MANAGE_EXTERNAL_STORAGE (needed to read the store at /storage/emulated/0/...) cannot be requested with a runtime permission dialog; the user must toggle it in system settings. Port the mechanism from the pad app: - Permissions.java: a Fragment registered at window attach that launches Settings.ACTION_MANAGE_APP_ALL_FILES_ACCESS_PERMISSION (per-app settings screen) when Environment.isExternalStorageManager() is false on API 30+ (runtime READ_EXTERNAL_STORAGE request on older APIs). The guard means the screen appears only until the user grants it. - The compiled classes ship in PgpConnect.jar's directory jar (Permissions.jar); gogio picks *.jar up from the package dir and dexes them. go:generate now rebuilds it. - jni_android.c/h: registerPermissionsFragment(), mirroring registerFragment() for PgpConnect. - Impl wiring: call it from the AndroidViewEvent handler right after InitPgp. Verified on the x86_64 emulator: with the appop denied the system settings screen opens automatically on launch; after granting it, launch is clean and list + OpenKeychain decryption from /sdcard/Pass work end to end.
