What is Nodpi in Android?

nodpi : Resources for all densities. These are density-independent resources. The system does not scale resources tagged with this qualifier, regardless of the current screen's density.

What does Nodpi mean?

Android Studio exposes developers to -nodpi and -anydpi in various places. For example, if you use the New Resource Directory wizard thing, and you choose to add a density qualifier to the directory, you will see "No Density" ( -nodpi ) and "Any Density" ( -anydpi ) options.

According to this document there is no "Added in API level X" below nodpi. So it must be supported by all platforms.
