Fastboard Android

Fastboard is a quick access to the agora-whiteboard wrapper library
For historical reasons, agora-whiteboard carries a lot of legacy baggage. It's contains a large number of apis, and some concepts are cost time to understand.
Fastboard is aimed to reduce the number of apis and the cost of access. It is pinned on the following features

• Low-cost
• Scenario-based
• Configurable

Environment

Requirements

• Android SDK Version >= 21
• Android Tools Build >= 4.1.0

build.gradle Configuration

// project build
allprojects {
    repositories {
        // ...
        maven { url 'https://jitpack.io' }
    }
}

// app build
android {

        targetCompatibility JavaVersion.VERSION_1_8
    }
}

dependencies {
    implementation "com.github.netless-io:fastboard-android:1.7.0"
}

Quick start

the Fastboard contains default UI and default exceptions, event handler. Ideally, new users will be able to access the whiteboard with limited configuration.

example can be found in GetStartActivity

Layout

<OuterLayout>
    <!-- ... -->
    <io.agora.board.fast.FastboardView
        android:id="@+id/fastboard_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
</OuterLayout>

Join Room

Java

private void setupFastboard() {
    FastboardView fastboardView = findViewById(R.id.fastboard_view);
    Fastboard fastboard = fastboardView.getFastboard();

    FastRoomOptions roomOptions = new FastRoomOptions(
        USER_APP_ID,
        roomUUID,
        roomToken,
        uid,
        FastRegion.CN_HZ
    );
    
    FastRoom fastRoom = fastboard.createFastRoom(roomOptions);
    fastRoom.join();
}

Kotlin

private fun setupFastboard() {
    val fastboardView = findViewById<FastboardView>(R.id.fastboard_view)
    val fastboard = fastboardView.fastboard
    val roomOptions = FastRoomOptions(
        USER_APP_ID,
        roomUUID,
        roomToken,
        uid,
        FastRegion.CN_HZ
    )

    val fastRoom = fastboard.createFastRoom(roomOptions)
    fastRoom.join()
}

Configuration

Dark Mode

Java

private void updateDarkMode(boolean darkMode) {
    FastStyle fastStyle = fastRoom.getFastStyle();
    fastStyle.setDarkMode(darkMode);
    fastRoom.setFastStyle(fastStyle);
}

Kotlin

private fun updateDarkMode(darkMode: Boolean) {
    val fastStyle: FastStyle = fastRoom.fastStyle.apply {
        isDarkMode = darkMode
    }
    fastRoom.fastStyle = fastStyle
}

Custom Main Color

Java

private void updateMainColor(@ColorInt int color) {
    FastStyle fastStyle = fastRoom.getFastStyle();
    fastStyle.setMainColor(color);
    fastRoom.setFastStyle(fastStyle);
}

Kotlin

private fun updateMainColor(@ColorInt color: Int) {
    val fastRoom = FastRoom();
    val fastStyle: FastStyle = fastRoom.fastStyle.apply {
        mainColor = color
    }
    fastRoom.fastStyle = fastStyle
}

Custom ToolBox

Java
