App Inventor is a powerful tool to create apps for Android. After having the package in .APK, we can distribute it to friends, customers or other persons. But the main problem : How could i be the only person to install my apps in my friends' phones. How could i avoid that they share or distribute my app ?
NB : I shall use Google Play later
Thank you for your assistance
App Inventor est un outil puissant pour développer des applications. après avoir compacter l'application sous format .APK, nous pouvons le distribuer (l'installer ) dans les téléphones des amis, des clients ou d'autres personnes. Comment puis je être la seule personne à leur installer mon application dans leur smartphone ? Comment puis éviter qu'ils distribuent, partagent ou installent l'application dans d'autres téléphones ?
NB : Je compte utiliser Google Play plus tard.

everybody will be able to install the apk file
thank you for the useful post. how could we create this kind of password to be used only for the first run of the app ? Do you mind, this method could help protecting the app of hacking ?

See attached for a simple scheme, which depends on its initial unlock for you to be there, knowing the formula involving the day of month and hour of day to generate the secret changing unlock code.

By the way, don't tell any one the formula.
And change the formula to something more private, since your enemies might read this post.
