Question for ANDROID users!

<p>On your android device, if you have a Google/Gmail/etc app on it which allows you to chat with your Gmail/Google+ contacts, does being “green” signify that you are in the app or does it just show that your phone is on? </p>

<p>The reason why I’m asking is because I’m currently on a desktop and I want to ask someone a question and she’s “green” but she’s on a phone, if she’s in the app itself, I’ll ask her, if not, I’ll wait because I know she probably won’t see it for a while if her phone is just idle/on.</p>

<p>I have the HTC EVO 3D.
I’m pretty sure it’ll say you’re online if you’re in the app. Otherwise it might say you’re idle or offline.</p>

<p>It says you’re online if you’ve last opened the app within a couple of minutes and it’s running in the background.</p>

<p>I thought if you were on a phone a little android robot replaces the normal dot?</p>
