# Send A Message

Using CometChat, you can send three types of messages:

1. A [Text Message](/sdk/android/v5/send-message#text-message), the most common and standard message type.
2. A [Media Message](/sdk/android/v5/send-message#media-message), for sending photos, videos and files.
3. A [Custom Message](/sdk/android/v5/send-message#custom-message), for sending completely custom data using JSON structures.
4. A [Interactive Messages](/sdk/android/v5/interactive-messages), for sending end-user interactive messages of type form, card and custom Interactive

You can also send metadata along with a text or media message. Think, for example, if you'd want to share the user's location with every message, you can use the metadata field.

## Text Message

*In other words, as a sender, how do I send a text message?*

To send a text message to a single user or group, you need to use the `sendMessage()` method and pass a `TextMessage` object to it.

### Add Metadata

To send custom data along with a text message, you can use the `setMetadata` method and pass a `JSONObject` to it.

<Tabs>
  <Tab title="Java">
    ```java theme={null}
    JSONObject metadata = new JSONObject();
    metadata.put("latitude", "50.6192171633316");
    metadata.put("longitude", "-72.68182268750002");
    textMessage.setMetadata(metadata);
    ```
  </Tab>

  <Tab title="Kotlin">
    ```kotlin theme={null}
    val metadata = JSONObject()
    metadata.put("latitude", "50.6192171633316")
    metadata.put("longitude", "-72.68182268750002")
    textMessage.setMetadata(metadata)
    ```
  </Tab>
</Tabs>

### Add Tags

To add a tag to a message you can use the `setTags()` method of the TextMessage Class. The `setTags()` method accepts a list of tags.

<Tabs>
  <Tab title="Java">
    ```java theme={null}
    List<String> tags = new ArrayList<>();
    tags.add("pinned");
    textMessage.setTags(tags);
    ```
  </Tab>

  <Tab title="Kotlin">
    ```kotlin theme={null}
    val tags: MutableList<String> = ArrayList()
    tags.add("pinned")
    textMessage.setTags(tags)
    ```
  </Tab>
</Tabs>

### Set Quoted Message

To set a quoted message for a message, use the `setQuotedMessageId()` and `setQuotedMessage()` method of the TextMessage class. This method accepts the ID of the message to be quoted.

<Tabs>
  <Tab title="Java">
    ```java theme={null}
    textMessage.setQuotedMessageId(10);
    textMessage.setQuotedMessage(); // Pass base message object here that you want to quote.
    ```
  </Tab>

  <Tab title="Kotlin">
    ```kotlin theme={null}
    textMessage.quotedMessageId = 0
    textMessage.quotedMessage =  // Pass base message object here that you want to quote.
    ```
  </Tab>
</Tabs>

Once the text message object is ready, you need to use the `sendMessage()` method to send the text message to the recipient.

<Tabs>
  <Tab title="Java (User)">
    ```java theme={null}
    private String receiverID = "UID";
    private String messageText = "Hello CoemtChat!";
    private String receiverType = CometChatConstants.RECEIVER_TYPE_USER;

    TextMessage textMessage = new TextMessage(receiverID, messageText, receiverType);

    CometChat.sendMessage(textMessage, new CometChat.CallbackListener<TextMessage>() {
      @Override
      public void onSuccess(TextMessage textMessage) {
          Log.d(TAG, "Message sent successfully: " + textMessage.toString());
      }

      @Override
      public void onError(CometChatException e) {
          Log.d(TAG, "Message sending failed with exception: " + e.getMessage());
      }
    });
    ```
  </Tab>

  <Tab title="Kotlin (User)">
    ```kotlin theme={null}
    private val receiverID = "UID"
    private val messageText = "Hello CometChat!"
    private val receiverType = CometChatConstants.RECEIVER_TYPE_USER

    val textMessage = TextMessage(receiverID, messageText, receiverType)

    CometChat.sendMessage(textMessage, object : CallbackListener<TextMessage>() {
      override fun onSuccess(textMessage: TextMessage) {
          Log.d(TAG, "Message sent successfully: $textMessage")
      }

      override fun onError(e: CometChatException) {
          Log.d(TAG, "Message sending failed with exception: " + e.message)
      }
    })
    ```
  </Tab>

  <Tab title="Java (Group)">
    ```java theme={null}
    private String receiverID = "GUID";
    private String messageText = "Hello CometChat!";
    private String receiverType = CometChatConstants.RECEIVER_TYPE_GROUP;

    TextMessage textMessage = new TextMessage(receiverID, messageText, receiverType);

    CometChat.sendMessage(textMessage, new CometChat.CallbackListener<TextMessage>() {
      @Override
      public void onSuccess(TextMessage textMessage) {
          Log.d(TAG, "Message sent successfully: " + textMessage.toString());
      }

      @Override
      public void onError(CometChatException e) {
          Log.d(TAG, "Message sending failed with exception: " + e.getMessage());
      }
    });
    ```
  </Tab>

  <Tab title="Kotlin (Group)">
    ```kotlin theme={null}
    private val receiverID = "GUID"
    private val messageText = "Hello CometChat!"
    private val receiverType = CometChatConstants.RECEIVER_TYPE_GROUP

    val textMessage = TextMessage(receiverID, messageText, receiverType)
    CometChat.sendMessage(textMessage, object : CallbackListener<TextMessage>() {
      override fun onSuccess(textMessage: TextMessage) {
          Log.d(TAG, "Message sent successfully: $textMessage")
      }

      override fun onError(e: CometChatException) {
          Log.d(TAG, "Message sending failed with exception: " + e.message)
      }
    })
    ```
  </Tab>
</Tabs>

The `TextMessage` class constructor takes the following parameters:

| Parameter      | Description                                                                                                                  |          |
| -------------- | ---------------------------------------------------------------------------------------------------------------------------- | -------- |
| `receiverID`   | `UID` of the user or `GUID` of the group receiving the message                                                               | Required |
| `messageText`  | The text message                                                                                                             | Required |
| `receiverType` | The type of the receiver- `CometChatConstants.RECEIVER_TYPE_USER` (user) or `CometChatConstants.RECEIVER_TYPE_GROUP` (group) | Required |

When a text message is sent successfully, the response will include a `TextMessage` object which includes all information related to the sent message.

## Media Message

*In other words, as a sender, how do I send a media message like photos, videos & files?*

To send a media message to any user or group, you need to use the `sendMediaMessage()` method and pass a `MediaMessage` object to it.

### Add Metadata

To send custom data along with a media message, you can use the `setMetadata` method and pass a `JSONObject` to it.

<Tabs>
  <Tab title="Java">
    ```java theme={null}
    JSONObject metadata = new JSONObject();
    metadata.put("latitude", "50.6192171633316");
    metadata.put("longitude", "-72.68182268750002");
    mediaMessage.setMetadata(metadata);
    ```
  </Tab>

  <Tab title="Kotlin">
    ```kotlin theme={null}
    val metadata = JSONObject()
    metadata.put("latitude", "50.6192171633316")
    metadata.put("longitude", "-72.68182268750002")
    mediaMessage.setMetadata(metadata)
    ```
  </Tab>
</Tabs>

### Add Caption(Text along with Media Message)

To send a caption with a media message, you can use `setCaption` method and pass text to it.

<Tabs>
  <Tab title="Java">
    ```java theme={null}
    mediaMessage.setCaption("Message Caption");
    ```
  </Tab>

  <Tab title="Kotlin">
    ```kotlin theme={null}
    mediaMessage.setCaption("Message Caption")
    ```
  </Tab>
</Tabs>

### Add Tags

To add a tag to a message you can use the `setTags()` method of the MediaMessage Class. The `setTags()` method accepts a list of tags.

<Tabs>
  <Tab title="Java">
    ```java theme={null}
    List<String> tags = new ArrayList<>();
    tags.add("pinned");
    mediaMessage.setTags(tags);
    ```
  </Tab>

  <Tab title="Kotlin">
    ```kotlin theme={null}
    val tags: MutableList<String> = ArrayList()
    tags.add("pinned")
    mediaMessage.setTags(tags)
    ```
  </Tab>
</Tabs>

There are 2 ways you can send Media Messages using the CometChat SDK:

1. **By providing the File :** You can directly share the file object while creating an object of the MediaMessage class. When the media message is sent using the sendMediaMessage() method, this file is then uploaded to CometChat servers and the URL of the file is sent in the success response of the sendMediaMessage() function.

<Tabs>
  <Tab title="Java (User)">
    ```java theme={null}
    private String receiverID = "UID";
    private String messageType = CometChatConstants.MESSAGE_TYPE_IMAGE;
    private String receiverType = CometChatConstants.RECEIVER_TYPE_USER;
    private String filePath = "/storage/emulated/0/Download/CometChat.jpg";

    MediaMessage mediaMessage = new MediaMessage(receiverID, new File(filePath), messageType, receiverType);

    CometChat.sendMediaMessage(mediaMessage, new CometChat.CallbackListener<MediaMessage>() {
      @Override
      public void onSuccess(MediaMessage mediaMessage) {
          Log.d(TAG, "Media message sent successfully: " + mediaMessage.toString());
      }

      @Override
      public void onError(CometChatException e) {
          Log.d(TAG, "Media message sending failed with exception: " + e.getMessage());
      }
    });
    ```

    val mediaMessage = MediaMessage(receiverID, File(filePath), messageType, receiverType)
    CometChat.sendMediaMessage(mediaMessage, object : CallbackListener<MediaMessage>() {
      override fun onSuccess(mediaMessage: MediaMessage) {
          Log.d(TAG, "Media message sent successfully: " + mediaMessage.toString())
      }

      override fun onError(e: CometChatException) {
          Log.d(TAG, "Media message sending failed with exception: " + e.message)

The `MediaMessage` class constructor takes the following parameters:

| Parameter      | Description                                                                                                                                                                                                                                                                               |          |
| -------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------- |

2. **By providing the URL of the File:** The second way to send media messages using the CometChat SDK is to provide the SDK with the URL of any file that is hosted on your servers or any cloud storage. To achieve this you will have to make use of the Attachment class that is available in the MediaMessage class. For more information, you can refer to the below code snippet:

<Tabs>
  <Tab title="Java (User)">
    ```java theme={null}
    String receiverId = "recipient_UID";

    MediaMessage mediaMessage = new MediaMessage(receiverId, CometChatConstants.MESSAGE_TYPE_IMAGE, CometChatConstants.RECEIVER_TYPE_USER);

    Attachment attachment = new Attachment();
    attachment.setFileName("test");
    attachment.setFileExtension("png");
    attachment.setFileUrl("https://pngimg.com/uploads/mario/mario_PNG125.png");

    mediaMessage.setAttachment(attachment);

    CometChat.sendMediaMessage(mediaMessage, new CometChat.CallbackListener<MediaMessage>() {
      @Override
      public void onSuccess(MediaMessage mediaMessage1) {
          Log.i(TAG, "onSuccess");
      }

      @Override
      public void onError(CometChatException e) {
          Log.e(TAG, e.getMessage());
      }
    });
    ```
  </Tab>

  <Tab title="Kotlin (User)">

    attachment.fileName = "test"
    attachment.fileExtension = "png"
    attachment.fileUrl = "https://pngimg.com/uploads/mario/mario_PNG125.png"

    mediaMessage.attachment = attachment

    CometChat.sendMediaMessage(mediaMessage, object : CallbackListener<MediaMessage?>() {
      override fun onSuccess(mediaMessage1: MediaMessage?) {
          Log.i(TAG, "onSuccess")
      }

      override fun onError(e: CometChatException) {
          Log.e(TAG, e.message!!)
      }
    })
    ```
  </Tab>

    ```java theme={null}
    String receiverId = "recipient_GUID";

    MediaMessage mediaMessage = new MediaMessage(receiverId, CometChatConstants.MESSAGE_TYPE_IMAGE, CometChatConstants.RECEIVER_TYPE_GROUP);

    Attachment attachment = new Attachment();
    attachment.setFileName("test");
    attachment.setFileExtension("png");
    attachment.setFileUrl("https://pngimg.com/uploads/mario/mario_PNG125.png");

    mediaMessage.setAttachment(attachment);

    CometChat.sendMediaMessage(mediaMessage, new CometChat.CallbackListener<MediaMessage>() {
      @Override
      public void onSuccess(MediaMessage mediaMessage1) {
          Log.i(TAG, "onSuccess");
      }

      @Override
      public void onError(CometChatException e) {
          Log.e(TAG, e.getMessage());
      }
    });
    ```
  </Tab>

  <Tab title="Kotlin (Group)">
    ```kotlin theme={null}

    attachment.fileName = "test"
    attachment.fileExtension = "png"
    attachment.fileUrl = "https://pngimg.com/uploads/mario/mario_PNG125.png"

    mediaMessage.attachment = attachment

    CometChat.sendMediaMessage(mediaMessage, object : CallbackListener<MediaMessage?>() {
      override fun onSuccess(mediaMessage1: MediaMessage?) {
          Log.i(TAG, "onSuccess")
      }

      override fun onError(e: CometChatException) {
          Log.e(TAG, e.message!!)
      }
    })
    ```
  </Tab>
</Tabs>

When a media message is sent successfully, the response will include a `MediaMessage` object which includes all information related to the sent message.

If you wish to send a caption or some text along with the Media Message, you can use the `caption field` provided by the MediaMessage class. To set the caption you can use the `setCaption()` method and at the receiver end, you can obtain the caption using the `getCaption()` method. As with text messages, the metadata field can be used with media messages as well. Any additional information can be passed along with the media message as a `JSONObject`.

## Multiple Attachments in a Media Message

Starting version 3.0.9 & above the SDK supports sending of multiple attachments in a single media message. As in case for single attachment in a media message, there are two ways you can send Media Messages using the CometChat SDK:

1. **By providing an array of files:** You can now share a List of files while creating an object of the MediaMessage class. When the media message is sent using the `sendMediaMessage()` method, the files are uploaded to the CometChat servers & the URL of the files are sent in the success response of the `sendMediaMessage()` method.

    val mediaMessage = MediaMessage(groupId, files, fileType, CometChatConstants.RECEIVER_TYPE_GROUP)

    CometChat.sendMediaMessage(mediaMessage, object : CallbackListener<MediaMessage?>() {
      override fun onSuccess(mediaMessage: MediaMessage?) {
          Log.d(TAG, "Message Sent Successfully")

The `MediaMessage` class constructor takes the following parameters:

| **Parameter**    | **Description**                                                                                                                                                                                                                                                             |

| **receiverType** | The type of the receiver to whom the message is to be sent. <br />1. `CometChatConstants.RECEIVER_TYPE_USER` <br />2. `CometChatConstants.RECEIVER_TYPE_GROUP`                                                                                                              |

2. **By providing the URL of the multiple files:** The second way to send multiple attachments using the CometChat SDK is to provide the SDK with the URL of multiple files that is hosted on your servers or any cloud storage. To achieve this you will have to make use of the `Attachment` class. For more information, you can refer to the below code snippet:

    ```

When a media message is sent successfully, the response will include a `MediaMessage` object which includes all information related to the sent message.

You can use the `setMetadata()`, `setCaption()` & `setTags()` methods to add metadata, caption and tags respectively in exactly the same way as it is done while sending a single file or attachment in a Media Message.

## Custom Message

*In other words, as a sender, how do I send a custom message like location co-ordinates?*

CometChat allows you to send custom messages which are neither text nor media messages.

In order to send a custom message, you need to use the `sendCustomMessage()` method.

The `sendCustomMessage()` methods takes an object of the `CustomMessage` which can be obtained using the below constructor.

<Tabs>
  <Tab title="Java">
    ```java theme={null}
    CustomMessage customMessage = new CustomMessage(receiverId, receiverType,customType, customData)
    ```
  </Tab>

  <Tab title="Kotlin">
    ```kotlin theme={null}
    val customMessage = CustomMessage(receiverId, receiverType, customType, customData)
    ```
  </Tab>
</Tabs>

The above constructor, helps you create a custom message with the message type set to whatever is passed to the constructor and the category set to `custom`.

The parameters involved are:

1. `receiverId` - Unique id of the user or group to which the message is to be sent.
2. `receiverType` - Type of the receiver i.e user or group
3. `customType` - custom message type that you need to set
4. `customData` - The data to be passed as the message in the form of a JSONObject.

You can also use the subType field of the `CustomMessage` class to set a specific type for the custom message. This can be achieved using the `setSubtype()` method.

### Add Tags

To add a tag to a message you can use the `setTags()` method of the CustomMessage Class. The `setTags()` method accepts a list of tags.

<Tabs>
  <Tab title="Java">
    ```java theme={null}
    List<String> tags = new ArrayList<>();
    tags.add("pinned");
    customMessage.setTags(tags);
    ```
  </Tab>

  <Tab title="Kotlin">
    ```kotlin theme={null}
    val tags: MutableList<String> = ArrayList()
    tags.add("pinned")
    customMessage.setTags(tags)
    ```
  </Tab>
</Tabs>

Once the object of `CustomMessage` class is ready you can send the custom message using the `sendCustomMessage()` method.

<Tabs>
  <Tab title="Java (User)">
    ```java theme={null}
    private String UID = "UID";
    private String customType = "LOCATION";

    JSONObject customData = new JSONObject();
    customData.put("latitude", "19.0760");
    customData.put("longitude", "72.8777");

    CustomMessage customMessage = new CustomMessage(UID, CometChatConstants.RECEIVER_TYPE_USER, customType, customData);

    CometChat.sendCustomMessage(customMessage, new CometChat.CallbackListener<CustomMessage>() {
      @Override
      public void onSuccess(CustomMessage customMessage) {
          Log.d(TAG, customMessage.toString());
      }

      @Override
      public void onError(CometChatException e) {
          Log.d(TAG, e.getMessage());
      }
    });
    ```
  </Tab>

  <Tab title="Kotlin (User)">
    ```kotlin theme={null}
    private val UID = "UID"
    private val customType = "LOCATION"

    val customData = JSONObject()
    customData.put("latitude", "19.0760")
    customData.put("longitude", "72.8777")
    val customMessage = CustomMessage(UID, CometChatConstants.RECEIVER_TYPE_USER, customType, customData)

    CometChat.sendCustomMessage(customMessage, object : CallbackListener<CustomMessage>() {
      override fun onSuccess(customMessage: CustomMessage) {
          Log.d(TAG, customMessage.toString())
      }

      override fun onError(e: CometChatException) {
          Log.d(TAG, e.message!!)
      }
    })
    ```
  </Tab>

  <Tab title="Java (Group)">
    ```java theme={null}

    JSONObject customData = new JSONObject();
    customData.put("latitude", "19.0760");
    customData.put("longitude", "72.8777");

    CustomMessage customMessage = new CustomMessage(GUID, CometChatConstants.RECEIVER_TYPE_GROUP, customType, customData);

    CometChat.sendCustomMessage(customMessage, new CometChat.CallbackListener<CustomMessage>() {
      @Override
      public void onSuccess(CustomMessage customMessage) {
          Log.d(TAG, customMessage.toString());
      }

      @Override
      public void onError(CometChatException e) {
          Log.d(TAG, e.getMessage());
      }
    });
    ```
  </Tab>

  <Tab title="Kotlin (Group)">
    ```kotlin theme={null}
    private val GUID = "GUID"
    private val customType = "LOCATION"

    val customData = JSONObject()
    customData.put("latitude", "19.0760")
    customData.put("longitude", "72.8777")
    val customMessage = CustomMessage(GUID, CometChatConstants.RECEIVER_TYPE_GROUP, customType, customData)

    CometChat.sendCustomMessage(customMessage, object : CallbackListener<CustomMessage>() {
      override fun onSuccess(customMessage: CustomMessage) {
          Log.d(TAG, customMessage.toString())
      }

      override fun onError(e: CometChatException) {
          Log.d(TAG, e.message!!)
      }
    })
    ```
  </Tab>
</Tabs>

The above sample explains how custom messages can be used to share the location with a user. Similarly, you can send custom messages to groups.

On success, you will receive an object of `CustomMessage` class.

### Update Conversation

*How can I decide whether the custom message should update the last message of a conversation?*

By default, a custom message will update the last message of a conversation. If you wish to not update the last message of the conversation when a custom message is sent, please use `shouldUpdateConversation(boolean value)` method of the Custom Message.

    customData.put("longitude", "72.8777");

    CustomMessage customMessage = new CustomMessage(UID, CometChatConstants.RECEIVER_TYPE_USER, customType, customData);
    customMessage.shouldUpdateConversation(false);

    CometChat.sendCustomMessage(customMessage, new CometChat.CallbackListener<CustomMessage>() {
      @Override
      public void onSuccess(CustomMessage customMessage) {
          Log.d(TAG, customMessage.toString());
