Android - Using URI permissions with broadcast

I am trying to test whether URI permissions work with Broadcast.

The first app I have has the following code in an activity :

Intent intent = new Intent("com.android.testintent.app.bcast");
intent.setData(contentUri);
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);

sendBroadcast(intent);

The content URI is obtained from a FileProvider.

<provider
        android:name="android.support.v4.content.FileProvider"
        android:authorities="com.android.provider.DataSharing"
        android:exported="false"
        android:grantUriPermissions="true" >
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/paths" />
</provider>

 contentUri = FileProvider.getUriForFile(getApplicationContext(),
                    "com.android.provider.DataSharing", /* file's path */);

 // file's path is correct - I have tested it with activity

In the app receiving the broadcast :

<receiver
        android:name=".MyReceiver"
        android:enabled="true"
        android:exported="true" >

        <intent-filter>
            <action android:name="com.android.testintent.app.bcast" />
        </intent-filter>

</receiver>

The receiver code - onReceive() :

Toast.makeText(context, "Bcast - received", Toast.LENGTH_LONG).show();

Uri uri = intent.getData();

if(uri != null) {

      try {

          InputStream inputStream = context.getContentResolver().openInputStream(uri);

      } 
      catch (Exception e) {

            Log.d("TEST", "Bcast - exception : " + e);
      }
 }

When I pass the URI as null from the first app, the broadcast reaches the receiver and I can see the toast message. However, when the URI is not null, my receiver does not even receive the broadcast.

Can anyone point out the reason for this behavior ?

Edit :

I edited the Receiver :

<receiver
        android:name=".MyReceiver"
        android:enabled="true"
        android:exported="true" >

        <intent-filter>
            <action android:name="com.android.teachintent.app.bcast1" />
            <data android:mimeType="image/jpeg" />
        </intent-filter>

</receiver>

I added the mime type. I did this based on the rule (see here)

An intent that contains both a URI and a MIME type (either explicit or 
inferable from the URI) passes the MIME type part of the test only if 
that type matches a type listed in the filter. It passes the URI 
part of the test either if its URI matches a URI in the filter or if 
it has a content: or file: URI and the filter does not specify a URI. 
In other words, a component is presumed to support content: and file: 
data if its filter lists only a MIME type.

Now I get the exception in the receiver :

D/TEST﹕ Bcast - exception : java.lang.SecurityException: Permission Denial: 
opening provider android.support.v4.content.FileProvider from 
ProcessRecord{529a7b60 1593:com.android.testintent.app/u0a55} 
(pid=1593, uid=10055) that is not exported from uid 10059

If I try to export the FileProvider, Android throws an exception saying Providers are not allowed to be exported.

What can I do to resolve this ?

The reason is that you are not matching the <intent-filter>. Your <intent-filter> is only matching on the action string. You also need to qualify for your Uri, via a <data> element indicating that you support the content scheme the right MIME type.
