This happens to me when my computer came out standby. Restart your virtual device.

I was having the same problem in my Genymotion emulator while running a webview based application,I have restarted the emulator and it worked fine

How can I preallocate an array of structs in MATLAB? I want to preallocate &quot;a&quot; in this example so that it does not resize several times.

    a = []
    for i = 1:100
      a(i).x = i;
    end

I am trying to load a CSV file into a Hive table like so:

    CREATE TABLE mytable
    (
    num1 INT,
    text1 STRING,
    num2 INT,
    text2 STRING
    )
    ROW FORMAT DELIMITED FIELDS TERMINATED BY &quot;,&quot;;

    LOAD DATA LOCAL INPATH &#39;/data.csv&#39;
    OVERWRITE INTO TABLE mytable;    
&lt;br /&gt;
The csv is delimited by an comma (,) and looks like this:

    1, &quot;some text, with comma in it&quot;, 123, &quot;more text&quot;

This will return corrupt data since there is a &#39;,&#39; in the first string.&lt;br/&gt;
Is there a way to set an text delimiter or make Hive ignore the &#39;,&#39; in strings?

I can&#39;t change the delimiter of the csv since it gets pulled from an external source.

I am trying to run a simple OpenGL program in Android. I am running this in an Android 4.1 emulator. I switched on its GPU emulation and it worked fine yesterday. When I ran that today, initially it was hanging saying, `OpenGL taking time to render - Wait or Close dialog box`. After few runs again it was crashing saying

    E/EGL_emulation(2637): Failed to establish connection with the host

followed by

Thanks in advance. :)

Working on a website that is also viewable on mobile and need to bind an action on both touchstart and mousedown. 

Looks like this

     $(&quot;#roll&quot;).bind(&quot;mousedown touchstart&quot;, function(event){
    
     someAction();

It works fine on Iphone, but on Android it responds twice.

    event.stopPropagation();
    event.preventDefault();

Adding this code fixed it for Android Chrome, but NOT for Android default browser. Any other tricks that can fix the problem for all android?

I want to set the minimum date the user can choose in a DatePicker to the current date. I&#39;ve tried this:

    DatePicker datePicker = (DatePicker) findViewById(R.id.event_date);

That gives me the following exception:

In my app, the user will start with a single view of his data.  I&#39;d like to add a ViewPager and allow the user to add more views as desired.  How do I do this?  (I dont&#39; want to use the FragmentPagerAdapter.)

I&#39;ve read countless posts and overviews but am still missing something.  Here&#39;s what I think I understand:

MainActivity creates a ViewPager and PagerAdapter:

    ViewPager pager = null;
    MainPagerAdapter adapter = null;
    public void onCreate (Bundle savedInstanceState)
    {
      super.onCreate (savedInstanceState);
      pager = new ViewPager (this);
      setContentView (pager);

      adapter = new MainPagerAdapter();
      pager.setAdapter (adapter); 

      View v0 = code_to_create_initial_view();
      adapter.add (v0, 0);      
    }

Use a PagerAdapter to provide the sets of view.  For this it seems I need methods to add and remove views, something like this; obviously more is needed to tell the ViewPager stuff has changed and how to show the change:

    class MainPagerAdapter extends PagerAdapter
    {
      // This holds all the currently displayable views, in order from left to right.
      private ArrayList&lt;View&gt; views = new ArrayList&lt;View&gt;();
    
      public void addView (View v, int position)
      {
        views.add (position, v);
      }
    
      public void removeView (int position)
      {
        views.remove (position);
      }
    }

In addition, I need to implement the following vitual methods.  I&#39;m lost here - what calls them and what are they supposed to do (ok, getCount is obvious)?  

      public object instantiateItem (ViewGroup pager, int position);
      public void destroyItem (ViewGroup, int, Object);
      public int getCount ();
      public boolean isViewFromObject (View, Object);

- What are the ViewGroup params for - isn&#39;t the containing group the ViewPager itself?  
- What does isViewFromObject do - how does an object get associated with a view in the first place?
- Should I be calling startUpdate and finishUdate when I add or remove views?

Thanks.

I have the following layout (virtually empty):

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
    &lt;LinearLayout xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
        android:id=&quot;@+id/set_layout&quot;
        android:layout_width=&quot;fill_parent&quot;
        android:layout_height=&quot;fill_parent&quot;
        android:contentDescription=&quot;content desc&quot;
        android:orientation=&quot;vertical&quot; &gt;
      
        &lt;TextView android:id=&quot;@+id/text&quot;
              android:layout_width=&quot;wrap_content&quot;
              android:layout_height=&quot;wrap_content&quot;
              android:text=&quot;Hello, I am a TextView&quot; /&gt;
    &lt;/LinearLayout&gt;


The Activity class contains the following:

    public class TestActivity extends Activity {
      public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_test);   
      }
    }

When I run this on my mobile device I get the following error:

    SpannableStringBuilder
    SPAN_EXCLUSIVE_EXCLUSIVE spans cannot have a zero length

I have tried this with and without the TextView and the error still remains, I must be doing something fundamentally wrong for such a basic layout to cause this. 

Does anyone have any ideas on how I can get this to load without the error?

In the [learningwebgl tutorial1](http://learningwebgl.com/blog/?p=28) I&#39;ve found an interesting line in the fragment shader.

    precision mediump float;


I&#39;ve found an article about it [here](http://updates.html5rocks.com/2011/12/Use-mediump-precision-in-WebGL-when-possible), but I still can&#39;t understand what does it mean?

And if I remove this line, nothing changes. Everything is the same.
So what does `precision mediump float` mean?

I am working on an opengl project. 
I have used some images (2 for x-y scales) and labels (8) to display the scale on the screen. 
My first view is a `tableview` from which I go to `openglView`. But whenever I go back from `openglView` to the `tableView` it gives me this error and app crashes. 

**&quot;This UIView seems to be the delegate of an NSISVariable it doesn&#39;t know anything about. This is an internal UIKit bug.&quot;**

ANY Suggestions?
Is this happening because I am including too many UI elements, other than those images and labels I have used some buttons also. And I am applying `affineTransform` to those images and labels and one button also.


**Exact error is:**
