I have used this link to preform videoChat.However, it gives me java.lang.NoClassDefFoundError which cannot locate : com.quickblox.module.chat.smack.SmackAndroid class .I tried changing the preferences of libraries but din't helped.
Here is the log:

Numbers are treated as doubles, so resulting numbers will contain at least one decimal place.
string String can also be added together, compared, etc...
Boolean Expression that evaluate to true (1.0) and false (0.0).
functional Custom functions can be created or there are many Math and String functions that JEval supplies with this class.
i am testing the sdk samples app from alfresco android sdk under a AVD, i am using alfresco community edition 4.2, when i enter a wrong Hostname i get the message "failed to log in. please check your settings", but when i enter the correct host name, the app crashes and i get the message "Unfortunately, SDK Samples has stopped." then it restarts...
there is this one time, i entered the correct host name and the app connected to the alfresco server without any problem, but when i tried a second time the problem persists
any idea what could be the problem?!!

This error was due to a bug inside a dependency used by Alfresco Mobile SDK Sample.
This error has been fixed by the release of alfresco-opencmis-extension 0.7-ANDROID and in general by the release of Alfresco Mobile SDK 1.3.1.
I'm trying to follow the advice from this post:
But when I run this code, my program crashes. Here is my code:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
/* Change the font for the password hint to match that of the
* user name field */
EditText pw = (EditText) findViewById(R.id.password);
pw.setTypeface(Typeface.DEFAULT); //<---Crashes on this line
pw.setTransformationMethod(new PasswordTransformationMethod());
setContentView(R.layout.activity_main);
}
Here is the XML for this object:
<EditText
android:id="#+id/password"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/userName"
android:layout_alignRight="#+id/appName"
android:layout_below="#+id/userName"
android:layout_marginTop="14dp"
android:ems="10"
android:hint="#string/password"
android:inputType="textPassword" />
And finally, here is the LogCat output where I can see the error:

Can't figure out what is going wrong. Can anybody see it? Thanks!
Change the call of setContentView(R.layout.activity_main);
Call it just after super.onCreate(savedInstanceState);
When you're doing EditText pw = (EditText) findViewById(R.id.password);, findViewById "can't retrieve" the EditText that you have defined in your layout (because you call setContentView after) so findViewById returns null and when you're doing pw.setTypeface(Typeface.DEFAULT); it throws a NPE because pw is null.
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...
In my app there is one activity I have where I call onDestroy and inside it I have the following:
#Override
public void onDestroy()
{
productAdapter.imageLoader.stopThread();
lvProducts.setAdapter(null);
super.onDestroy();
}
productAdapter is my ListView adapter and I am using the fedorvlasov lazy load functionality.
The issue is, when I leave the app for a LONG time and come back, I try to access this activity from the main activity and I get the following:
03-22 09:15:17.684: ERROR/AndroidRuntime(28442): FATAL EXCEPTION: main

The thing is, I dont know how to reproduce this because it only happens if I leave the app for a long time and come back. Its almost like there is an Android timeout that says after this many hours, cause app to start over.
The system will kill your application whenever it needs the resources to use for something else. This is why when you come back after a long time it is no longer running.
why do you have this line?
lvProducts.setAdapter(null);
I think that is what is giving you a null pointer. It isn't liking that you are trying to set it with a null adapter. Try removing this line
Also just to be sure, which line is 678?
