Good afternoon staff, following, developed 02 apps I am compiling them as Release (obfuscated). When I install the two on my device whenever an app disappears and when I install it disappeared the device of such a message: You want to install an update to this existing application? My perguna is to exist if it does not appear on the device ?? It seems that ta installing over the other ie ta with the same files, checked over and saw that .apks are different names, what's going on ?? someone has gone through it ... Thanks in advance already ....
