.apk cannot be opened by P5 “as it is”; you have firstly to decompile it and find the source; then you can open it withP5 android mode. As for decompiling if you unzip an .apk you will get all the res that are used, the manifest but not the code; in order to decompile the classes it depends of your system, but anyway decompilers exist for MAC, UNIX && WINDOWS
