On application startup, you can access the Android intent information via the launch arguments provided to the “main.lua”.
If the Android intent resumes your app (ie: the Corona activity is already running), then you can access the Android intent information via an “applicationOpen” event listener in Lua.
If you copy the following code to your “main.lua” file, it’ll print all information in your launch arguments and applicationOpen event to the Android log. This should give you an idea of how Android intent information is passed to Lua.
local function printTable(table, stringPrefix) if not stringPrefix then stringPrefix = "### " end if type(table) == "table" then for key, value in pairs(table) do if type(value) == "table" then print(stringPrefix .. tostring(key)) print(stringPrefix .. "{") printTable(value, stringPrefix .. " ") print(stringPrefix .. "}") else print(stringPrefix .. tostring(key) .. ": " .. tostring(value)) end end end end local launchArgs = ... print("### --- Launch Arguments ---") printTable(launchArgs) local function onSystemEvent(event) print("\*\*\* system event type = " .. event.type) if (event.type == "applicationOpen") then print("### --- Application Open ---") printTable(event) end end Runtime:addEventListener("system", onSystemEvent)
So, both the launch arguments and the applicationOpen event will have an “androidIntent” Lua table which is only made available on Android. The androidIntent table will have the following fields…
-- Provides the URI returned by the Java Intent.getData() method. androidIntent.url -- Provides the action string returned by the Intent.getAction() method. androidIntent.action -- A Lua string array matching the collection returned by the Intent.getCategories() method. androidIntent.categories -- A Lua table matching the Bundle returned by the Intent.getExtras() method. -- The keys are strings and the values are Lua types that best match the Java value types. -- Note that this does support nested tables/bundles. androidIntent.extras
Also, make sure to do if checks on each of the fields in the “androidIntent” table before attempting to access its data. If the Java equivalent Intent methods return null, then they will be set to nil on the Lua side.
I hope this helps!
