Question

I have come across an issue that is driving me nuts xD … (Firstly: Hello everyone! For some reason I cant prepend the “Hello everyone” at the beginning of the post in edits oO…)

The use-case is as follows: I have an xml file stored in my project’s raw folder. The xml file look something like this:

<myxml ....>Some text<innerelement ... /></myxml>

I know there is a folder called xml but what I need is a string – not an XmlResourceParser (which you get when calling context.getResources().getXml(id)).

Now, what I do to load this raw xml file is:

context.getResources().openRawResource(R.raw.myfile)

This returns me an InputStream, which I then try to convert to a String using the following code:

try {
   byte[] buffer = new byte[stream.available()];
   stream.read(buffer);
   stream.close();
   return new String(buffer);
} catch (IOException e) {
   // Error handling
}

If I now print the resulting String to logcat, all I get is a bunch of squares, spread across a few lines.

So I guess I must be missing something there … I tried a few ways of converting this input stream to String already and all of them ended up with the same result (see image above) …

Thanks in advance & best regards,

UPDATE 12.11.2011

I tried saving the xml file in the raw folder using the extension .txt instead of .xml. Now the conversion fails with an OutOfMemory exception oO. I tried different way to convert the data using suggestions from this thread – all resulting in a OutOfMemoryException:

Answer 1

I put this code in onCreate(...). It can show the string in the xml file.

InputStream stream = getResources().openRawResource(R.raw.data);
try {
        byte[] buffer = new byte[stream.available()];
        stream.read(buffer);
        stream.close();
        Log.i("xml", new String(buffer));
} catch (IOException e) {
    // Error handling
}
