Please do not construct filenames and Uri's by pasting together
strings.
The correct way to write this is:
Uri.fromFile(new
File(Environment.getExternalStorageDirectory(), "zibra.txt"))
or to make it a bit more clear:
File dirFile = Environment.getExternalStorageDirectory();
File zibraFile = new File(dir, "zibra.txt");
Uri zibraUri = Uri.fromFile(zibraFile);
Or, if you need a URI instead of a Uri:
URI zibraURI = zibraFile.toURI();
There's also File.toURL().
HOWEVER, the documentation for Intent.EXTRA_STREAM says you need a
content: URI (I presume that should be Uri?), not a file: one. If you
want to give the other application access to your app's data, create a
content provider. Applications don't have access to files belonging to
other applications. A content provider (and content: URI) give your
application control over what information to make available, and to
whom.
