Hello,

which icon are you using custom images or builtin icon of ionic ?

if your have using custom image icon then change image path,
like:
if existing image path is “…/…/assets/images/logo.png” change it with “./assets/images/logo.png”

I am using ionic builtin menu icon.

<ion-header>
<ion-navbar >
  <ion-title></ion-title>
  <ion-buttons end>
    <button menuToggle ion-button>
      <ion-icon name="menu"></ion-icon>
    </button>
  </ion-buttons>
</ion-navbar>
</ion-header>

Chrome Inspector can be used to debug your app on a physical Android device or emulator, just like it can be used on any web application, you can easily debug which file is missing.
