+Mastodon – didžiausias decentralizuotas socialinis tinklas internete. Vietoj vienos svetainės tai yra milijonų naudotojų, priklausančių nepriklausomoms bendruomenėms, kurios gali sklandžiai bendrauti tarpusavyje, tinklas. Nesvarbu, kuo domiesi, Mastodon gali sutikti aistringų žmonių, skelbiančių apie tai!
+
+Prisijunk prie bendruomenės ir susikurk savo profilį. Rask ir sek žavius žmones bei skaityk jų įrašus chronologinėje laiko skalėje be reklamų. Išreikšk save su pasirinktais jaustukais, vaizdais, GIF, vaizdo ir garso įrašais 500 simbolių įrašuose. Atsakyk į gijas ir perrašyk bet kurio asmens įrašus, kad galėtum dalytis puikiais dalykais. Ieškok naujų paskyrų sekti ir tendencingų saitažodžių, kad praplėstum savo tinklą.
+
+Mastodon sukurtas daugiausia dėmesio skiriant privatumui ir saugumui. Nuspręsk, ar tavo įrašai bus bendrinami tavo sekėjams, tik tavo paminėtiems žmonėms, ar visam pasauliui. Turinio įspėjimai leidžia paslėpti įrašus, kuriuose yra jautrios ar dirginančios medžiagos, kol būsi pasiruošęs (-usi) su jais bendrauti. Kiekviena bendruomenė turi savo gaires ir prižiūrėtojus, kad jos nariai būtų saugūs, o patikimi blokavimo ir pranešimo įrankiai padeda užkirsti kelią piktnaudžiavimui.
+
+Daugiau funkcijų:
+
+• Tamsusis režimas: skaityk įrašus šviesiu, tamsiu arba tikru juodu režimu
+• Apklausos: paklausk sekėjų nuomonės ir suskaičiuok balsus
+• Naršyti: tendencingos saitažodžiai ir paskyros – vos nuo vieno prisilietimo
+• Pranešimai: gauk pranešimus apie naujus sekėjus, atsakymus ir tinklaraščių perrašymus
+• Bendrinimas: skelbk tiesiogiai į Mastodon iš bet kurio bendrinimo lapo bet kurioje programėlėje
+• Mielumas: mūsų talismanas yra žavus drambliukas, kurį retkarčiais pamatysi
+
+Mastodon yra registruota ne pelno siekianti organizacija, kurios plėtra yra tiesiogiai paremta aukomis. Nėra jokios reklamos, jokių monetizacijos ir rizikos kapitalo, ir mes planuojame, kad taip ir liks.

+/**
+ * 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 class="prettyprint">
+ *&lt;external-path name="<i>name</i>" path="<i>path</i>" /&gt;
+ *</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"
+ *    android:grantUriPermissions="true"&gt;
+ *    &lt;meta-data
+ *        android:name="android.support.FILE_PROVIDER_PATHS"
+ *        android:resource="&#64;xml/file_paths" /&gt;
+ *&lt;/provider&gt;
+ *</pre>
+ * <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>
