I'm developing a File Manager app. I want show to the user the internal storage and the sdcard storage if it exists. For internal storage I use Environment.getExternalStorageDirectory().getPath() . How can I get the SD storage? not sure this solution fits a File Manager but after many years trying to get the right code, this is my most recent one: /** * Returns all available SD-Cards in the system (include emulated) * * Warning: Hack! Based on Android source code of version 4.3 (API 18) * Because there is no standard way to get it. * * @return paths to all available SD-Cards in the system

I'm a beginner so please bear with me. Recently, I started reading storage classes in C and I stumbled upon this question: ‪ #‎include‬<stdio.h> int fun() { static int num = 16; return num--; } int main() { for(fun(); fun(); fun()) printf("%d \n", fun()); return 0; } This program outputs : 14 11 8 5 2. 1) Can any please tell me how does this code work? 2) When I keep --num in fun() ,it is running an infinite loop. Why it happens like that? static int num = 16; means that num will be initialized as 16 and it will not be destroyed when the function returns. return num--; means that num value

What is the best document storage strategy in NoSQL databases?

谁说胖子不能爱 提交于 2019-12-01 01:17:26
NoSQL databases like Couchbase do hold a lot of documents in memory, hence their enormous speed but it's also putting a greater demand on the memory size of the server(s) it's running on. I'm looking for the best strategy between several contrary strategies of storing documents in a NoSQL database. These are: Optimise for speed Putting the whole information into one (big) document has the advantage that with a single GET the information can be retrieved from memory or from disk (if it was purged from memory before). With the schema-less NoSQL databases this almost wished. But eventually the

I have a UIViewController for user to input their data and submit to our ASP.NET Webapi. there are about 40 textField and other controls.

This involves making your model class conform to the NSCoding protocol. Use sqlite and a local database. The C api

Caching a large number of images in a jQuery/HTML5 application

问题 I am building a web application in jQuery/HTML5 which will run in Webkit-based browsers on touchscreen kiosks. There are a large (thousands) number of images which the application uses, which I need cached to each browser. At first I thought a HTML5 cache manifest would be the best option (with the thousands of image URLs listed), but now I wonder if there is a better way? I would consider extensions/plugins too... Thanks in advance! 回答1: I like this plugin: http://alexrabarts.github.com

chrome.storage is undefined in chrome extension

若如初见. 提交于 2019-11-30 19:52:00
I'm developing a Google Chrome extension, and have been working on one for a while. So it's been installed for a while, and I updated the manifest file to include the "storage" permission and reloaded the extension. However, when I try it in the console, chrome.storage is undefined . I restarted Chrome and still nothing. My manifest file looks like this: { ... snip ... "permissions": [ "tabs", "http://*/*", "https://*/*", "chrome://favicon/", "storage" ] } I could reinstall the application, but I'm hesitant, since: Will it be the same for the existing users of the extension?

how to access getFilesDir() as an environment variable?

穿精又带淫゛_ 提交于 2019-11-30 17:23:56
I want to access getFilesDir() which is a context method. Is there any way to access it similarly to the way I access external-storage? Environment.getExternalStorageDirectory(); meaning as an environment variable? Maybe application static context? as I want to call this from a non-context class (same app service, but not an activity). laalto It's not possible. Context.getFilesDir() returns a path that is bound to your package and the Context is required to access the package name. Environment is different as there's only constants that are common to all apps running on the same runtime.
