NullPointerException in get(url) method about google-voice-java

[GoogleCodeExporter]

Forgot to add, this NullPointer exception happens during the constructor:

voice = new Voice(uName, pass,"My-GoogleVoice",false,Voice.GOOGLE);

I've done a bit of investigating on this. It looks like Android's 
implementation of HttpURLConnection is based partially on Apache's Harmony 
project (which actually works on JDK 1.5, not v6). However, looking in their 
source did not reveal the correct line numbers, so this may required digging 
into the actual source for the Android system before this can be resolved. On 
our side it occurs when we call conn.getResponseCode(); in the get(urlString) 
method.

@gururise: Do you have the Android OS version for the users who are getting 
this exception?

19 reports came from the Verizon Droid in the past 2 weeks (v2.0+ but most of 
them are probably running v2.1 by now), and two reports came from a Nexus One 
(v2.1 or v2.2)

So all the reports came from Android v2.0 or Higher.

Any progress on this issue? Are the latest commits related to this?

My android app has thrown an Apache Harmony error perhaps similar to your error 
on Froyo emulation mode.  It is a problem certainly to be solved.

@gururise The latest change 
(http://code.google.com/p/google-voice-java/source/detail?r=118) may fix the 
problem for you. Are you able to replicate the problem yourself? I haven't had 
time to setup and Android 2.1 emulator to test the problem, but from what I'm 
reading, it may stem from timeouts on the connection, so I've added a forced 
connect each place in the code where we check the response code.

@liquidhot: I myself haven't seen the problem, but my users see the problem. 
I'll go ahead and push out the changes and see if the problem goes away. I'll 
let you know in a few days.

I should clarify my above statement.  The error still exists as of r118.

Original comment by [email protected] on 7 Jul 2010 at 4:26

[GoogleCodeExporter]

I can confirm that r119 still has this issue.

I uploaded a new jar 1.7 which was compiled with Jave 5.  Please test if the 
Apache Harmony error still exists with this version.  This is a shot in the 
dark, but please test it.

[GoogleCodeExporter]

I've always been using the source from SVN and compiling myself.  The last 
version of the source I used that exhibited this problem was r119.

I'll try using the jar 1.7 package instead and see if it makes the problem go 
away.

Using the jar 1.7 package results in the same NullPointerException:

OK, I actually think I compiled it incorrectly.  Please disregard request for 
testing.  Will try again later.

My Users are having the same problems - null pointer exception on the first get 
- doesnt happen evertime, though.
Will try compiling the svn with java5.

I checked in a piece of code which now checks if the input stream is null, and 
if so it throws an exception with the error code. Now its not a nullpointer but 
a real error. Here is what my first user report said:

Joseph - it would be interesting to see if the new version can handle the 302 
fine and see a log of that happening. That problem never occurred in my own 
tests.

Interesting - did you use the newest revision 123? 
http://code.google.com/p/google-voice-java/source/detail?r=123 
Line 1231 is this statement:
int responseCode = conn.getResponseCode();
which doesnt really make sense, because we have operated on conn before. Any 
thoughts? Are you able to debug this part?

The first Post had a line number where 'InputStream is' was null. This has been 
resolved. 
So should we close this issue and open a new one for your problem on revision 
123 com.techventus.server.voice.Voice.get(Voice.java:1231) ?

Yes, its with the latest revision 123.  I noticed this new NullPointerException
