To fix the error **"unable to initialize the Unity Engine Gfx api"** when running a Unity application on an Android emulator, follow these steps:
---
### π§ 1. **Configuring the graphics of the emulator**
- **Change the emulator graphics driver**:
In AVD Manager, open the settings of your Pixel emulator β section **Emulated Performance** β **Graphics**.
Use **ANGLE (D3D11)** for Windows or **SwiftShader** (if the error occurs on Android 8.1).
- Avoid **Automatic** and **Native GPU** (often cause conflicts with Unity).
- **Create a new emulator**:
Select Android 13 (API 33) with the image **Google Play** β screen resolution 1080x1920.
Turn off the **Play Store** (sometimes causes additional load).
---
### π οΈ 2. ** Unity Configuration**
- **Build Settings**:
In **Player Settings** β **Other Settings**:
Specify **Minimum API Level 26** (Android 8.1) and **Target API Level 33**.
Disable **Auto Graphics API** β manually add **OpenGLES3**.
In **Graphics** β **Vulkan** β uncheck the box (emulators don't support it well).
- **AI Foundation Framework**:
- If you are using neural network models, check their compatibility with the x86 architecture of the emulator.
---
### π» 3. **System requirements**
- **Enable hardware acceleration**:
For Windows: activate **Hyper-V** or **Windows Hypervisor Platform**.
For AMD CPU: Enable **SVM** in the BIOS.
- **Allocate more resources**:
Emulator RAM: minimum **4096 MB**.
Storage Size: **8 GB** (for Android 13).
---
### π 4. ** Diagnostics**
- **Check the Unity logs**:
- Open **Window β Analysis β Log**.
- **Test it on a real device**:
---
#### π 5. **Emergency measures**
- **Rebuild the project**:
``bash
# Delete
the rm -rf Library cache/ Temp/ ProjectSettings/ProjectVersion.txt
``
- **Use the Genymotion emulator** (more stable for Unity):
- Create a device with Android 13 and graphics **OpenGL ES 3.0**.
