-
-      You may add Your own copyright statement to Your modifications and

-      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.

-      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

-      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.

-
-      "Object" form shall mean any form resulting from mechanical
-      transformation or translation of a Source form, including but
-      not limited to compiled object code, generated documentation,
-      and conversions to other media types.
-
-      "Work" shall mean the work of authorship, whether in Source or
-      Object form, made available under the License, as indicated by a
-      copyright notice that is included in or attached to the work
-      (an example is provided in the Appendix below).
-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain

-      the Work and Derivative Works thereof.
-
-      "Contribution" shall mean any work of authorship, including
-      the original version of the Work and any modifications or additions

-
-      "Contributor" shall mean Licensor and any individual or Legal Entity

-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,
-      publicly display, publicly perform, sublicense, and distribute the
-      Work and such Derivative Works in Source or Object form.
-

-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.

-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You

-          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,

-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and

-          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

+# Fuzzer for libmediametricsservice
+
+## Plugin Design Considerations
+The fuzzer plugin for libmediametricsservice is designed based on the
+understanding of the service and tries to achieve the following:
+
+##### Maximize code coverage
+The configuration parameters are not hardcoded, but instead selected based on
+incoming data. This ensures more code paths are reached by the fuzzer.
+
+Media Metrics Service contains the following modules:
+1. Media Metrics Item Manipulation (module name: `Item`)
+2. Media Metrics Time Machine Storage (module name: `TimeMachineStorage`)
+3. Media Metrics Transaction Log (module name: `TransactionLog`)
+4. Media Metrics Analytics Action (module name: `AnalyticsAction`)
+5. Media Metrics Audio Analytics (module name: `AudioAnalytics`)
+6. Media Metrics Timed Action (module name: `TimedAction`)
+
+| Module| Valid Input Values| Configured Value|
+|------------- |-------------| ----- |
+| `Item` | Key: `std::string`. Values: `INT32_MIN` to `INT32_MAX`, `INT64_MIN` to `INT64_MAX`, `std::string`, `double`, `pair<INT32_MIN to INT32_MAX, INT32_MIN to INT32_MAX>` | Value obtained from FuzzedDataProvider |
+| `TimeMachineStorage`   | Key: `std::string`. Values: `INT32_MIN` to `INT32_MAX`, `INT64_MIN` to `INT64_MAX`, `std::string`, `double`, `pair<INT32_MIN to INT32_MAX, INT32_MIN to INT32_MAX>` | Value obtained from FuzzedDataProvider |
+| `TranscationLog`   | `mediametrics::Item` | `mediametrics::Item` created by obtaining values from FuzzedDataProvider|
+| `AnalyticsAction`   | URL: `std::string` ending with .event, Value: `std::string`, action: A function | URL and Values obtained from FuzzedDataProvider, a placeholder function was passed as action|
+| `AudioAnalytics`   | `mediametrics::Item` | `mediametrics::Item` created by obtaining values from FuzzedDataProvider|
+| `TimedAction`   | time: `std::chrono::seconds`, function: `std::function` | `std::chrono::seconds` : value obtained from FuzzedDataProvider, `std::function`: a placeholder function was used. |
+
+This also ensures that the plugin is always deterministic for any given input.
+
+## Build
+
+This describes steps to build mediametrics_service_fuzzer binary.
+
+### Android
+
+#### Steps to build
+Build the fuzzer
+```
+  $ mm -j$(nproc) mediametrics_service_fuzzer
+```
+
+#### Steps to run
+Create a directory CORPUS_DIR and copy some files to that folder
+Push this directory to device.
+
+To run on device
+```
+  $ adb sync data
+  $ adb shell /data/fuzz/arm64/mediametrics_service_fuzzer/mediametrics_service_fuzzer CORPUS_DIR
+```
