Answer 1

To get latest benefits in Android BOSH you need Smack Releases 4.1.1

SMACK --- smack-tcp smack-sasl-provided smack-resolver-minidns smack-resolver-dnsjava smack-extensions smack-core smack-bosh smack-android-extensions smack-android

You additionally Need

XPP3 1.1.4c delete the javax package from the JAR file for android because android already have javax....QName class

JXMMP, JXMMP CACHE, JBOSH, MINIDNS, DNSJAVA, JSTUN, XBILL DNS

No need for Apache HTTP Client which is already available in android

Unfortunately it comes around some 12 JAR files, better use Maven Android Project in Eclipse

Otherwise search the above keywords at Maven Central http://search.maven.org/#search and get the JAR files one by one

Answer 2

stack trace

java.lang.ClassNotFoundException: org.xmlpull.v1.XmlPullParserFactory
    at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1720)
    at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1571)

    at org.jivesoftware.smack.ConnectionConfiguration.<init>(ConnectionConfiguration.java:67)

The exception here clearly states that Webapp cant find class org.xmlpull.v1.XmlPullParserFactory. That sounds like you are missing xml-apis library in your classpath, (or some other implementation of XmlPullParser interface).

I had a similar problem. I donwload all the smack github I import smack.jar from /lib/ and add the 3 java files from /src/main/java/org/jivesoftware/smack/

I tried to fix it by importing smack-bosh-3.2.2-jar-with-dependencies.jar from /target/. I don't know why this diddn't work.

Finally, I read here that you need to download all the dependencies libraries : jbosh-0.6.0.jar xlightweb-2.5.jar xSocket-2.4.6.jar xpp3-1.1.3.3.jar dom4j-1.6.1.jar

So I used smack.jar from /lib/ with all thoses libraries and this problem was solved.

As i said in comments, you need after to retreive RID. I used jbosh sources and add following lines :

In com.kenai.jbosh.BOSHClient class
//I introduced a new property
private Long rid;

//commented the following code
//long rid = requestIDSeq.getNextRID();
//and at that place added
this.rid = requestIDSeq.getNextRID();

//and finally added a new getter for rid
public Long getRid() {
    return rid;}

Then in smack-bosh :

In BOSHConnection.java
public Long getRid() {
    return client.getRid();}
public String getSid() {
    return sessionID;}

Now I'm blocked cause my session is disconected. According to my openFire logs, it's because of overactivity. So I'm looking for a solution to reduce the number of presence messages.
