startActivityForResult(intent, OPEN_REQUEST_CODE);

</pre>

When executed, the above code will cause the picker user interface to be displayed, allowing the user to browse and select any files hosted by available document providers. Once a file has been selected by the user, a reference to that file will be provided to the application in the form of a Uri object. The application can then open the file using the openFileDescriptor(Uri, String) method. There is some risk, however, that not all files listed by a document provider can be opened in this way. The exclusion of such files within the picker can be achieved by modifying the intent using the CATEGORY_OPENABLE option. For example:

}

</pre>

The above method verifies that the intent was successful, checks that the request code matches that for a file open request and then extracts the Uri from the intent data. The Uri can then be used to read the content of the file.

}

</pre>

First, the file descriptor is extracted from the Uri, this time requesting write permission to the target file. The file descriptor is subsequently used to obtain a reference to the file’s output stream. The content (in this example some text) is then written to the output stream before the file descriptor and output stream are closed.
