Is any system Android API request to check if some "app.package" is installed ?
Without need to get firstly all packages list of the device, that is sloooow way.
Thanks, Don. I just remember that long ago used such search, and seems, there was no way without getting the whole list firstly. Maybe i remember wrong...
Indeed, Erel, i have remembered now - the process is slow, if each package name is processed anyhow.
The list itself is got fastly: 300 ms for 170 apps.
Thanks for help.
