+<!--
+This XML file declares which system packages should be initially installed for new users based on
+the type of user. All system packages on the device should ideally have an entry in an xml file
+(keys by its manifest name).
+
+Main user-types (every user will be at least one of these types) are:
+  SYSTEM    (user 0)
+  FULL      (any non-profile human user)
+  PROFILE   (profile human user)
+
+Additional optional types are:   GUEST,    RESTRICTED,    MANAGED_PROFILE,    EPHEMERAL,    DEMO
+
+The meaning of each of these user types is delineated by flags in
+frameworks/base/core/java/android/content/pm/UserInfo.java.
+See frameworks/base/services/core/java/com/android/server/pm/UserSystemPackageInstaller#getFlagsFromUserTypes
+
+The following three examples should cover most normal cases:
+
+1. For a system package to be pre-installed only in user 0:
+
+   <install-in-user-type package="com.android.example">
+       <install-in user-type="SYSTEM">
+   </install-in-user-type>
+
+
+2. For a system package to be pre-installed on all human users (e.g. a web browser), i.e. to be
+installed on any user of type type FULL or PROFILE (since this covers all human users):
+
+   <install-in-user-type package="com.android.example">
+       <install-in user-type="FULL">
+       <install-in user-type="PROFILE">
+   </install-in-user-type>
+
+
+3. For a system package to be pre-installed on all human users except for profile users (e.g. a
+wallpaper app, since profiles cannot display wallpaper):
+
+   <install-in-user-type package="com.android.example">
+       <install-in user-type="FULL">
+   </install-in-user-type>
+
+
+Some system packages truly are required to be on all users, regardless of type, in which case use:
+   <install-in-user-type package="com.android.example">
+       <install-in user-type="SYSTEM">
+       <install-in user-type="FULL">
+       <install-in user-type="PROFILE">
+   </install-in-user-type>
+
+More fine-grained options are also available (see below). Additionally, packages can blacklist
+user types. Blacklists override any whitelisting (in any file).
+E.g.
+     <install-in-user-type package="com.android.example">
+        <install-in user-type="FULL" />
+        <do-not-install-in user-type="GUEST" />
+    </install-in-user-type>
+
+If a user is of type FULL and GUEST, this package will NOT be installed, because the
+'do-not-install-in' takes precedence over 'install-in'.
+
+The way that a device treats system packages that do not have any entry (for any user type) at all
+is determined by the config resource value config_userTypePackageWhitelistMode.
+See frameworks/base/core/res/res/values/config.xml#config_userTypePackageWhitelistMode.
+
+Changes to the whitelist during system updates can result in installing new system packages
+to pre-existing users, but cannot uninstall system packages from pre-existing users.

-/**
- * MediaPlayer2 class can be used to control playback of audio/video files and streams.
- *
- * <p>
- * This API is not generally intended for third party application developers.
- * Use the <a href="{@docRoot}jetpack/androidx.html">AndroidX</a>
- * <a href="{@docRoot}reference/androidx/media2/package-summary.html">Media2 Library</a>
- * for consistent behavior across all devices.
- *
- * <p>Topics covered here are:
- * <ol>
- * <li><a href="#PlayerStates">Player states</a>
- * <li><a href="#InvalidStates">Invalid method calls</a>
- * <li><a href="#Permissions">Permissions</a>
- * <li><a href="#Callbacks">Callbacks</a>
- * </ol>
- *
- *
- * <h3 id="PlayerStates">Player states</h3>
- *
- * <p>The playback control of audio/video files is managed as a state machine.</p>
- * <p><div style="text-align:center;"><img src="../../../images/mediaplayer2_state_diagram.png"
- *         alt="MediaPlayer2 State diagram"
- *         border="0" /></div></p>
- * <p>The MediaPlayer2 object has five states:</p>
- * <ol>
- *     <li><p>{@link #PLAYER_STATE_IDLE}: MediaPlayer2 is in the <strong>Idle</strong>
- *         state after it's created, or after calling {@link #reset()}.</p>
- *
- *         <p>While in this state, you should call
- *         {@link #setDataSource setDataSource}. It is a good
- *         programming practice to register an {@link EventCallback#onCallCompleted onCallCompleted}
- *         <a href="#Callbacks">callback</a> and watch for {@link #CALL_STATUS_BAD_VALUE} and
- *         {@link #CALL_STATUS_ERROR_IO}, which might be caused by <code>setDataSource</code>.
- *         </p>
- *
- *         <p>Calling {@link #prepare()} transfers a MediaPlayer2 object to
- *         the <strong>Prepared</strong> state. Note
- *         that {@link #prepare()} is asynchronous. When the preparation completes,
- *         if you register an {@link EventCallback#onInfo onInfo} <a href="#Callbacks">callback</a>,
- *         the player executes the callback
- *         with {@link #MEDIA_INFO_PREPARED} and transitions to the
- *         <strong>Prepared</strong> state.</p>
- *         </li>
- *
- *     <li>{@link #PLAYER_STATE_PREPARED}: A MediaPlayer object must be in the
- *         <strong>Prepared</strong> state before playback can be started for the first time.
- *         While in this state, you can set player properties
- *         such as audio/sound volume and looping by invoking the corresponding set methods.
- *         Calling {@link #play()} transfers a MediaPlayer2 object to
- *         the <strong>Playing</strong> state.
- *      </li>
- *
- *     <li>{@link #PLAYER_STATE_PLAYING}:
- *         <p>The player plays the data source while in this state.
- *         If you register an {@link EventCallback#onInfo onInfo} <a href="#Callbacks">callback</a>,
- *         the player regularly executes the callback with
- *         {@link #MEDIA_INFO_BUFFERING_UPDATE}.
- *         This allows applications to keep track of the buffering status
- *         while streaming audio/video.</p>
- *
- *         <p> When the playback reaches the end of stream, the behavior depends on whether or
- *         not you've enabled looping by calling {@link #loopCurrent}:</p>
- *         <ul>
- *         <li>If the looping mode was set to <code>false</code>, the player will transfer
- *         to the <strong>Paused</strong> state. If you registered an {@link EventCallback#onInfo
- *         onInfo} <a href="#Callbacks">callback</a>
- *         the player calls the callback with {@link #MEDIA_INFO_DATA_SOURCE_END} and enters
- *         the <strong>Paused</strong> state.
- *         </li>
- *         <li>If the looping mode was set to <code>true</code>,
- *         the MediaPlayer2 object remains in the <strong>Playing</strong> state and replays its
- *         data source from the beginning.</li>
- *         </ul>
- *         </li>
- *
- *     <li>{@link #PLAYER_STATE_PAUSED}: Audio/video playback pauses while in this state.
- *         Call {@link #play()} to resume playback from the position where it paused.</li>
- *
- *     <li>{@link #PLAYER_STATE_ERROR}: <p>In general, playback might fail due to various
- *          reasons such as unsupported audio/video format, poorly interleaved
- *          audio/video, resolution too high, streaming timeout, and others.
- *          In addition, due to programming errors, a playback
- *          control operation might be performed from an <a href="#InvalidStates">invalid state</a>.
- *          In these cases the player transitions to the <strong>Error</strong> state.</p>
- *
- *          <p>If you register an {@link EventCallback#onError onError}}
- *          <a href="#Callbacks">callback</a>,
- *          the callback will be performed when entering the state. When programming errors happen,
- *          such as calling {@link #prepare()} and
- *          {@link #setDataSource} methods
- *          from an <a href="#InvalidStates">invalid state</a>, the callback is called with
- *          {@link #CALL_STATUS_INVALID_OPERATION}. The MediaPlayer2 object enters the
- *          <strong>Error</strong> state whether or not a callback exists. </p>
- *
- *          <p>To recover from an error and reuse a MediaPlayer2 object that is in the <strong>
- *          Error</strong> state,
- *          call {@link #reset()}. The object will return to the <strong>Idle</strong>
- *          state and all state information will be lost.</p>
- *          </li>
- * </ol>
- *
- * <p>You should follow these best practices when coding an app that uses MediaPlayer2:</p>
- *
- * <ul>
- *
- * <li>Use <a href="#Callbacks">callbacks</a> to respond to state changes and errors.</li>
- *
- * <li>When  a MediaPlayer2 object is no longer being used, call {@link #close()} as soon as
- * possible to release the resources used by the internal player engine associated with the
- * MediaPlayer2. Failure to call {@link #close()} may cause subsequent instances of
- * MediaPlayer2 objects to fallback to software implementations or fail altogether.
- * You cannot use MediaPlayer2
- * after you call {@link #close()}. There is no way to bring it back to any other state.</li>
- *
- * <li>The current playback position can be retrieved with a call to
- * {@link #getCurrentPosition()},
- * which is helpful for applications such as a Music player that need to keep track of the playback
- * progress.</li>
- *
- * <li>The playback position can be adjusted with a call to {@link #seekTo}. Although the
- * asynchronous {@link #seekTo} call returns right away, the actual seek operation may take a
- * while to finish, especially for audio/video being streamed. If you register an
- * {@link EventCallback#onCallCompleted onCallCompleted} <a href="#Callbacks">callback</a>,
- * the callback is
- * called When the seek operation completes with {@link #CALL_COMPLETED_SEEK_TO}.</li>
- *
- * <li>You can call {@link #seekTo} from the <strong>Paused</strong> state.
- * In this case, if you are playing a video stream and
- * the requested position is valid  one video frame is displayed.</li>
- *
- * </ul>
- *
- * <h3 id="InvalidStates">Invalid method calls</h3>
- *
- * <p>The only methods you safely call from the <strong>Error</strong> state are
- * {@link #close},
- * {@link #reset},
- * {@link #notifyWhenCommandLabelReached},
- * {@link #clearPendingCommands},
- * {@link #registerEventCallback},
- * {@link #unregisterEventCallback}
- * and {@link #getState}.
- * Any other methods might throw an exception, return meaningless data, or invoke a
- * {@link EventCallback#onCallCompleted onCallCompleted} with an error code.</p>
- *
- * <p>Most methods can be called from any non-Error state. They will either perform their work or
- * silently have no effect. The following table lists the methods that will invoke a
- * {@link EventCallback#onCallCompleted onCallCompleted} with an error code
- * or throw an exception when they are called from the associated invalid states.</p>
- *
- * <table border="0" cellspacing="0" cellpadding="0">
- * <tr><th>Method Name</th>

- * <h3 id="Permissions">Permissions</h3>
- * <p>This class requires the {@link android.Manifest.permission#INTERNET} permission
- * when used with network-based content.
- *
- * <h3 id="Callbacks">Callbacks</h3>
- * <p>Many errors do not result in a transition to the  <strong>Error</strong> state.
- * It is good programming practice to register callback listeners using
- * {@link #registerEventCallback}.
- * You can receive a callback at any time and from any state.</p>
- *
- * <p>If it's important for your app to respond to state changes (for instance, to update the
- * controls on a transport UI), you should register an
- * {@link EventCallback#onCallCompleted onCallCompleted} and
- * detect state change commands by testing the <code>what</code> parameter for a callback from one
- * of the state transition methods: {@link #CALL_COMPLETED_PREPARE}, {@link #CALL_COMPLETED_PLAY},
- * and {@link #CALL_COMPLETED_PAUSE}.
- * Then check the <code>status</code> parameter. The value {@link #CALL_STATUS_NO_ERROR} indicates a
- * successful transition. Any other value will be an error. Call {@link #getState()} to
- * determine the current state. </p>

-/**
- * A simple in-process event bus.  It is simple because we can make assumptions about the state of
- * SystemUI and Recent's lifecycle.
- *
- * <p>
- * Currently, there is a single EventBus that handles {@link EventBus.Event}s for each subscriber
- * on the main application thread.  Publishers can send() events to synchronously call subscribers
- * of that event, or post() events to be processed in the next run of the {@link Looper}.
- *
- * <p>
- * Subscribers must be registered with a particular EventBus before they will receive events, and
- * handler methods must match a specific signature.
- *
- * <p>
- * Event method signature:<ul>
- * <li>Methods must be public final
- * <li>Methods must return void
- * <li>Methods must be called "onBusEvent"
- * <li>Methods must take one parameter, of class type deriving from {@link EventBus.Event}
- * </ul>
- *
- * </p>
- * Each subscriber can be registered with a given priority (default 1), and events will be dispatch
- * in decreasing order of priority.  For subscribers with the same priority, events will be
- * dispatched by latest registration time to earliest.
- *
- * <p>
- * Caveats:<ul>
- * <li>The EventBus keeps a {@link WeakReference} to the publisher to prevent memory leaks, so
- * there must be another strong reference to the publisher for it to not get garbage-collected and
- * continue receiving events.
- * <li>Because the event handlers are called back using reflection, the EventBus is not intended
- * for use in tight, performance criticial loops.  For most user input/system callback events, this
- * is generally of low enough frequency to use the EventBus.
- * <li>Because the event handlers are called back using reflection, there will often be no
- * references to them from actual code.  The proguard configuration will be need to be updated to
- * keep these extra methods:
- *
- * -keepclassmembers class ** {
- * public void onBusEvent(**);
- * public void onInterprocessBusEvent(**);
- * }
- * -keepclassmembers class ** extends **.EventBus$InterprocessEvent {
- * public <init>(android.os.Bundle);
- * }
- *
- * <li>Subscriber registration can be expensive depending on the subscriber's {@link Class}.  This
- * is only done once per class type, but if possible, it is best to pre-register an instance of
- * that class beforehand or when idle.
- * <li>Each event should be sent once.  Events may hold internal information about the current
- * dispatch, or may be queued to be dispatched on another thread (if posted from a non-main thread),
- * so it may be unsafe to edit, change, or re-send the event again.
- * <li>Events should follow a pattern of public-final POD (plain old data) objects, where they are
- * initialized by the constructor and read by each subscriber of that event.  Subscribers should
- * never alter events as they are processed, and this enforces that pattern.
- * </ul>
- *
- * <p>
- * Future optimizations:
- * <li>throw exception/log when a subscriber loses the reference
- * <li>trace cost per registration & invocation
- * <li>trace cross-process invocation
- * <li>register(subscriber, Class&lt;?&gt;...) -- pass in exact class types you want registered
- * <li>setSubscriberEventHandlerPriority(subscriber, Class<Event>, priority)
- * <li>allow subscribers to implement interface, ie. EventBus.Subscriber, which lets then test a
- * message before invocation (ie. check if task id == this task id)
- * <li>add postOnce() which automatically debounces
- * <li>add postDelayed() which delays / postDelayedOnce() which delays and bounces
- * <li>consolidate register() and registerInterprocess()
- * <li>sendForResult&lt;ReturnType&gt;(Event) to send and get a result, but who will send the
- * result?

+ * a concatenation of string literals) and a vararg array of parameters for the formatter.
+ *
+ * The syntax for the message string is a subset of {@code java.util.Formatter} syntax.
+ * Supported conversions:
+ * %b - boolean
+ * %d, %o and %x - integral type (Short, Integer or Long)
+ * %f, %e and %g - floating point type (Float or Double)
+ * %s - string
+ * %% - a literal percent character
+ * The width and precision modifiers are supported, argument_index and flags are not.

+ * Methods in this class are stubs, that are replaced by optimised versions by the ProtoLogTool

+This test only runs on rooted / debuggable device.
+
+The test tries to install subsets of base.{apk,dm}, split.{apk,dm} and their
+corresponding .fsv_sig files (generated by build rule). If installed, the
+tests also tries to tamper with the file at absolute disk offset to verify
+if fs-verity is effective.

+How to generate dex metadata (.dm)
+==================================
