 *
 * ```xml
 * <manifest>
 *   <application>
 *     <provider
 *       android:name="com.facebook.react.modules.blob.BlobProvider"
 *       android:authorities="@string/blob_provider_authority"
 *       android:exported="false"
 *     />
 *   </application>
 * </manifest>
 * ```
 * And then define the `blob_provider_authority` string in `res/values/strings.xml`.
 * Use a dotted name that's entirely unique to your app:
 *
 * ```xml
 * <resources>
 *   <string name="blob_provider_authority">your.app.package.blobs</string>
 * </resources>
 * ```
