IllegalArgumentException: Unknown URL content:// CONTENT

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.

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.

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" />
