问题
I am developing two android apps with android studio and for some reason I want just one of these apps can be installed on a device. I think I should check the package name of second app and prevent it from installing. Is there any way to do that? thanks.
回答1:
You can not prevent any app from being installation. Instead you can stop your app from being running. I mean, when your app starts, check if specific application is installed, and if so stop your application.

An ordinary app cannot prevent another app from being installed. Malware authors would think that such a "feature" would be wonderful.
Device owner apps — mostly for IT departments at larger organizations — have some abilities here, though I forget whether they can block installation by package name.
