How do I use the categories option of the monkey tool?
The relevant portion of my manifest file looks like this:
As far as I can understand by looking at the Monkey source code is that the -c argument stands for "main-category", it will only work in combination with a main-action. That the -c/main-categories criteria will only work when the monkey tries to start the app with "Implicit Intents" and not "Explicit Intents" within the app.
