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.

# Build (and optionally install) the passgo-gui Android APK.
|
|
#
|
|
# Usage:
|
|
# ./scripts/build.sh [phone|emu] # build + install (default: phone)
|
|
# ./scripts/build.sh phone --no-install # build only
|
|
#
|
|
# Output: cmd/passgo-gui/passgo-gui.apk
|
|
#
|
|
# Prereqs on this workstation:
|
|
# - JDK (java on PATH)
|
|
# - Go + gogio (~/go/bin)
|
|
# - Android SDK at ~/android-sdk (platform-tools, build-tools 35.0.0)
|
|
# - debug keystore at ~/.android/debug.keystore
|
|
# apktool is not a prerequisite: if it is missing, the script downloads
|
|
# v3.0.3 to the stable location ~/android-sdk/tools/apktool.jar.
|
|
#
|
|
# Why the apktool detour: gogio's manifest permissions come from a hardcoded
|
|
# table (only the legacy READ/WRITE_EXTERNAL_STORAGE). On Android 11+ the
|
|
# "All files access" settings toggle is grayed out unless the app declares
|
|
# MANAGE_EXTERNAL_STORAGE, which Permissions.java opens at startup. So we
|
|
# decode the gogio APK, inject the permission, rebuild, and re-sign with
|
|
# the debug key.
