PDFTron full or standard? Which version is for me?

PDFTron library comes in two versions: full and standard.

In order to help our customers to create applications with a smaller APK size, the standard version omits a number of features such as:

Rendering speed and quality are the same for both versions of the library.

The following table compares the APK size of a sample project in which different architecture and PDFTron library versions were used.
