Preview and Publish a Site from the Android App
The Weebly editor provides a pretty good picture of how your site will look when published, but you can also get an actual preview of both mobile and desktop. Tap on Preview in the upper right, and then choose from Mobile or Desktop by tapping one of the two icons at the top.
If everything looks good, tap Publish to make your site live. If you want to go back and make more changes, tap the back arrow from the Preview screen to return to the editor.
