问题
I want store a file audio in my personal content provider. i save record:
Uri uri = getContentResolver().insert(CONTENT_URI, values); OutputStream os = getContentResolver().openOutputStream(uri);
but getContentResolver().openOutputStream(uri); throws:
10-13 19:44:53.903: ERROR/TAB(5679): No files supported by provider at content://com.memento.data.provider.MementoProvider/audionotes/6 10-13 19:44:53.903: ERROR/TAB(5679): java.io.FileNotFoundException: No files supported by provider at content://com.memento.data.provider.MementoProvider/audionotes/6 10-13 19:44:53.903: ERROR/TAB(5679): at android.content.ContentProvider.openFile(ContentProvider.java:585)
I have a column named _data for that purpose.

You are a little sparse here. I presume you have a custom ContentProvider?
In any case take a look at How to store large blobs in an android content provider?
(I answered my own question there so I won't reproduce it here.)
It sounds like your ContentProvider isn't matching the uri.
