Greg Pomerantz 349445219b Android: reliable build script; GUI: fix list not drawn until first tap.

scripts/build.sh (documented in README) builds, manifest-patches
( MANAGE_EXTERNAL_STORAGE ), signs and installs the APK in one go.
Without the permission the system 'All files access' toggle is grayed
out on Android 11+.

GUI fix: the event loop only checks the 'updated' channel when it is
not blocked in w.Event(), and gioui only emits frames on invalidation
or user input, so the initial list load was never drawn until a tap.
The updater now signals non-blocking and invalidates the window itself;
the animation ticker gets the same wake-up treatment.

passgo

This repository includes Go code to interact with pass, the Unix password manager. Library code is provided to open a password store, list saved passwords, and decrypt specified passwords. The library provides a simple passphrase input function, or, if gpg-agent is running (on MacOS), it will connect automatically to request your GPG passphrase. On Android, passgo connects to OpenKeychain. MacOS and Android users can also ask passgo to copy a password directly to the clipboard.

store := passgo.Store{}
// directory defaults to ~/.password-store, or set it manually here:
// store.Dir = "/home/me/.pw-store"
err := passgo.GetStore(&store)
if err != nil { ... }
passlist := store.List()
for _,x := range passlist {
	if x.Pathname == "myPass" {
		p, err := store.Decrypt(x.Pathname)
		if err == nil {
			passgo.Clip(p) // put on the clipboard
		} else {
			log.Fatal("Cannot decrypt ", x.Pathname)
		}
	}
}
/// or just do:
p, err := store.Decrypt("myPass")
...

Also included is a simple GUI front-end using Gio that works on MacOS and Android. See cmd/passgo-gui.

Building the Android APK

Use scripts/build.sh — do not build by hand:

./scripts/build.sh phone          # build + install on the phone
./scripts/build.sh phone --no-install
./scripts/build.sh emu            # emulator build (amd64)

It outputs cmd/passgo-gui/passgo-gui.apk (APKs are git-ignored and regenerated by the script). The script, in order:

gogio -target android -targetsdk 34 (from ~/go/bin; packages the Go code plus the *.jar JNI classes found in cmd/passgo-gui/),
apktool decode → inject MANAGE_EXTERNAL_STORAGE into the manifest (gogio's hardcoded permission table lacks it, and without it the system "All files access" toggle is grayed out on Android 11+) → apktool rebuild,
sign with the debug keystore (~/.android/debug.keystore),
adb install -r.

Prereqs: JDK, Go + gogio, Android SDK at ~/android-sdk (platform-tools + build-tools 35.0.0). apktool v3.0.3 is auto-downloaded to ~/android-sdk/tools/apktool.jar if missing. The script checks each prereq and says what is missing. The phone is reached via adb over the WireGuard address (see the global AGENTS.md).
