5,499,327 | 5,499,328 | Automatically install/uninstall an application from within another application | <p>I am developing an Android device management service. </p>
<p>One of the functions for this is specifying what apps should be installed on registered devices of the service.</p>
<p>The scenario is that a manager will upload an enterprise app to the service for use on his employees' Android devices.</p>
<p>He then asks the service to deploy the app. The service communicates with a pre-installed app on the devices. This app downloads the enterprise app then installs it without any confirmation from the user. </p>
<p>Another requirement of this is that the user is prevented from installing or un-installing applications themselves.</p>
<p>I have been looking at the android.app.admin package but the policy functionality seems limited. I have also discovered that it is possible to donwnload an APK then fire an intent to install it. However this needs confirmation from the user.</p>
<p>In short, is it possible to install an Android application from within another application without any confirmation from the user whatsoever?</p>

<p><code>IList<Facility> Facilities = new List<Facility>();</code></p>
<p>The above line is at the core of the problem... the other oddities all throughout the code come from being unable to use interfaces for some things and therefore the data has to be copied back out into a List before using them (for example exporting via webservice, does not allow using an interface, must be an implementation of IList)</p>
<p>Now I understand interfaces are wonderful in the sense that you can write methods which expect the methods presribed in the interface to exist on the implementation which is being passed to your method but...</p>
<p>Can someone please help me out here... can anyone think of a reason you'd immediately downcast a List back to its interface in the data layer of an application?</p>
<p>Also just to make it clear... these lists are not used for interchangeable data types either, this occurs at the point where the List is defined and stored, and there is an IList per datatype which is stored.</p>

All of the implementation classes usually contain lots of <code>final static</code> variables and static initialization code which I would like to fire only once in its lifetime.</p>
<p>But since I am using the newInstance() call, I am under the impression that the old object gets GCed and the class is initialized again and hence all the static variables.</p>

...
}
...
}
</code></pre>
<p>Somehow I have the feeling that I shouldn't be using the Object class. However my reason for doing so is that not all cars have the same setter functions, now I could split this into multiple setters with the same name, but with different types of <code>valueToSet</code>, that however requires a lot more code, especially if my <code>valueToSet</code>'s have largely different types.</p>

1,827,666 | 1,827,667 | How to append before last li in dropdown list | <p>I am using the following form builder (<a href="http://dontlink.me/formbuilder/" rel="nofollow">http://dontlink.me/formbuilder/</a>) and making lots of changes to it to work the way I want.</p>
<p>One of the things I want it to do is when you add a new form field, I want that form field to be placed at the bottom of the list... At the moment they are placed at the top.</p>
<p>This is the code that adds the new li to the list... I've simplified it down to the part that actually does the adding...</p>
<pre><code>var result = '<li>The new form field code goes here....</li>';
var into = $("#form_builder_panel ol");
$(into).prepend(result);
</code></pre>
<p>For some reason by default they add an "li" tag into the code and give it a class of 'last-child'.</p>
<pre><code><div id="form_builder_panel">
<form method="post" action="preview.php" class="fancy">
<fieldset class='sml'>
<legend>Built Form</legend>
<ol>
<li class="last-child"></li>
</ol>
</fieldset>
</code></pre>
<p>Now I tried changing that third line of code to the following:</p>
<pre><code>$(into).append(result);
</code></pre>
<p>But that then puts the 'last-child' li at the top and the script stops working...</p>
<p>So my question is, how do I make it so that it appends a new li to the list but adds it above the 'last-child' li?</p>
<p>Hopefully I am making sense :)</p>

1,341,727 | 1,341,728 | Integer storage - Hexadecimal/Octal | <p>I understand that integers are stored in binary notation, but I was wondering how this affects the reading of them - for example:</p>
<p>Assuming </p>
<pre><code>cin.unsetf(ios::dec); cin.unsetf(ios::hex); and cin.unsetf(ios::oct);
</code></pre>
<p>the user inputs</p>
<pre><code>0x43 0123 65
</code></pre>
<p>which are stored as integers. Now assume that the program wants to recognize these values as hex, oct, or dec and does something like this.</p>
<pre><code>void number_sys(int num, string& s)
{
string number;
stringstream out;
out << num;
number = out.str();
if(number[0] == '0' && (number[1] != 'x' && number[1] != 'X')) s = "octal";
else if(number[0] == '0' && (number[1] == 'x' || number[1] == 'X')) s = "hexadecimal";
else s = "decimal";
}
</code></pre>
<p>the function will read all of the integers as decimal. I put in some test code after the string conversion to output the string, and the string is the number in decimal form. I was wondering if there is a way for integers to keep their base notation.</p>
<p>Of course you could input the numbers as strings and test that way, but then there is the problem of reading the string back as an int. </p>
<p>For example:</p>
<pre><code> string a = 0x43;
int num = atoi(a.c_str());
cout << num; // will output 43
</code></pre>
<p>It seems like keeping/converting base notation can get very tricky. As an added problem, the hex, dec, and oct manipulators wouldn't even help with the issue shown above since the integer is being stored completely incorrectly, it's not even converting to a decimal.</p>
