No.  An .apk is a file which is a container for many kinds of information.
Valgrind tools instrument the instantiation of a process, and not a container.

The "hook" for valgrind, the place where valgrind intercepts control
and begins co-execution of the valgrind tool with the target program, is execve().
execve() is an very clean interface.  The operating system discards entirely
the old memory image, and instantiates a new memory image "from scratch."
This cleanliness is essential for the valgrind tool to identify and
understand easily the initial state of what is being instrumented.
