2,781,160 | 2,781,161 | What's the point of FILL_AND_STROKE? | <p>Android newb here, so I'm trying out the android graphics classes.
I wanted to draw some arcs/circles with a fill color and black outline.
The Paint class has a style for FILL_AND_STROKE, but there doesn't seem to be a way to set the fill color vs. stroke color. So as far as I can tell it's the same as FILL?</p>
<p>So what's the point of FILL_AND_STROKE if you can't set a separate fill and stroke color?
I haven't managed to find a good explanation.</p>
<p>(I solved my simple problem by doing a fill first, then a stroke, naturally)</p>
<p>Edit:
I ran into this bug report: <a href="http://code.google.com/p/android/issues/detail?id=4086">http://code.google.com/p/android/issues/detail?id=4086</a></p>
<p>Comment 4 and 5 seem to imply that FILL_AND_STROKE is basically the same as FILL and it will be 'fixed' in 2.2. I guess they'll add a new color?</p>

5,162,819 | 5,162,820 | How to handle conditional-imports-dependent exceptions? | <p>I'm wondering what is the most elegant way to handle exceptions that depend on a conditional import.
For example:</p>
<pre><code>import ldap
try:
...
l = ldap.open(...)
l.simple_bind_s(...)
...
except ldap.INVALID_CREDENTIALS, e:
pass
except ldap.SERVER_DOWN, e:
pass
</code></pre>
<p>In the real-world scenario (the one that made me think of this), we have a cherrypy server with a 'login' page. And the login method does a lot of stuff - one of them is authentication.</p>
<p>However, I can use something else than LDAP to do authentication, in which case I do not want to import ldap at all.</p>
<p>But if I make the 'import ldap' statement conditional (e.g. it only gets imported when USE_LDAP value is True in a config file), I have to do something with the 'except's too. The question is: what? </p>
<p>Catch a generic Exception, use an if statement to check whether we use LDAP (i.e., ldap is imported) and then use isinstance to check, whether the Exception is the correct type (ldap.INVALID_CREDENTIALS)?</p>
<p>Try to concentrate the code that depends on ldap at one place and re-raise a user defined exception that finally gets caught in the login method?</p>
<p>What would you suggest as the most pythonic?</p>

For the moment the cli is resided in the same project as the original application but I'm planning to extract it into it's own project, effectively building 2 separate executable jars enabling me to start the cli as needed and query the other running program for information.</p>
<p>I'm trying to figure out the easiest and most lightweight solution to call a remote service, on the same machine.
I looked at spring remoting but many of the provided solutions such as HttpInvoker, Hessian/Burlap, JAX RPC web services are based on HTTP or SOAP and therefore not suited for the job.

5,986,454 | 5,986,455 | Preferred way of declaring and converting primitives to strings | <p>I have 3 options:</p>
<ol>
<li>Declare <code>double member</code> and later when I have to pass <code>String</code> use <code>member + ""</code>.</li>
<li>Declare <code>double member</code> and later when I have to pass <code>String</code> use <code>Double.toString(member)</code>.</li>
<li>Declare <code>Double member = 0.0</code> and later when I have to pass <code>String</code> use <code>member.toString()</code>.</li>
</ol>
<p>My opinions:</p>
<ol>
<li>The shortest one. However, <code>member + ""</code> will be converted to <code>new StringBuilder().append(member).append("").toString()</code>, which seems not elegant.</li>
<li>In <code>Double.toString(member)</code> I don't like that it doesn't start from the word <code>member</code>, which is the most important. We only need to convert it. It's better if <code>member</code> is in the beginning, because I pay most attention to the beginning of word. Quick glance and I know "ah, ok I'm passing member". And with <code>Double.toString(member)</code> my very first concentration goes to "ah, ok... a Double, we are doing toString... of a member! Ah ok".</li>
<li><code>member.toString()</code> looks fine and it can be typed even faster then + "", because of autocompletion in Eclipse. However, objects are much slower then primitives. <a href="http://simononsoftware.com/primitives-and-objects-benchmark-in-java/" rel="nofollow">Reference.</a></li>

<ol>

<li>In the below example, why don't we need class <code>CompositeObjCloneMe</code> as cloneable? Does <code>cObj</code> won't be cloned while trying to clone <code>CloneMe</code> object?
Note: Even making <code>CompositeObjCloneMe</code> as cloneable doesn't have any impact on output.</li>
<li>Why the output is behaving like shallow copying (Not deep coppying) since program is setting primitive value(<code>setCObjValue = 100</code>) of a class? (where primitive fields are deeply copied)</li>
<li><p>Is it immutable Objects && primitives are inherently deeply copied?</p>
<pre><code>class CloneMe implements Cloneable {
private CompositeObjCloneMe cObj;
public CloneMe() {
cObj = new CompositeObjCloneMe();
}
public void setCObjValue(int myOwnDt) {
this.cObj.setObj(myOwnDt);

<p>1) Is indexing an array has same speed as indexing a list?</p>

3,515,148 | 3,515,149 | Should the "sub"-activities in a TabActivity bind services? | <p>I am building an application based on a tabbed activity. There are about 12 tabs at any given time.</p>
<p>I have built a download service, for my own use, which requires binding to it. I've found a few questions about the issue binding Services from tabs, but I haven't found anything discussing the best way to design this.</p>
<p>My paths seem to be:</p>
<ol>
<li>Bind the download service in the tab's activities using getParent() or getApplicationContext() as the context to bind to.</li>
<li>Bind the download service once in the TabActivity and then expose it via a static method to other Activities making up the tabs.</li>
<li>Redesign the download service so that it does not require binding. (I'm not really sure this is a viable option or buys me much)</li>
</ol>
<p>I'm basically in a toss up between 1 and 2. It seems like #1 seems to make the activities more independent, but I'm not sure if its going to cause problems having the tab "sub" activities binding the same service 12 times on the tab activitie's context. Similarly, I'm not sure if it is good practice to expose state-dependent objects, like a Service, via a static method to other Activities. I'm concerned it may create a number of race conditions that need to be accounted for depending on when the binding happens and when the tab activities are started.</p>
<p>What seems like the better design?</p>
