If you don't have an android device and wan't to check how your store will look in android you can do so using Chrome's dev tools and this is how you do it
Visit your store in Chrome in your desktop for example https://prodfire.myshopify.com/
Right click on the page and select "Inspect"
On selecting "Inspect" it will open the dev tools in Chrome
There you can select the device icon
On clicking it will allow you to preview as different devices you can choose one of the device from the dropdown
After selecting the device refresh your page
To close this view and get back to your normal Chrome click on the close icon of the dev tools
Note

* PushOwl widgets might not show up if you are already subscribed to the store
