Can I have an application always open on Android?
<p>I don't know much about Android multitasking but I thought I'd ask the question before I attempt my project.</p>

<p>Is there a way I can program an Android application (aimed at Android 4.0+ only) to always be open in the background and keep all the network connections alive and the UI "drawn" so that when I open it, it ALWAYS opens instantly and I can use it instantly even if the tablet is doing something else?</p>

<p>Thanks.</p>
