You need the following permission in the manifest as per documentation:

    &lt;uses-permission android:name=&quot;android.permission.DOWNLOAD_WITHOUT_NOTIFICATION&quot; /&gt;

**Note**  
Most of the manifest permissions will be autocompleted by Android Studio, but this will not be auto-completed.

but also need to add that permission to rn-fetch-blob&#39;s manifest that is not given in it.


 

    &lt;uses-permission android:name=&quot;android.permission.DOWNLOAD_WITHOUT_NOTIFICATION&quot; /&gt;

I need a function that will do something like this:

    $arr = array(); // This is the array where I&#39;m storing data

    $f = new MyRecord(); // I have __constructor in class Field() that sets some default values
    $f-&gt;{&#39;fid&#39;} = 1;
    $f-&gt;{&#39;fvalue-string&#39;} = $_POST[&#39;data&#39;];
    $arr[] = $f;

    $f = new Field();
    $f-&gt;{&#39;fid&#39;} = 2;
    $f-&gt;{&#39;fvalue-int&#39;} = $_POST[&#39;data2&#39;];
    $arr[] = $f;

When I write something like this:

    $f = new Field(1, &#39;fvalue-string&#39;, $_POST[&#39;data-string&#39;], $arr);
    $f = new Field(2, &#39;fvalue-int&#39;, $_POST[&#39;data-integer&#39;], $arr);

    // Description of parameters that I want to use:
    // 1 - always integer, unique (fid property of MyRecord class)
    // &#39;fvalue-int&#39; - name of field/property in MyRecord class where the next parameter will go
    // 3. Data for field specified in the previous parameter
    // 4. Array where the class should go

I don’t know how to make a parametrized constructor in PHP.

Now I use a constructor like this:

    class MyRecord
    {
        function __construct() {
            $default = new stdClass();
            $default-&gt;{&#39;fvalue-string&#39;} = &#39;&#39;;
            $default-&gt;{&#39;fvalue-int&#39;} = 0;
            $default-&gt;{&#39;fvalue-float&#39;} = 0;
            $default-&gt;{&#39;fvalue-image&#39;} = &#39; &#39;;
            $default-&gt;{&#39;fvalue-datetime&#39;} = 0;
            $default-&gt;{&#39;fvalue-boolean&#39;} = false;

            $this = $default;
        }
    }





PHP constructor with a parameter

Does anyone know how to round up a number to its nearest multiple of 5?  I found an algorithm to round it to the nearest multiple of 10 but I can&#39;t find this one.

This does it for ten.
    
    double number = Math.round((len + 5)/ 10.0) * 10.0;

Rounding up a number to nearest multiple of 5

I&#39;m trying to use `DownloadManager` in a `Service` class of mine:

		DownloadManager downloadManager = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
		//imageUri is a valid Uri
		Request downloadRequest= new Request(imageUri); 
		//without this line, it works
		downloadRequest.setNotificationVisibility(DownloadManager.Request.VISIBILITY_HIDDEN);
		//subpath is valid
		downloadRequest.setDestinationInExternalFilesDir(this, null, subPath);
		downloadManager.enqueue(downloadRequest);

Without `setNotificationVisibility`, this code works well. But it displays a notification, that I don&#39;t want, because I use this code for lazy-loading images in a `ListView`.

I understand, this notification can be hidden with

    downloadRequest.setNotificationVisibility(DownloadManager.Request.VISIBILITY_HIDDEN);

But in that case, my application crashes with:

Whats' wrong with <code>setNotificationVisibility</code>? How can I had the notification?

I&#39;ve searched on Google, but couldn&#39;t find any relevant results.

I also checked **the official Android docs** and [**this page**][1] (for all the available resources) was all I could find. The **relevant links** (to the **`res/values/`** directory) I found on this page were:

 - [string resources][2]
 - [style resources][3]
 - [more resources][4]

These pages don&#39;t tell anything about the **`res/values/public.xml`** file.  
Here is an **example** I found for [**this  type of file**][5].

Small snippet
-------------

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
    &lt;resources&gt;
        &lt;public type=&quot;attr&quot; name=&quot;commentTextColor&quot; id=&quot;0xAA010007&quot; /&gt;
        &lt;public type=&quot;drawable&quot; name=&quot;add_icon_bl&quot; id=&quot;0xAA020000&quot; /&gt;
        &lt;public type=&quot;layout&quot; name=&quot;act_date_picker&quot; id=&quot;0xAA030001&quot; /&gt;
        &lt;public type=&quot;anim&quot; name=&quot;activity_slide_from_bottom&quot; id=&quot;0xAA040000&quot; /&gt;
        &lt;public type=&quot;xml&quot; name=&quot;pref_menu&quot; id=&quot;0xAA050000&quot; /&gt;
        &lt;public type=&quot;raw&quot; name=&quot;alert_bell_animation_bl&quot; id=&quot;0xAA060000&quot; /&gt;
        &lt;public type=&quot;array&quot; name=&quot;taskRepeat&quot; id=&quot;0xAA070000&quot; /&gt;
        &lt;public type=&quot;color&quot; name=&quot;theme_main_color_bl&quot; id=&quot;0xAA080000&quot; /&gt;
        &lt;public type=&quot;string&quot; name=&quot;no_internet&quot; id=&quot;0xAA0a0001&quot; /&gt;
        &lt;public type=&quot;id&quot; name=&quot;page1&quot; id=&quot;0xAA0d0015&quot; /&gt;
    &lt;/resources&gt;

As you can see from the **`type`** attribute, it contains pretty much **all the standard resource types** that you normally put in **separate directories** under the **`res`** directory...

What is the use of the res/values/public.xml file on Android?

In my application I am uploading an image from gallery and I want to store this image in the SQLite database. How do I store a bitmap in the database? I am converting bitmap to a string and saving it in the database. While retrieving it from the database, I am not able to assign that string to ImageView since it is a string.


Imageupload12 .java:
```java
     public class Imageupload12 extends Activity {
      Button buttonLoadImage;
      ImageView targetImage;
      int i = 0;

       Bundle b = getIntent().getExtras();
       if (b != null) {
        img = b.getString(&quot;image&quot;);
        targetImage2.setImageURI(&quot;image&quot;);
        //i am getting error as i cant assign string to imageview.

I tried `Location.getAltitude()`, but that is terribly inaccurate.
Any advice?

So I am not experienced in dealing with a plethora of file types, and I haven&#39;t been able to find much info on exactly what `.sh` files are. Here&#39;s what I&#39;m trying to do:

I&#39;m trying to download map data sets which are arranged in tiles that can be downloaded individually: http://daymet.ornl.gov/gridded

In order to download a range of tiles at once, they say to download their script, which eventually leads to `daymet-nc-retrieval.sh`: https://github.com/daymet/scripts/blob/master/Bash/daymet-nc-retrieval.sh

So, what exactly am I supposed to do with this code? The website doesn&#39;t provide further instructions, assuming users know what to do with it. I&#39;m guessing you&#39;re supposed to paste the code in to some other unmentioned application for a browser (using Chrome or Firefox in this case)? It almost looks like something that could be pasted in to Firefox/Greasemonkey, but not quite. Just by a quick Google on the file type I haven&#39;t been able to get heads or tails on it. 

I&#39;m sure there&#39;s a simple explanation on what to do with these files out there, but it seems to be buried in plenty of posts where people are already assuming you know what to do with these files. Anyone willing to just simply say what needs to be done from square one after getting to the page with the code to actually implementing it? Thanks.
