bug: no feedback if android keychain is empty

Start by locating the Android certificate application flow and how it handles the empty keychain result; the issue does not name files or tests. Reproduce on Android with an empty keychain, tap “Apply certificate,” and trace the result reported in the logcat excerpt. Done means the user receives visible feedback when there are no keys to choose from.

Describe the Bug

If the android keychain is empty, the "apply certificate" button does nothing, and gives no feedback what's wrong.

Steps to Reproduce

1. enter a valid URL
2. Click on "Apply certificate"

Expected Behavior

Some kind of popup or toast

Actual Behavior

No response
