问题 i'm trying to use the method setMobileDataEnabled of the ConnectivityManager class, using SDK 2.2. According to http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/2.2.1_r1/android/net/ConnectivityManager.java/?v=source this method is declared public but with @hide is not available in the SDK and in Eclipse.

问题 I'm writing an application which is supposed to dump data on the SD card and then another application on a pc which should read the data when the device is connected to the pc (in disc drive mode). On my HTC Legend there is a dialog to choose between: Charge only, HTC Sync, Disk drive.. Is there a possibility to set the mode with which the device is connecting to the pc or at least an intent to ask the user to switch the mode? 回答1: I haven't found a way of setting the mode programmatically,

问题 I have a site which is a white label (Multiple versions of the same site) which I've launched recently. There isn't a great deal of traffic yet - mainly bots but probably 800 users per day. It is hosted on Azure with an Azure database in addition to an admin panel located on a non-azure server. Both sites connect to the same Azure database. There are also some worker roles running to process data - 99% of the time they aren't doing anything, but they check regularly. I have always experienced

问题 I need to get the network from which device was disconnected. Now I use: NetworkInfo ni =intent.getParcelableExtra(ConnectivityManager.EXTRA_NETWORK_INFO); And check: ni.isConnected() if this returns false ni - is the network from which the device was disconnected. But ConnectivityManager.EXTRA_NETWORK_INFO is deprecated in API 14. Google says use getActiveNetworkInfo() to get network information. But getActiveNetworkInfo() always returns network with which the device is connected now (

问题 I was looking over the Reachability sample project on developer.apple.com and found that it was a large project just to verify you had network connectivity. First part of the question is "What is the minimum code required to find out if the device can reach a 3G or wifi network?" And next should this be done inside the appDelegate (on start) or inside the first View Controller that is launched? Thank you in advance 回答1: It's not large, it really does what you want. If it is too big for you,
