    android:grantUriPermissions="true" >

    <meta-data
        android:name="android.support.FILE_PROVIDER_PATHS"
        android:resource="@xml/provider_paths" />
</provider>

//provider_paths

<?xml version="1.0" encoding="utf-8"?>
<resources>
<paths>
    <!--360-->
    <!--<root-path path="" name="camera_photos" />-->
