Is Your Android App Broken on API 35? 📱💥 The Edge-to-Edge Survival Guide

 A 3-step survival guide to mastering mandatory Edge-to-Edge layouts in Android 15

Edge-to-Edge Survival Guide

If you’ve recently bumped your targetSdkVersion to 35 (Android 15), you might have noticed something jarring: your beautiful layout is suddenly shoved behind the status bar, or your bottom navigation is drowning in the navigation bar.

Android 15 doesn’t break your UI — it exposes assumptions your layout has been making for years.

The Big Shift: Edge-to-Edge is No Longer Optional

In previous versions of Android, developers had a choice. You could stay within the “safe zones” or manually request to go “edge-to-edge.” Starting with Android 15, Google has flipped the switch. For apps targeting API 35, Edge-to-Edge is mandatory.

Why the change?

Google is pushing for a cohesive, premium look. By removing the solid bars at the top and bottom, apps feel like an integrated part of the device hardware. Think of it as painting the entire canvas, then placing your UI safely inside the frame using insets.

What has actually changed?

  • System UI Flags No Longer Control Layout: Legacy View.SYSTEM_UI_FLAG_* constants no longer influence layout behavior on API 35+.
  • Default Transparency: The system forces the status and navigation bars to be transparent. While APIs like setStatusBarColor still exist, they no longer prevent content from drawing behind the bars.
  • Enforced Overlap: Your app draws behind system bars by default. If you don’t handle insets, your interactive elements will be unclickable and your text unreadable.

How to Fix Your UI in 3 Steps

If your content is overlapping with the clock or the gesture pill, follow this roadmap.

1. Enable it Explicitly (Backward Compatibility)

Even though API 35 forces this, call enableEdgeToEdge() in your Activity’s onCreate. This ensures your app looks modern on Android 10 through 14 as well.

override fun onCreate(savedInstanceState: Bundle?) {
    // 1. Must be called BEFORE setContentView
    enableEdgeToEdge() 
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)
}

2. The Solution: Handle WindowInsets

Instead of hardcoding padding (an official anti-pattern!), we use a listener. This asks the system for the exact dimensions of the bars — accounting for notches and navigation styles.

// Apply this to your root view or specific containers
ViewCompat.setOnApplyWindowInsetsListener(findViewById(R.id.main_root)) { v, insets ->
    // Fetch system bars (status/nav) and physical cutouts (notches)
    val bars = insets.getInsets(
        WindowInsetsCompat.Type.systemBars() or 
        WindowInsetsCompat.Type.displayCutout()
    )

    // Update padding dynamically
    v.updatePadding(
        left = bars.left,
        top = bars.top,
        right = bars.right,
        bottom = bars.bottom
    )

    // Return the insets. 
    // Use .CONSUMED only if children should NOT receive these insets.
    insets
}

🛑 Common Mistakes to Avoid

  • Double-Padding: Applying insets to both a parent container and its children, resulting in massive, awkward gaps. (Compose users: apply insets at the Scaffold or top-level composable to avoid this).
  • Forgetting Dialogs: Not handling insets for Bottom Sheets or Dialogs, which often live in their own windows and won’t inherit root padding.
  • Hardcoded Values: Guessing that a status bar is “24dp.” Devices vary wildly; always trust the WindowInsets object.

✅ API 35 Edge-to-Edge Migration Checklist

  • [ ] Call enableEdgeToEdge() before setContentView.
  • [ ] Replace all systemUiVisibility logic with WindowInsets.
  • [ ] Apply WindowInsets listeners to root containers or Scaffolds.
  • [ ] Explicitly verify Dialogs and Bottom Sheets on a real device.
  • [ ] Test on both Gesture Navigation and 3-Button Navigation.
  • [ ] Test on a device with a Display Cutout (notch/hole-punch).

🙋‍♂️ Frequently Asked Questions (FAQs)

Can I opt-out of Edge-to-Edge on Android 15?

Technically, no. If you target API 35, the system forces this behavior. You must manage the layout yourself.

Does this affect Jetpack Compose?

Yes, but it’s much simpler! Use Modifier.safeDrawingPadding() or Modifier.windowInsetsPadding(WindowInsets.systemBars) on your top-level Composables.

Why is my background color appearing behind the status bar now?

That’s the intended behavior! Your background should bleed into the status area, while your content (text, buttons) stays safe via insets.

  • Have you bumped your targetSdkVersion to 35 yet? What was the first thing that "broke"?
  • Are you finding WindowInsets easier to manage in XML or Jetpack Compose?
  • Do you think this mandatory change is better for the ecosystem?

Coroutines & Flows: 5 Critical Anti-Patterns That Are Secretly Slowing Down Your Android App

Image
 Stop sneaky performance killers. Spot and fix Kotlin issues that cause crashes, memory leaks, and laggy UIs. Coroutines and Kotlin Flows are the bedrock of modern asynchronous programming on Android. They allow us to write clean, sequential-looking code that manages complex background operations, network calls, and database transactions. But power comes with responsibility. Many developers, despite using Coroutines daily, unknowingly introduce subtle mistakes —  anti-patterns  — that lead to memory leaks, silent crashes, data loss, and UI jank. Based on insights from top-tier Android development, here are five critical Coroutine and Flow anti-patterns you must identify and fix today, plus one bonus pitfall I often see in code reviews. 1. The Main Thread Trap: Heavy Work in  viewModelScope When you launch a coroutine inside a  ViewModel  using  viewModelScope.launch { ... } , where do you think that work runs by default? The  Main Thread ! If your...

Stop Writing Massive when Statements: Master the State Pattern in Kotlin

Image
 Tame Your Codebase with Elegant, Scalable, and Type-Safe State Machines Do you manage complex objects that change their behavior dramatically based on their internal status? If so, you’ve likely battled a common foe: the sprawling  when  statement that haunts every method in your class. It looks something like this: fun handleAction () { when (state) { State.A -> { /* logic for A */ } State.B -> { /* logic for B */ } State.C -> { /* logic for C */ } // ... and the list keeps growing! } } Every time you add a new state (e.g.,  State.D ), you have to hunt down and update  every single function  with a new case. This is a maintenance nightmare, a direct violation of the  Open/Closed Principle  (OCP), and a major code smell. Your logic is scattered by  action  when it should be grouped by  state . The solution? The  State Pattern . And with modern Kotlin, we can implement it w...
