How to open android's apps activity
<p>I've been searching and I couldn't find a topic that could clarify me 100%.</p>

<p>My question is: How can I open an android's app specific activity (like Contacts, Messages, ...) on my own app?</p>

<p>I give an example:
Imagine I'm developing an app which allows the user to quickly access to Message's Settings. I don't need to send or receive any information, I only need to open the activity.</p>

<p>Someone knows if this can be done and even opening specific locations of the apps?</p>
