Q:

ActivityGroup start 3rd party Activity.

Hi guys,

I'm trying to make an ActivityGroup which has it's own interface, which should be persistent between Activities.

I have it working for my own Activities. But when I try to launch a 3rd party activity (from it's Intent{action="ACTION_HOME", category="CATEGORY_LAUNCHER"}) I get a java.lang.SecurityException because the Activity I want to start does not have the same UID as the calling Activity. Does anyone knows how to cirumvent this?

What you want is not possible in Android, for security reasons, as the error message indicates.

Yeah, I was afraid this was going to be the answer. Thanks for your response.Might I ask: why would this be a security threat? I still don't have special access to the Activity, do I? (Hmm maybe I have access to the onSaveInstanceState() bundle, so that I could do some bad stuff, but otherwise?)

It's more that Android does not have support for two things on the screen at the same time from multiple processes. Android wants to keep the applications in separate processes for security reasons. Hence, the `SecurityException`. It is conceivable this will change someday, but past discussions on this topic on the Android firmware groups makes it seem as though changing this will not be easy.
