ImageView showing up in debug mode, but not in run mode



My case is a little special.... I'm trying to get an image via tcp and make it show into my device screen.





Please, don't ask me to do it with another kind of way to get the image, since this is the only way i can do it, and that's not my issue.





What happens is that when i'm debuging step-by-step my program, the image shows up into my screen. But when i run it without debuging, it doesn't show up.





This is my main.xml:







<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:orientation="vertical"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

>

<TextView

android:id="@+id/textview"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:text="Hello World, MyActivity"

/>

<ImageView

android:id="@+id/imageview"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

/>

</LinearLayout>







and this is my MyActivity.java:







public class MyActivity extends Activity

{

/** Called when the activity is first created. */

@Override

public void onCreate(Bundle savedInstanceState) // Aquesta funcio es crida al començar, pero tambe cada vegada que es gira la pantalla.

{

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

}



@Override

public void onStart(){

super.onStart();



TextView tv = (TextView) findViewById(R.id.textview);



try {

Socket s = new Socket("ip-here", port-here);



DataInputStream ins = new DataInputStream(s.getInputStream());



int bytesRead = 0;

byte[] bSize = new byte[10];

while(bytesRead < 10){

bytesRead += ins.read(bSize, 0, 10 - bytesRead);

}

String sSize = new String(bSize);

Integer size = Integer.valueOf(sSize);



byte[] pic = new byte[size];

bytesRead = 0;

while(bytesRead < size){

bytesRead += ins.read(pic, 0, size - bytesRead);

}



Bitmap bitmapimage = BitmapFactory.decodeByteArray(pic, 0, bytesRead);

ImageView image = (ImageView) findViewById(R.id.imageview);

image.setImageBitmap(bitmapimage);



tv.setText(sSize + " -> #" + size + "# -> #" + bytesRead + "#");

} catch (IOException e) {

e.printStackTrace();

tv.setText("error de IO");

}

}

}







Additional information: The TCP server sends a 10-char string containing the size of the image (in base 10). And then the whole image in jpg format.





As you can see, i put a Textbox to tell me what's happening, and it's ok. Even when i run it, it says he got the whole image, but it just doesn't show up...





Am i missing something? maybe i shouldn't put this code in the onStart() method?





Thank you, Víctor

Why is this Javascript much *slower* than its jQuery equivalent?

I have a HTML list of about 500 items and a "filter" box above it. I started by using jQuery to filter the list when I typed a letter (timing code added later): $('#filter').keyup( function() { var jqStart = (new Date).getTime(); var search = $(this).val().toLowerCase(); var $list = $('ul.ablist > li'); $list.each( function() { if ( $(this).text().toLowerCase().indexOf(search) === -1 ) $(this).hide(); else $(this).show(); } ); console.log('Time: ' + ((new Date).getTime() - jqStart)); } ); However, there was a couple of seconds delay after typing each letter (particularly the first letter). So I thought it may be slightly quicker if I used plain Javascript (I read recently that jQuery's each function is particularly slow). Here's my JS equivalent: document.getElementById('filter').addEventListener( 'keyup', function () { var jsStart = (new Date).getTime()...

Is it possible to have IF statement in an Echo statement in PHP

Thanks in advance. I did look at the other questions/answers that were similar and didn't find exactly what I was looking for. I'm trying to do this, am I on the right path? echo " <div id='tabs-".$match."'> <textarea id='".$match."' name='".$match."'>". if ($COLUMN_NAME === $match) { echo $FIELD_WITH_COLUMN_NAME; } else { } ."</textarea> <script type='text/javascript'> CKEDITOR.replace( '".$match."' ); </script> </div>"; I am getting the following error message in the browser: Parse error: syntax error, unexpected T_IF Please let me know if this is the right way to go about nesting an IF statement inside an echo. Thank you.
