How to wait for an activity to finish in asynctask

I know that the purpose of the AsyncTask is to run asynchronously with other tasks of the app and finish in the background, but apparently I need to do this, I need to start an activity from AsyncTask and since I cant extend an activity in this class I can not use startactivityforresult, so how can I wait till my activity finishes?
Here is my code:
public class ListSpdFiles extends AsyncTask<Void, Void, String[]> {
public AsyncResponse delegate = null;
private static final String TAG = "ListSpdFiles: ";
Context applicationContext;

};

Remove
if (pDialog.isShowing())
and
use if (pDialog != null)
may this help you

You should remove super.onPostExecute(result); as you have your implementation of onPostExecute(), so you may not want framework to handle it.
Since you have definitely showed the Progress Dialog in onPreExecute(), then you can also omit check for isShowing(), but i will recommend you to keep this check as it causes no harm and adds little more security.

In your onPostExecute() block you are calling super.onPostExecute(result);
#Override
protected void onPostExecute(Void result) {
super.onPostExecute(result);
// Your code
}
However as you are overriding the onPostExecute() there is no need to call super.onPostExecute(result);
If you take a look at the AsyncTask source, you will see that the super class does nothing:
#SuppressWarnings({"UnusedDeclaration"})
protected void onPostExecute(Result result) {
}

Display PDF in fragments within app android

In my app, I have to display PDF file from sdcard in android. The app uses tab functionality so I have used fragments in my app. So how to display pdf file inside fragments?
I have used pdfviewer.jar, but I am not able to display inside fragments, it only works in activity.
And another question is I want to display pdf with multi-zoom and vertical page scrolling to see next/previous pages, not by manually clicking on zoom icon and arrow icon to see next page which is used in pdfviewer.jar.

I am giving the full code below of that changed fragment. I did it 3 years back and that time Sherlock library was used. I think now you have to replace that by appcompat library.

Your best bet is to use the Google API Client library:
http://code.google.com/p/google-api-java-client/wiki/Setup
Download the core jars(link to be found in the wiki) and dependencies. In particular, you should be looking for these jars:
google-api-client-version-alpha.jar
google-api-client-googleapis-version-alpha.jar
guava-version.jar
jackson-core-asl-version.jar
Next. set up your model classes that describe your feed. For DocList, refer this sample:
Google API DocList Sample
DocUrl.java, DocumentListEntry.java, DocumentListFeed.java, Entry.java, Feed.java & Link.java are the model classes which should set you up.
Next, initialize your HTTPTransport by choosing the parser i.e. Atom/Json and fire your request.
public static final XmlNamespaceDictionary NAMESPACE_DICTIONARY = new XmlNamespaceDictionary();
static {
NAMESPACE_DICTIONARY.set("", "http://www.w3.org/2005/Atom");
NAMESPACE_DICTIONARY.set("app", "http://www.w3.org/2007/app");
NAMESPACE_DICTIONARY.set("batch", "http://schemas.google.com/gdata/batch");
NAMESPACE_DICTIONARY.set("docs", "http://schemas.google.com/docs/2007");
NAMESPACE_DICTIONARY.set("gs", "http://schemas.google.com/spreadsheets/2006");
NAMESPACE_DICTIONARY.set("gd", "http://schemas.google.com/g/2005");
NAMESPACE_DICTIONARY.set("gsx", "http://schemas.google.com/spreadsheets/2006/extended");
NAMESPACE_DICTIONARY.set("openSearch", "http://a9.com/-/spec/opensearch/1.1/");
NAMESPACE_DICTIONARY.set("xml", "http://www.w3.org/XML/1998/namespace");
}
private static HttpTransport transport;
private void setupTransport() {
transport = new NetHttpTransport();
GoogleHeaders headers = new GoogleHeaders();
transport.defaultHeaders = headers;
headers.setApplicationName("MyApp/1.0");
headers.gdataVersion = "3.0";
((GoogleHeaders) transport.defaultHeaders)
.setGoogleLogin(<yourtoken>);
AtomParser parser = new AtomParser();
parser.namespaceDictionary = Util.NAMESPACE_DICTIONARY;
transport.addParser(parser);
}
public processDocs() {
setupTransport();
DocUrl url = DocUrl.relativeToRoot(<URL suffix>);
DocListFeed feed = DocListFeed.executeGet(transport, url);
if (feed.entries != null) {
for (DocEntry entry : feed.entries) {
//<do whatever>
}
}
