I want to create a file on the SD-Card and later save a CSV file in it.

I would like to write a file to the SD card from my application, but the following code throws an IOException when debugged on a T-Mobile G1:
String p = Environment.getExternalStorageDirectory() + "/log.txt"; File recfile = new File(p); recfile.createNewFile();
The last line throws an IOException with detailMessage = "Cannot create: /sdcard/log.txt". The MOUNT_UNMOUNT_FILESYSTEMS permission is set in the manifest. And yes, I really do want to write to the SD card; I don't want to use the logging features Android includes for this particular application. The Android documentation does not seem to give any specifics on how one might write files to removable storage in "Data Storage" under "Framework Topics". What am I doing wrong, or where can I read more about this topic?
In my MediaPlayer application for streaming Video i am using the following code File temp = File.createTempFile("mediaplayertmp", "dat"); while running it throws exceptions like
Parent directory of file in not
writable:/sdcard/
mediaplayertmp43912.dat
I dont how to handle this problem, and i want to know that when we execute that code means where the file will be created.
1. It contain's the native binary with it. Then it will llod that native binary to AFS. 2. Then it should call or execute that native binary. But when I do that one. The native binary is working fine. But the problem cmoes out here. The function of the native binary is to read the file in the AFS and to copy it to another location.
But when I do the above steps. The native binary has been successfully loading to the AFS. After that when I try to execute the native binary. The file is get created with 0 size. The file permissions looks like below.

How can I create a XML file that has identation or, at least, line breaks between each tag? I'm using class XMLSerializer (available in Android) to handle the XML creation.
XMLSerializer serializer = new XMLSerializer();
StringWriter writer = new StringWriter();
serializer.setOutput(writer);
String xmlFileContents = writer.toString();
Then I use the contents of xmlFileContents to create a file, using a BufferedWriter. The file is written, but the XML is not idented, and would like it to be.

I was wondering if it were possible to dynamically create an XML layout file to be displayed to the user. The idea would be to be able to retrieve a layout file from a central server, which could display this dynamic, server driven GUI.

I copied song.mp3 to my project's assets directory and wrote this code:
private MediaPlayer mp;
Uri uri = Uri.parse("file:///android_asset/song.mp3");
mp=MediaPlayer.create(this, uri);
After running the create statement, the variable mp is null.
not sure how to inflate this from my layout file: MyView v = LayoutInflater.from(this).inflate(R.layout.myview, null); the inflater of course does not know what 'MyView' type is, and returns only View. What's a good way to reconcile this?
View 1 Replies View RelatedI'm currently only testing things in an emulator due to not having an Android device as of yet. I'm honestly holding out for some of the new 1 Ghz machines to come out and do some comparisons. Anyway, I would imagine one would easily be able to make whatever folders they choose on an sd card, but on the emulated one, I can only seem to push entire folder contents or single files to the root. The adb help doesn't appear to have a command to make a folder. Is this not possible, or am I just missing something?

At the moment I've this rooted phone running ICS, an SD card, an SD to USB reader and a netbook that once ran windows 7 until an hour ago. Oh and no working computer access for a few days.
I've installed a couple of versions of linux on PC's in the past, mainly as quick fixes between windows installations as I've proved myself too much of a novice to use it full time, so I know it can be done from an SD card easily enough should you be able to make one bootable with linux installed.
As I've only got this phone for a few days, would it be possible to do the above directly from this device?
When I make a new project the .java file is not generated. I can run the project, but it does not run in the emulator or anything. It did use to work before then it stop working. I tried deleting the folder and all project files. After that I reinstalled everything but I am still having problems.

I tried to make a goldcard for rooting my HTC Hero (Three UK with latest ROM) over the weekend, but had no luck - it seems the memory card I own (an 8gb Kingston card from ebay, so may be a fake) doesn't work.
Can anyone recommend a memory card brand & size that will *definitely* work for creating a goldcard?

How come this is the only file manager on the market (that I've found... I went through quite a few) that can open an HTML file from your SD card? I was a loyal user of Estrogen until I found that it couldn't.
