     34 
     35 2.2 By clicking to accept and/or using the Preview, you hereby agree to the terms of the License Agreement.
     36 
     37 2.3 You may not use the Preview and may not accept the License Agreement if you are a person barred from receiving the Preview under the laws of the United States or other countries including the country in which you are resident or from which you use the Preview.
     38

     40 
     41 3. Preview License from Google
     42 
     43 3.1 Subject to the terms of this License Agreement, Google grants you a limited, worldwide, royalty-free, non-assignable, non-exclusive, and non-sublicensable license to use the Preview solely to develop applications for compatible implementations of Android.
     44 
     45 3.2 You may not use this Preview to develop applications for other platforms (including non-compatible implementations of Android) or to develop another SDK. You are of course free to develop applications for other platforms, including non-compatible implementations of Android, provided that this Preview is not used for that purpose.
     46 
     47 3.3 You agree that Google or third parties owns all legal right, title and interest in and to the Preview, including any Intellectual Property Rights that subsist in the Preview. "Intellectual Property Rights" means any and all rights under patent law, copyright law, trade secret law, trademark law, and any and all other proprietary rights. Google reserves all rights not expressly granted to you.
     48 
     49 3.4 You may not use the Preview for any purpose not expressly permitted by the License Agreement. Except to the extent required by applicable third party licenses, you may not: (a) copy (except for backup purposes), modify, adapt, redistribute, decompile, reverse engineer, disassemble, or create derivative works of the Preview or any part of the Preview; or (b) load any part of the Preview onto a mobile handset or any other hardware device except a personal computer, combine any part of the Preview with other software, or distribute any software or device incorporating a part of the Preview.
     50 
     51 3.5 Use, reproduction and distribution of components of the Preview licensed under an open source software license are governed solely by the terms of that open source software license and not the License Agreement. You agree to remain a licensee in good standing in regard to such open source software licenses under all the rights granted and to refrain from any actions that may terminate, suspend, or breach such rights.
     52 
     53 3.6 You agree that the form and nature of the Preview that Google provides may change without prior notice to you and that future versions of the Preview may be incompatible with applications developed on previous versions of the Preview. You agree that Google may stop (permanently or temporarily) providing the Preview (or any features within the Preview) to you or to users generally at Google's sole discretion, without prior notice to you.
     54 
     55 3.7 Nothing in the License Agreement gives you a right to use any of Google's trade names, trademarks, service marks, logos, domain names, or other distinctive brand features.
     56 
     57 3.8 You agree that you will not remove, obscure, or alter any proprietary rights notices (including copyright and trademark notices) that may be affixed to or contained within the Preview.
     58 
     59 4. Use of the Preview by You
     60 
     61 4.1 Google agrees that nothing in the License Agreement gives Google any right, title or interest from you (or your licensors) under the License Agreement in or to any software applications that you develop using the Preview, including any intellectual property rights that subsist in those applications.
     62 
     63 4.2 You agree to use the Preview and write applications only for purposes that are permitted by (a) the License Agreement, and (b) any applicable law, regulation or generally accepted practices or guidelines in the relevant jurisdictions (including any laws regarding the export of data or software to and from the United States or other relevant countries).
     64 
     65 4.3 You agree that if you use the Preview to develop applications, you will protect the privacy and legal rights of users. If users provide you with user names, passwords, or other login information or personal information, you must make the users aware that the information will be available to your application, and you must provide legally adequate privacy notice and protection for those users. If your application stores personal or sensitive information provided by users, it must do so securely. If users provide you with Google Account information, your application may only use that information to access the user's Google Account when, and for the limited purposes for which, each user has given you permission to do so.
     66 
     67 4.4 You agree that you will not engage in any activity with the Preview, including the development or distribution of an application, that interferes with, disrupts, damages, or accesses in an unauthorized manner the servers, networks, or other properties or services of Google or any third party.
     68 
     69 4.5 You agree that you are solely responsible for (and that Google has no responsibility to you or to any third party for) any data, content, or resources that you create, transmit or display through Android and/or applications for Android, and for the consequences of your actions (including any loss or damage which Google may suffer) by doing so.
     70 
     71 4.6 You agree that you are solely responsible for (and that Google has no responsibility to you or to any third party for) any breach of your obligations under the License Agreement, any applicable third party contract or Terms of Service, or any applicable law or regulation, and for the consequences (including any loss or damage which Google or any third party may suffer) of any such breach.
     72 
     73 4.7 The Preview is in development, and your testing and feedback are an important part of the development process. By using the Preview, you acknowledge that implementation of some features are still under development and that you should not rely on the Preview having the full functionality of a stable release. You agree not to publicly distribute or ship any application using this Preview as this Preview will no longer be supported after the official Android SDK is released.
     74 
     75 5. Your Developer Credentials
     76 
     77 5.1 You agree that you are responsible for maintaining the confidentiality of any developer credentials that may be issued to you by Google or which you may choose yourself and that you will be solely responsible for all applications that are developed under your developer credentials.
     78 
     79 6. Privacy and Information
     80 
     81 6.1 In order to continually innovate and improve the Preview, Google may collect certain usage statistics from the software including but not limited to a unique identifier, associated IP address, version number of the software, and information on which tools and/or services in the Preview are being used and how they are being used. Before any of this information is collected, the Preview will notify you and seek your consent. If you withhold consent, the information will not be collected.
     82 
     83 6.2 The data collected is examined in the aggregate to improve the Preview and is maintained in accordance with Google's Privacy Policy located at http://www.google.com/policies/privacy/.
     84 
     85 7. Third Party Applications
     86 
     87 7.1 If you use the Preview to run applications developed by a third party or that access data, content or resources provided by a third party, you agree that Google is not responsible for those applications, data, content, or resources. You understand that all data, content or resources which you may access through such third party applications are the sole responsibility of the person from which they originated and that Google is not liable for any loss or damage that you may experience as a result of the use or access of any of those third party applications, data, content, or resources.
     88 
     89 7.2 You should be aware the data, content, and resources presented to you through such a third party application may be protected by intellectual property rights which are owned by the providers (or by other persons or companies on their behalf). You may not modify, rent, lease, loan, sell, distribute or create derivative works based on these data, content, or resources (either in whole or in part) unless you have been specifically given permission to do so by the relevant owners.
     90 
     91 7.3 You acknowledge that your use of such third party applications, data, content, or resources may be subject to separate terms between you and the relevant third party.
     92 
     93 8. Using Google APIs
     94 
     95 8.1 Google APIs
     96 
     97 8.1.1 If you use any API to retrieve data from Google, you acknowledge that the data may be protected by intellectual property rights which are owned by Google or those parties that provide the data (or by other persons or companies on their behalf). Your use of any such API may be subject to additional Terms of Service. You may not modify, rent, lease, loan, sell, distribute or create derivative works based on this data (either in whole or in part) unless allowed by the relevant Terms of Service.
     98 
     99 8.1.2 If you use any API to retrieve a user's data from Google, you acknowledge and agree that you shall retrieve data only with the user's explicit consent and only when, and for the limited purposes for which, the user has given you permission to do so.
    100 
    101 9. Terminating the License Agreement
    102

    106 
    107 9.3 Google may at any time, terminate the License Agreement, with or without cause, upon notice to you.
    108 
    109 9.4 The License Agreement will automatically terminate without notice or other action upon the earlier of:

    111 (B) Google issues a final release version of the Android SDK.
    112 
    113 9.5 When the License Agreement is terminated, the license granted to you in the License Agreement will terminate, you will immediately cease all use of the Preview, and the provisions of paragraphs 10, 11, 12 and 14 shall survive indefinitely.
    114

    120 
    121 10.3 GOOGLE FURTHER EXPRESSLY DISCLAIMS ALL WARRANTIES AND CONDITIONS OF ANY KIND, WHETHER EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO THE IMPLIED WARRANTIES AND CONDITIONS OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT.

    130 
    131 13. Changes to the License Agreement

    134 
    135 14. General Legal Terms
    136 
    137 14.1 the License Agreement constitutes the whole legal agreement between you and Google and governs your use of the Preview (excluding any services which Google may provide to you under a separate written agreement), and completely replaces any prior agreements between you and Google in relation to the Preview.
    138 
    139 14.2 You agree that if Google does not exercise or enforce any legal right or remedy which is contained in the License Agreement (or which Google has the benefit of under any applicable law), this will not be taken to be a formal waiver of Google's rights and that those rights or remedies will still be available to Google.
    140 
    141 14.3 If any court of law, having the jurisdiction to decide on this matter, rules that any provision of the License Agreement is invalid, then that provision will be removed from the License Agreement without affecting the rest of the License Agreement.

    143 14.4 You acknowledge and agree that each member of the group of companies of which Google is the parent shall be third party beneficiaries to the License Agreement and that such other companies shall be entitled to directly enforce, and rely upon, any provision of the License Agreement that confers a benefit on (or rights in favor of) them. Other than this, no other person or company shall be third party beneficiaries to the License Agreement.
    144 
    145 14.5 EXPORT RESTRICTIONS. THE PREVIEW IS SUBJECT TO UNITED STATES EXPORT LAWS AND REGULATIONS. YOU MUST COMPLY WITH ALL DOMESTIC AND INTERNATIONAL EXPORT LAWS AND REGULATIONS THAT APPLY TO THE PREVIEW. THESE LAWS INCLUDE RESTRICTIONS ON DESTINATIONS, END USERS AND END USE.

You and Google agree to submit to the exclusive jurisdiction of the courts located within the county of Santa Clara, California to resolve any legal matter arising from the License Agreement. Notwithstanding this, you agree that Google shall still be allowed to apply for injunctive remedies (or an equivalent type of urgent legal relief) in any jurisdiction.

    183       You can run and test your app with the Android Wear 2.0 Developer Preview
    184       in either of these ways:
    185     </p>
    186 
    187     <ul>
    188       <li>Install Android Wear 2.0 on a supported watch, or
    189       </li>
    190 
    191       <li>Set up an emulator that is running Android Wear 2.0
    192       </li>
    193     </ul>
    194 
    195     <p>
    196       If you want an environment for basic compatibility
    197       testing of your app, you can use your current APK and a
    198       supported watch or an emulator. As described below, you don't necessarily
    199       need to update your full development environment to do basic testing.
    200     </p>
    201 
    202     <p>
    203       However, if you want to modify your app to target
    204       Android Wear 2.0 or use new APIs, you need to update your development
    205       environment. See <a href="{@docRoot}wear/preview/start.html">Get Started
    206       with the Preview</a>.

    214       You can download a system image and manually flash it to a matching

    217     </p>
    218

    220       Manually flashing a watch is useful if you need precise control over the

    326       The steps for flashing an image to a watch are similar to the <a href=

    330       specific watch that matches the image (e.g., you must
    331       use an LGE Watch Urbane 2nd Edition for the corresponding image).

    373       To flash a device using one of the <a href=
    374       "#preview_system_images">system images</a>, confirm that you have the
    375       <code>fastboot</code> tool in the <code>platform-tools/</code> directory
    376       of the <a href="https://developer.android.com/sdk">Android SDK</a>. Be
    377       sure that you have the latest version of the <strong>Android SDK
    378       Platform-tools</strong> from the <a href=

    380     </p>
    381 
    382     <p>
    383       After you confirm that you have the <code>fastboot</code> tool, add the
    384       tool to your PATH environment variable so the tool can be found when you
    385       flash the watch.

    391 
    392     <p>
    393       To download a preview image and flash it to the watch:
    394     </p>
    395 
    396     <ol>
    397       <li>Download and unzip the appropriate system image from a "Preview

    399       above</a>.
    400       </li>
    401 
    402       <li>Attach the watch charger to the watch and plug the USB cord (from the
    403       charger) into your computer.
    404       </li>
    405 
    406       <li>Use the following <a href="{@docRoot}tools/help/adb.html">adb
    407       command</a> to confirm that the watch is available for flashing:
    408       <code>adb devices</code>
    409       </li>
    410 
    411       <li>Use the following adb command to start the device in fastboot mode:
    412       <code>adb reboot bootloader</code>
    413       </li>
    414 
    415       <li>If necessary, use one of following two commands to
    416       unlock the device's bootloader. This step erases all data on the
    417       device: <code>fastboot flashing unlock</code> or, for some
    418       devices, <code>fastboot oem unlock</code>
    419       </li>
    420 
    421       <li>On the watch, select the <strong>Unlock</strong> option.
    422       </li>
    423 
    424       <li>Navigate to the directory where you unzipped the system image in Step
    425       1. At the top level of that directory,
    426       execute the <code>flash-all</code> script by typing
    427       <code>flash-all.sh</code> or, in the case of Windows,
    428       <code>flash-all.bat</code>. The following may need to
    429       precede the command: <code>./</code>
