Firebase UI loading box

Question

When you launch FirebaseUI using intent, for a second you can see a popup showing you information that it's loading. Is there a way to change the message and style of the popup?

Answer 1

You can change the loading message by overriding that string on your strings.xml file:

<resources>
    <string name="fui_progress_dialog_signing_up">Creating your shiny new account...</string>
</resources>

And you can change the style popup by creating a theme that has FirebaseUI as it's parent:

<style name="GreenTheme" parent="FirebaseUI">
    <!-- Required for sign-in flow styling -->
    <item name="colorPrimary">@color/material_green_500</item>
    <item name="colorPrimaryDark">@color/material_green_700</item>
    <item name="colorAccent">@color/material_purple_a700</item>

    <item name="colorControlNormal">@color/material_green_500</item>
    <item name="colorControlActivated">@color/material_lime_a700</item>
    <item name="colorControlHighlight">@color/material_green_a200</item>
    <item name="android:windowBackground">@color/material_green_50</item>
</style>
