mob_photos

Photo / video library picker for apps built with Mob — extracted from mob core as a plugin.

iOS: PHPickerViewController (iOS 14+). Android: the system Photo Picker (PickMultipleVisualMedia). Both run out of process, so no runtime permission dialog is ever shown and no usage-description string is needed.

Installation

# mix.exs
{:mob_photos, "~> 0.1"}

# mob.exs
config :mob, :plugins, [:mob_photos]

The plugin manifest merges READ_MEDIA_IMAGES / READ_MEDIA_VIDEO / READ_EXTERNAL_STORAGE into the host AndroidManifest at build time — the system picker doesn't need them, but they cover OEM fallback pickers on API <= 32. No iOS plist key.

Usage

socket = MobPhotos.pick(socket, max: 5)

def handle_info({:photos, :picked, items}, socket) do
  # each item: %{path: "/tmp/mob_pick_xxx.jpg", type: :image | :video,
  #              width: 1920, height: 1080}
end

def handle_info({:photos, :cancelled}, socket), do: ...

Limits (platform parity, inherited from core)

• iOS items carry only path + type (no width/height; type is an atom).
• Android items carry all four keys, but type is a string ("image"/"video") and width/height are 0 — the picker doesn't probe dimensions.
• The types: option is currently ignored by both native sides; both pickers show images + videos.
