Wallpaper activity in android

HI,
I am making a wallpaper activity in my android app. The activity will display all the Wallpapers in a grid.
One way i can think of doing is save all the wallpapers in my drawable directory. Now that is somewhat problem as the drawable directory does not allow to create a subfolder inside it. As there will be several other images inside it will be difficult to differentiate wallpaper from images.

Other way i can think of is getting the wallpaers by making a server call.

Please suggest which way is better and which one to use.

Thanks

Hi Robinsuri,

The solution of your problem is inside your question only.

For first way drawable directory not allow to create sub directory(folder) then you may create a folder in "res". Parent of  drawable directory. There you will allow to create sub directory(folder).


First way:
pro:
- No need server
con:
- Big Apk Size (because all wallpaper images go inside the apk bundle)
- When you need more wallpaper you need to release one more version. For future you may add more wallpaper it will require you a version update

Second way:
pro:
- Easy to add/delete wallpaper on server, no need to manage the app versions. For future you may add/delete image on server app will automatically handle new images with web service call.
- Small apk size
con:
- Need server (Means extra cost, affects your budget)
- Require internet based app. No network on device will affect the app.

See, this thing is totally depend on you. I will suggest you to use server (second way) to manage wallpaper for apps. It will reduce the time, efforts but it will affects your pocket. Final call is yours, you may go with first way also.

Thanks & Regards,

hi thanks for explanation i got the point.
i want to discuss both cases
like if i bring the wallpapers thru network call. where will the wallpapers get stored ?
also do i need to make network call each time to load the wallpapers ? or make it once and use the saved ones.

also wallpapers need to be of all sizes ie. hdpi, mdpi, xhdpi, xxhdpi. i think thats not gonna be an issue just confirming

Hi,

I think you need to implement app in a way that every particular time duration it will call the webservice and update the wallpaper inside the app. So, no need to call every time, it will reduce the webservice call and reduce the server traffic. The app will call and update it on every time launch or call after some specific time.

Refer this link for storage option in android. Using the External Storage you will achieve this.

no issue with the image sizes but may be chance of exception with big size image arise, you may avoid it by proper exception handling.
