1,647,083 | 1,647,084 | registerReceiver issue with in-app billing messages? | <p>I'm implementing in-app billing support in my application. I just realized that even though the application has been stopped, the standard billing broadcast receiver is still receiving billing messages from the market service. So, instead of declaring my receiver inside the manifest file:</p>
<pre><code> <receiver android:name=".receiver.billing.BillingReceiver">
<intent-filter>
<action android:name="com.android.vending.billing.IN_APP_NOTIFY" />
<action android:name="com.android.vending.billing.RESPONSE_CODE" />
<action android:name="com.android.vending.billing.PURCHASE_STATE_CHANGED" />
</intent-filter>
</receiver>
</code></pre>
<p>I decided to go with the Context.registerReceiver method in order to ensure that my application is actually ready to correctly handle billing messages:</p>
<pre><code> _billingReceiver = new BillingReceiver();
final IntentFilter filter = new IntentFilter("com.android.vending.billing.IN_APP_NOTIFY");
filter.addAction("com.android.vending.billing.RESPONSE_CODE");
filter.addAction("com.android.vending.billing.PURCHASE_STATE_CHANGED");
_billingService.registerReceiver(_billingReceiver, filter);
</code></pre>
<p>The problem now is that BillingReceiver.onReceive is not called anymore. Is there an issue of some kind preventing billing messages to be sent to dynamically registered receivers. I looked through Google/Android's doc and found nothing.</p>

2,993,834 | 2,993,835 | Job queuing library/software for Java | <p>The premise is this: For asynchronous job processing I have a homemade framework that:</p>
<ul>

<li>Processing can be embedded in a web application or can run by itself in on different machines for scaling out</li>
<li>Web UI for monitoring the queue and canceling queue items</li>
</ul>
<p>I would like to replace this with some ready made library because I would expect more robustness from those and I don't want to maintain this. I've been researching the issue and figured you could use JMS for something similar. But I would still have to build a simple java API, figure out a runtime where I would put the processing when I want to scale out and build a monitoring UI. I feel like the only thing I would benefit from JMS is that I would not have to do is the database stuff.</p>
<p>Is there something similar to this that is ready made?</p>

<li>X amount of machines process those jobs</li>

1,429,982 | 1,429,983 | Need a good way to store Name value pairs | <p>I often run into a situation where I want to have a set of key/value pairs. Here's a pseudo code idea:</p>
<pre><code>DataSet MyRequestStatus
{
Accepted = "ACC",
Rejected = "REJ"
}
</code></pre>
<p>Usage:</p>
<pre><code>InsertIntoTable(MyRequestStatus.Accepted.ToString())
</code></pre>
<p>I want to be able to use the friendly "MyRequestStatus.Accepted", but I want the ToString() to return the cryptic "ACC", NOT "Accepted". Bonus points, implicit conversion rather than having to call ToString().</p>
<p>I haven't found an obvious way to achieve this with Enums. What do you suggest?</p>

5,844,767 | 5,844,768 | How to implement a product (video or audio) for sale in a PHP based website | <p>I'm a complete noob when it comes to php. I can implement a site and do minimal coding (trying to get better), but for what I want to do, I'm not even really sure of the correct search terms so I can research. What I'm trying to do is to allow users to go to a certain section of my site that requires them to login. And once there, they can select videos that they have to purchase to view. I'm not sure if this is something that's straight forward or not. I don't know what type of service I can use to charge them, and how to make the videos available to them once they have purchased. I really don't have a handle on how to make this happen. If anyone can give me some direction, I certainly would appreciate it. Thanks!</p>

<pre><code>#include <iostream>

</code></pre>
<p><strong>In the code piece above, how is the <code>std::cout</code> statement chained?</strong></p>
<p>I understand that an implementation of <code>cout</code> would return the reference to <code>cout</code> object to allow chaining to happen, so it should be executed as:</p>
<pre><code>(((cout << hex) << a) << endl)
</code></pre>
<p>i.e. equivalent to these, in order</p>
<ol>
<li><code>cout << hex</code></li>
<li><code>cout << a</code></li>
<li><code>cout << endl</code></li>
</ol>
<p>But this cannot be the case because somehow value of <code>a</code> needs to be converted to <code>hex</code> form! </p>

<p>Objects of class B, C, and D all go into an array of type A.</p>
<p>Now when they come out I want to cast them back to the original type to use a specific method / variable etc. <strong>How can I do this without having to go through a set of <em>if</em> statements to try and find out what sort of sub class it is?</strong> It makes my code very inflexible as I have to write a new set of <em>if</em> statements every time I add a new class that extends class A. Is there a way to simply return to the exact name of the class that an object is?</p>

2,692,723 | 2,692,724 | Will two same strings read from the System.in be stored in a common memory location? | <p>Suppose we have program like this:</p>

<p>Now, if user types his username twice, <code>userName</code> and <code>userNameCopy</code> Strings will have the same value. Since strings are immutable, will Java compiler be smart enough to use only one memory object with the two references to it, or is this behavior reserved only for the string literals hard-coded into the program?</p>
<p>If the answer is "No, compiler will create two separate object on the heap". why is that so? Is it because searching for the exact match from the pool is slow? If it is, couldn't string pool be implemented like some sort of hash table, or something similar?</p>
