Broken images when testing in real devices

ionic-v1

  <ion-side-menu side="left">

    <ion-content>
      <ion-list>

      <ion-item nav-clear menu-close href="#/app/t">
          <img class="sideIcons" src="/img/music.png">Tracks
        </ion-item>

        <ion-item nav-clear menu-close href="#/app/l">
          <img class="sideIcons" src="/img/love.png">Saved
        </ion-item>
        
      </ion-list>
    </ion-content>
  </ion-side-menu>

I try to put images as li for my sidemenu. I debug using real device with ‘ionic run android’ but my images were broken. Strange thing is other images are fine. Above code is the sidemenu template. I can see the images when I use ‘ioinic serve’ in browser.

1] Images are relative to www directory, ensure that.
2] I solved this issue by adding ./ to path eg. ./img/love.png
