In AndroidManifest.xml
the following intent-filter
allows to display the Android app while you select same types to share (all images or all videos).
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
<action android:name="android.intent.action.SEND" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="image/*" />
<data android:mimeType="audio/*"/>
<data android:mimeType="video/*"/>
</intent-filter>
But if user select different types of content (image + video) the app with this intent is not is displaying in the share window.
So the question is - what intent should be used to display the app and allow to share files with different types simultaneously?
Thank you!
As @CommonsWare wrote android.intent.action.SEND_MULTIPLE
will enable this option.
