You cannot display an application window/dialog through a Context that is not an Activity. Check please that every time you start a dialog it gets correct Context.

The java.lang.ClassNotFoundException seems like can't find your Main Class, it could be a name problem of your java main class or in config.xml or in manifest, check all names are correctly.

What would be the possible main cause of this errors?
title might be null here.
Also change
title.setText(R.string.title_notConnected);
to
title.setText(getString(R.string.title_notConnected));

Thanks guys :)
If I counted right this
ibHome3 = (Button) findViewById(R.id.ibHome3);
is causing your problem. You have it as an ImageButton in your xml but Button in your java declaration. Just change it to
ImageButton ibHome3;
About Logcat
Also, just a little advice on logcat. If you find the first line that says Caused By after Fatal Exception you can track down your problem easier. Here it is
Caused by: java.lang.ClassCastException: android.widget.ImageButton cannot be cast to android.widget.Button
this gives the exception
java.lang.ClassCastException
then find the first line after that which references your package. Here
at com.jumoun.itemp.Converter.onCreate(Converter.java:41)
this tells us the problem starts in Converter.java at line 41
You have two buttons in your layout file, right? They looks to be defined as ImageButton in the XML file. In your Activity, you declare it as Button and try to convert with a cast to (Button). Change your type to ImageButton on your Activity file. It may solve your prolbem.
On line 41, you have to cast your button to ImageButton and not Button :
ibHome3 = (ImageButton) findViewById(R.id.ibHome3);
Here's my code. I am trying to set background of a linear layout. But this xml (rowback) is not my main activity content, so gives errors. how can I set some XML from the class which doesn't have that XML in its content?
setContentView(R.layout.activity_quick_search_products);
...
rowb = (LinearLayout)findViewById(R.id.rowback);
...
final Drawable d = getResources().getDrawable(R.drawable.denemebut3);
d.setAlpha(100);
rowb.setBackgroundDrawable(d);

If R.id.rowback doesn't belong to your main activity xml resource, then you should inflate that resource manually using:
LinearLayout rowb = (LinearLayout) getLayoutInflater().inflate(XML file that contains R.id.rowback, null);
then you can safely do
rowb.setBackgroundDrawable(d);
As an extra, if you have nested elements in rowback then you can invoke:
rowb.findViewById(R.id.Something) safely.
Or if your class is not exteding from any Activity, you can always receive a Context object in its constructor, and then use
LayoutInflater.from(context)
to get a LayoutInflater object so you can inflate any XML resource you need that is not actually in your main content.
Hope this clarifies...

You have to add ksoap2 library to your classpath as an external library and also copy the .jar into libs folder of the project.
