You might be missing meta-data in your manifest file. Try adding this

<provider
            android:name="android.support.v4.content.FileProvider"
            android:authorities="${applicationId}"
            android:exported="false"
            android:grantUriPermissions="true" >
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/filepaths" />
        </provider>

and the filepaths like this:

<?xml version="1.0" encoding="utf-8"?>
<paths>
    <cache-path
        name="camera_photos"
        path="" />
</paths>

（spent hours with same problem.）
