I have two apps in the google play store. Is it possible to create an http link from one to another in the description of the first?
Google Play descriptions do not support links. You can tell the reader the name of the app, nothing more.
Plus, in any case, your app will come under the "Related Apps" and "More from developer" headings in most cases.
If you put full url address in app description (with https protocol, not only www) it will be visible as a link in browser.
eg: https://play.google.com/store/apps/details?id=domain.company.appname
Of course google play links to apps aren't nice so you can use some url converters.
Google has documentated how to properly link within google play to other resources like a store listing, developer page, a search result etc..
Linking to a store listing
Use the format below to deep-link directly to an app's Store listing page, where users can see the app description, screenshots, reviews and more, and then install it.
To create the link, you need to know the app's fully qualified package name, which is declared in the app's manifest file. The package name is also visible in the Google Play Console.
http://play.google.com/store/apps/details?id=<package_name>
Here's an example:
http://play.google.com/store/apps/details?id=com.google.android.apps.maps
A URL of the following form will be converted to a clickable link and will redirect to the address specified in YOUR_URL.
https://www.google.com/url?q=YOUR_URL
eg: https://www.google.com/url?q=https://play.google.com/store/apps/details?id=domain.company.appname
Google Play descriptions do not support links.
That not true.
You can add links to other application in google play with <a>
tag.
For example, link to my app:
<a href="https://play.google.com/store/apps/details?id=org.ros.android.android_all_sensors_driver">ROS Sensors</a>
You can look at my description app how i do it:
ROS Sensors
We can provide links in play store description using two methods.
<a href="https://www.google.com">Visit Link</a> https://www.google.com
Output in play store app:
Visit Link https://www.google.com
Output in play store website:
Visit Link https://www.google.com
Note :
The below code will not make any link in play store app
Visit Link <a href="https://www.google.com">https://www.google.com</a>
