In this way, it can affect both the sender and the recipient on the victim’s smartphone through malware.

It is at this time that these files can be accessed as they belong to a public directory to which another application may enter. Something that does not happen especially when you use an internal storage system.

In case the dependency is necessary for the application to run, it ought to be a manufacturing dependency. For most applications, Indirect dependencies compose the greater part of the general list.
