DRA756: Multi screen Android

Arun Dasari
Intellectual 310 points
Part Number: DRA756


Hi,

I am working on DRA756 board, flashed with Android Marshmallow. There are 2 displays connected to the board(LCD and HDMI). 

current scenario, screen mirror happening: If i open any application same is getting mirrored on both the displays.

I want different applications to be run independently on each display.(example: video playback on LCD and google maps on HDMI )

Any help will be highly appreciated.

Thanks,

Arun

    Hi Arun,

    By default in our SDK we do mirroring on second display.
    If you want different content on the secondary display, you have to write app using Presentation mode of Android.

    There is a API demo app available in Android you can use to test presentation mode.
    It's called ApiDemos and  is available in $MYDROID/development/samples/ApiDemos location.

    Once you lauch this app, you can test presentation mode by going to App --> Activity --> Presentation. Here you will see different content in LCD and HDMI.

    Hi Vishal,

    Thanks for the reply.

    >>If you want different content on the secondary display, you have to write app using Presentation mode of Android.
    My APK is based on Qt framework. I am using Qt creator to develop the APK and installing in Android Marshmallow. Any idea how to avoid screen mirroring in this scenario.

    Thanks,
    Arun

    Hi,

    For system running Android only, presentation mode is the way to go for creating different content on secondary screen.
    You will have to figure out how you can use presentation mode with Qt environment. This is out of scope of our SDKs.
