Link:WebView – URL mechanism is broken – passing parameters does not work
It’s happen on android 3.0 and higher,on OS2.x is no probrem.
we made webview android apps(its not phonegap),but its cannot work on 3.0,at first I think its not so big problem becouse almost people dont use android OS 3.x. usualy,nobody bought tablet.
but..Several months after, its become big problem.its not work on OS4.0 too.
I must think the way to clear it.
this problem looks webview manage url parameter as url string.too foolish.
so I try to check loading url,I got on WebViewClient’s onPageStarted.
I redirect to url(parameter deleted),Its work.but cannot load parameter,ofcouse I dont pass it.
the next , I pass the parameters by JavascriptInterface.Its call from javascript.
At the last , manage the back button.
Its work on OS 3.x and 4.0,checked by optimus pad and galaxy nexus.
要はパラメータをURLとして扱えないんならとりあえず抜いてHTML読み込んで、あとでJSでもらいにいけばいいんちゃうって作戦。
