Re: [android-developers] Re: Write storage on Samsung Galaxy Tab 7.7

I think you just need to stop calling the SD Card and call it "External storage" or something.  If it's not on the SD card, why do you care?  Presumably, it's accessible if the device is connected to a PC via the USB, correct?

If you must write to a removable storage, I don't think you can guarantee that.  But once again, and I have no idea what kind of app you have, why do you care?

That's absolutely not true -- my app, on a Galaxy Nexus, can write to the folder pointed to by:

Environment.getExternalStorageDirectory().getAbsolutePath()

I have the WRITE_EXTERNAL_STORAGE  set.  I use it for backup and had nobody complained yet.

The Galaxy Nexus does not have *removable storage*, as far as I know, so that is not a counter example. 

And I have NEVER had trouble writing to Environment.getExternalStorageDirectory()

But in many devices, the getExternalStorageDirectory() returns a directory that is internal storage.

The same devices sometimes have another, external storage slot with the following characteristics:

• There is NO call equivalent to getExternalStorageDirectory() to find out what the path is
  
• The users often don't know what the path to it is.
• I don't know what the path to it is.
  
• The manufacturers don't publish what those paths are.
  
• If, by some miracle, the user finds out what that path is, my app checks that folders and finds that it is read only, at least for my app.
  
• I do not know why it is read only, but I believe the manufacturer, or perhaps the ICS platform, has made the decision that only certain apps can use it.
  

I would really like to know what it is going on, besides manufacturers making developers look like idiots. I only have a budget for a small number of devices, so it is really hard for me to see the general trend.
