android unable to use hdmi in creative tab and need to be notified in all(maximum) devices as soon as hdmi is plugged

Question

may be possible duplicate of hdmi support in android.

I am working on XYZ video encrypted app.But need to manage hdmi also to overcome the encrypted video pitfall.

As per my search I found that these are not in official docs and are provided by specific vendors Api as that of Motorola.

I have explored much and found that these are vendor specific , there is no unique api or documentation to serve the needs of all the devices.

My device is:

Creative ziio 7 OS :2.2.1 build number:v2.00.13-FROYO.

But please suggest and answer the following via the google white papers or your personal experience:

• If a certain android device has hdmi hardware support, then how can we detect it programmatically.

• If the hardware is supported in device. Then if the connection is made to hdmi my app need to be notified about that.
  (like using a recevier etc).

• I am also unable to connect the hdmi in Creative ziio 7 with hdmi cable (AWM 1.3 cable) to my hp notebook pro laptop

I have noticed about that certain vendors provide hdmi api like MOTOROLA http://developer.motorola.com/docs/motorola-hdmi-status-api/

Also we can detect the USB Plug Status in all devices by using

 <action android:name="android.intent.action.ums_connected" />

So is there any way for hdmi also. But need to have a general concept to do the same for all devices.

Answer 1

Although there does not appear to be an official standardized way of doing without using vendor specific APIs, on later versions of Android 3.0+, it seems like the Android source code references a broadcast action intent that most vendors seem to be implementing. This intent is "android.intent.action.HDMI_PLUGGED". If you're targeting these later OS versions, this seems to be pretty reliable from my experience in detecting when HDMI is connected.

Answer 2

As far as I know, there is no HDMI support inherently in the platform. Each hardware vendor hacks up their own implementation via the hardware composer hardware abstraction layer. Meaning, there isn't a way for you to programmatically interact with anything HDMI related with the standard Android SDK.
