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.

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,...

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
