Please note that if you plan to use export module, you need to put specific provider in your app manifest:


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


and the needed provider_paths file


<?xml version="1.0" encoding="utf-8"?>
<paths>
    <files-path name="export" path="." />
</paths>


into xml folder here:
