Problem saving on sdcard of Nexus S

I cannot save a text file o开发者_JAVA技巧n a Nexus S. State is mounted, path is ok (/sdcard/filename), there is a permission in my manifest file for extenal storage.

The program gives an IOException on this line:

File file = new File(path, fileName + ".txt");

I have no idea how to detect the problem, especially if it works fine on a Galaxy Mini. I have been struggling saving a txt file on Samsung Galaxy for some time, but made it work by removing a line from the manifest file defining the min sdk version. It did not accept any min sdk version in fact, so I removed it altogether for now...

Can anyone help?

String path= Environment.getExternalStorageDirectory().toString()+"/";
File file = new File(path+fileName + ".txt");

try it out

As described in the docs, you should first check that external media is mounted:

if (Environment.MEDIA_MOUNTED.equals(Environment.getExternalStorageState())) 

and then use it via Environment.getExternalStorageDirectory().

If you plan to save publicly accessed files (pictures, videos, music, etc..) then use Environment. getExternalStoragePublicDirectory(..) with appropriate argument.
