Android :: XML Parsing Slow - Cache

Aug 16, 2010

I have seen that xml parsing is very slow. Using sax would be better, but benchmark show that sax work only 30% faster as dom. Is right? Is faster if I construct a "DOM" using sax?

To reduce time i like to cache xml file. Caching it as xml is not a good idea because the parsing time is there again the secondo time.

Should I use sqllite? Is faster? Is an idea to use an ObjectOutputStream? Can I put in asset a file maked by ObjectOutputStream or the serialized objects can be different in different mobile hardware?

General :: Disable Moving Of System Dalvik Cache To /cache?

Aug 16, 2012

In cm roms, dalvik cache of system apps are generated in /cache but those data/apps are generated in /data. Is there any way to disable this behaviour? Cache partition in our phones is too small. In AOSP and AOKP and stock roms, dalvik cache is always generated in /data no matter whether its a system app. any way to achieve this in cm roms?

Android :: Android - Image Cache Stategy And Memory Cache Size

Jun 21, 2010

I'm implementing an image cache system for caching downloaded image.

My strategy is based upon two-level cache:
Memory-level and disk-level.

My class is very similar to the class used in the droidfu project

My downloaded images are put into an hashmap and the Bitmap objet is wrapped inside a SoftRererence object.

Also every image is saved permanently to the disk.
If a requested image is not found into the Hashmap<String,SoftReference<Bitmap>> it will be searched on the disk, readed, and then pushed back into the hashmap. Otherwise the image will be downloaded from the network.

Since I store the images into the phisical device momery, I have added a check for preserve the device space and stay under a 1M of occupied space:

CODE:.................

This method is called sometime afte a disk writing:

CODE:..............

What I'd like to add is the same check on the HashMap size to prevent it will grow too much. Something like this:

CODE:.....................

My question is:
What could be a right MAX_MEMORY_SIZE value? Also, Is it a good approach? A good answer also could be: "Don't do it! SoftReference is already enough"

Android :: Parsing XML From Net Using SAX

Apr 8, 2009

I really have a problem: When I want to parse this XML file:

XML file:
<marketexport> <createtime_timestamp>1236801648</createtime_timestamp> <createtime_date>11.03.09 - 21:00</createtime_date> <ressources> <ressource> <name>Energie</name> <price>14</price> <number>11967033</number> </ressource> </ressources> <race> <race_name>Nova Federation</race_name> <military_units> <unit> <name>NoF Marine</name> <price>1200</price> <number>845</number> </unit> </military_units> <spy_units> <unit> <name>Thief</name> <price>0</price> <number>0</number> </unit> <unit> <unit> <name>Agent</name> <price>0</price> <number>0</number> </unit> </spy_units> </race> </marketexport>

ExampleHandler:

public void startElement(String namespaceURI, String localName,
String qName, Attributes atts) throws SAXException {
if (localName.equals("marktexport")) { this.in_marktexport = true;
} if (localName.equals("ressources")) { this.in_ressources = true;

} if (localName.equals("unit")) { this.in_unit = true;
} if (localName.equals("name")) { this.in_name = true;
} if (localName.equals("price")) { this.in_price = true;
} if (localName.equals("number")) { this.in_number = true;
} }
public void endElement(String namespaceURI, String localName, String qName)
throws SAXException { if (localName.equals("marktexport")) { this.in_marktexport = false;
} if (localName.equals("ressources")) { this.in_ressources = false;
} if (localName.equals("ressource")) { this.in_ressource = false;
} if (localName.equals("name")) { this.in_name = false;
} if (localName.equals("price")) { this.in_price = false;
} if (localName.equals("number")) { this.in_number = false;
} if (localName.equals("race")) { this.in_race = false;
} if (localName.equals("race_name")) { this.in_race_name = false;
} if (localName.equals("military_units")) { this.in_military_units = false;
} if (localName.equals("unit")) { this.in_unit = false;
} } public void characters(char ch[], int start, int length) { if(this.in_race_name){
myParsedExampleDataSet.setrace(new String(ch, start, length));
} if(this.in_name){ myParsedExampleDataSet.setname(new String(ch, start, length));
} if(this.in_price){ myParsedExampleDataSet.setprice(new String(ch, start, length));
} if(this.in_number){ myParsedExampleDataSet.setnumber(new String(ch, start, length));
} }
ParsedExampleDataSet:
public void setprice(String price){ this.price = price;
} public void setname(String name) { this.name = name;
} public void setnumber(String number) { this.number = number;
} public void setrace(String race) { this.race = race;
} //Getter public String getnumber() { return number;
} public String getprice() { return price;
} public String getname() { return name;
} public String getrace() { return race;
} //.toString() public String toString() {
result = getrace()+"
Name: "+getname()+"
Preis: "+getprice() +"
Number: "+getnumber();
return result;
}
I Only get:
Nova Federation Name: Agent Preis: 0 Anzahl: 0
So I want to get: Nova Federation Name: NoF Marine Preis: 1200 Number: 845

Android :: XML Parsing In Java

Jul 11, 2010

The API I need to work with does not support xpath, which is a bit of a headache! The xml I want to parse is as a String. My questions: Is there a Java equivalent of "simplexml_load_string", where it makes the string into an xml document for parsing? Which is better for parsing, SAX or DOM? I need to get a couple of values out of the XML and the structure isn't that deep. [3 levels]

Android :: IOException On SAX Parsing

Apr 25, 2009

I'm trying to parse an XML file from res/raw or assets/ using the javax SAX parser. When the file is too large (~ 1MB), the parse(...) method throws an IOException without further information, such as message or inner exception. When I reduce file size to e. g. 600 kB, it's working again.

Android :: Use Parsing HTML / No XSLT?

Aug 27, 2010

In need in my application to fetch remote HTML document and parse some parts out of it. As I don't want to play with string parsing, which would be really lots of work, I thought about using XSLT, which would let me build small XML document out of HTML and then read it easy.Seems there is no XSLT support in Android? What other ways I could parse HTML without parsing content as simple string directly?

Android :: Maximum Size When Parsing XML With DOM

Nov 15, 2010

Currently I'm implementing a REST client which shall parse the XML response messages. It is intended, later, to be running on an Android device. Thus, memory and processing speed is quite an issue. However there will be only one XML response at a time so processing or holding multiple XML documents at a time is not an issue.

As fas as I understood there are three ways of parsing XML with the Android SDK:

SAX
XmlPullParser
DOM

Reading about these different parsing methods I got that SAX is recommended for large XML files as it won't hold the complete tree in memory like DOM.

However, I'm asking myself what is large in terms of kilobytes, megabytes, ...? Is there a practical size up to which it does not really matter whether using SAX or DOM?

Android :: Abort SAX Parsing Mid Document?

Apr 5, 2010

I'm parsing a very simple XML schema with a SAX parser in Android. An example file would be
<Lists>
<List name="foo">
<Note title="note 1" .../>
<Note title="note 2" .../>
</List>
<List name="bar">
<Note title="note 3" .../>
</List>
</Lists> the represents more note data as attributes that aren't important to question.I use a SAX parser to parse the document and only implement the startElement and 'endElement' methods of the HandlerBase to handle Note and List nodes.However, In some cases the files can be very large and take some time to process. I'd like to be able to abort the parsing process at any time (i.e. user presses cancel button).The best way I've come up with is to throw an exception from my startElement method when certain conditions are met (i.e. boolean stopParsing is true).Is there a better way to do this?I've always used DOM style parsers, so I don't fully understand the SAX parser.One final note, I'm running this on Android, so I will have the Parser running on a worker thread to keep the UI responsive. If you know how I can kill the thread safely while the parser is running that would answer my question as well.
