On Android devices, it's possible to set an app (by its android package name) to launch when the tag is read.

int setLaunchApp(const char* androidPackageName);

Note that all of the set options are mutually exclusive. Calling NFC.setLaunchApp() will clear any NFC.setText(), NFC.setUri(), etc..

This does not do anything on iOS. An NFC-aware iOS app can read the package name, but in general won't be able to do much with it.
