Very large SOAP response - Android- out of memory error -

i have application need download large amount of data via soap call webservice application when first run. response sent function converts xml , stores data in db file.

the data more 16mb in size , have java.lang.outofmemoryerror everytime.

modifying webservice give out smaller amounts of data not option.

is there way able download large data? inputstream perhaps?

this code

public protocol[] getprotocols() {      string method_name = "getprotocols";     string soap_action = "urn:protocolpedia#getprotocols";     log.d("service", "getprotocols");     soapobject response = invokemethod(method_name, soap_action);     return retrieveprotocolsfromsoap(response); }  private soapobject invokemethod(string methodname, string soapaction) {     log.d(tag, "invokemethod");     soapobject request = getsoapobject(methodname);     soapserializationenvelope envelope = getenvelope(request);     return makecall(envelope, methodname, soapaction);  } 

can suggest should done in case?

thanks , regards mukul

two strategies solve problem:

1. save soap xml stream directly disk download it. don't store in memory.
2. parse using sax-style parser, don't load whole dom in memory, rather parse in chunks.

depending on kind of xml handling, using sax parsers harder in code; have keep track of many things yourself, , won't able "jump" section section of dom tree. memory consumption way lower.

take note, however, many "high-level" network communication libraries load whole xml dom in memory, might case here. have create , manage http connection yourself, , manually parse result.
