On any activity recreation with saved state (config changes such as night mode), the FragmentManager restores the Permissions fragment reflectively and requires a no-arg constructor; it only had Permissions(View), so the activity failed to start with Fragment$InstantiationException. Also regenerate cmd/pad/Permissions.jar from the .java source in both build scripts: gogio does not compile the app's own .java files - it silently merges any *.jar in the Go package dirs into the dex, so the stale Aug-16 jar shadowed source edits (which is how this bug went unnoticed). This crash is separate from the black-screen hang after relaunch, which is fixed in the gioui fork (app/os_android.go: skip the window handshake ack on re-attach).
