storage

问题 I am calculating the free internal storage space using the code below: StatFs statInt = new StatFs(intPath); bytesAvailableInt = (long) statInt.getAvailableBlocksLong() * (long) statInt.getBlockSizeLong(); where intPath is the path to the internal storage. The above code works fine except the case where on Android M, the SD card is formatted as internal storage - in this case, the above code returns the real internal storage free space, not the real + sd card free space combined. Is there

问题 I am building a mobile app that must work in Blackberry, iPhone and Android phones. I am building this mobile app in HTML5, CSS and JQuery Mobile. Then I will use PhoneGap to allow the code to run as a native mobile app for the phone. The mobile app must be able to work without connection to the internet. The only time the app must require an internet connection is when it loads for the first time, because that's when the app will download over 50 MB worth of data. Next time the app has

问题 I need a help with creating virtual directory pointing to local storage in Windows Azure (production environment). I can set up a virtual directory manually but it is being erased every time Azure is restarted.

问题 I have the following query: var nodes = DB.Nodes .Where(x => x.Lon > 486400 && x.Lon < 486600 && x.Lat > 5025100 && x.Lat < 5025300) .Join(DB.RoadNodes, x => x.Id, y => y.NodeId, (x, y) => x); This searches all the nodes in DB.Nodes near a certain location, then it checks whether the node is a road junction by taking a join with DB.RoadNodes ; however, this takes several seconds which is slow. It looks like I have to do two things here: Optimize the Where part which takes ~5 seconds on its

问题 I'm not sure if I should use HTML5 storage for this or not. My question is about how I can accomplish the following: Think of a wall in a museum with an empty frame. I want the user to upload an image from his or her computer. This image will than be shown in the frame on the wall (a div). If the user wants to check another image, the previous image can be 'removed' and the next should show up. In the fiddle below is an example of html5 storage, but it stores multiple images. I just want one

问题 Well, I have a new project, and I've not done anything like it before, but so far so good. I am in need of having to pass some data from one page to another, and there is no limit to the amount of data that gets passed. At first, I was thinking of POST-ing it, and then when each page loads, just grab the POST data, and store it in an array, but to me that sounds a bit too over complicated or something for what I want to do. Then I thought about HTML5 and localStorage, but since there is a

问题 My app loads different types of files from my server to the device storage. For all my files i want to open, i have the path of the files in the storage. For .pdf -Files I am using a WebView which opens the .pdf -Files at the given path (for example) Therefore I split the path var fileType = path.Split('.').Last().ToLower(); and if the fileType is pdf , I open the WebView.
