I replaced my original sdcard with a sandisk 16gb card. Everything went well until I started getting these blasted read on errors. Earlymon suggested a fix from another board but I don't have a stand alone card reader so I couldn't do it that way.
I was wondering if I just backed up all my stuff from my sdcard to my iMac and then just reformatted my sdcard via the phone, would that solve my problems?
I have the file in sdcard: sample.xml I want to read it, so I dont know some code to connect to sdcard in android.

I have an application that can read and write txt files to the phones sdcard. By using this code for reading files:
@Override protected void onListItemClick(ListView l, View v, int position, long id) { super.onListItemClick(l, v, position, id); mFileNameOpen = files.get(position);
String st = null; mVector.clear();
notepad.mNewEmpty = false; try { File f = new File(Environment.getExternalStorageDirectory()+"/ notepad/"+mFileNameOpen); FileInputStream fileIS = new FileInputStream(f);
BufferedReader in = new BufferedReader(new InputStreamReader(fileIS));
do { st = in.readLine();
mVector.add(st);
}while(st!=null); in.close(); ...
} catch (FileNotFoundException e) { e.printStackTrace();
} catch (IOException e) e.printStackTrace();
and this to write them:
try { File root = Environment.getExternalStorageDirectory();
File fileCheck = new File(root, "/notepad/" + fileNameSave + saveExtension);
boolean exists = fileCheck.exists();
if (!exists) { if (root.canWrite()) { File textFile = new File(root, "/notepad/" + fileNameSave + saveExtension);
FileWriter textWriter = new FileWriter(textFile);
BufferedWriter out = new BufferedWriter(textWriter);
out.write(SAVEAS); out.close(); written = true;
} else { written = false; else { written = true; showMaybe = 1; showDialog(DIALOG_SAVE_EXISTS);
catch (IOException e) {Log.v(getString(R.string.app_name), e.getMessage());
This has been working fine on my Tattoo and all the emulators I've tried this on. But it does not seem to be working on moto droid. Is there something different to consider with moto droid? Or have I missed something in the manifest maybe?

I've got an AVD setup with an SD card, but I wanted to specify a different SD card image by setting a -sdcard option in Eclipse under Preferences -> Android -> Launch (I fill in "-sdcard C:sdcards sdcard96M.img" without the double quotes). But it seems no matter what I do, I always get the SD card that was created with the AVD. From the command line, the following works: emulator -avd myAVD -sdcard C:sdcardssdcard96M.img Do I need to use the command line instead of Eclipse to run this way?

i want to move specific app data(/data/data/klb.android.lovelive and subdirectories) to sd-ext partition(/data/sdext2/)
Directory Bind or FolderMount are moving data in /mnt/sdcard/Android/data and obb files to external sdcard, which for devices with internal storage.
i'm not trying to move obb files or data in sdcard.
is there any way to move one app data to sd-ext? i don't want to move hole /data/data to sd-ext(data2ext)
I got this 16G sdcard that from one day to another it stopped being recognized saying "blank card or has unsupported file system"
Besides the data, I had some applications installed on it.
I did tried to recover with a software, but even the software only can recognize space is occupied, but can't see it.
It appears as unformatted BUT, I know that the data is still there because the CWM manages to browse files if I get into the menu "install zip from /sdcard1", but it can't see anything if I try a "restore from sdcard1"...
So I have an ubuntu build and I'd like to try to repair the "masterboot" .
I never did this before so I don't really know what I need, SDCard is 32 GB class 10.
When I plug my phone from CWM and enable the mount the SDcard on usb I got this error message :
Error mounting: mount: /dev/sdb1: can't read superblock
Here is the result of the "fdisk -l" command :
Code:
Disk /dev/sdb: 32.0 GB, 32018268160 bytes
32 heads, 63 sectors/track, 31019 cylinders, total 62535680 sectors
Units = sectors of 1 * 512 = 512 bytes

/dev/sdb1 2048 62535679 31266816 b W95 FAT32
Which actually looks weird, I thought that my sdcard were ext4 formated, well but I am not 100% sure about that...
Here the result of the command "fsck -y /dev/sdb1"
Code:
fsck from util-linux 2.20.1

FAT32 root dir starts with a bad cluster!
I have a Mocordroid with scp6820a cpu rooted
First some objections:
1- The sdcard is used in vfat filesystem, move simplely /data folder to sdcard will be cause some problems
2- Copy /data to /mnt/sdcard/data will not work completly because we got some error of permission
Code:
adb shell
Code:
cp -r /data /mnt/sdcard
cp: can't create directory '/mnt/sdcard/data/misc/bluetoothd/FA:2B:B7:4E:90:59': Invalid argument
cp: can't create symlink '/mnt/sdcard/data/data/org.mariotaku.twidere/lib': Operation not permitted

So first thing i change size of sdcard, decreasing the partition size, and add a second partition with 3 Gbytes using ext2. To do this
Unmount the sdcard in settings>storage>unmount sdcard. I need discover where is the partitions
Code:
fdisk /dev/block/mmcblk0
[Code] ....
For secure i reboot device, and umount card again. So format the second partition
Code:
mke2fs -t ext2 -m0 -b4096 /dev/block/mmcblk0p2
And reboot again. This was hopeful action that it would recognize the card. But not ...
Code:
# mkdir /mnt/sdext
mount -t ext2 /dev/block/mmcblk0p2 /mnt/sdext
mount: No such device
mount -t ext2 /dev/block/vold/179:2 /mnt/sdext
mount: No such device

Is there anyway to read data from an attachment through the USB port on an Android device? In particular, an EKG. Most the work can be done by the hardware of the device to simplify the output to a single number, a voltage reading. If its not possible, what about modifying an accessory that can already communicate with an android device? Thinking of devices that attach to android phones, what about sending the data as an audio signal to be read as the microphone from a headset and then analyzing the audio signal to convert it to a number that can be used to display a value. how to make this work?
