Hi,
I have a quick question. Is there anyway to find out if a particular app is installed on device? I’m thinking of adding some cross promotion elements to some of my apps but I would like to trigger this only when I know that the user does not have my other app installed on his/her device. If the app is installed the cross-promotion would be very annoying very quickly. Any ideas?
Thanks much for sharing.
Regards,
Kerem
Any ideas? Thanks in advance for your input.
Hi ksan, yes this is feasible on both android and iOS.
Here’s what you need to do:
On the app that you want to promote set your build settings to something like this:
[lua]
settings = {
orientation = {
default = “portrait”,
supported = { “portrait”, “portraitUpsideDown”}
},
iphone = {
plist = {
–UIStatusBarHidden = false,
–UIPrerenderedIcon = true, – set to false for “shine” overlay
CFBundleIconFile = “Icon.png”,
CFBundleIconFiles = {
“Icon.png”,
“Icon@2x.png”,
“Icon-40.png”,
“Icon-40@2x.png”,
“Icon-60.png”,
“Icon-60@2x.png”,
“Icon-72.png”,
“Icon-72@2x.png”,
“Icon-76.png”,
“Icon-76@2x.png”,
“Icon-Small-50.png”,
“Icon-Small-50@2x.png”,
“Icon-Small.png”,
“Icon-Small@2x.png”,
“Icon-Small-40.png”,
“Icon-Small-40@2x.png”
},
UIStatusBarHidden = true,
UIPrerenderedIcon = true, – set to false for “shine” overlay
UIAppFonts =
{
“HelveticaNeue-Light.ttf”,
},
UIApplicationExitsOnSuspend = false, – uncomment to quit app on suspend
CFBundleURLTypes = {
{
CFBundleURLSchemes =
{
–“fb1234567890”, – example scheme for facebook
“bargainhunter”, – bargain hunter url scheme
},
},
},
}
},
plugins =
{
– key is the name passed to Lua’s ‘require()’
[“CoronaProvider.analytics.flurry”] =
{
– required
publisherId = “com.coronalabs”,
},
},
– Android permissions
androidPermissions = {
“android.permission.INTERNET”,
},
android =
{
intentFilters =
{
{
label = “Bargain Hunter”,
actions = { “android.intent.action.VIEW” },
categories =
{
“android.intent.category.DEFAULT”,
“android.intent.category.BROWSABLE”,
},
data = { scheme = “bargainhunter” },
},
– You can add more intent filters here.
},
},
}[/lua]
In the app that you are using to promote your other app you could do something like this:
[lua]
local platform = system.getInfo( “platformName” )
local storestring = system.getInfo( “targetAppStore”)
local appinstalled = false
local function getappfromstore()
local options =
{
iOSAppId = “xxxxxxxxxx”,
nookAppEAN = “xxxxxxxxxxxxxxxx”,
androidAppPackageName = “com.icyspark.bargainhunter”,
supportedAndroidStores = {storestring},
}
native.showPopup(“appStore”, options)
end
if platform == “Android” then
local appIcon = display.newImage(“android.app.icon://com.icyspark.bargainhunter”,160,-200)
if appIcon then
– App is installed.
display.remove(appIcon)
appIcon = nil
appinstalled = true
else
– App is not installed.
appinstalled = false
end
local otherappbutton = display.newRect(sceneGroup,160,240,50,50)
otherappbutton:setFillColor(0.5)
local function clickbanner(self,e)
– button listener for when you press the button to either load other app or get it from store
if e.phase == “began” then
self:setFillColor(0.88)
elseif e.phase == “ended” then
self:setFillColor(0.5)
if platform == “Android” then
if appinstalled == true then
if not system.openURL(“bargainhunter://”) then
getappfromstore()
–print(“App Not Installed”)
end
else
getappfromstore()
end
elseif platform == “iPhone OS” then
if not system.openURL(“bargainhunter://”) then
getappfromstore()
end
end
end
return true
end
otherappbutton.touch = clickbanner
otherappbutton:addEventListener(“touch”)
[/lua]
I hope this helps get you started.
This is amazing!!! Thank you so very much for sharing this extensive code with me and all folks on this forum. I am very grateful. I will use this right away. Most appreciated.!!!
