Android :: File Copied To SD Card - Contents Not Matching With Original Source
Feb 4, 2009
We have ported android to our hardware. I am facing some issues related to sdcard. Here is the test scenario and issues:
First issue :
1. On hardware, insert the card and copy a file to sdcard using dd command.
2. Remove the card from hardware.
3. Do ls /sdcard. It shows the file present in sdcard. It seems unmount of sdcard device is not happening.
Second issue:
1. Copy a file to sdcard using dd command.
2. Remove the sdcard and check the content of the sdcard from PC. File is not visible.
3. Copy file to sdcard again and then check the content of sdcard from PC. File size is zero bytes.
4. Restart the hardware and copy the file again. File is visible when checked from PC.
Third issue:
1. The content of copied file are not matching with the original source file.

1. I have a problem with my files. It became corrupted (but not all of them) when copied from internal SD to external SD. There isn't any problem with my old 2GB SD card.
I'm using ES File Explorer to copy them to the external SD Card. Yes, the phone supports up to 32GB microSD card.
Details:
Samsung Galaxy Pocket GT-S5300
Stock 2.3.6 firmware DXLK1 rooted.
Sandisk 32GB microSD Class 4

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.

I am developing an application that needs to access data on the sd card. When I run on my development device (an odroid with Android 2.1) I have root access and can construct the path using:
CODE:..........................
However, when I install this on a phone (2.1) where I do not have root access I get files == null. I assume this is because I do not have the right permissions to read the data from the sd card. I also get files == null when just trying to list files on /sdcard. So the same applies without my constructed path.
Also, this app is not intended to be distributed through the app store and is needs to use data copied separately to the sd card so this is a real use-case. It is too much data to put in res/raw (I have tried, it did not work).
I have also tried adding: <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
To the manifest, even though I only want to read the sd card, but it did not help. I have not found a permission type for reading the storage.

OK new owner of an LG Ally. I want to get my photos and videos off my old sd card copied to my new, much larger sd card. I wont read in my pc unless I format it and I don't want to do that.
It's no doubt easy but it's making me crazy. System is a whole lot different than Im used to.

I guess many people already read this article:
Using your own SQLite database in Android applications: http://www.reigndesign.com/blog/using-your-own-sqlite-database-in-android-applications/comment-page-2/#comment-12368
However it's keep bringing IOException at
CODE:.............
I'am trying to use a large DB file. It's as big as >8MB. I built it using sqlite3 in Mac OS X, inserted UTF-8 encoded strings (for I am using Korean), added android_meta table with ko_KR as locale, as instructed above.
However, When I debug, it keeps showing IOException at
CODE:..............
I suspect it's caused by trying to read a big file. If not, I have no clue why.
I tested the same code using much smaller text file, and it worked fine.
Can anyone help me out on this? I've searched many places, but no place gave me the clear answer, or good solution. Good meaning efficient or easy.
I will try use BufferedInput(Output)Stream, but if the simpler one cannot work, I don't think this will work either.
Can anyone explain the fundamental limits in file input/output in Android, and the right way around it, possibly?

I have created a app that displays all the content from res/raw folder. I need that when I click on .doc file it should open and I can view its content. I have ThinkFree.
Enter code here:
public class FileList extends ListActivity {
public static final Field[] fields = R.raw.class.getFields();
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setListAdapter(new ArrayAdapter<Field>(this, R.layout.row, R.id.weekofday, fields));
} @Override
protected void onListItemClick(ListView l, View v, int position, long id) {
// TODO Auto-generated method stub
//super.onListItemClick(l, v, position, id);
String selection = l.getItemAtPosition(position).toString();
Toast.makeText(this, selection, Toast.LENGTH_SHORT).show();
Intent i = new Intent();
i.setAction(android.content.Intent.ACTION_VIEW);
startActivity(i);
} }

How do I save the contents of an array to a file and then read it again later? I have a small amount of data that will need to be stored and since I have no idea where to start on using a SQLite database, I think this will work a lot better.

Does this mean that an app has access to internal AND sd card contents, or just the contents of the sd card?

I am receiving the battery and SD card to go along with the HTC Droid Incredible 2 I got today. He said to hook up my phone to the computer (not sure which setting to choose, PC Mode, etc) and then copy the SD card stuff to the computer. Then I'm supposed to transfer that to the new 16gb card I'm getting.

All is fine with the new rom except that my SD card contents aren't visible in the file manager. But if I connect it to the PC it shows up just fine.

Look, one of the first things I have made with my new HTC Tattoo has been formatting the SD card. As soon as I realized what I had done, I turned off the phone, extracted the card, and using testdisk, I recovered its contents. They were:
Some example background images.
Some example music, with cover images
A pdf file, the instruction manual of the machine.
An executable, the sync program.
A large lot of .txt and .f files. Some of them contain image orientation data. The rest contain code. For example:

hey folks. I started out with a nice nippy class6 8GB card thinking speed was better than space and using Spotify for tunes I'd not have many mp3 locally. Now I need more space and want to switch to a 16GB card.My question: can I just copy everything off of my 8GB onto my new 16GB when it arrives? be great not having to download 5GB of Spotify cache all over again.

Anybody else notice that the SD cards are write protected? If I take out my card and put it in a card reader on my laptop, I can add stuff to the card, but I can't delete anything. If I put it back in the phone and mount the sd card, I can edit the card how I want. weird?

Is there a way to check the contents of the SD card in the Incredible without connecting to a computer? All I can find is how big the SD card is and how much room is left on the card. But like I said, I cant find a way to see what files are on it.

I am trying to reverse engineer an existing android app and understand how a particular UI is constructed. I've found that I can rename the apk to zip and view some of the compiled source. The res/layout directory is populated with all the xml files that define the UI, but while they do have the xml extension, they are not in XML format. Is there anyway to convert these files back to text based markup?

I have a Google I/O phone which came with the original 2 GB micro SD card. I would like to get a larger capacity card and while shopping for it I noticed that some of them are just micro SD and some are micro SDHC. The user manual I downloaded from the HTC website has not specification on the type of SD card that are supported. Can someone tell me if the phone I have works with both types or can I only use micro SD card?
