Question

I am starting to write an Android application that is going to be a reference utility.

As of the moment I am organizing the activities into packages so I would like to write a class that will list the activities in the package to the view to establish the hierarchy.

I do not know know how to ask a package for that information.

Any ideas of how to accomplish this? Tips for a better application design?

Thanks.

Its pretty straight forward if you look at the PackageManager Docs.

Here are the rough steps:

Use Context.getPackageManager() to get an instance of PackageManager.

Then call PackageManager.getPackageInfo() on the desire package. That will return an ApplicationInfo object which has a public member ApplicationInfo.ActivityInfo.

ActivityInfo is an array of all the <activity> tags from the AndroidManifest.xml file.

If this isn’t clear read the PackageManager docs and then follow the links until you get to PackageInfo
