i really need help for my wikimedia_android app. it is not easy to study the project ,since i don't know where i can get the design documents about the android app . i have study wikimedia_android app for about a month(download from https://github.com/wikimedia/apps-android-wikipedia) ,i also build a mediaWiki (download from https://www.mediawiki.org/wiki/Download) on my wampserver (i didn't install any extentions on mediaWiki,i don't know what Extentions i need to install) . In left menu of app ,there are functions such as : Log in , Today , History ,Saved pages ,Nearby ,Random

What i want to do is that i tried to build my own android app which will connect to my local mediaWiki server (192.167.137.1) to get all the data the app need.And all the functions (Log in , Today , History ,Saved pages ,Nearby ,Random ) work well.

What i have done : i modify the domain = "192.168.137.1", language ="zh" in Site.java because of that my app can register and login ,app communicates well with my local mediaWiki server. and it will show my username in left menu.

Problem i met: after i click "Today" ,the page of Today did not display on my android phone and i got these message :

03-11 15:35:46.201 31202-31202/org.wikipedia.alpha W/AwContents?s nativeOnDraw failed; clearing to background color.

2: Is that because I didn't install any extentions on my local mediaWiki ? I saw "Mobile Web" and "Extension:MobileFrontend" in https://www.mediawiki.org/wiki/Wikimedia_mobile_engineering .If that true ,what Extentions do i need to install and how ?

3: Or maybe i need to write some php program in my local mediaWiki server ? because it is my local server not Wikipedia server which may have some php program achieved by it's team

4: the function "Nearby" and "Random" also didn't work,is that the same reason with "Today" ? if not ,what maybe the reasons ?

I am now really confused with the project ,i have been working on that problem for two days but get nothing, I really hope someone can help .
