Users who download and install your sticker app will be able to add your stickers to their WhatsApp sticker picker/tray, and start sending those stickers from within WhatsApp. A separate app is necessary and it will reside on your phone's home screen just like any other app. Stickers on WhatsApp must be legal, authorized, and acceptable. Learn more about acceptable use of our services at https://www.whatsapp.com/legal/#terms-of-service. + +The sample code provides a simple way for you to drop in your sticker art and build an Android app with minimal development or coding experience needed. For advanced developers looking to make richer sticker apps, refer to the section [Advanced Development](#advanced-development) below. + +We recommend you create a version of your sticker app for iOS as well to give users of WhatsApp on iOS an opportunity to download your sticker app as well. +## Sticker art and app requirements +We recommend you refer to the FAQ at https://faq.whatsapp.com/general/26000226 for complete details on how to properly create your sticker art. This FAQ also contains a sample PSD that demonstrates best practices for composing legible, rich sticker art. + +* A sticker is an image that has a transparent background and can be sent in a + WhatsApp chat +* Stickers are organized into "packs". Your app can contain anywhere from 1 to + 10 packs. Users must explicitly add each pack to WhatsApp one-by-one, so your + app should list each pack separately and each pack must have its own + affordance to add it to WhatsApp (do not try to create "add all packs" + operations). +* Each sticker pack must have a minimum of 3 stickers and a maximum of 30 + stickers +* Stickers must be exactly 512 x 512 pixels +* Stickers will render on a variety of backgrounds, white, black, colored, patterned, etc. Test your sticker art on a variety of backgrounds. For this reason, we recommend you add a 8px #FFFFFF stroke to the outside of each sticker. See the sample PSD referenced at https://faq.whatsapp.com/general/26000226 for more details. +* Stickers must be in the [WebP format](https://developers.google.com/speed/webp). Currently, animated WebP or animated stickers are not supported. See the section [Converting to WebP](#converting-to-webp) below for information on how to create WebP files. +* Each sticker must be less than 100KB. See the section [Tips for Reducing File Size](#tips-for-reducing-file-size) below. +* Sticker Picker/Tray Icon + * Provide an image that will be used to represent your sticker pack in the WhatsApp sticker picker/tray + * This image should be 96 x 96 pixels + * Max file size of 50KB + +### Tips for reducing file size +We recommend reducing the size of each of your stickers. For reference, many of the stickers provided within WhatsApp are around 15KB each. The smaller your stickers, the faster they will send and the less data your users will have to spend sending them or downloading your app. Depending on your art and the type of graphics you've created, one of these two methods may result in smaller file sizes so we recommend experimenting with both. + +* The first method involves optimizing your PNGs using a PNG optimizer tool. If you're on MacOS, use https://pngmini.com. We recommend using Median Cut and adjusting the colors bar to reduce the size. If you're on Windows, use https://nukesaq88.github.io/Pngyu to optimize your PNGs. Then, convert them to WebP using the methods described in the [Converting to WebP](#converting-to-webp) section. +* The second method involves saving or converting your stickers as WebP while experimenting with the WebP export settings trying to optimize the images. You should try setting the quality of your WebP output to something lower than 100% and experiment with a quality level that gets you the smallest file size possible without noticeable image degradation. Each of the methods described in [Converting to WebP](#converting-to-webp) for exporting your files to WebP offer ways to control your resolution. + +### Converting to WebP +Your sticker art must be in the WebP format. We recommend using the tools you're most comfortable with to draw and compose your art, and converting them to WebP using one of a few different tools: + +* Sketch for Mac lets you export files as WebP. Open your sticker art file in Sketch, select a layer, multiple layers, or an artboard, and select Make Exportable in the bottom right. Pick your format as WebP, select Export, and then select the quality/resolution. +* [Android Studio](https://developer.android.com/studio/) allows you to convert PNGs to WebP. Simply create a new project in Android Studio, open your PNG and right click on the image and select convert to WebP ([https://developer.android.com/studio/write/convert-webp](https://developer.android.com/studio/write/convert-webp)). Make sure you uncheck the box next to "Skip images with transparency/alpha channel" in the export flow. +* You can install a [plugin](https://github.com/fnordware/AdobeWebM#download) for Photoshop that converts to WebP +* Use [cwebp](https://developers.google.com/speed/webp/), a command line tool + +## How to create a sticker app + +### Overview +If you would like to create a sticker app using the sample app, you only have to minimally modify the sample app to get up and running quickly. + +* After downloading this repo, open the entire folder for the sample app in [Android Studio](https://developer.android.com/studio/). If you are new to Android development, visit https://developer.android.com/training/basics/firstapp/index.html for more information on setting up your Android development environment. +* Navigate to SampleStickerApp/app/src/main/assets in Android Studio. +* Inside the assets folder, folder 1 contains a number of sample sticker art files. Replace these with your own sticker files. +* Also replace the sample tray icon PNG with your own tray icon. +* If you'd like to have more than 1 sticker pack in your app, simply create a folder named "2" or "3", etc. within the assets folder and place your art and tray icon in there. + +### Modifying the contents.json file +You must also modify the contents.json file in SampleStickerApp/app/src/main/assets. Replace the values of the metadata with your own. A few notes: + +* `name`: the sticker pack's name (128 characters max) +* `identifier`: The identifier should be unique and can be alphanumeric: a-z, A-Z, 0-9, and the following characters are also allowed "_", "-", "." and " ". The identifier should be less than 128 characters. +* `publisher`: name of the publisher of the pack (128 characters max) +* Replace the "image_file" value with the file name of your sticker image. It must have both the file name and extension. The ordering of the files in the JSON will dictate the ordering of your stickers in your pack. +* `android_play_store_link` and `ios_app_store_link` (optional fields): here you can put the URL to your sticker app in the Google Play Store and Apple App Store (if you have an iOS version of your sticker app). If you provide these URLs, users who receive a sticker from your app in WhatsApp can tap on it to view your sticker app in the respective App Stores. On Android, the URL follows the format https://play.google.com/store/apps/details?id=com.example where "com.example" is your app's package name. +* `emoji` (optional): add up to a maximum of three emoji for each sticker file. Select emoji that best describe or represent that sticker file. For example, if the sticker is portraying love, you may choose to add a heart emoji like 💕. If your sticker portrays pizza, you may want to add the pizza slice emoji 🍕. In the future, WhatsApp will support a search function for stickers and tagging your sticker files with emoji will enable that. The sticker picker/tray in WhatsApp today already categorizes stickers into emotion categories (love, happy, sad, and angry) and it does this based on the emoji you tag your stickers with. + +The following fields are optional: `ios_app_store_link`, `android_app_store_link`, `publisher_website`, `privacy_policy_website`, `license_agreement_website`, `emoji` + +If your app has more than 1 sticker pack, you will need to reference it in contents.json. Simply create a second array within the "sticker_packs" section of the JSON and include all the metadata (name, identifier, etc) along with all the references to the sticker files. + +### Build the sample app +Before building your app, you will need to do the following: + +* Make sure to change the app's icon (i.e. launcher icon) that will be displayed on the home screens of users who install your app. The icons are contained in SampleStickerApp/app/src/main/res in each of the folders beginning with mipmap (e.g. mipmap-xhdpi or mipmap-xxxhdpi). For a simple way to create these icons, you can use Android Image Asset Studio which is built into Android Studio. See https://developer.android.com/studio/write/image-asset-studio#access for more information on how to run this tool and read the section [here](https://developer.android.com/studio/write/image-asset-studio#create-adaptive) for information on how to use the tool to create your app's launcher icons. +* Change your apps name in strings.xml (SampleStickerApp/app/src/main/res/values/strings.xml). This is the name users will see for your app on their phone. +* In addition, the application id (e.g. com.whatsapp) need to be changed. Note that you need to specify a unique application id that does not exist in play store. For more information on how to set your application ID, visit https://developer.android.com/studio/build/application-id. +* Change the applicationId in build.gradle (SampleStickerApp/app/build.gradle) +* For developers that are familiar with package name, you can change the package name, but it is not required. The package name will not be visible once the app is built. + +Make sure to run and test your sticker app. For help on building your app, visit https://developer.android.com/studio/run/. The app will run some checks. If there are problems, you will see the error in [logcat](https://developer.android.com/studio/debug/am-logcat.html). If there are no errors, the app will launch successfully displaying the sticker packs you have included. + +## Submit your app +You need to build a release version of your app for submission to the Google Play Store. Click Build > Generate Signed Bundle/APK. For more information, visit https://developer.android.com/studio/publish/app-signing#sign-apk. Note that Android Studio saves the APKs you build in project-name/module-name/build/outputs/apk. For more information on building your app, visit https://developer.android.com/studio/run/. + +Importantly, when naming your app, it is strongly advised you do *not* use "WhatsApp" anywhere in the name of your app or in the name field of your app listing on the Google Play Store. However, when preparing your app for submission in Google Play Store, you'll have the option to add description associated with your app and it's okay to mention WhatsApp in the description. WhatsApp can also launch the Google Play Store and perform a search for other sticker pack apps. To help your app appear in this list, also add the keyword WAStickerApps to app's description when setting up your app in the Google Play Store console. You can use additional keywords, but make sure you at least use this one. + +To submit your app to the Google Play Store, follow the instructions here: https://developer.android.com/distribute/best-practices/launch/. + +## Advanced development +For advanced developers looking to make richer sticker apps, follow the instructions below. + +### Overview + +Sticker apps communicate with WhatsApp as follows: + +* Your app should provide a `ContentProvider` (the sample app provides an example) to share the sticker pack information to WhatsApp. The `ContentProvider` shares information about the sticker pack's name, publisher, identifier and everything else that is listed in `contents.json` file. It also allows WhatsApp to fetch actual sticker files from the `ContentProvider`. The `ContentProvider` is identified by its authority. And a sticker pack is identified by the combination of the authority and identifier. +* Your app should send an intent to launch WhatsApp's activity. The intent contains three pieces of information: the `ContentProvider` authority, the pack identifier of the pack that user wants to add, and the sticker pack name. Once the user confirms that they want to add that sticker pack to WhatsApp, WhatsApp will remember the pair of authority and identifier and will load the pack's stickers in the WhatsApp sticker picker/tray. + +### ContentProvider +The ContentProvider in the sample app is [StickerContentProvider](app/src/main/java/com/example/samplestickerapp/StickerContentProvider.java). The ContentProvider provides 4 APIs: + +1. `/metadata`, this returns information about all the sticker packs in your app. Replace `` with the actual authority string. In the sample app, it is `com.geekofia.whatsappstickers.stickercontentprovider` +2. `/metadata/`, this returns information about a single pack. Replace `` with the actual identifier of the pack. In the sample app, it is `1`. +3. `/stickers/`, this returns information about the stickers in a pack. The returned information includes the sticker file name and emoji associated with the sticker. +4. `/stickers_asset//`, this returns the binary information of the sticker: `AssetFileDescriptor`, which points to the asset file for the sticker. Replace `` with the actual sticker file name that should be fetched. + +The ContentProvider needs to have a read permission of `com.whatsapp.sticker.READ` in `AndroidManifest.xml`. It also needs to be exported and enabled. See below for an example: + + +### Intent +It is required that users explicitly add a sticker pack to WhatsApp, so your app must provide a UI element to allow users to add a pack (for example, a button labeled "Add to WhatsApp" as in the sample app). +In the sample app, both [StickerPackListActivity](app/src/main/java/com/example/samplestickerapp/StickerPackListActivity.java) and [StickerPackDetailsActivity](app/src/main/java/com/example/samplestickerapp/StickerPackDetailsActivity.java) contains code to launch the intent after the user presses the Add to WhatsApp button. The user must then confirm they want to add the pack via the alert box presented by WhatsApp. + + Intent intent = new Intent(); + intent.setAction("com.whatsapp.intent.action.ENABLE_STICKER_PACK"); + intent.putExtra("sticker_pack_id", identifier); //identifier is the pack's identifier in contents.json file + intent.putExtra("sticker_pack_authority", authority); //authority is the ContentProvider's authority. In the case of the sample app it is BuildConfig.CONTENT_PROVIDER_AUTHORITY. + intent.putExtra("sticker_pack_name", stickerPackName); //stickerPackName is the name of the sticker pack. + try { + startActivityForResult(intent, 200); + } catch (ActivityNotFoundException e) { + Toast.makeText(this, R.string.error_adding_sticker_pack, Toast.LENGTH_LONG).show(); + } + +### Check if pack is added (optional) +Sticker apps can check to see if a sticker pack it provides has been added to WhatsApp by the user. This is useful if you'd like to display different UI to users. For example if the pack is not added, you should present a button to add it to WhatsApp, but if the pack is added, you can remove the add button and inform the user the pack is already added to WhatsApp. + +A `ContentProvider` provides information to sticker apps on whether an app is added to WhatsApp or not. This provider authority is `com.whatsapp.provider.sticker_whitelist_check` for the WhatsApp consumer app; `com.whatsapp.w4b.provider.sticker_whitelist_check` for the WhatsApp Business app. + +In order to query this ContentProvider, you need to provide the following query: +`content://com.whatsapp.provider.sticker_whitelist_check/is_whitelisted?authority='replace with authority of your sticker content provider'&identifier='replace with identifier of the pack'` + +The result is in a row corresponding to the column named `result`. The value will be either `0`, meaning the pack is not added to WhatsApp, or `1`, meaning the pack has been added. If the returned result is null, the query was invalid or the version of WhatsApp installed by the user is too old to support stickers. See the class in the sample app: [WhitelistCheck](app/src/main/java/com/example/samplestickerapp/WhitelistCheck.java). This class provides ways to do the query. You can call `WhitelistCheck.isWhitelisted(Context context, String identifier)`. The identifier should match the identifier of the pack you want to query. The authority is automatically filled in as the authority of your sticker app's ContentProvider. + +Note that a pack can be added to either the main WhatsApp app, WhatsApp Business, or both. It is recommended you continue to present a button to add the pack to WhatsApp if the sticker pack is not added to one or more of the apps. Refer to the class [WhitelistCheck](app/src/main/java/com/example/samplestickerapp/WhitelistCheck.java) for sample logic. + +Your app can only query whether the packs it provides have been added and it can't check for information about sticker packs from other apps. \ No newline at end of file diff --git a/app/.gitignore b/app/.gitignore new file mode 100644 index 0000000..796b96d --- /dev/null
