My new HTC desire is unable to read or write to my 8GB SD card which was previously inside my HTC HD touch.
Why is this? I've swapped the SD cards around - i.e. the 4 GB SD card which it came shipped with is now inside my HTC HD touch It doesnt have a problem reading or writingto the 4 GB SD card that it came shipped with. I would prefer not to have to format the card

I did a backup using Titanium Backup and Go Backup and after wiping my Motorola Defy, tried to restore apps, contacts etc. The problems I encountered were:
1) Go Backup can't recognize backup directory on SD card for some reason.
2) Can't move apps to SD. An error occurs: "Move Application: Failed to move application. There is not enough storage left." Needless to say, I have more than enough storage.
This is was I encountered by far, although I believe these are just a small part of the symptoms for a single problem.
Maybe its because there are no permissions, or moving apps is impossible because of an existing app files on the SD card.
What is the actual cause for this? Or is there a tool to fix the permissions on the Defy?
There are a lot of different classes that can be used in various ways to read/write to files in Android. For example, you can make use of java.nio.ByteBuffer, FileOutputStream and BufferedOutputStream. Are there any general guidelines for what to use to read/write quickly to the SD card? For example, BufferedOutputStream seems as if it should make things faster but I'm unsure the buffer size should be set for. Specifically, I want to read/write byte arrays that are ~1Mb in size as quickly as I can.

View 4 Replies View RelatedIs there a right associated with write/read access to the sd card that needs to be set in the manifest.xml file? I'm currently trying to write to the sd card using a standard FileOutputStream here:
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.

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.
