[Bug][Android 15] Edge-to-edge layout overlapping in PreferencesActivity (targetSdk 35)

Describe the Bug

On Android 15 (API 35), system-enforced Edge-to-Edge (ENFORCE_EDGE_TO_EDGE) causes layout overlapping in PreferencesActivity when targeting SDK 35 (targetSdkVersion 35):

1. Top overlap: The system status bar (clock, battery, icons) is rendered directly on top of the Toolbar (<- Settings and back button).
2. Bottom overlap: The 3-button system navigation bar (Back, Home, Recents) overlaps the bottom preference items (e.g., "Root Explorer" switch and its description) without proper window insets.

Device & Environment Information

• App Version: Amaze File Manager 3.11.3 (versionCode 125, targetSdkVersion 35)
• Device Model: Xiaomi POCO X6 5G / Redmi Note 13 Pro 5G (garnet / 23122PCD1G)
• Android Version: Android 15 (VanillaIceCream, API level 35)
• ROM / OS Build: LineageOS 22 (lineage_garnet-userdebug 15 BP1A.250505.005)

Root Cause Analysis

In Android 15, edge-to-edge is mandatory for applications targeting API 35.
In res/layout/activity_preferences.xml, the root RelativeLayout does not have android:fitsSystemWindows="true", nor does PreferencesActivity apply WindowInsetsCompat to handle system bars padding.

Suggested Fix

Add android:fitsSystemWindows="true" to the root layout in activity_preferences.xml:

--- a/app/src/main/res/layout/activity_preferences.xml
+++ b/app/src/main/res/layout/activity_preferences.xml
@@ -2,3 +2,4 @@
 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:id="@id/activity_preferences"
+    android:fitsSystemWindows="true"
     android:layout_width="match_parent"
     android:layout_height="match_parent">

Screenshots

• Before (Overlapped UI with targetSdk 35 & missing insets):
  

• After (Fixed with fitsSystemWindows / targetSdk 34 insets applied):
  

Start with app/src/main/res/layout/activity_preferences.xml and inspect the root RelativeLayout, then review PreferencesActivity for existing inset handling. Apply the requested system-bar inset fix and verify on Android 15 with targetSdkVersion 35 that the toolbar and bottom preference items no longer overlap the system bars.
