Android :: Write An XML File To A Url?
Nov 21, 2010
I am trying to write an XML file to a url e.g. http://myIPAddress/myFolder/myFile.xml
I am using an Apache2 server for my tests on Ubuntu 10.10
Output line example (ignore apostrophe):
<'myEntity id="1" name="me" />
Also, i want to able to reopen the connection anytime and add lines to the end of the file.
I'd post my attempt here for correction but it's a sad one.
I am trying OutputStreamWriter with URLConnection, please correct me if i should be using a different approach.

I would like to know how to write to file. I have tried using OutPutStream out = new FileOutPutStream(fileName); out.write(byte [], 0, length);This way always returns Parent directory or File is not writable.I have also used openFileOutPut(fileName, MODE_PRIVATE) method but this method works properly if it is called from the same class which has extended Activity and I am writing to the file in different class and that too in different thread.I have tried to get the Application Context through getApplciationContext and call openFileOutPut method but still theres something wrong that I am doing.So please can someone suggest me a proper way to write to a file.

I'm trying to write a file from an Http post reply to a file on the sdcard. Everything works fine until the byte array of data is retrieved. I've tried setting WRITE_EXTERNAL_STORAGE permission in the manifest and tried many different combinations of tutorials I found on the net. How my app writes file is by using a thread. Specifically, a thread is invoked from another thread when a file has to be written, so giving an activity object didn't work even though I tried it. The app has come a long way and I cannot change how the app is currently written. CODE:..................

This should be trivial, but for whatever reason I can't find any easy way to do this. Coming from C# where this is a 1 line call, I don't understand why Java makes this so complicated, and on top of that android leaves even that out of its libraries. Anyway all I want to do is write an
org.w3c.dom.Document
that I have populated to a xml file. It should be as easy as opening a stream and writing document.toString(). But that doesn't work. My hope is I'm just missing something.

I wrote a file to the sdcard, but it failed as follow:String sdcardFIle = "/sdcard/xxx.txt" FileOutputStream fos = openFileOutput (sdcardFile, Context. MODE_ WORLD_ WRITABLE ) ; openFileOutput failed, because fIle "/sdcard/xxx.txt" contains a path seperator. It is so strange. Is there another way to handle the situation?

Today, i tried to read and write file on the android. but it seems that file write mode is only provided for SD card? most of article is asked about SD card written. Is there no way to save data internal side?So when i install the application to real device. then its application installed in SD card or internal space? because we have make it log file from our application for everytime while application run.So, how do we write the file to SD card and specified the absolute path where we saved? to load this file.

I'm trying to create a file on the sd card.but that throws a FileNotFoundException. Isn't OutputStream supposed to create the file, if not found on disk? I'm looking to write image data there.This is on a 1.6 emulator. I have an SD card installed, I'm looking at the sdcard folder through DDMS, so it's there.

Might sound crazy, but it's what I need to do. I want to take a Bitmap object and use the XMLPullParser/XmlSerializer to write this to a flat file. Obviously I will need to read the XML tag back into a Bitmap object.So somehow I have to turn my Bitmap into a String and then turn that String back into a Bitmap. I will do some searches on Base64 to see if I get any good examples.

I need to write a ContentProvider to provide a dynamically generated audio stream to be playable by MediaPlayer. That is MediaPlayer will use ContentResolver.openInputStream() to play it. I have read a lot of discussions about this problem but no one had a solution yet. The most recent one was in January 2010: http://groups.google.com/group/android-developers/browse_thread/threa.

I found out that you can use something like this to create a file:
CODE:............
When running the above code I get an IllegalArgumentException stating:
CODE:......
And Im guessing the "/" is not appreciated. I wanted the "/" since I need to write the file to the root directory of the device, as stated in the API in trying to follow:
CODE:.........
Question is: how do I place a file in the root-directory? I have been looking around for an answer, but havent found one yet.

Is there a right associated with write/read access to the sd card that needs to be set in the manifest.xml file? I'm currently trying to write to the sd card using a standard FileOutputStream here:
FileOutputStream out = new FileOutputStream("/ sdcard/images/"+imageName);
bmp.compress(Bitmap.CompressFormat.JPEG, 90, out);
But it doesn't seem to be working. It just says the location isn't found, which can happen if there are no permissions to read/write to the location.
