Android :: Sd Card File Write
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:..................

Android :: Write XML Document To File
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.

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.

Android :: Write Contents Of Custom View To Large Image File On SD Card
I have a class that extends View. I override the onDraw method and allow the user to draw on the screen. I am at the point where I want to save this view as an image. I Can use buildDrawingCache and getDrawingCache to create a bitmap that I can write to the SD card. However, the image is not good quality at a large size, it has jagged edges. Since I have a View and I use Paths I can transform all by drawing to a bigger size. I just don't know how to make the Canvas bigger so when I call getDrawingCache it doesn't crop all the paths I am just transformed. What is happening is I transform all my paths but when I write the Bitmap to file I am only getting the "viewport" of the actual screen size. I want something much bigger.

Android :: Cannot Write To SD Card
Sorry for the ambiguous title but I'm doing the following to write a simple string to a file:

try {
File root = Environment.getExternalStorageDirectory();
if (root.canWrite()){
System.out.println("Can write.");
File def_file = new File(root, "default.txt");
FileWriter fw = new FileWriter(def_file);
BufferedWriter out = new BufferedWriter(fw);
String defbuf = "default";
out.write(defbuf);
out.flush();
out.close();
}
else
System.out.println("Can't write.");
}catch (IOException e) {
e.printStackTrace();
}

But root.canWrite() seems to be returning false everytime. I am not running this off of an emulator, I have my android Eris plugged into my computer via USB and running the app off of my phone via Eclipse. Is there a way of giving my app permission so this doesn't happen? Also, this code seems to be create the file default.txt but what if it already exists, will it ignore the creation and just open it to write or do I have to catch something like FileAlreadyExists(if such an exception exists) which then just opens it and writes?

The predicament : all CSV examples are in reference to contacts, and the file read/write posts (the ones that I need) make the assumption that I am not a beginner and most don't even post any code leaving me nothing to learn on.

The hopeful solution : a link to a solid example of simply how to write to a CSV with my own custom fields and values, and how to read a CSV and load said values.
