Question

IllegalArgumentException: Unknown URL content://

^ Having a nightmare with the above. I've checked my variables and paths but can't see what the issue is? Greatly appreciate any pointers!

Here's my trace.

Could your please provide code of how you call insert method? Also you place <provider /> tag inside <activity /> tag, which may be the problem as well. – Kall

Okay, so I have moved the provider outside of activity. Same issue? The insert is in teh DBHelper – Gloria

As a side note: why does your onCreate method returns false? And a possible bug: in addFilm method you insert data in ContentProvider as well as in your db, which leads to useless data duplication. – Kall

Thanks. Looks like it is working now. I appreciate the help. Haven't got the rep to vote up yet. Thanks – Gloria

Answer 1

First, move <provider> to be a child of <application>, not <activity>.

Second, change android:exported="true" to android:exported="false", until such time as you secure your ContentProvider. As it stands, once you fix the <provider> element location as noted above, any app can read and write anything in your provider, which is unlikely to be what the user wants.

It doesn't address the problem at all, if the author calls insert method with incorrect URI. – Kall

@Arkadiy: Good point -- I missed that. @PhilWiggins: you have at least one typo in your authority strings -- F vs. f in the filmProvider portion of the authority. – Saltish

Really appreciate the help. All sorted!! – Gloria

I added <provider> outside of <application>. Thank you to help me. – Allan

Answer 2

I have added package name in authorities.that's why I got this issue.I have to add Provider name in authorities.

  <provider
            android:name="LoginContentProvider"
            android:authorities="com.provider.name.team"
            android:exported="false" />
