-Mobile Doc Translate Add-on
-===========================
-
-A sample Google Apps Script mobile add-on for Google Docs. This add-on is
-essentially a mobile version of the Docs
-[Translate Add-on Quickstart](https://developers.google.com/apps-script/quickstart/docs).
-
-Introduction
-------------
-
-Google Apps Script now allows developers to construct Mobile Add-ons -- Android
-applications which extend and support Google Docs and Sheets.
-
-This sample shows how to construct a mobile add-on called
-**Mobile Doc Translate**. This add-on allows users to select text in a
-Google Doc on their mobile device and see a translation of that text in one
-of several languages. The user can then edit the translation as needed and
-replace the original selected text in the Doc with the translation.
-
-
-Getting Started
----------------
-
-The add-on will need to call an Apps Script project to get Doc text, make
-translations, and insert text into the Doc. Users can access this add-on from
-the Google Docs Android app by highlighting text and selecting the add-on in the
-text context menu.
-
-The Apps Script code file for this project is `Code.gs`. This is the same code
-used in the [Translate Add-on Quickstart](https://developers.google.com/apps-script/quickstart/docs),
-but does not include the HTML code that defines the quickstart's sidebar.
-
-The mobile add-on will make use of the
-[Apps Script Execution API](https://developers.google.com/apps-script/guides/rest/)
-to call the `Code.gs` functions. The
-[Execution API quickstart for Android](https://developers.google.com/apps-script/guides/rest/quickstart/android)
-describes how to call Apps Script functions from Android applications.
-
-To build this sample:
-
-1. The `app/` folder in this repository contains all the required Android files
- for this add-on. These can be manually copied or imported into a new Android
- Studio project.
-1. Create a new Apps Script project.
-1. Replace the code in the new project's `Code.gs` file with the code from this
- repo.
-1. Save the project.
-1. In the code editor, select **Publish > Deploy as API** executable.
-1. In the dialog that opens, leave the **Version** as "New" and enter
- "Target-v1" into the text box. Click **Deploy**.
-1. Follow the
- [Keytool SHA1 Fingerprint](https://developers.google.com/apps-script/guides/rest/quickstart/android#step_1_acquire_a_sha1_fingerprint)
- instructions to acquire a SHA1 fingerprint for your project.
-1. Using that SHA code, follow the
- [Turn on the Execution API](https://developers.google.com/apps-script/guides/rest/quickstart/android#step_2_turn_on_the_api_name)
- instructions to enable the API for your script project and create OAuth
- credentials. Be sure to match the same package name used in your Android
- code.
-1. Edit the `MainActivity.java` file so that the `SCRIPT_ID` constant is set to
- your Apps Script project ID (in the script editor, select
- **File > Project properties**, and use the **Project key**).
-
- These steps should allow you to build the Android app and have it successfully
- call the Apps Script code. You can test it by:
-
- 1. Install the app on a test Android device.
- 1. Set the app as the debug app on the device by running this
- [ADB](https://developer.android.com/studio/command-line/adb.html)
- command:
- `$ adb shell am set-debug-app --persistent `
- 1. Open a docucment using the Google Docs app on the device.
- 1. Highlight some text in the doc and select the three-dot icon to open the
- context menu, and then select **Mobile Doc Translate**.

-
-To continue learning about mobile add-ons for Google Docs and Sheets,
-take a look at the following resources:
-
-* [Mobile Add-ons](https://developers.google.com/apps-script/add-ons/mobile)
-* [Apps Script Execution API](https://developers.google.com/apps-script/guides/)
-
-Support

-For general Apps Script support, check the following:
-
-- Stack Overflow Tag: [google-apps-script](http://stackoverflow.com/questions/tagged/google-apps-script)
-- Issue Tracker: [google-apps-script-issues](https://code.google.com/p/google-apps-script-issues/issues/list)

-
-Patches are encouraged, and may be submitted by forking this project and
-submitting a pull request through GitHub.
