Support edge-to-edge display in authentication WebView

[andrii-bodnar]

The authentication WebView does not properly handle edge-to-edge display requirements, causing the Crowdin logo and other UI elements to be obscured by the system status bar on Android 15+ devices.

Current Behavior

When opening the authentication flow:

• The WebView content extends behind the system status bar
• The Crowdin logo is covered by the status bar (time, notification icons, etc.)
• Important UI elements in the authentication page are not fully visible
• When dragging down the status bar, the logo becomes visible, confirming the content is behind system UI

Expected Behavior

The authentication WebView should:

• Respect window insets and system bars
• Apply proper padding to keep content in the safe drawing area
• Ensure all UI elements (logo, buttons, text) remain visible and not obscured by system bars, navigation bars, or display cutouts

Technical Details

Root Cause:

• Starting with Android 15 (API 35), edge-to-edge display is enforced by default
• The AuthActivity and its layout do not implement window insets handling
• The WebView doesn't apply padding for system bars

Affected Component:

• AuthActivity (crowdin/src/main/java/com/crowdin/platform/auth/AuthActivity.kt)
• auth_layout.xml (crowdin/src/main/res/layout/auth_layout.xml)

Proposed Solution

Implement window insets handling in AuthActivity:

1. Enable edge-to-edge in the activity:

WindowCompat.setDecorFitsSystemWindows(window, false)

2. Apply window insets to the WebView or root layout:

ViewCompat.setOnApplyWindowInsetsListener(webView) { view, windowInsets ->
    val insets = windowInsets.getInsets(WindowInsetsCompat.Type.systemBars())
    view.updatePadding(
        top = insets.top,
        bottom = insets.bottom,
        left = insets.left,
        right = insets.right
    )
    WindowInsetsCompat.CONSUMED
}

Environment
