+/**
+ * FileProvider is a special subclass of {@link ContentProvider} that facilitates secure sharing
+ * of files associated with an app by creating a <code>content://</code> {@link Uri} for a file
+ * instead of a <code>file:///</code> {@link Uri}.
+ * <p>
+ * A content URI allows you to grant read and write access using
+ * temporary access permissions. When you create an {@link Intent} containing
+ * a content URI, in order to send the content URI
+ * to a client app, you can also call {@link Intent#setFlags(int) Intent.setFlags()} to add
+ * permissions. These permissions are available to the client app for as long as the stack for
+ * a receiving {@link android.app.Activity} is active. For an {@link Intent} going to a
+ * {@link android.app.Service}, the permissions are available as long as the
+ * {@link android.app.Service} is running.
+ * <p>
+ * In comparison, to control access to a <code>file:///</code> {@link Uri} you have to modify the
+ * file system permissions of the underlying file. The permissions you provide become available to
+ * <em>any</em> app, and remain in effect until you change them. This level of access is
+ * fundamentally insecure.
+ * <p>
+ * The increased level of file access security offered by a content URI
+ * makes FileProvider a key part of Android's security infrastructure.
+ * <p>
+ * This overview of FileProvider includes the following topics:
+ * </p>
+ * <ol>
+ *     <li><a href="#ProviderDefinition">Defining a FileProvider</a></li>
+ *     <li><a href="#SpecifyFiles">Specifying Available Files</a></li>
+ *     <li><a href="#GetUri">Retrieving the Content URI for a File</li>
+ *     <li><a href="#Permissions">Granting Temporary Permissions to a URI</a></li>
+ *     <li><a href="#ServeUri">Serving a Content URI to Another App</a></li>
+ * </ol>
+ * <h3 id="ProviderDefinition">Defining a FileProvider</h3>
+ * <p>
+ * Since the default functionality of FileProvider includes content URI generation for files, you
+ * don't need to define a subclass in code. Instead, you can include a FileProvider in your app
+ * by specifying it entirely in XML. To specify the FileProvider component itself, add a
+ * <code><a href="{@docRoot}guide/topics/manifest/provider-element.html">&lt;provider&gt;</a></code>
+ * element to your app manifest. Set the <code>android:name</code> attribute to
+ * <code>androidx.core.content.FileProvider</code>. Set the <code>android:authorities</code>
+ * attribute to a URI authority based on a domain you control; for example, if you control the
+ * domain <code>mydomain.com</code> you should use the authority
+ * <code>com.mydomain.fileprovider</code>. Set the <code>android:exported</code> attribute to
+ * <code>false</code>; the FileProvider does not need to be public. Set the
+ * <a href="{@docRoot}guide/topics/manifest/provider-element.html#gprmsn"
+ * >android:grantUriPermissions</a> attribute to <code>true</code>, to allow you
+ * to grant temporary access to files. For example:
+ * <pre class="prettyprint">
+ *&lt;manifest&gt;
+ *    ...
+ *    &lt;application&gt;
+ *        ...
+ *        &lt;provider
+ *            android:name="androidx.core.content.FileProvider"
+ *            android:authorities="com.mydomain.fileprovider"
+ *            android:exported="false"
+ *            android:grantUriPermissions="true"&gt;
+ *            ...
+ *        &lt;/provider&gt;
+ *        ...
+ *    &lt;/application&gt;
+ *&lt;/manifest&gt;</pre>
+ * <p>
+ * If you want to override any of the default behavior of FileProvider methods, extend
+ * the FileProvider class and use the fully-qualified class name in the <code>android:name</code>
+ * attribute of the <code>&lt;provider&gt;</code> element.
+ * <h3 id="SpecifyFiles">Specifying Available Files</h3>
+ * A FileProvider can only generate a content URI for files in directories that you specify
+ * beforehand. To specify a directory, specify the its storage area and path in XML, using child
+ * elements of the <code>&lt;paths&gt;</code> element.
+ * For example, the following <code>paths</code> element tells FileProvider that you intend to
+ * request content URIs for the <code>images/</code> subdirectory of your private file area.
+ * <pre class="prettyprint">
+ *&lt;paths xmlns:android="http://schemas.android.com/apk/res/android"&gt;
+ *    &lt;files-path name="my_images" path="images/"/&gt;
+ *    ...
+ *&lt;/paths&gt;
+ *</pre>
+ * <p>
+ * The <code>&lt;paths&gt;</code> element must contain one or more of the following child elements:
+ * </p>
+ * <dl>
+ *     <dt>
+ * <pre class="prettyprint">
+ *&lt;files-path name="<i>name</i>" path="<i>path</i>" /&gt;
+ *</pre>
+ *     </dt>
+ *     <dd>
+ *     Represents files in the <code>files/</code> subdirectory of your app's internal storage
+ *     area. This subdirectory is the same as the value returned by {@link Context#getFilesDir()
+ *     Context.getFilesDir()}.
+ *     </dd>
+ *     <dt>
+ * <pre>
+ *&lt;cache-path name="<i>name</i>" path="<i>path</i>" /&gt;
+ *</pre>
+ *     <dt>
+ *     <dd>
+ *     Represents files in the cache subdirectory of your app's internal storage area. The root path
+ *     of this subdirectory is the same as the value returned by {@link Context#getCacheDir()
+ *     getCacheDir()}.
+ *     </dd>
+ *     <dt>

+ *</pre>
+ *     </dt>
+ *     <dd>
+ *     Represents files in the root of the external storage area. The root path of this subdirectory
+ *     is the same as the value returned by
+ *     {@link Environment#getExternalStorageDirectory() Environment.getExternalStorageDirectory()}.
+ *     </dd>
+ *     <dt>
+ * <pre class="prettyprint">
+ *&lt;external-files-path name="<i>name</i>" path="<i>path</i>" /&gt;
+ *</pre>
+ *     </dt>
+ *     <dd>
+ *     Represents files in the root of your app's external storage area. The root path of this
+ *     subdirectory is the same as the value returned by
+ *     {@code Context#getExternalFilesDir(String) Context.getExternalFilesDir(null)}.
+ *     </dd>
+ *     <dt>
+ * <pre class="prettyprint">
+ *&lt;external-cache-path name="<i>name</i>" path="<i>path</i>" /&gt;
+ *</pre>
+ *     </dt>
+ *     <dd>
+ *     Represents files in the root of your app's external cache area. The root path of this
+ *     subdirectory is the same as the value returned by
+ *     {@link Context#getExternalCacheDir() Context.getExternalCacheDir()}.
+ *     </dd>
+ *     <dt>
+ * <pre class="prettyprint">
+ *&lt;external-media-path name="<i>name</i>" path="<i>path</i>" /&gt;
+ *</pre>
+ *     </dt>
+ *     <dd>
+ *     Represents files in the root of your app's external media area. The root path of this
+ *     subdirectory is the same as the value returned by the first result of
+ *     {@link Context#getExternalMediaDirs() Context.getExternalMediaDirs()}.
+ *     <p><strong>Note:</strong> this directory is only available on API 21+ devices.</p>
+ *     </dd>
+ * </dl>
+ * <p>
+ *     These child elements all use the same attributes:
+ * </p>
+ * <dl>
+ *     <dt>
+ *         <code>name="<i>name</i>"</code>
+ *     </dt>
+ *     <dd>
+ *         A URI path segment. To enforce security, this value hides the name of the subdirectory
+ *         you're sharing. The subdirectory name for this value is contained in the
+ *         <code>path</code> attribute.
+ *     </dd>
+ *     <dt>
+ *         <code>path="<i>path</i>"</code>
+ *     </dt>
+ *     <dd>
+ *         The subdirectory you're sharing. While the <code>name</code> attribute is a URI path
+ *         segment, the <code>path</code> value is an actual subdirectory name. Notice that the
+ *         value refers to a <b>subdirectory</b>, not an individual file or files. You can't
+ *         share a single file by its file name, nor can you specify a subset of files using
+ *         wildcards.
+ *     </dd>
+ * </dl>
+ * <p>
+ * You must specify a child element of <code>&lt;paths&gt;</code> for each directory that contains
+ * files for which you want content URIs. For example, these XML elements specify two directories:
+ * <pre class="prettyprint">
+ *&lt;paths xmlns:android="http://schemas.android.com/apk/res/android"&gt;
+ *    &lt;files-path name="my_images" path="images/"/&gt;
+ *    &lt;files-path name="my_docs" path="docs/"/&gt;
+ *&lt;/paths&gt;
+ *</pre>
+ * <p>
+ * Put the <code>&lt;paths&gt;</code> element and its children in an XML file in your project.
+ * For example, you can add them to a new file called <code>res/xml/file_paths.xml</code>.
+ * To link this file to the FileProvider, add a
+ * <a href="{@docRoot}guide/topics/manifest/meta-data-element.html">&lt;meta-data&gt;</a> element
+ * as a child of the <code>&lt;provider&gt;</code> element that defines the FileProvider. Set the
+ * <code>&lt;meta-data&gt;</code> element's "android:name" attribute to
+ * <code>android.support.FILE_PROVIDER_PATHS</code>. Set the element's "android:resource" attribute
+ * to <code>&#64;xml/file_paths</code> (notice that you don't specify the <code>.xml</code>
+ * extension). For example:
+ * <pre class="prettyprint">
+ *&lt;provider
+ *    android:name="androidx.core.content.FileProvider"
+ *    android:authorities="com.mydomain.fileprovider"
+ *    android:exported="false"

+ * <h3 id="GetUri">Generating the Content URI for a File</h3>
+ * <p>
+ * To share a file with another app using a content URI, your app has to generate the content URI.
+ * To generate the content URI, create a new {@link File} for the file, then pass the {@link File}
+ * to {@link #getUriForFile(Context, String, File) getUriForFile()}. You can send the content URI
+ * returned by {@link #getUriForFile(Context, String, File) getUriForFile()} to another app in an
+ * {@link Intent}. The client app that receives the content URI can open the file
+ * and access its contents by calling
+ * {@link android.content.ContentResolver#openFileDescriptor(Uri, String)
+ * ContentResolver.openFileDescriptor} to get a {@link ParcelFileDescriptor}.
+ * <p>
+ * For example, suppose your app is offering files to other apps with a FileProvider that has the
+ * authority <code>com.mydomain.fileprovider</code>. To get a content URI for the file
+ * <code>default_image.jpg</code> in the <code>images/</code> subdirectory of your internal storage
+ * add the following code:
+ * <pre class="prettyprint">
+ *File imagePath = new File(Context.getFilesDir(), "images");
+ *File newFile = new File(imagePath, "default_image.jpg");
+ *Uri contentUri = getUriForFile(getContext(), "com.mydomain.fileprovider", newFile);
+ *</pre>
+ * As a result of the previous snippet,
+ * {@link #getUriForFile(Context, String, File) getUriForFile()} returns the content URI
+ * <code>content://com.mydomain.fileprovider/my_images/default_image.jpg</code>.
+ * <h3 id="Permissions">Granting Temporary Permissions to a URI</h3>
+ * To grant an access permission to a content URI returned from
+ * {@link #getUriForFile(Context, String, File) getUriForFile()}, do one of the following:
+ * <ul>
+ * <li>
+ *     Call the method
+ *     {@link Context#grantUriPermission(String, Uri, int)
+ *     Context.grantUriPermission(package, Uri, mode_flags)} for the <code>content://</code>
+ *     {@link Uri}, using the desired mode flags. This grants temporary access permission for the
+ *     content URI to the specified package, according to the value of the
+ *     the <code>mode_flags</code> parameter, which you can set to
+ *     {@link Intent#FLAG_GRANT_READ_URI_PERMISSION}, {@link Intent#FLAG_GRANT_WRITE_URI_PERMISSION}
+ *     or both. The permission remains in effect until you revoke it by calling
+ *     {@link Context#revokeUriPermission(Uri, int) revokeUriPermission()} or until the device
+ *     reboots.
+ * </li>
+ * <li>
+ *     Put the content URI in an {@link Intent} by calling {@link Intent#setData(Uri) setData()}.
+ * </li>
+ * <li>
+ *     Next, call the method {@link Intent#setFlags(int) Intent.setFlags()} with either
+ *     {@link Intent#FLAG_GRANT_READ_URI_PERMISSION} or
+ *     {@link Intent#FLAG_GRANT_WRITE_URI_PERMISSION} or both.
+ * </li>
+ * <li>
+ *     Finally, send the {@link Intent} to
+ *     another app. Most often, you do this by calling
+ *     {@link android.app.Activity#setResult(int, Intent) setResult()}.
+ *     <p>
+ *     Permissions granted in an {@link Intent} remain in effect while the stack of the receiving
+ *     {@link android.app.Activity} is active. When the stack finishes, the permissions are
+ *     automatically removed. Permissions granted to one {@link android.app.Activity} in a client
+ *     app are automatically extended to other components of that app.
+ *     </p>
+ * </li>
+ * </ul>
+ * <h3 id="ServeUri">Serving a Content URI to Another App</h3>
+ * <p>
+ * There are a variety of ways to serve the content URI for a file to a client app. One common way
+ * is for the client app to start your app by calling
+ * {@link android.app.Activity#startActivityForResult(Intent, int, Bundle) startActivityResult()},
+ * which sends an {@link Intent} to your app to start an {@link android.app.Activity} in your app.
+ * In response, your app can immediately return a content URI to the client app or present a user
+ * interface that allows the user to pick a file. In the latter case, once the user picks the file
+ * your app can return its content URI. In both cases, your app returns the content URI in an
+ * {@link Intent} sent via {@link android.app.Activity#setResult(int, Intent) setResult()}.
+ * </p>
+ * <p>
+ *  You can also put the content URI in a {@link android.content.ClipData} object and then add the
+ *  object to an {@link Intent} you send to a client app. To do this, call
+ *  {@link Intent#setClipData(ClipData) Intent.setClipData()}. When you use this approach, you can
+ *  add multiple {@link android.content.ClipData} objects to the {@link Intent}, each with its own
+ *  content URI. When you call {@link Intent#setFlags(int) Intent.setFlags()} on the {@link Intent}
+ *  to set temporary access permissions, the same permissions are applied to all of the content
+ *  URIs.
+ * </p>
+ * <p class="note">
+ *  <strong>Note:</strong> The {@link Intent#setClipData(ClipData) Intent.setClipData()} method is
+ *  only available in platform version 16 (Android 4.1) and later. If you want to maintain
+ *  compatibility with previous versions, you should send one content URI at a time in the
+ *  {@link Intent}. Set the action to {@link Intent#ACTION_SEND} and put the URI in data by calling
+ *  {@link Intent#setData setData()}.
+ * </p>
