No internet access in signed APK

问题:

I was working on an app that was working fine in the Debug build version and then I created a signed APK using keystore , and then with Android Studio --> Generate SIgned APK.

When I install the signed APK manually by downloading on to my phone, it asks for all permissions including internet access. However post installation, app starts but none of the server calls / API calls are working. The phone has internet connection though (webpages open up in browser)

My android manifest is :

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

回答1:

In my case I found this error on LogCat

Failed to validate the certificate chain, error: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.

So I checked the server certificates in this web to see what happens: https://www.ssllabs.com/ssltest

So should be a server problem
