How to access contentResolver of a fragment in a different activity?

Issue

The situation is that I have a MainFragment (extends a ListFragment, implements LoaderManager.LoaderCallbacks<Cursor>) which is called from MainActivity. A new activity DetailsActivity is called from that fragment to display the content of a certain item in a list view getting the id as an intent argument. How can I getContentResolver() to access its methods using a Uri?

The error right now I get from accessing content resolver is:

`java.lang.IllegalArgumentException: Unknown URL content://com.xxxx.words.contentprovider/words`

uri = Uri.parse(MainContentProvider.CONTENT_URI.toString());
            getContentResolver().insert(uri, contentValues);

CONTENT_URI = Uri.parse("content://" + "com.xxxx.words.contentprovider" + "/" + "words");

android manifest file:

<provider
        android:authorities="com.xxxx.words.contentprovider.MainContentProvider"
        android:name=".contentprovider.MainContentProvider"/>

or should i just return a Bundle from that DetailsActivity and access the content provider in the initial fragment?

Solution

The error right now I get from accessing content resolver is

That is because your Uri does not match your android:authorities. Your android:authorities is com.xxxx.words.contentprovider.MainContentProvider. Your Uri uses com.xxxx.words.contentprovider. These are not the same, and they need to be the same.

Also, please add android:exported to your <provider>, set to true (if third-party apps should have complete access to the provider) or false (if they should not).
