If you go into your Manifest file and set

        &lt;uses-sdk android:minSdkVersion=&quot;3&quot; /&gt;

to

        &lt;uses-sdk android:minSdkVersion=&quot;4&quot; /&gt;

Then you will have changed your entire project from running 1.5 as a minimum to 1.6.

While you are still building your app, you can change the minimum API level at any time. 

Using Android Studio, you would find `minSdkVersion` in the `build.gradle` file under `app` directory.

The answers regarding uses-sdk are no longer true in Intellij.

Now `&lt;uses-sdk&gt;` is ignored in the AndroidManifest.xml, it is automatically added to the built manifest file.  To change the version, go to the &#39;build.gradle&#39; file and look at the minSdkVersion.


Yes, go to your manifest and change `&lt;uses-sdk android:minSdkVersion=&quot;3&quot; /&gt;` to `&lt;uses-sdk android:minSdkVersion=&quot;4&quot; /&gt;`. Then go to Project &gt; Properties &gt; Android and change the Project Build Target to 1.6 to recognize new API code introduced in 1.6.

Change the following line in your **AndroidManifest.xml** file

        &lt;uses-sdk android:minSdkVersion=&quot;8&quot; /&gt;

Just think of minSdkVersion as your targeted API number.



Keep in mind that this could cause some older devices not run your application.

In Intellij version of Android Studio, you can just go to Gradle Scripts&gt;build.gradle(Module:app) then changing this line 

&gt; minSdkVersion 12

to the number of version you desire.



*In Android Studio you will find  the minSdkVersion/targetSdkVersion in the build.gradle (module:app)file under the Gradle Scripts Directory. Edit the build version here and then open the Manifest file to Synch the changes made.*

When calling Max() on an IQueryable and there are zero records I get the following exception.

**The cast to value type &#39;Int32&#39; failed because the materialized value is null. 
Either the result type&#39;s generic parameter or the query must use a nullable type.**

    var version = ctx.Entries
        .Where(e =&gt; e.Competition.CompetitionId == storeCompetition.CompetitionId)
        .Max(e =&gt; e.Version);

Now I understand why this happens my question is how is the best way to do this if the table can be empty. The code below works and solves this problem, but its very ugly is there no MaxOrDefault() concept?


    int? version = ctx.Entries
        .Where(e =&gt; e.Competition.CompetitionId == storeCompetition.CompetitionId)
        .Select(e =&gt; (int?)e.Version)
        .Max();

I need a comparator as part of a strategy pattern that can either use the natural ordering of the objects or some custom ordering. For the natural ordering case, I wrote a simple comparator:

    private static class NaturalComparator&lt;T extends Comparable&lt;? super T&gt;&gt; implements Comparator&lt;T&gt; {
        @Override
        public int compare(T o1, T o2) {
            return o1.compareTo(o2);
        }
    }

Seems simple enough, but I was wondering if anyone knew of one in the standard API. I looked at TreeMap, and it does it without such a class, so when that code was written, the apparent answer would be no, but perhaps it was added later.

Does a natural comparator exist in the standard api?

I selected API minimum level 1.5 for my android app and I&#39;m just about to integrate gestures in to it which came in 1.6. Is there a way in Eclipse to change the minimum level from 1.5 to 1.6 halfway through building an app?

Many thanks

I have been trying to get my EditText box to word wrap, but can&#39;t seem to do it.

I have dealt with much more complicated issues while developing Android applications, and this seems like it should be a straightforward process.

However, the issue remains, and I have a large text box that is only allowing me to enter text on one line, continuing straight across, scrolling horizontally as I enter text.

Here is the XML code for the EditText object from my layout file.

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
    &lt;LinearLayout
        android:id=&quot;@+id/myWidget48&quot;
        android:layout_width=&quot;fill_parent&quot;
        android:layout_height=&quot;wrap_content&quot;
        android:orientation=&quot;vertical&quot;
        xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
        &gt;
     &lt;ScrollView
        android:id=&quot;@+id/myScrollView&quot;
        android:layout_width=&quot;fill_parent&quot;
        android:layout_height=&quot;wrap_content&quot;
        android:layout_weight=&quot;1&quot;
        &gt;
        &lt;LinearLayout
            android:id=&quot;@+id/widget37&quot;
            android:layout_width=&quot;fill_parent&quot;
            android:layout_height=&quot;wrap_content&quot;
            android:orientation=&quot;vertical&quot;
        &gt;
    
    &lt;EditText
            android:id=&quot;@+id/txtNotes&quot;
            android:layout_width=&quot;300px&quot;
            android:layout_height=&quot;120px&quot;
            android:scrollbars=&quot;vertical&quot;
            android:textSize=&quot;18sp&quot;
            android:gravity=&quot;left&quot;
            android:layout_marginTop=&quot;10dip&quot;
            android:inputType=&quot;textCapSentences&quot;
            &gt;
        &lt;/EditText&gt;
    &lt;/LinearLayout&gt;
    &lt;/ScrollView&gt;
    &lt;/LinearLayout&gt;



Android Word-Wrap EditText text

I have an Edit Text that is defined as follows.

    &lt;EditText  
    android:layout_width=&quot;fill_parent&quot; 
    android:layout_height=&quot;wrap_content&quot;
    android:maxLines=&quot;1&quot;
    android:inputType=&quot;text&quot; 
    android:hint=&quot;@string/field_text&quot;
    android:id=&quot;@+id/field&quot;
    /&gt;

I want to set a custom command so that when somebody clicks on the Done/Go button on the onscreen keyboard a button is clicked or just run the methods that are run by the button. I think this has something to do with ime options but I havent been able to figure out how they work. Thanks in advance for any help!

Is it possible when creating a _RelativeLayout_ at runtime to set the equivalent of `android:layout_below` programmatically?

Can I Set &quot;android:layout_below&quot; at Runtime Programmatically?

I&#39;ve a `RelativeLayout` thus:

    &lt;RelativeLayout&gt;
    &lt;TextView1/&gt;
    &lt;TextView2/&gt; // &lt;-- View.VISIBLE OR View.GONE
    &lt;TextView3/&gt;
    &lt;TextView4/&gt;
    &lt;/RelativeLayout&gt;

Each `TextView` is anchored below the previous `TextView` with `android:layout_below`.

The problem is that TextView2 may or may not be there (either `View.VISIBLE` or `View.GONE`); if it&#39;s `View.VISIBLE`, then all is fine, but if it&#39;s `View.GONE`, then TextView3 ends up being rendered on top of TextView1.

I&#39;ve tried various ways to fix this, but each time am caught out by `RelativeLayout`&#39;s &#39;you cannot reference an id before it&#39;s defined&#39; rule.

I&#39;m hoping that I&#39;m missing something obvious here.

What is the proper/preferred way to allocate memory in a C API?

I can see, at first, two options:

1) Let the caller do all the (outer) memory handling:

    myStruct *s = malloc(sizeof(s));
    myStruct_init(s);

    myStruct_foo(s);

    myStruct_destroy(s);
    free(s);

The `_init` and `_destroy` functions are necessary since some more memory may be allocated inside, and it must be handled somewhere.

This has the disadvantage of being longer, but also the malloc can be eliminated in some cases (e.g., it can be passed a stack-allocated struct:

    int bar() {
        myStruct s;
        myStruct_init(&amp;s);

        myStruct_foo(&amp;s);

        myStruct_destroy(&amp;s);
    }

Also, it&#39;s necessary for the caller to know the size of the struct.

2) Hide `malloc`s in `_init` and `free`s in `_destroy`.

Advantages: shorter code, since the functions are going to be called anyway. Completely opaque structures.

Disadvantages: Can&#39;t be passed a struct allocated in a different way.

    myStruct *s = myStruct_init();

    myStruct_foo(s);

    myStruct_destroy(foo);

I&#39;m currently leaning for the first case; then again, I don&#39;t know about C API design.

Recently, I read this article:
http://download.oracle.com/javase/tutorial/extra/generics/wildcards.html

My question is, instead of creating a method like this:

	public void drawAll(List&lt;? extends Shape&gt; shapes){
	    for (Shape s: shapes) {
	        s.draw(this);
	    }
	}

I can create a method like this, and it works fine:

	public &lt;T extends Shape&gt; void drawAll(List&lt;T&gt; shapes){
	    for (Shape s: shapes) {
	        s.draw(this);
	    }
	}

Which way should I use? Is wildcard useful in this case?


Java: bounded wildcards or bounded type parameter?

Whenever I ask people about the difference between an API and a library, I get different opinions.  Some give [this kind][1] of definition, saying that an API is a spec and a library is an implementation...

Some will tell you [this type][2] of definition, that an API is a bunch of mapped out functions, and a Library is just the distribution in compiled form.

All this makes me wonder, in a world of web code, frameworks and open-source, is there really a practical difference anymore?  Could a library like jQuery or cURL crossover into the definition of an API?  

Also, do frameworks cross over into this category at all?  Is there part of Rails or Zend that could be more &quot;API-like,&quot; or &quot;libraryesque&quot;?

Really looking forward to some enlightening thoughts :)

We are thinking on moving our Rest API Server (it is inside the web service, on Symfony PHP) to Scala for several reasons: speed, no overhead, less CPU, less code, scalability, etc. I didn&#39;t know Scala until several days ago but I&#39;ve been enjoying what I&#39;ve been learning these days with the Scala book and all the blog posts and questions (it&#39;s not so ugly!)

I have the following options:

 - build the Rest API Server from scratch
 - use a tiny Scala web framework like [Scalatra][1]
 - use Lift

Some things that I will have to use: HTTP requests, JSON output, MySQL (data), OAuth, Memcache (cache), Logs, File uploads, Stats (maybe Redis).

What would you recommend?
