Description

1、接收广播

    private final BroadcastReceiver HdmiListener = new BroadcastReceiver() {
        @Override
        public void onReceive(Context ctxt, Intent receivedIt) {
            String action = receivedIt.getAction();
            String HDMIINTENT = "android.intent.action.HDMI_PLUGGED";
            if (action.equals(HDMIINTENT)) {
                boolean state = receivedIt.getBooleanExtra("state", false);
                if (state) {
                    Log.d(TAG, "BroadcastReceiver.onReceive() : Connected HDMI-TV");
                } else {
                    Log.d(TAG, "BroadcastReceiver.onReceive() : Disconnected HDMI-TV");
                }
            }
        }
    };

2、节点判断

HDMI1
/sys/devices/platform/display-subsystem/drm/card0/card0-HDMI-A-1/status

HDMI2
/sys/devices/platform/display-subsystem/drm/card0/card0-HDMI-A-2/status

DP同理，card改为DP对应的
