Android Question Install multiple apk's from within an application

I currently download an "installation" zip file containing multiple .apk's and would like to install them all sequentially.
Is there a way to iterate through a list of apk's, install one, then return to the running application, install the next, return to the application... until the list of apks is complete?
Currently, the installation application terminates upon completion of installation intent running the installation process.
Thanks,
Rusty
