-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and

-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

+/**
+ * CloseGuard is a mechanism for flagging implicit finalizer cleanup of
+ * resources that should have been cleaned up by explicit close
+ * methods (aka "explicit termination methods" in Effective Java).
+ * <p>
+ * A simple example: <pre>   {@code
+ *   class Foo {
+ *
+ *       private final CloseGuard guard = CloseGuard.get();
+ *
+ *       ...
+ *
+ *       public Foo() {
+ *           ...;
+ *           guard.open("cleanup");
+ *       }
+ *
+ *       public void cleanup() {
+ *          guard.close();
+ *          ...;
+ *       }
+ *
+ *       protected void finalize() throws Throwable {
+ *           try {
+ *               // Note that guard could be null if the constructor threw.
+ *               if (guard != null) {
+ *                   guard.warnIfOpen();
+ *               }
+ *               cleanup();
+ *           } finally {
+ *               super.finalize();
+ *           }
+ *       }
+ *   }
+ * }</pre>
+ *
+ * In usage where the resource to be explicitly cleaned up is
+ * allocated after object construction, CloseGuard protection can
+ * be deferred. For example: <pre>   {@code
+ *   class Bar {
+ *
+ *       private final CloseGuard guard = CloseGuard.get();
+ *
+ *       ...
+ *
+ *       public Bar() {

+ *       }
+ *
+ *       public void connect() {
+ *          ...;
+ *          guard.open("cleanup");
+ *       }
+ *
+ *       public void cleanup() {
+ *          guard.close();
+ *          ...;
+ *          Reference.reachabilityFence(this);
+ *          // For full correctness in the absence of a close() call, other methods may also need
+ *          // reachabilityFence() calls.
+ *       }
+ *
+ *       protected void finalize() throws Throwable {
+ *           try {
+ *               // Note that guard could be null if the constructor threw.
+ *               if (guard != null) {

+ *       }
+ *   }
+ * }</pre>
+ *
+ * When used in a constructor, calls to {@code open} should occur at

+This xml file allows customization of Android multiuser user types.
+It is parsed by frameworks/base/services/core/java/com/android/server/pm/UserTypeFactory.java.
+
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
+++++++++++++++++++++++++++++++++++++++++   IMPORTANT NOTE   ++++++++++++++++++++++++++++++++++++++++
+Although device customization is possible here, it is largely untested.
+In particular, although this file allows new profile types to be created, and allows modifying the
+number of managed profiles allowed on the device, the consequences of doing so is untested.
+OEMs are advised to test very carefully any significant customization.
+Further support is planned for later releases.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
+
+Pre-defined (AOSP) user types can be customized and new types can be defined. The syntax is the
+same in both cases.
+
+Currently, only profiles (not full or system users) can be freely customized/defined.
+Full users (i.e. non-system, non-profile) users cannot be defined, and the only property of them
+that can be customized are the default-restrictions.
+System users cannot be customized here; their default-restrictions must be set using
+com.android.internal.R.array.config_defaultFirstUserRestrictions.
+
+The following example modifies two AOSP user types (the FULL user android.os.usertype.full.SECONDARY
+and the PROFILE user android.os.usertype.profile.MANAGED) and creates a new PROFILE user type
+(com.example.profilename):
+
+<user-types>
+    <full-type name="android.os.usertype.full.SECONDARY" >
+        <default-restrictions no_sms="true" />
+    </full-type>
+
+    <profile-type
+        name='android.os.usertype.profile.MANAGED'
+        max-allowed-per-parent='2'
+        icon-badge='@android:drawable/ic_corp_icon_badge_case'
+        badge-plain='@android:drawable/ic_corp_badge_case'
+        badge-no-background='@android:drawable/ic_corp_badge_no_background' >
+        <badge-labels>
+            <item res='@android:string/managed_profile_label_badge' />
+            <item res='@android:string/managed_profile_label_badge_2' />
+        </badge-labels>
+        <badge-colors>
+            <item res='@android:color/profile_badge_1' />
+            <item res='@android:color/profile_badge_2' />
+        </badge-colors>
+        <default-restrictions no_sms="true" no_outgoing_calls="true" />
+    </profile-type>
+
+    <profile-type
+        name="com.example.profilename"
+        max-allowed-per-parent="2" />
+</user-types>
+
+Mandatory attributes:
+    name
+
+Supported optional properties (to be used as shown in the example above) are as follows.
+For profile and full users:
+    default-restrictions (with values defined in UserRestrictionUtils.USER_RESTRICTIONS)
+For profile users only:
+    max-allowed-per-parent
+    icon-badge
+    badge-plain
+    badge-no-background
+    badge-labels
+    badge-colors
+
+See UserTypeFactory.java and UserTypeDetails.java for the meaning (and default values) of these
+fields.
+
+Any property that is specified overwrites the AOSP default. For example, if there is no
+default-restrictions element, then the AOSP defaults for that user type will be used; however, if
+there is a default-restrictions element, then the AOSP default restrictions will be completely
+ignored and will instead obey this configuration.
+
+If this file is updated, the properties of any pre-existing user types will be updated too.
+Note, however, that default-restrictions refers to the restrictions applied at the time of user
+creation; therefore, the active restrictions of any pre-existing users will not be updated.
