MHL connection trigger

[zr2ee]

As many people are starting to use their devices in their vehicles with headunits supporting mirrorlink and other mirroring technologies i think it would be good to add a MHL connection trigger as to distinguish between standard external power and power with audio video output.

I'd like to have this trigger too. Also, new high-end USB-C video output trigger too (displayport).
For Mhl technology this could help: https://stackoverflow.com/questions/864 ... in-android

On many phones, the Mhl connection usually triggers the display of a notification in the statusbar (by some system app), so this could be used as a workaround in the meantime
Thanks

5 years have passed, and I still can't see this feature to become mainstream. Since it is quite niche, probably it won't get priority to be added soon. You can always use Trigger General Broadcast : android.intent.action.HDMI_HW_PLUGGED
It is basically the same. For some other event, we can also use this trigger as long as we know the exact broadcast intent of the event.
