SDK Usage


To start using the MakemojiSDK you will first have to add a few lines to your Application class.

If you haven't already, declare an application class in your AndroidManifest.xml using it's fully qualified class name.


Then in App.java onCreate, setup your SDK key. Use the Google Advertising ID if you're using Makemoji for advertising and distributing to the Play Store.

    public void onCreate(){
        //Moji.setUserId("Google ad id here if needed"); // optional custom user id for analytics

Setup the Makemoji TextInput

First you will want to add the component to your activity content layout. Check out styles.xml for documentation on how to theme this view.


In your activity during onCreate, find the view you added in your layout, and have it handle the back button when it is expanded.

    MojiInputLayout mojiInputLayout;
    protected void onCreate(Bundle savedInstanceState) {
        mojiInputLayout = (MojiInputLayout)findViewById(R.id.mojiInput);

    public void onBackPressed(){
        if (mojiInputLayout.canHandleBack()){

        public void onMultiWindowModeChanged(boolean isInMultiWindowMode){

Send a Message

The SendLayoutClickListener will be called when a user clicks on the send button in the text input. This should be set in onCreate.

        mojiInputLayout.setSendLayoutClickListener(new MojiInputLayout.SendClickListener() {
            public boolean onClick(String html, Spanned spanned) {
                // send html to backend, display message
                return true;//true to clear the field, false to keep it

Camera Button

The CameraButtonClickListener is called when a user taps on the camera button in the text input

        mojiInputLayout.setCameraButtonClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                // handle camera click

Hypermoji - Emoji with a URL

To handle the display of a webpage when tapping on a Hypermoji ( an emoji with a URL link), use the HyperMojiClickListener callback.

        mojiInputLayout.setHyperMojiClickListener(new HyperMojiListener() {
            public void onClick(String url) {
				// handle opening URL

Displaying Messages

There are two key methods to use when displaying messages that are necessary for animation and Hypermoji click behavior.

Moji.setText(String html,TextView tv, boolean simple) parses the HTML and places it into a TextView, beginning any Hypermoji/gif animation of the new text and ending animation of any existing text. The "simple" argument ignores any other attributes like size or font. It should usually be set to true. See the plain text section below for instructions if not using HTML.

Set a global HyperMojiClickListener using Moji.setDefaultHyperMojiListener(...), or one on each TextView you use, like so

            textView.setTag(R.id._makemoji_hypermoji_listener_tag_id, new HyperMojiListener() {
                public void onClick(String url) {
                    Toast.makeText(getContext(),"hypermoji clicked from adapter url " + url,Toast.LENGTH_SHORT).show();

You can also use the parseHtml method to cache the results of parsing html for ListView performance, like in MAdapter

Detatched Input

To hide the built in Edit Text and use your own that is somewhere else on the screen as the input target, call attatchMojiEditText(MojiEditText outsideMojiEdit) on the MojiInputLayout. Call detachMojiEditText() to restore the default behavior. Note that attatchMojiEditText requires an EditText that is an instance of MojiEditText to ensure keyboard compatibility and correct copy paste functionality.

            String html = Moji.toHtml(outsideMojiEdit.getText());//to get input as html
            mojiInputLayout.manualSaveInputToRecentsAndBackend();//to send message to analytics console and emojis to user's recent list

Plain Text Converter

If you need to convert an html message to a platform that does not support Makemoji, you can use the plain text converter to produce a message with a human-friendly reading that converts emojis into the form [flashtagname.base62emojiid hypermojiurl]. For example, "Aliens are real [alien.gG iwanttobelieve.com]." It is recommended to store the html of the message as the canonical version, but you can also convert from plain text back to html if needed. Note the plain text format contains no sizing information unlike html. Therefore, if you are using the "large emoji sizing" that modifies the size of the first three emojis you will need to set a special text watcher as a tag on the textview to replicate this behavior. Make sure to null this tag if you call Moji.setText(...) with html later.

        mojiInputLayout.setSendLayoutClickListener(new MojiInputLayout.SendClickListener() {
            public boolean onClick(String html, Spanned spanned) {
                    String plainText = Moji.htmlToPlainText(html);
                    Spanned spanned = Moji.plainTextToSpanned(plainText);
                    textview.setTag(R.id._makemoji_text_watcher, Moji.getDefaultTextWatcher());

(Optional) Emoji Wall Selection Activity

The Emoji Wall is an activity that allows your users to select one emoji from the Makemoji library or the built in Android emoji. Declare it in your manifest to launch it. Alternatively, you can host the MojiWallFragment in your own activity that implements IMojiSelected.

            android:label="Emoji Wall Activity">
            Intent intent = new Intent(this, MojiWallActivity.class);
            //intent.putExtra(MojiWallActivity.EXTRA_THEME,R.style.MojiWallDefaultStyle_Light); //to theme it
            intent.putExtra(MojiWallActivity.EXTRA_SHOWRECENT,true);//show recently used emojis as a tab
            intent.putExtra(MojiWallActivity.EXTRA_SHOWUNICODE,true);//show unicode emojis as a tab

The result is returned as a json string that can be converted into a MojiModel containing the name, image url, and unicode character, if applicable.

     protected void onActivityResult(int requestCode, int resultCode, Intent data) {
         if (requestCode == IMojiSelected.REQUEST_MOJI_MODEL && resultCode== RESULT_OK){
                 String json = data.getStringExtra(Moji.EXTRA_JSON);
                 MojiModel model = MojiModel.fromJson(new JSONObject(json));
             catch (Exception e){

To theme the activity, pass the activity theme as an extra when starting the activity. Make sure it extends from AppCompat and includes the following attributes.

        <item name="_mm_wall_tab_layout">@layout/mm_wall_tab</item>
        <item name="_mm_wall_header_layout">@layout/mm_wall_header</item>
        <item name="_mm_wall_tabs_bg">@android:color/black</item>
        <item name="_mm_wall_pager_bg">@color/_mm_grey_900</item>

(Optional) Include the Third Party Keyboard IME!

You can package the Makemoji keyboard in your app so users can select it as a soft keyboard no matter what app they're in. Selecting an emoji here will cause the keyboard to launch a picture share intent to the current app, or copy the image url to the clipboard if there is no matching intent filter in the current app's manifest. Add the third party keyboard to your dependencies.

compile 'com.makemoji:makemoji-3pk-android:0.9.822'

In strings.xml, set the provider authority for the keyboards' content provider based on your unique package name, add the keyboard name as it will appear to the user and the class name of the keyboard's settings activity. Make sure to prompt the user to activate the keyboard after installation using code similar to ActivateActivity, or the keyboard won't show up as an option. If you are publishing multiple apps, each provider authority must be unique or there will be installation problems!

    <!-- strings.xml -->
    <string name="_mm_provider_authority">com.makemoji.keyboard.fileprovider</string>
    <string name="_mm_kb_label">MakeMoji Keyboard (Sample App)</string>
    <string name="_mm_kb_share_message">MakeMoji Keyboard (Sample App)</string> <!-- share button invisible if empty -->
    <string name="_mm_kb_settings_activity">com.makemoji.sbaar.mojilist.ActivateActivity</string>
    <!-- optional customization -->
    <color name="mmKBPageTitleColor">@color/colorPrimary</color>
    <color name="mmKBIconColor">@color/colorPrimary</color>
    <color name="mmKBProgressColor">@color/_mm_default_send_text_color</color>

    <integer name="mm_3pk_rows">5</integer>
    <integer name="mm_3pk_cols">8</integer>
    <integer name="mm_3pk_gif_rows">2</integer>

    <dimen name="mmKBMaxTabWidth">38dp</dimen>
    <dimen name="mmKBMaxTabSize">36dp</dimen>

    <!--Reuse bitmaps used for spans in textview; turn this off when using fewer rows/cols in 3pk -->
    <bool name="mmUseSpanSizeFor3pkImages">false</bool>
    <!-- replace kb_tab_bg.xml with a selector to change the keyboard tab background -->

If you want the ability to customize some other aspect of the sdk or 3pk, just ask.

(Optional) Control Locked Categories

If you choose to lock some of your categories, you can control which are unlocked for the device by using the MojiUnlock class. To listen for when a user clicks a locked category in the MojiInpuLayout, set a listener.

        mojiInputLayout.setLockedCategoryClicked(new MojiUnlock.ILockedCategoryClicked() {
            public void onClick(String name) {

If using the 3pk, you can either set a global listener for when a keybaord category is selected, or listen to the default intent fired when a locked category is clicked. Add an intent filter to activity to be launched for the action "com.makemoji.mojilib.action.LOCKED_CATEGORY_CLICKED".

        MMKB.setCategoryListener(new MMKB.ICategorySelected() {
            View v;
            public void categorySelected(String category,boolean locked, final FrameLayout parent) {
            //OR in an activity
            public void onNewIntent(Intent i){
                if (Moji.ACTION_LOCKED_CATEGORY_CLICK.equals(i.getAction())){

To customize the image overlaid onto a locked category icon, add mm_locked_foreground.xml to your drawable folder. It can look something like this

    <?xml version="1.0" encoding="utf-8"?>
    <bitmap  xmlns:android="http://schemas.android.com/apk/res/android"  android:src="@drawable/mm_placeholder"  android:alpha=".8" />

If you are using the Emoji Wall, extend MojiWallActivity to respond to a locked category being selected and launch this activity instead.

    public class MyMojiWallActivity extends MojiWallActivity{
        public void lockedCategoryClick(String name) {
            MojiUnlock.addGroup(name);//unlock the category
            fragment.refresh();//refresh the tabs

(Optional) Emoji reactions

To include a horizontal view of emoji reactions for a piece of content, include a ReactionsLayout with a given height, like 30dp.


You must set an id corresponding to a unique piece of your content on each reaction layout, using reactionsLayout.setReactionsData(new ReactionData(id)); Make sure to hold onto this data object if you wish to assign it to a view again, such as in a list adapter.

Each ReactionsLayout has an 'add' button that will open the MojiWallActivity for the user to select one, so make sure to add it to your manifest as described above. To update the ReactionsLayout with the user selection, add the following in your onActivityResult.

    protected void onActivityResult(int requestCode, int resultCode, Intent data) {

(Optional) Offline Mode

To package emojis with your app and have no online dependencies, run this script and place the output under res/assets/makemoji Then run the following code after initialisation.

    Moji.setEnableUpdates(false);//offline mode
    //call only first time or when new assets are in the app after an update

Proguard Setup

If you need to use proguard when signing your app, add the following to your proguard-rules.pro file

-keep class com.makemoji.** { *; }

-dontwarn okio.**
-dontwarn retrofit2.**
-dontwarn rx.**

-keepclasseswithmembers class * {
    @retrofit2.http.* <methods>;

-keepattributes Signature
-keepattributes Exceptions

-dontwarn android.app.Activity #If target sdk <24
