5,926,437 | 5,926,438 | Are inline if statements efficient when used in this way? | <p>If I assign a value to a variable and then want to assign a second value to it, but only if it fulfills a condition, is it just as efficient to use a shorthand if statement? Here is an example.</p>
<p>Is this more efficient</p>
<pre><code>int x = GetInt();
if (x < 5)
x = 5;
</code></pre>
<p>Than this</p>
<pre><code>int x = GetInt();
x = x < 5 ? 5 : x;

<p>I suppose that what I'm really asking is if <code>x</code> does not satisfy the condition then will the <code>x = x</code> in the else statement impact the performance?</p>

2,412,257 | 2,412,258 | Check whether function result value is used | <p>I was wondering whether it is possible to check whether a function is called in such a way that its return value is stored in a variable, or that it is called 'standalone'.</p>
<p>In the first case, the function should indeed return something, but otherwise it should save the value(s) to the current instance of my object.</p>
<p>To be specific, I have a <code>Vector3D</code> as follows:</p>
<pre><code>function Vector3D(x, y, z) {
this.x = parseNumber(x);
this.y = parseNumber(y);
this.z = parseNumber(z);
}
Vector3D.prototype.add = function(that) {
return new Vector3D(
this.x + that.x,
this.y + that.y,
this.z + that.z
);
};
</code></pre>
<p>As can be seen, the <code>add</code> function returns something based on the object instance itself and on another instance. As it is now, the function must be called in a way like this:</p>
<pre><code>var addedVector = vect1.add(vect2);
</code></pre>
<p>However, if I were to call it like this:</p>
<pre><code>vect1.add(vect2);
</code></pre>
<p>it should not return anything (that's quite useless), but instead store the return coordinates (<code>x</code>, <code>y</code> and <code>z</code>) in the variables of vect1. So vect1 should become what is called addedVector in the other line of code.</p>
<p>To accomplish this, I guess I'm going to need to know whether the function is called alone or that its return value is stored.</p>
<p>Is there any way to accomplish this?</p>

2,750,431 | 2,750,432 | How expensive is .getClass() in Java? | <p>I'm in the process of porting over a certain data processing algorithm from Java to C++. The reason for re-writing the code is portability, it needs to run in environments where Java is not available. However, as a side benefit some performance improvement was expected.</p>
<p>Basically, the algorithm reads data from a graph made up of objects with pointers to each other and then computes a result. During the computation numerous object allocations are made, so perhaps this is responsible for the slowdown. The thing is, the C++ code currently runs about 10 times faster than the old Java code. This was really unexpected. I only thought I'd see an improvement of maybe 50-60%.</p>
<p>Unfortunately, I'm not at liberty to post the code here for analysis. It's several thousand lines, so I'm not sure how convenient that would be anyway.</p>
<p>The thing is, the algorithm is almost exactly the same. The only major difference I can think of is in Java there are many daughter classes of a single super class and if(object.getClass() == daughterx.class) is called many times during the computation whereas in the C++ code only one general class is used (since there are few code differences between the daughter classes) and a simple integer comparison is used eg. if(object->type == 15)</p>
<p>How expensive is the Object.getClass() method in Java? What exactly is happening at the low-level when this method is invoked?</p>

2,404,349 | 2,404,350 | Difference between "force stop" and leaving the phone for a few hours | <p>I've had a couple of game apps on the market which attempt to save the users progress through the game with some code like this (simplified):</p>
<pre><code>public class Globals extends Application
{
public void onCreate()
{
settings = getSharedPreferences("MyPrefsFile", 0);
}
public void get_state()
{
synchronized (this)
{
game_progress = settings.getInt("progress", 1);
}
}
public void save_state()
{
synchronized (this)
{
SharedPreferences.Editor editor = settings.edit();
editor.putInt("progress",game_progress);
editor.commit();
}
}
}
</code></pre>
<p>This appears to work fine 99% of the time but every now and then I have had reports from users that their progress was lost, but nobody has ever been able to give me a sequence of actions which will enable me to repeat the bug... until now. The steps involve pressing the "home" button to exit the program and then waiting several hours. Then when they run the game again, their progress is lost. Frustratingly this sequence can not be shortened, doing a "force stop" instead of leaving the phone for several hours does not have the same effect.</p>
<p>Presumably if the phone is left for a few hours, some or all of the activities within the application may get shut down in a way which is subtly different from a force stop... but I have no idea how.</p>
<p>Any ideas?</p>
<p><strong>EDIT:</strong> I should explain how these functions are called from the various activities that comprise my games. Here's an example, but I call gs.save_state() from several other places too, just for good measure.</p>
<pre><code> public class Main_GamePlay extends Activity
{
Globals gs;
public void onCreate(Bundle savedInstanceState)
{
gs = ((Globals) getApplicationContext());
}
protected void onPause()
{
gs.save_state();

4,632,488 | 4,632,489 | framework.jar is updated properly , but contact code is using old value | <p>let me explain my question:
I have separated contact app from ICS. which is installed in my simulator. This app uses "RawContacts.CONTENT_URI" in many places in code base, which is defined in "frameworks/base/core/java/android/provider/ContactsContract.java". Now my purpose is to change the value of of "CONTENT_URI", so that whenever it is used in Contact code base it will get this newly assigned value.</p>
<h1>So I changed the in the framework code</h1>
<p>public final class ContactsContract {
/** The authority for the<code>enter code here</code> contacts provider */
public static final String AUTHORITY = "com.android.xyz.contacts";
=========================================================================
then i full build ICS 4.0.3 and then use the framework.jar in my Separated Contact app so that when ever Contacts refers "RawContacts.CONTENT_URI" it gets updated value , i.e. "content://com.android.xyz.contacts/raw_contacts". </p>
<p>BUT the problem is When I run my separated Contact app I am getting "content://com.android.contacts/raw_contacts". as a value of "RawContacts.CONTENT_URI". though ContactsContract.class file is updated with "content://com.android.xyz.contacts/raw_contacts". I think I make u understand my problem. Thanks</p>

3,446,233 | 3,446,234 | Disabling Android home button for industry application | <p>I'm writing an industry application which will be used by traffic wardens to register offences through my program using forms.</p>
<p>The app is using a webview so it is just a container for an external webpage. We don't want our users to exit the application so we have to disable all buttons. I succeeded in disabling them except for the home button.</p>
<p>I read some threads about this topic, but I don't have any solutions yet. The idea is that I am able to make the app the default home app so if the user presses the home button it launches my app and does not exit. How can I accomplish that? If we must we are able to tamper with android itself (when we install the app), but if there is some solution through configuration it would be appreciated.</p>
