• Room, database modification without DB recreate

  I have an app with Room DB. I store "started" variant in assets folder, and i realize simple logic: if DB is not created yet or DB folder is empty(first launch), i'm copy "started" DB from assets on DB path, and now i have filled database to work.

  But i have a problem: every database modification seems like hell. Can you explain how to make it easier?

  For example, if i want to add column i cant just update class model on my app, download database with data on PC, added column, up DB version and load it back. If i do this, app will not see my DB and will create empty base. So now i need:

  1. Update model on my class.
  2. Launch application to create clear DB.
  3. Download clear database from my phone.
  4. Add column on clear database.
  5. Fill empty database with data from old base.
  6. Increase DB level on app.
  7. Load new database to assets
  8. Launch app.

  So every time when i need to do smth(rename, add/delete/...), i need to recreate DB by hands. What can i do to avoid this?

• Drag and drop with sprite sheet animation in JS

  I want to create a sprite sheet animation on a drag and drop action in JS. I am trying to achieve that by setting event.dataTransfer.setDragImage to a div with a sprite sheet as background (CSS). Afterwards, I change the background position to get it animated. However, when I start dragging the image I only see the first pose. In the dev tool, I can see how dom element updates. Why is my animation not updated?? What am I missing?

    window.dragstart_handler = function (ev) {
            ev.dataTransfer.setData("text/plain", ev.target.id);
  
            let position = 0;
            let interval = 500;
            var elem = document.createElement("div");
            elem.id = "dragContainer";
            elem.textNode = "Dragging";
            elem.style.position = "absolute";
            document.body.appendChild(elem);
            ev.dataTransfer.setDragImage(elem, 48, 48);
  
            dragAnimationId = setInterval( () => {
              document.getElementById("dragContainer").style.backgroundPosition = `-${position}px 0px`;
              //we use the ES6 template literal to insert the variable "position"
              if (position < 3552) {
                position = position + 96;
              } else {
                position = 0;
              }
            }, interval );
  
          }
          window.dragend_handler = function (ev) {
            console.log('dragend global');
            nodeHitFn(ev);
          }
          // Let's remove the created ghost elem on dragend
          document.addEventListener("dragend", function(e) {
            var ghost = document.getElementById("dragContainer");
            if (ghost.parentNode) {
              ghost.parentNode.removeChild(ghost);
              clearInterval(dragAnimationId);
            }
  
          }, false);
  
  
• How can different animations can be attached to an image dynamically in react-native?

  Asume there is an image on the screen and when a user presses another image (say right arrow) the first image goes right and when the user presses a third image (say left arrow) the first image goes left.

  Briefly something like this, the left arrow should move the stickman to the left and the right should move to the right:

  

  According to the documentation, an image can have multiple animations (transforms, scales, opacity changes etc) but it seems all those animations need to be run parallel (simultaneously).

  My question is about doing this with a function call freely from unrelated objects.
• How to set badge on app icon programmatically?

  I'm trying to set up the badge on app icon if there are some pending notifications. Which works well with the following code in Android Pie.

  notificationBuilder.setNumber(i);
  notificationBuilder.setBadgeIconType(NotificationCompat.BADGE_ICON_SMALL);
  

  But now I need to show the badge if there are any pending unread notifications in the app. The above badge only appears if the notification is present in the notification bar. And once it's dismissed the badge also disappears which is fine but is there any way we can set up badge depending on a count got from firebase?
• How to reuse app icon image using `require`?

  The react native app icons are put in ios\VietVanHocTro\Images.xcassets\AppIcon.appiconset and android\app\src\main\res\mipmap-... folders.

  How can I use these icons in the application without duplicating them?

  Can I use isOS ? require('.../android-icon') : require('../ios-icon')?

  I've tried require('../ios/app/Images.xcassets/AppIcon.appiconset/icon-20.png') but it gives me undefined as the error.
• How do I select app icon based on Locale for iOS10 and above?

  I've been trying to switch between app icons based on the Locale but haven't found a way to achieve this. Tried these following methods, still not working.

  1) Tried using setAlternateIconName which will require for you to open the app before you can dynamically change it - Wont work for me.

  2) Tried moving the app icon from Assets folder to icon.png under resources and then use infoStrings.plist locale file to change the CFBundleIconFile - Still didnt work.

  3) Tried moving the app icon to icon.png under resources and tapped Localize on the icon image itself - That didnt work either.

  Is there any way this could be done?
