Emoji2 Emojipicker Version 1.0

Version 1.5.0

September 4, 2024

androidx.emoji2:emoji2-*:1.5.0 is released. Version 1.5.0 contains these commits.

Important changes since 1.4.0

  • Support emoji 15.1 and bidirectional emoji selector UI. A simple click on the bidirectional switcher allows users to toggle between left- and right-facing versions of emojis.
  • Support multi-skintone emoji selector. Long-pressing couple emojis reveals a multi-person emoji selector for the zero state. When the user taps on the left half of an emoji, the emoji preview on the bottom right will be updated accordingly. When the user selects both halves of an emoji, the emoji preview on the bottom right will show the entire emoji and the user can then input it.

New Features

androidx.emoji2:emoji2-emojipicker

The Emoji Picker is a UI solution that offers a modern look and feel, up-to-date emojis, and ease of use. Users can browse and select emojis and their variants, or choose from their recently used emojis. With this library, apps across different OEMs can provide an inclusive and unified emoji experience to their users without the developers having to build and maintain their own emoji picker from scratch.

Up-to-date Emojis

New emojis are released every year, and we will selectively include them in the Emoji Picker. To ensure backward compatibility, we perform an accurate emoji renderability check internally to eliminate tofu. This will ensure that the library is compatible across multiple Android versions and devices.

Sticky variants

Long-pressing an emoji will display a menu of variants, such as different genders or skin tones. The variant you choose will be saved in the emoji picker, and the last selected variant will be used in the main panel. With this feature, users can send their preferred emoji variants with just one tap.

Recent emoji

The RecentEmojiProvider is responsible for providing emojis in the “Recently Used” category. The library has a default recent emoji provider that satisfies the most common use case:

  • All selected emojis are saved per-app level in shared preferences.
  • The picker displays at most 3 rows of selected emojis, deduped, in reverse chronological order.

If this default behavior is sufficient, then you don't need to set the setRecentEmojiProvider() method.

Work with EmojiCompat

If the app has an EmojiCompat instance, it will be used in the emoji picker to render as many emojis as possible. If EmojiCompat is disabled, the emoji picker will still work fine.

How to use the library

To use the library, an app developer should

  1. Import androidx.emoji2:emojipicker:$version in build.gradle. 

    dependencies {
  implementation "androidx.emoji2:emojipicker:$version"
}

  2. Inflate the emoji picker view and optionally set emojiGridRows and emojiGridColumns based on the desired size of each emoji cell

    • You could leave them unset, the default is 9 emojiGridColumns, rows will be calculated based on the parent view height and emojiGridColumns
    • You could set emojiGridRows as a float to indicate there’s more emojis if scroll down in XML
     <androidx.emoji2.emojipicker.EmojiPickerView
  android:id="@+id/emoji_picker"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  app:emojiGridColumns="9" />

in code

    val emojiPickerView = EmojiPickerView(context).apply {
        emojiGridColumns = 15
        layoutParams = ViewGroup.LayoutParams(
            ViewGroup.LayoutParams.MATCH_PARENT,
            ViewGroup.LayoutParams.MATCH_PARENT
        )
    }
    findViewById<ViewGroup>(R.id.emoji_picker_layout).addView(emojiPickerView)

  1. Assuming you would like to append the selected emojis to a EditText, use setOnEmojiPickedListener()

      emojiPickerView.setOnEmojiPickedListener {
      findViewById<EditText>(R.id.edit_text).append(it.emoji)
  }

  2. Optionally set RecentEmojiProvider, see sample app for an example implementation.

  3. Optionally customize styles. Create your own style to override common theme attributes and apply the style to the EmojiPickerView. For example, overriding colorControlNormal will change the category icon color. 

      <style name="CustomStyle" >
      <item name="colorControlNormal">#FFC0CB</item>
  </style>
  <androidx.emoji2.emojipicker.EmojiPickerView
      android:id="@+id/emoji_picker"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:theme="@style/CustomStyle"
      app:emojiGridColumns="9" />

See sample app for an example implementation.

A full API surface can be found here.

Sample App

This sample app demonstrate basic use cases plus the following additional scenarios:

  • The view re-layouted because emojiGridRows and emojiGridColumns were reseted.
  • The recent emoji provider is overridden to sort by frequency.
  • Style customization.

API Changes

The Emoji Picker library has been updated with the following new APIs:

  • The EmojiPickerView class, which provides up-to-date emojis in a vertical scrollable view with a clickable horizontal header.
  • The ability to set the number of columns and rows in the emoji picker grid via XML attributes emojiGridColumns and emojiGridRows or the setEmojiGridColumns() and setEmojiGridRows() methods.
  • The ability to set an emoji picked listener via the setOnEmojiPickedListener() method. The listener will be notified whenever the user clicks any emoji.
  • The ability to provide a recent emoji provider via the setRecentEmojiProvider() method. This is an optional function. If the recent emoji provider is not set, a default recent emoji provider will be used by the library. The default behavior is defined as follows:
    • All selected emojis will be saved per-app level in shared preferences.
    • The picker will display at most 3 rows of selected emojis, deduped, in reverse chronological order.
  • The EmojiViewItem class, which holds the displayed emoji and its emoji variants.
  • The RecentEmojiProvider interface, which can be implemented to provide a recent emoji list. The recentEmojiProvider is responsible for providing emojis in the “Recently Used” category.
  • The RecentEmojiAsyncProvider interface, which can be implemented to provide a recent emoji list. The RecentEmojiAsyncProvider is responsible for providing emojis in the “Recently Used” category. This interface is equivalent to RecentEmojiProvider that allows clients to override the getRecentEmojiListAsync() method to provide recent emojis.
  • The RecentEmojiProviderAdapter class, which is an adapter for the RecentEmojiAsyncProvider and implements RecentEmojiProvider.

Emoji2 Version 1.0.0-beta01

September 15, 2021

androidx.emoji2:emoji2-*:1.0.0-beta01 is released. Version 1.0.0-beta01 contains these commits.

API Changes

  • Added setLoadingExecutor to FontRequestEmojiCompatConfig, which replaces the previous API of setHandler. This API allows apps to configure FontRequestEmojiCompatConfig to use any background executor.

    This change is a breaking change from androidx.emoji:emoji, so setHandler is retained as a no-op Deprecated API to aid in migration. (I6cd48)

Version 1.0.0-alpha03

June 30, 2021

androidx.emoji2:emoji2-*:1.0.0-alpha03 is released. Version 1.0.0-alpha03 contains these commits.

New Features

This release is a bugfix and stabilization release.

  1. EmojiEditTextHelper now allows null to be passed as a KeyListener. This allows the platform behavior of allowing nulls to be applied to emoji supporting EditText implementations.
  2. When using EmojiCompatInitializer initial startup delay is improved to trigger after the first Activity resumes. This allows app startup to happen uncontended, and avoids loading the font for app starts that never show a UI. After a short delay, EmojiCompat will create a thread to load the emoji font.
  • A new dependency on androidx.lifecycle:lifecycle-process from androidx.emoji2:emoji2 is added to implement the delay. This will have negligible APK size impact for apps that already include lifecycle (such as apps with appcompat).

API Changes

  • Allow null KeyListener in AppCompatEditText. This reverses the non-null annotation that was added to AppCompatEditText in 1.4.0-alpha01 and restores the previous behavior when passed null. (I21482, b/189559345)

Bug Fixes

  • Change EmojiCompatInitializer to delay font loading until 500ms after the first Activity.onResume. This allows an activity to perform Application.onCreate and Activity.onCreate uncontended, while still ensuring that the emoji font is loaded shortly after app startup. (I4bff7)

Version 1.0.0-alpha01

May 18, 2021

androidx.emoji2:emoji2:1.0.0-alpha01, androidx.emoji2:emoji2-views:1.0.0-alpha01, and androidx.emoji2:emoji2-views-helper:1.0.0-alpha01 are released. Version 1.0.0-alpha01 contains these commits.

Features in this initial release

Integrating emojicompat is recommended for all apps to support modern emoji from API19. All user generated content in your app contains 🎉.

EmojiCompat has moved from the androidx.emoji artifacts to the new androidx.emoji2, now in alpha01. The new artifacts replace the previous version.

emoji2 is added as a dependency to AppCompat starting in AppCompat 1.4.0-alpha01 and is enabled by default for AppCompat views.

The emoji2 artifact introduces a new automatic configuration using the androidx.startup library. You no longer need to write any 👨🏽‍💻 code to display 🐻‍❄️.

Changes in emoji2 from emoji

  • Added new automatic configuration EmojiCompatInitializer using androidx.startup.
  • Added new default configuration that uses service location to find a downloadable fonts provider in DefaultEmojiCompatConfiguration.
  • Classes moved from androidx.emoji package to androidx.emoji2.
  • Split EmojiTextView and related views to a separate artifact emoji2-views. This should only be used if your app doesn't use appcompat.
  • Extracted helpers for integrating emojicompat into custom views into a separate artifact emoji2-views-helper.
  • Added nullability annotations.
  • Helpers in emoji2-views-helper may now be used even when EmojiCompat is not initialized (previously they threw an exception).

What dependency should you add?

  • Apps with AppCompat should upgrade to appcompat version AppCompat 1.4.0-alpha01 or higher.
  • Apps without AppCompat using TextView/EditText from platform should use EmojiTextView and related classes from emoji2-views.

How to support in custom views

  • Apps with AppCompat should extend AppCompatTextView, AppCompatButton, etc. instead of platform TextView, etc.
  • Apps without AppCompat should add androidx.emoji2:emoji2-views-helper dependency and use helpers to integrate with custom TextView or EditText subclasses.

Configuring automatic initialization

  • Apps can disable the automatic initialization by adding this to the manifest:

     <provider
     android:name="androidx.startup.InitializationProvider"
     android:authorities="${applicationId}.androidx-startup"
     android:exported="false"
     tools:node="merge">
     <meta-data android:name="androidx.emoji2.text.EmojiCompatInitializer"
               tools:node="remove" />
 </provider>

  • This disables automatic configuration, and you can then pass a custom configuration to EmojiCompat.init. The default configuration for the system may be retrieved DefaultEmojiCompatConfig.create(context) for further configuration before passing to EmojiCompat.init.
