android-4.4-kitkat

问题 I am having problems with loading javascript functions, which are in external file, into webview in Android Kitkat. My approach for earlier versions was that i implemented my own webview client and in method onPageFinisned i called mWebView.loadUrl("javascript:" + functions); later, when i wanted to call some js method, i call same code, like mWebView.loadUrl("javascript:" + someFunction); In android kitkat there is new method evaluateJavascript, which replaces my code with calling that

I've seen the effect on Samsung Galaxy S5 stock dialer app, so I want to perform this effect.

And is there anything I can do about it? 回答1: I found some people suggest to ignore this error, this is a good option only when your emulator initiating but in my case I ignore this error and my emulator was being start but after that my app didn't appear in that emulator. Then I realized this non-appearance

问题 In my application, I download a file using an HttpURLConnection in an AsyncTask. If the file takes too long to download, then I want cancel it; and I do this by closing the stream and calling disconnect() on the HttpURLConnection object.

When the app starts, in onCreate I inflate the layout and add a SurfaceView to the surfaceViewContainer. On a Samsung S2 with 4.1.2 and a S3 with 4.3 everything works fine, I can see the SurfaceView drawn and I
