How to make WiFi higher priority than Ethernet on android?

 1. Android 9

frameworks/opt/net/ethernet/java/com/android/server/ethernet/EthernetNetworkFactory.java

/**

 * {@link NetworkFactory} that represents Ethernet networks.

 *

 * This class reports a static network score of 70 when it is tracking an interface and that

 * interface's link is up, and a score of 0 otherwise.

 */

public class EthernetNetworkFactory extends NetworkFactory {

    private final static String TAG = EthernetNetworkFactory.class.getSimpleName();

    final static boolean DBG = true;

    private static final int NETWORK_SCORE = 59;// fix to lower score than 60.

2. Android 11

frameworks/opt/net/ethernet/java/com/android/server/ethernet/EthernetNetworkFactory.java

        private static final SparseArray<TransportInfo> sTransports = new SparseArray();

        static {

            // LowpanInterfaceTracker.NETWORK_SCORE

            sTransports.put(NetworkCapabilities.TRANSPORT_LOWPAN,

                    new TransportInfo(ConnectivityManager.TYPE_NONE, 30));

            // WifiAwareDataPathStateManager.NETWORK_FACTORY_SCORE_AVAIL

            sTransports.put(NetworkCapabilities.TRANSPORT_WIFI_AWARE,

                    new TransportInfo(ConnectivityManager.TYPE_NONE, 1));

            // EthernetNetworkFactory.NETWORK_SCORE

            sTransports.put(NetworkCapabilities.TRANSPORT_ETHERNET,

                    new TransportInfo(ConnectivityManager.TYPE_ETHERNET, /*70*/55));

RAW Image editing with ODROID-N2

PC 없이 RAW 파일 편집하기
Editing RAW Images without PC.

DSLR을 이용해서 RAW 파일을 편집하려면 많은 사람들이 Windows가 설치된 PC에 포토샵이나 라이트룸을 이용한다.
Many people used Photoshop and Lightroom to edit their RAW Images with PC installed Windows.

하지만 나는 스마트폰에서 Snapseed만 이용해서 RAW파일 편집을 해왔다.
But I only have used Snapseed app on Android smartphone.

하지만 화면도 작고 브러시 기능을 이용할때는 터치로 작업하기에 불편하다.
But it is to hard to edit because smartphone has a small screen and if you want to use brush tool, you will feel difficult to edit accuratly.

그래서 큰 화면의 TV와 ODROID-N2에 마우스를 연결하면 PC처럼 편집을 시도해 보았다.
So, I have tried to use android ODROID-N2 connected mouse and TV like a PC.

1. USB C-Type OTG adapter 를 이용하여 RAW 파일을 카메라에서 스마트폰으로 옮긴다.
최근에 새로운 스마트폰을 샀다면, USB C-Type OTG 어뎁터가 패키지에 포함되어 있다.
First you can move your RAW Images to your smartphone with USB C-Type OTG Adapter.
If you buy a new smartphone recently, it was included in smartphone packages.

2. 스마트폰으로 다 옮기고 Google Photos 동기화 한다.
After moving files and sync with Google Photos.

3. ODROID-N2에 Google Photos와 Snapseed를 설치한다.
Install "Google Photos" and "Snapseed" on ODROID-N2.

4. 마우스를 ODROID-N2에 연결한다.
Connect a USB mouse.

4. 편집하고 싶은 사진을 "기기에 저장"
Save a RAW image that you want to edit.

5. 편집 앱을 Snapseed를 선택한다.
Click to edit icon and select Snapseed.

6. 터치 없이 마우스로만 큰 화면에서 편집이 가능합니다.
You can edit images by using mouse, it is easier and more accurate than using touch screen.

ODROID-N2 2GByte 모델이지만 무리 없이 편집이 가능하다.
I have the ODROID-N2 2GByte momory, But it works well smoothly.
