large corporation/organization. Your corporation/organization may want to have its own rom for its own employees’ company-owned phones.
Or if you’re in the consumer space, the other option is to convince a cell phone carrier to make your app a default one (and to prevent the user from uninstalling it). This is not a technical challenge. It’s just a commercial one. Be prepared to pay them lots of money to have you installed by default on their phones.
And be prepared for some serious backlash in your ratings in the Google Play/Market. Two years ago, I was incredibly frustrated at having the NASCAR application on my phone, that I couldn’t uninstall (despite the fact that I couldn’t care less about NASCAR), and of course, I wasn’t the only one. The app’s rating went down to 1 star because of this and created lots of ill-will towards NASCAR.
