[android-developers] Re: Saving form data to XML
To create new xml file on SD card I am using following code
String strFileName = Environment.getExternalStorageDirectory()+/ +
temp.xml;
try{
if(!lXmlfile.exists())
{
lXmlfile.createNewFile();
}
}catch(IOException e){
Log.e(IOException, e.toString());
return
null;
}
Above code giving me IO exception Permission denied. Although I have
added permission in AndroidManifest.xml
like:
uses-permission
android:name=android.permission.WRITE_EXTERNAL_STORAGE/
still , can not create file. where am I going wrong? how can I test
this on emulator (create file on which path?) .Pls help its urgent.
One more question: Is user defined content provider is the best way to
complete this requirement(saving and retrieving form data that also
contains image). Pls share.
Regards

[android-developers] Saving form data to XML
Hello ,
developing application with form having multiple fields, at the end
user need to submit the information.
On this event, all the data need to be stored in XML file.
thus XML write is required. plus when user asks for particular id then
the data filled by that id is also to be displayed thus XML read is
required.(search operation)
Following is the code I tried for generating sample xml.
/
FileOutputStream fileos = null;
try{
fileos=openFileOutput(newxml.xml,Context.MODE_PRIVATE);
Log.v(info,fileoutput open);
// fileos = new
FileOutputStream(newxmlfile);
}catch(FileNotFoundException e){
Log.e(FileNotFoundException, can't
create
FileOutputStream);
}
// create a XmlSerializer in order to write xml
data
XmlSerializer serializer = Xml.newSerializer();
try {
//we set the FileOutputStream as output
for the
serializer, using UTF-8 encoding
serializer.setOutput(fileos,
UTF-8);
//Write ?xml declaration with
encoding (if encoding not null)

text inside child3);
serializer.endTag(null,

serializer.endTag(null, root);
serializer.endDocument();
//write xml data into the
FileOutputStream
serializer.flush();
//finally we close the file
stream
fileos.close();
//TextView tv =
(TextView)this.findViewById(R.id.result);
//tv.setText(file has been
created on SD card);
Log.v(info,file has been
created on SD card);
return true;
} catch (Exception e) {
Log.e(Exception,error
occurred while creating xml file);
return false;
}
//
executed this with actual device but, no new xml file is created.
where to store this programatically created xml file?
On emulator if I want to test this application, where the xml file
will get stored?
Pls guide me whats going wrong?
Thanks.

[android-developers] multi page form
Hello , I am new to android paltform. How to navigate through multi page form application? how to handle next and back button click event? My point of confusion is that, form filling is single activity , then how to display multiple pages of the form and how to navigate back and forth from pages in that activity? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: multi page form
Thanks all for help. The intended from has multiple fields (around 25-30 fields) so it can not be fitted in single screen. As all agrees , user doesn't like to scroll , I want to divide fields into multiple pages (~5 fields per page) and navigate through them from user friendly perspective. I read about Intents , but Intents make call to other activity from currently running activity. Conceptually form filling is single activity only it need to be divided into pages, so here , is it appropriate to use intents ? Further , the information entered in all pages need to be stored (as a record , may be in xml file) at the end of form filling. what is proper way to approach this requirement, Pls share. Thanks in advance. On Sep 6, 9:24 pm, Logesh rajendren loges...@gmail.com wrote: my advice is to shrink your UI so that it fits into a single page. because Users dont like to use scrolls.
