1,928,861 | 1,928,862 | Launching activity from another application not displaying the activity, but it is running | <p>I've done a lot of searching for the last day and haven't found anything that seems to match the problem I'm having.</p>
<p>(For reasons I won't go into) the app is divided into two separate apks. Each have activities. Only the "core" apk has a MAIN activity that is launched from the Android Launcher. The "plugin" apk has activities that only exist to be called from the first apk's activities and does not have a Launcher icon.</p>
<p>The issue I'm having is that when I create an intent to launch an activity from the "plugin" apk, it does the "launching new activity" sliding animation but immediately bounces back. But it is actually launching the activity because I'm seeing log statements in logcat coming from the new activity. I'm not getting any exceptions and it seems to be working other than the fact I'm not seeing the activity on the screen.</p>
<p>I've tried creating the intent in both of the following ways:</p>
<pre><code>Intent myIntent = new Intent(Intent.ACTION_VIEW);
myIntent.setClassName("com.test.plugin", "com.test.plugin.PluginActivity");
startActivity(myIntent);
</code></pre>
<p>and </p>
<pre><code>Intent myIntent = new Intent();
myIntent.setComponent(new ComponentName("com.test.plugin", "com.test.plugin.PluginActivity"));
startActivity(myIntent);

<p>But both result in the same thing happening as described above.</p>

<p>Essentially, it's a C# version of PHP's Eval() function, so I can render code examples that I've collected over the years and see the end result as well as the actual source code. I'm sure that this has already been asked, but I couldn't find what I was looking for when I looked through the existing questions on here. </p>
<p>This will be a password protected page on my site for my eyes only (theoretically, at least), so I'm not overly concerned about someone running malicious code. But I appreciate the kind warnings that some may feel obliged to offer before answering my question. Seriously, I do.</p>
<p>I have a feeling that about 10 people will see this question and go, "well, obviously it's (Insert Function Name Here), you silly wabbit." So this is my way of admitting my shame of not knowing right here, up front. Especially when I just saw it like a <strong><em>week</em></strong> ago. </p>

<p>This is something that should be standard, if there's to be any chance of interoperability between libraries concurrency-wise. Both for documentation purposes, and also to feed static / dynamic test tools.</p>
<p>If MS isn't doing anything in that direction, it could be done on CodePlex - but I couldn't find anything there, either.</p>

<p>Technically singleton and typical constructor are pretty much different stories in c++ programming since singleton puts constructor as private while typical way is opposite.In my recent internship experiences I have noticed that most coders implement APIs in this manner.</p>
<p>I just wonder if that is the case or unnecessary when both class construction approaches exist in parallel.</p>
<p><em><strong>UPDATE</em></strong></p>
<p>Is constructor & singleton existing in one program practically nonsense cuz singleton stuff in this scope would become useless codes like unhazardous trash?</p>
<p><em><strong>SUMMARY</em></strong>
This is quite a nonsense question...
and what's more,thanks to all of you brilliants
constructor and singleton design pattern are "mutually exclusive" and in terms of vulnerbility,it is the same story as global variables kill our debug time...</p>

394,848 | 394,849 | Service runs then dies | <p>I'm running Win 7 Pro 64-bit. I wrote a service in C# using the .NET 4 framework. It installs properly and starts to run. I know that it runs because it writes some output to a log file. However, after a few seconds it dies. When I use Visual Studio 2010 Pro to run this same code not as a service it never dies. So, my obvious question is regarding the appropriate approach for debugging this since I can't figure out why it should die as a service but not die as a non-service. I've put writes to the log file in several places in the code but it seems to die in a different place every time. The application has 3 threads. Any suggestions are welcomed.</p>
