It will be tempting to write a trust manager to trust all certificate. But beware, you will be rejected in playstore review. The following code will give you safe way to trust your CA (Certificate Authority).
Place your certificate in app/src/main/res/raw folder (raw folder may not exist, so create one). If you have doubt on which certificate to place, open your url in chrome, and take the intermediate one, usually called Intermediate certificate authority. (one above your domain)
Create a new xml file called -> network_securtiy_config.xml file in app/src/main/res/xml. Paste the following content
<network-security-config>
<base-config>
<trust-anchors>
<!-- Trust preinstalled CAs -->
<certificates src="system" />
<!-- Place your trust certificates here -->
<certificates src="@raw/my_ca" />
</trust-anchors>
</base-config>
</network-security-config>
Thats it. Revalidate your android studio cache and try again. It should work!
