What if I install an App having Package Name: com.test.
And then install another app having package name: com.test.deeper
Are there any possibilities of these two apps running on same Process Resources?
Two apps can run on same process but in your case it won't be the case.

You just need to assign same values to android:shareUserID and android:process in both applications and sign them with same certificate.
