I want to develop an Android application which uses two screens to display information. For example: One screens shows the app, the other screen some information about the current app status.

My question: Does android support two monitors/screens? How would you build up such a device and project?

From API level 17, android supports this

Here is the link https://developer.android.com/reference/android/app/Presentation

It is now possible for an APP to independently draw different content on primary and secondary displays. Secondary displays can be an HDMI screen or a wireless display.

Some devices do. For example the HTC Evo has a micro-HDMI output that you can send to a TV but the functionality is not built into the Android core so you would need to use the proprietary extensions.

You can only do it using widgets. There is no other way. I have researched on this and there happens to be lot of problems. One company has successfully done it but they could not port two opengl instances.

Look at Kyocera Echo and Dual-screen SDK for Gingerbread!
