What qualifies Android Display?

In API 17, Android introduced the ability to present content on additional displays. They say that content can be displayed on any display connected to the device via a wired connection or Wi-Fi. You can even get a list of connected displays with the DisplayManager class. What I want to know is what matches the Android display? What types of devices can be used as secondary displays using the DisplayManager class?

What I want to know is what matches the Android display? What types of devices can I use as secondary displays with the DisplayManager class?

It depends on the device manufacturer. Some devices support HDMI output through some kind of connector (micro HDMI, MHL, etc.). Some devices support Miracast. And so on. From the point of view of Android, they will become a monitor. Regardless of whether they are an LCD monitor or a TV or an HDMI recorder, or something else before the manufacturer of this equipment.

Please note that not all devices with Android 4.2 and external display support support Presentation for these external displays. For instance:

  • Nexus 4 supports Presentation via Miracast
  • Nexus 10 supports Presentation via HDMI
  • Galaxy Nexus does not currently support Presentation via MHL
  • ASUS Transformer Infinity does not currently support Presentation via HDMI
