You can try the specific mime:

    text/plain
or, the more general text mime:

    text/*

[simple and complete example code (less than 50 lines)][1] for app that android will present to the user along with menu list of compatible apps (polaris, browser, etc) when opening a TXT file.

disclaimer: in case user hasnt previously determined a default app  

note; TXT may be changed, you can customize your extensions, if you generate the files that your app consumes.

On chrome, the &quot;search&quot; event is fired on search inputs when user clicks the clear button.

Is there a way to capture the same event in javascript on Internet Explorer 10?

My understanding so far is on our controller request mapping method we can specify *RedirectAttributes* parameter and populate it with attributes for when the request gets redirected.

*Example*:

    @RequestMapping(value=&quot;/hello&quot;, method=GET)
    public String hello(RedirectAttributes redirAttr)
    {
       // should I use redirAttr.addAttribute() or redirAttr.addFlashAttribute() here ?
       
       // ...

       return &quot;redirect:/somewhere&quot;;
    }

The redirect attributes will then be available on the target page where it redirects to.

However *RedirectAttributes* class has two methods:

 - [`addAttribute()`][1]
 - [`addFlashAttribute()`][2]

Have been reading Spring documentation for a while but I&#39;m a bit lost. What is the fundamental *difference* between those two, and how should I choose which one to use?

I&#180;m trying to share a `.txt` file with share intent. If I set &quot;text/plain&quot; as mime type, it reads the content like text not like text file, then the options given in the share menu are Whatsapp, Line, etc..

Does anybody know how to configure the share intent so that the share options are only the programs that are able to send a `.txt` file (Gmail, Dropbox, etc.. but not Whatsapp..)? Thanks

I am trying to get the driving direction between the two positions:

    LatLng(12.917745600000000000,77.623788300000000000)
    LatLng(12.842056800000000000,7.663096499999940000)

The code which i have tried:
   

    Polyline line = mMap.addPolyline(new PolylineOptions().
        add(new LatLng(12.917745600000000000,77.623788300000000000),
        new LatLng(12.842056800000000000,7.663096499999940000))
           .width(5).color(Color.RED));

But this draws a straight line between the two points .&lt;br/&gt;&lt;br/&gt;
Is there any other method/way to get the driving directions between these two points.

What is the default layout background

I am developing an Android App. In which everything is working right. My app is ready to launch. But there I need to implement one more feature. I need to display a popup that contains

   `Rate It` and `Remind me later`

Here if any user rates the app in the market then the popup won&#39;t be disappeared.
I have searched in Google and found one [link][1]. With this, I understand that it&#39;s not possible to know. So I need a suggestion for this. 

Has anybody faced this situation before? If so, is there any solution or any alternative for this?

Is it possible, and if so, how I can achieve this?

How do I read a text file of about 2 GB?

I have multiple text file with about 100,000 lines and I want to split them into smaller text files of 5000 lines each. 


I used:

    split -l 5000 filename.txt

That creates files:

    xaa
    xab
    aac
    xad
    xbe
    aaf


files with no extensions. I just want to call them something like:

    file01.txt
    file02.txt
    file03.txt
    file04.txt


or if that is not possible, i just want them to have the &quot;.txt&quot; extension. 

Split text file into smaller multiple text file using command line

I already have read https://stackoverflow.com/questions/24097826/read-and-write-data-from-text-file     

I need to append the data (a string) to the end of my text file.    
One obvious way to do it is to read the file from disk and append the string to the end of it and write it back, but it is not efficient, especially if you are dealing with large files and doing in often.     

So the question is &quot;How to append string to the end of a text file, without reading the file and writing the whole thing back&quot;? 

so far I have:     

        let dir:NSURL = NSFileManager.defaultManager().URLsForDirectory(NSSearchPathDirectory.CachesDirectory, inDomains: NSSearchPathDomainMask.UserDomainMask).last as NSURL
        let fileurl =  dir.URLByAppendingPathComponent(&quot;log.txt&quot;)
        var err:NSError?
        // until we find a way to append stuff to files
        if let current_content_of_file = NSString(contentsOfURL: fileurl, encoding: NSUTF8StringEncoding, error: &amp;err) {
            &quot;\(current_content_of_file)\n\(NSDate()) -&gt; \(object)&quot;.writeToURL(fileurl, atomically: true, encoding: NSUTF8StringEncoding, error: &amp;err)
        }else {
            &quot;\(NSDate()) -&gt; \(object)&quot;.writeToURL(fileurl, atomically: true, encoding: NSUTF8StringEncoding, error: &amp;err)
        }

Is there an existing possibility to trigger the share functionality in local browsers on smartphones via HTML or JavaScript?

Of course there are many services which provide a share button. But when I e.g. want to share a website on facebook, I need to be logged in to facebook in the browser I am currently using.

Almost all browsers got an own share functionality build in, which triggers a system menu to choose which app you want to use to share:

![System share menu in android os][1]

This question is about: How to trigger this menu?

I know it is possible to trigger a phone call with a specified prefix in href attribute of links, like `tel:` or `callto:`. Maybe such a shortcut for this share menu is also existing? Or some javascript code? Or a totally different way how to do it?

Thanks in advance.

Default Sharing in iOS 7

I have this method so far , but it came up like something is missing

for example I have a file /sdcard/sound.3ga that returns false ( like there is no activity that can handle this type of file ) , But when I open it from the file manager it opens with the media player with no problem

I think this intent is not complete and I need to to something more to make my self sure that the handlerExists variable will be false ONLY if there is no activity that can handle this intent

    PackageManager pm = getPackageManager();
    Intent intent = new Intent(android.content.Intent.ACTION_VIEW);
    String extension = android.webkit.MimeTypeMap.getFileExtensionFromUrl(Uri.fromFile(new File(uriString)).toString());
    String mimetype = android.webkit.MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension);
    intent.setDataAndType(Uri.fromFile(new File(uriString)),mimetype);
    boolean handlerExists = intent.resolveActivity(pm) != null;

How to check if an intent can be handled from some activity?

I have been getting the &quot;ERROR 404.3 Not Found&quot; for JSON file that I am calling using AJAX call on &quot;Internet Information Services 7.5&quot; even after I have activated all the &quot;Application Development Features&quot;. Other than JSON file, all other files are getting loaded.

I am running an HTML page on IIS server on my local machine.

If I open the file directly then there is no problem at all. When I host the files on an online server it works fine.

Any quick help will be much appreciated.

ERROR 404.3 Not Found for JSON file

I have read [this][1] and [this][2] questions which seems to suggest that the file MIME type could be checked using javascript on client side. Now, I understand that the real validation still has to be done on server side. I want to perform a client side checking to avoid unnecessary wastage of server resource.

To test whether this can be done on client side, I changed the extension of a `JPEG` test file to `.png` and choose the file for upload. Before sending the file, I query the file object using a javascript console:

    document.getElementsByTagName(&#39;input&#39;)[0].files[0];

This is what I get on Chrome 28.0:

&gt; File {webkitRelativePath: &quot;&quot;, lastModifiedDate: Tue Oct 16 2012
&gt; 10:00:00 GMT+0000 (UTC), name: &quot;test.png&quot;, type: &quot;image/png&quot;, size:
&gt; 500055…}

It shows type to be `image/png` which seems to indicate that the checking is done based on file extension instead of MIME type. I tried Firefox 22.0 and it gives me the same result. But according to [the W3C spec][3], [MIME Sniffing][4] should be implemented.

Am I right to say that there is no way to check the MIME type with javascript at the moment? Or am I missing something?

How to check file MIME type with javascript before upload?

I am curious about the semantics of the MIME types `application/javascript` versus `text/javascript`.  

Obviously, one is supposed to be executed, and the other is supposed to be just text. 

I see `application/javascript` when looking at headers of an external .js load.

    HTTP/1.1 200 OK
    Date: Mon, 13 Jan 2014 18:32:58 GMT
    Server: Apache/2.2.22 (Unix) mod_ssl/2.2.22 OpenSSL/0.9.8e-fips-rhel5
    Content-Type: application/javascript
    Content-Length: 856
    keep-alive: timeout=5, max=59
    Via: 1.1 (jetty)
    Accept-Ranges: bytes

If this `application/javascript` will execute the javascript, why don&#39;t we use

    &lt;script type=&quot;application/javascript&quot;&gt;
      // some js code.
    &lt;/script&gt;

And vice-versa, why is an external js load not `text/javascript`?

text/javascript vs application/javascript

After several searches online, I couldn&#39;t find a place that could tell me every existent mime type for different types of media in android applications.

Here are the ones I know that exist and work:

For **Text**

    &quot;text/plain&quot;

For **Image**

    &quot;image/jpeg&quot;
    &quot;image/bmp&quot;
    &quot;image/gif&quot;
    &quot;image/jpg&quot;
    &quot;image/png&quot;

For **Video**

    &quot;video/wav&quot;
    &quot;video/mp4&quot;

These are the ones I have and know that work, I am lacking several for video and sound type files. Does anyone know a place where every android mime-type is described or do you guys ever used another mime-type for these different types of media?

EDIT:

I am using this in an application that monitors SMS and MMS and in the MMS type manages the content inside it. The code I have runs for every version above 8.
