Android 16 Compatibility Guide

Handling Screen Orientation and Resizable Activity Settings

Starting from Android 16 (API level 36), Android will ignore certain restrictions like fixed orientation and non-resizable windows on large-screen devices (foldables, tablets, etc.). To ensure your app works properly, you must update your Unity Player Settings.

---

✅ Step 1: Allow Flexible Screen Orientation

Default Orientation

1. Go to Edit > Project Settings > Player

2. Select the Android tab

3. Open Resolution and Presentation

4. Set Default Orientation to:

✔ Auto Rotation

This prevents the system from locking the orientation to portrait or landscape, which may be ignored or cause layout issues on foldables.

---

✅ Step 2: Enable Resizable Activity

Resizable Window

1. Go to Player > Android > Other Settings

2. Scroll down to Configuration

3. Make sure Resizable Window is:

✔ Enabled (checked)

This ensures that your app can run in split-screen and multi-window modes, which is required on Android 16+ large screens.

⚠️ Why This Matters

If you leave the following settings:

<activity android:screenOrientation="portrait" android:resizeableActivity="false" />

Android 16 will ignore them on tablets and foldables, potentially breaking your layout. Unity may add these automatically unless you adjust your Player Settings as described.

---

🔍 Optional: Custom Manifest (Advanced)

If you're overriding the manifest manually:

• Avoid hardcoding android:screenOrientation

• Set resizeableActivity="true"

• But remember: Unity Player Settings may overwrite your manifest unless you're using a custom mainTemplate.gradle and manifest override.

✅ Summary

Setting	Location	Recommended
Default Orientation	Player > Android > Resolution and Presentation	Auto Rotation
Resizable Window	Player > Android > Other Settings	Enabled ✔

By following these steps, you ensure your Unity app is ready for Android 16, and works properly across all screen sizes and form factors.
