<p>I have noticed that the Map Tiles used in the MapView class are not as high-res as the tiles used in the real Android Google Maps app (I have a Droid). I have searched the docs and google, but I cannot find any info on this. Actually, I can't even find anyone mentioning this, which surprises me and makes me think I am missing something simple. Is this a case of Google making the APIs available, but at a lower quality, or am I missing some setting that enables higher quality map tiles?</p>

I have only one image for each tab, so I was wondering if there is way to just change the color of the image alone (as opposed to changing the tab's color) when a tab is selected?

40,519 | 40,520 | Pointer type without delete operator | <p>Is it possible to construct a pointer type that acts and behaves (in terms of syntax) like a normal pointer, except that you can't call delete on it (perhaps with preprocessor macros)?</p>
<p>Example usage:</p>
<pre><code>borrowed_ptr<int> ptr = new int[42];
ptr[12] = 1;
cout<<ptr[12]<<endl; //prints 1
delete ptr; //error: no operator delete for borrowed_ptr<int>
borrowed_ptr<int> ptr2 = new int(2);
delete ptr2; //error
</code></pre>
<p>Also this should work too</p>
<pre><code>template<typename t>
void func(borrowed_ptr<t> *arg)
{
delete arg; //error
}
//somewhere else
int *t = new *int;
func(t);
</code></pre>
<p>However, "reverse assignement" shouldn't work.</p>
<pre><code>borrowed_ptr<int> foo = new int(2);
int* bar = foo; //error
</code></pre>
<p>Whether or not the * is required when declaring a borrowed_ptr doesn't matter to me. It's just important that code like</p>
<pre><code>template <typename T>
void foo(T* whatever)
{
//do something with whatever
delete whatever;
}
template <typename T>
void bar(T* whatever)
{
//do something with whatever
}
</code></pre>
<p>can be called with this borrowed_ptr like this:</p>
<pre><code>borrowed_ptr<int> a = new int(2);
foo(a); //error, function tries to delete
bar(a); //fine, and has the same semantics as handing over a raw int*
</code></pre>
<p>Note: i don't want the data deleted when the pointer type is delete itself. it should just be a borrowed ptr that can not be deleted because it belongs to someone else.</p>

4,647,487 | 4,647,488 | Android App will not function properly in production, but not receiving any errors or hints as to what is wrong | <p>I have been developing an app over the past 3-4 months. I am using eclipse with the Android SDK plugin. I have tested and tested and tested before releasing the app on the market. I finally decided that the app was ready and created a production certificate using the SDK tools through eclipse. Exported the project as an android app and submitted it to the market. The app needs to access a remote server to receive the information for the content of the app. I am not sure why, but for some reason the apk that is produced by exporting the project from eclipse always returns a login failure message. If I connect my device and install/run from eclipse using the same login credentials everything works just fine. What have I forgotten or done wrong?</p>

<p>What would be the best design for that? I know Iwould have an item listener and based on the selection, I would "do something".
Would I create layout with spinner and empty "linearlayout" below, then based on selection I would inflate another xml file into a view and add it to that layout? Or would create all the forms in one XML file and set all layout to hidden and show only the one corresponding to selection?</p>

<p>While debugging the code I discovered that a <code>.1</code> key appeared in <code>locals()</code>, with the value <code>(b1, b2)</code>. A quick check revealed that a function definition like the following:</p>
<pre><code>def f((a1, a2)):

<p>So what Im wondering is: Is there any standard header file that defines these types? Or is there some standard definitions that everyone uses that I should copy?</p>

<p>In Python, the term method is not
unique to class instances: other
object types can have methods as well.
For example, list objects have methods
called append, insert, remove, sort,

<p>One implication I can find is this gives an error: <code>[].foo = 'bar'</code>. Are there other implications? Why isn't list implemented as a class? Is this because of historic reasons?</p>

373,946 | 373,947 | How to draw drop-down shadows in iOS | <p>A CAShapeLayer uses a CGPathRef to draw it's stuff. So I have a star path, and I want a smooth drop shadow with a radius of about 15 units. Probably there is some nice functionality in some new iPhone OS versions, but I need to do it myself for a old aged version of 3.0 (which most people still use).</p>
<p>I tried to do some REALLY nasty stuff:
I created a for-loop and sequentially created like 15 of those paths, transform-scaling them step by step to become bigger. Then assigning them to a new created CAShapeLayer and decreasing it's alpha a little bit on every iteration. Not only that this scaling is mathematically incorrect and sucks (it should happen relative to the outline!), the shadow is not rounded and looks really ugly. That's why nice soft shadows have a radius.</p>
<p>The tips of a star shouldn't appear totally sharp after a shadow size of 15 units. They should be soft like cream. But in my ugly solution they're just as s harp as the star itself, since all I do is scale the star 15 times and decrease it's alpha 15 times. Ugly.</p>
<p>I wonder how the big guys do it? If you had an arbitrary path, and that path must throw a shadow, how does the algorithm to do that work? Probably the path would have to be expanded like 30 times, point-by-point relative to the tangent of the outline away from the filled part, and just by 0.5 units to have a nice blending.</p>
<p>Before I re-invent the wheel, maybe someone has a handy example or link?</p>

<p>Reasons of stop learning was</p>
<p>I was not having access to internet on that time so that I could asked questions.
There was not any source of motivation.
I was not able to implements the inheritance. Everyting I coded in one class or used compsition which demotivated me I used to think that it was useless code.
Most of example which explaine inheritance I understand very clearly but can not think that way during codeing.
Exercise was also not available. So major concepts was easy to remembor but for intricate details I had to consult book.</p>
<p>Two month ago I bought NoteII and I started learning android which is basically java and made examples from books by using eclipse.</p>
<p>And this time I donot want to discontinue learning.</p>
<p>MY question is
Is there a way or book which take me from basic of java language to advance level with plenty of excercises which not only shows language features but also make programmer implements that language features.</p>
<p>Most of the books shows language features and its rules and regulation. All books lacks in excercises. Language features learnning is not problum. There impementaion learning is a problum.</p>

1,339,345 | 1,339,346 | Sending data to webservice without using querystring in jQuery | <p>I have the following jquery using which I send some data to a webservice.</p>
<pre><code>var value1="This is val1";
var value2="This is val2";
$.ajax({
url: "Test.asmx/PostData",
data: { data1: value1, data2: value2 },
success: function (html) { strReturn = html; },
async: false
});
if (strReturn == "") {
//some error occured or the data did not get send to webservice
}
else
{
//The data is send to the webservice
}
</code></pre>
<p>Now the problem is that since the data is posted as query string. If the length of data in value1 & value2 are very long, The data is not send to the webservice.</p>
<p>How can I avoid sending the data using querystring. I've tried setting the ajax parameters "processData" as false and "type" as POST but still no luck.</p>
<p>It would be great if anyone could send me the jquery code on how this can be done.</p>
<p>Thanks in advance</p>

2,563,651 | 2,563,652 | dynamic row inserts - mysql php - how? | <p>Hy to all, </p>
<p>I have a misunderstanding regarding some dynamic row inserts in a mysql table...</p>
<p>All I want to do is based on the EAV Model : </p>
<ul>
<li>I have a products table wich contains products</li>
<li>A attributes table wich contains attributes (name) for products (group based - related to category)</li>
<li>And a product_attribute wich cotains the value of the attribute ...</li>
</ul>
<p>And the user must create this attributes to be associated with a product, and I'm thinking to insert <code><input></code> elements with jquery's <code>append</code>.</p>
<p>But how to track inserts and how to append them to have a specific name : <code><input name=''></code>.</p>
<p>The result shoul do the following :</p>
<pre><code><form action='attribute_insert.php' method='post'>
<input name='field1' />
<input name='field2' />
<input name='field3' />
....
<input name='field20' />
</form>
</code></pre>
<p>and after processing in <code>attribute_insert.php</code> to insert like this :</p>
<pre><code>('1', '12', 'manufacturer');
('2', '12', 'freq');
('3', '12', 'memory');
('4', '12', 'ram');
....
('20', '12', 'blablabla');
</code></pre>
<p>How can i do this ... using <code>foreach</code> to scan the <code>$_POST[]</code> or there is a clever method ?</p>
<p>Thank you very much ...</p>
