I viewed the code of latest ResolverActivity and noticed that in ResolveListAdapter.bindView method it is using new

Below is what I have so far: Notes: Not all KitKat devices support HCE. To detect HCE support, use this code snippet: boolean isHceSupported = getPackageManager().hasSystemFeature("android.hardware.nfc.hce"); Some people reported that KitKat HCE phones has "Tap & Pay" in NFC Setting.

问题 I've created a webview app which hosts a website within the app in the assets-directory. I want to update the website via an USBstick inserted in my tablets usbslot. I tried it first with the .MEDIA_MOUNTED broadcast which doesn't work for my android 4.4. Tablet. I've searched for an alternative and found the "MediaScannerConnection".
