    This document describes how to customize the UI of TUICallKit and provides two schemes for customization: slight UI adjustment and custom UI implementation.

    Scheme 1. Slight UI Adjustment

    You can adjust the UI of TUICallKit by directly modifying the UI source code in the Android/tuicallkit-kt folder in tencentyun/TUICallKit.

    Replacing icons

    You can directly replace the icons in the tuicallkit-kt/src/main/res/drawable-xxhdpi folder to customize the color tone and style of all the icons in your application. When you replace an icon, make sure the filename is the same as the original icon.

    Replacing ringtones

    You can replace ringtones by replacing the three audio files in the tuicallkit-kt/src/main/res/raw folder.
    The sound of making a call
    The sound of being hung up
    The ringtone for incoming calls

    Replacing text

    You can modify the strings on the video call UI by modifying the strings.xml file in tuicallkit-kt/src/main/res/values-**/.

    Scheme 2. Custom UI Implementation

    The entire call feature of TUICallKit is implemented based on the UI-less component TUICallEngine. You can delete the tuicallkit folder and implement your own UIs based entirely on TUICallEngine.


    TUICallEngine is the underlying API of the entire TUICallKit component. It provides key APIs such as APIs for making, answering, declining, and hanging up one-to-one audio/video and group calls and device operations.
    Creates a TUICallEngine instance (singleton).
    Terminates a TUICallEngine instance (singleton).
    Completes the authentication of basic audio/video call capabilities.
    Registers an event listener.
    Unregisters an event listener.
    Makes a one-to-one call.
    Makes a group call.
    Answers a call.
    Declines a call.
    Hangs up a call.
    Ignores a call.
    Invites a user during a group call.
    Joins the current group call actively.
    Switches the call media type, such as from video call to audio call.
    Subscribes to the video stream of a remote user.

    Disables the camera.
    Switches between the front and rear cameras.

    Set the rendering mode of video image.
    Set the encoding parameters of video encoder.
    Advanced features.

    TUICallObserver is the callback even class of TUICallEngine. You can use it to listen on the desired callback events.
    An error occurred during the call.
    A call was received.
    The call was canceled.
    The call was connected.
    The call ended.
    The call media type changed.
    A user declined the call.
    A user didn't respond.
    A user was busy.
    A user joined the call.
    A user left the call.
    Whether a user had a video stream.
    Whether a user had an audio stream.
