> You said real time graphs, so depending on what that means to you, you might be better off with Java.
OP, if you end up going with Java, use <strong>MPAndroidChart</strong>. It has great performance, is very simple to use (while also providing access to a highly granular set of customization options), and has real-time plotting baked in.
Check out the <strong>Library Demo</strong> on Google Play.
