Say I have multiple .apk files. Is it possible to combine all these into one .apk file for the convenience of the end user?
You have to include either package or activities into the single project and these activities must be connected with each other in some way as there would be only one main activity defined in manifest file. So, it must be in the sequence in which you want to show. That's it and otherwise i don't think it gets happen through any other way ........... :)
