What steps will reproduce the problem? If response from server is huge, android device gives OutOfMemory Error

What version of the product are you using? On what operating system? ksoap 2.6.5 on Mac OSX Lion 10.7.3

Please provide any additional information below.

All data downloaded are saved on memory, so if xml response is huge any device can give this error. One possible solution can be giving possibility to save data directly on disk as an xml file for example.

If the file is to big to be parsed from the network when it is sent it would also be too big to be parsed from disk so what would be the point of saving the xml?

If you xml response is too large you should refactor the webservice to support paged data or find some other way to reduce the response size imho.

It's not true. If i can save the xml file on disk, i can read it depending on free VM space available. So, if data are huge, i can, for example, split it in multiple file and read and parse one mini-file time by time and then clear memory every time i finished to parse it, and go to second one doing the same. However i solved the problem modifying by myself HTTPtransportSE file by introducing a static boolean by which i can choose if to save directly on VM memory (default behaviour) or if to save on disk

Fair enough. Care to share that improvement with the rest of us as a patch or pull request?

I left how i implemented code here:

http://stackoverflow.com/questions/4941581/very-large-soap-response-android-out-of-memory-error/12732396#12732396

Look for kinghomer's response (it's me).

I think It would be feasible to implement this as an alternative storing the xml where the File is passed into the transport in the constructor or as a parameter with some sort of flag that triggers the saving of the xml file. I will take a pull request if you send one ;-)

I have implemented this in master now. Please try it and let me know if that works for you.

I think this issue is more deeper than just OOM raised because of huge response. Sometimes I caught OOM exceptions. But it looks very strange. For example, I request 10M response from server and all is OK. After that I KILL application and start it and request 10M again and so on. In this test case I will receive OOM exception after iteration 5 or more.

My be it should be interpreted as memory leak in Android?

I think problem is that memory is not cleaned as well after data is consumed. I put in HttpTransportSE class file a call to these functions:

arrayOfDataDownloaded = null; System.gc();

By this call i solved that problem. Btw, problem is always huge response. Every device dedicates a specific and equal amount of Memory for each application. For example, S3 dedicates 48Mb-Ram foreach App because has 1gb Ram memory. Another device that has 512Mb-Ram dedicates 24Mb. This fact cause why App doens't work on all devices. This is where i think problem is.

Good to see that this issue is closed already.

When can we expect the latest JAR? Tentative Date ?

Or Shall we download and compile the latest code?

Released with 3.0.0

Releasing now.

Hi guys. I tested new release and it works fine with file, but.... seems there is a problem in text format (this problem occurs only if i use call() method to save response on file too). For example, if WS response is an Xml String, in which open and close tag are rappresented by special characters like "<" and ">" or "<" and ">", occurs an XmlPullParser Exception. If WS response is simple text like "GUID", there is no error but happen this:

Example with classical call() method -> httpTransport.call(soapAction, Envelope). Response dump is:

GUID

Example with new call() method (i set header's List to null) -> httpTransport.call(soapAction, Envelope, null, File). Response dump is:

GUID ������������������������

As you can see, something is written after Envelope node is closed. This "something", instead, seems that's not written in file.

Can you file this as a separate new issue and maybe figure out what is going on and send a fix as pull request?

Problem is that i can't find source code. If i go here:

https://github.com/mosabua/ksoap2-android/tree/

i can't find java files. Directories seem empties

What are you talking about .. its all there.. e.g. https://github.com/mosabua/ksoap2-android/blob/master/ksoap2-base/src/main/java/org/ksoap2/SoapEnvelope.java

Sorry, i didn't see it. Too work turned me stupid
