# Build - Android There's also a quick and easy video on [YouTube](https://bit.ly/muly-youtube) on link that you can follow. ### Keep in mind 1. Throughout these steps, I will use **com.yourapp.android** as a placeholder for your app's package name that *you must replace* with yours. Open the **android** folder inside downloaded archive in Android Studio using **Open Existing Project** option on the launch screen. ### Refactor The very first thing is to rename the package from `ltd.starthub.muly` to yours e.g., `com.yourapp.android` everywhere. To do so, please follow below steps: 1. In the *Project* view on the left, click the **Gear** icon and make sure **Compact Middle Packages** is unchecked (turned off). 2. In the *Project* view, now expand `app > java` until you see `ltd` package. 3. **Right-click** on `ltd`, choose `Refactor > Rename` option and enter the replacement for `ltd` part i.e., `com` in our example case. Repeat this process to rename `starthub` to `yourapp` and `muly` to `android`. 4. From the Project view, open the file `build.gradle` from **Muly.app** module and replace `ltd.starthub.muly` with your package name e.g., `com.yourapp.android`. ### Firebase Copy the `google-services.json` file you downloaded above from from **Firebase** and paste it inside `app` folder. ### Configure Edit the `app/src/main/res/values/config.xml` file and update important values as mentioned below. 1. `facebook_app_id` = This must be set to app ID of your Facebook app configured earlier in this guide. 2. `facebook_protocol_scheme` = This should be the value of `facebook_app_id` set above with `fb` prefix e.g., `fb01234567890123456789`. 3. `facebook_client_token` = This should be as copied from Facebook for Developers console. 4. `google_client_id` = This is the (type `3`) client ID extracted from `google-services.json` file downloaded earlier. 5. `link_privacy_policy` = This is the URL to applicable *privacy policy* you may have created. 6. `link_terms_of_use` = This is the URL to applicable *terms of use* you may have created. 7. `server_api_key` = Set this to the API key shown by server at install time. If you missed to note it down, you can also find this anytime in the .env file on server as value of `API_KEY` variable. 8. `server_url` = This must be URL to your installation and `/api/` suffix e.g., `https://yourapp.com/api/`. 9. `sharing_links_domain` = This is the domain (URL prefix) you may have created in Firebase earlier in guide e.g., `yourapp.page.link`. 10. `support_*` = You can set these values to show links in Support section of Settings page. If you would like to hide any of those, just set them to empty values. 11. `location_api_key` = Set this to Android key we generated in Google Cloud Console for our Maps project. 12. `adcolony_app_id` = If you want to show ads from AdColony in your app, please set this value corresponding to the app you created in AdColony client area. 13. `admob_app_id` = If you want to show ads from AdMob in your app, please set the value to corresponding to the app in your AdMob account. ### Build Once configured as desired, you can build the project by using the `Build > Generate Signed Bundle / APK` option in Android Studio. Upon asked, please choose the keystore you created at the beginning of the guide and select `release` build type. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
