edge-to-edge

Prerequisites

• Project MUST use Android Jetpack Compose.
• Project MUST target SDK 35 or later. If the SDK is lower than 35, increase the SDK to 35.

Step 1: plan

1. Locate and analyze all Activity classes to detect which have existing edge-to-edge support. For every Activity without edge-to-edge, plan to make each Activity edge-to-edge.
2. In each Activity, Locate and analyze all lists and FAB components to detect which have existing edge-to-edge support. For every component without edge-to-edge support, plan to make each of these components edge-to-edge.
3. In each Activity, scan for TextField, OutlinedTextField, or BasicTextField. If found, then you MUST verify the IME doesn't hide the input field by following the IME section of this skill.

Step 2: add edge-to-edge support

1. Add enableEdgeToEdge before setContent in onCreate in each Activity that does not already call enableEdgeToEdge.
2. Add android:windowSoftInputMode="adjustResize" in the AndroidManifest.xml for all Activities that use a soft keyboard.

Step 3: apply insets

• The app MUST apply system insets, or align content to rulers, so critical UI remains tappable. Choose only one method to avoid double padding:

  1. PREFERRED: When available, use Scaffolds and pass PaddingValues to the content lambda.

  Scaffold { innerPadding ->
      // innerPadding accounts for system bars and any Scaffold components
      LazyColumn(
          modifier = Modifier
              .fillMaxSize()
              .consumeWindowInsets(innerPadding),
          contentPadding = innerPadding
      ) { /* Content */ }
  }
  

  1. PREFERRED: When available, use the automatic inset handling or padding modifiers in material components.

     • Material 3 Components manages safe areas for its own components, including:
       • TopAppBar
       • SmallTopAppBar
       • CenterAlignedTopAppBar
       • MediumTopAppBar
       • LargeTopAppBar
       • BottomAppBar
       • ModalDrawerSheet
       • DismissibleDrawerSheet
       • PermanentDrawerSheet
       • ModalBottomSheet
       • NavigationBar
       • NavigationRail
     • For Material 2 Components, use the windowInsetsparameter to apply insets manually for BottomAppBar, TopAppBar and BottomNavigation. DO NOT apply padding to the parent container; instead, pass insets directly to the App Bar component. Applying padding to the parent container prevents the App Bar background from drawing into the system bar area. For example, for TopAppBar, choose only one of the following options:
       1. PREFERRED: TopAppBar(windowInsets = AppBarDefaults.topAppBarWindowInsets)
       2. TopAppBar(windowInsets = WindowInsets.systemBars.exclude(WindowInsets.navigationBars))
       3. TopAppBar(windowInsets = WindowInsets.systemBars.add(WindowInsets.captionBar))

  2. For components outside a Scaffold, use padding modifiers, such as Modifier.safeDrawingPadding() or Modifier.windowInsetsPadding(WindowInsets.safeDrawing).
