 This project uses GDExtension to wrap the Epic Online Services C SDK so that it can be easily used in Godot using GDScript, C#, etc with similar class hierarchy and static type support. It makes use of signals for sending events like user login, logout, achievement unlock, etc.

+## Exporting for Android
+
+### Pre-requisites
+
+- EOS Android SDK (Download from [Epic Developer Portal](https://dev.epicgames.com/portal))
+
+1. Setup the Android Build Template in your Godot project by following the tutorial [Gradle builds for Andriod](https://docs.godotengine.org/en/stable/tutorials/export/android_gradle_build.html). This will create an android project in `res://android/build`.
+
+2. Now with reference to the tutorial [Add the EOS SDK to Your Android Studio Project](https://dev.epicgames.com/docs/epic-online-services/platforms/android#4-add-the-eos-sdk-to-your-android-studio-project), perform the following steps.
+
+3. In the `res://android/build/build.gradle` file, add the following lines after the implementations in the `dependencies` section.
+
+	Before
+	```
+	dependencies {
+    	implementation libraries.kotlinStdLib
+    	implementation libraries.androidxFragment
+		... other code
+	```
+
+	After
+	```
+	dependencies {
+		implementation libraries.kotlinStdLib
+		implementation libraries.androidxFragment
+		
+		// EOS SDK dependencies
+		implementation 'androidx.appcompat:appcompat:1.0.0'
+		implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
+		implementation 'androidx.security:security-crypto:1.0.0'
+		implementation 'androidx.browser:browser:1.0.0'
+		implementation files('../../../thirdparty/eos-sdk/SDK/Bin/Android/static-stdc++/aar/eos-sdk.aar')
+
+		...other code
+	```
+
+4. In the `res://android/build/build.gradle` file, add the following lines after the `defaultConfig` in the `android` section.
+	
+	Before
+	```
+	android {
+
+		... other code
+
+		defaultConfig {
+			... other code
+		
+			// Feel free to modify the application id to your own.
+			applicationId getExportPackageName()
+			versionCode getExportVersionCode()
+			versionName getExportVersionName()
+			minSdkVersion getExportMinSdkVersion()
+			targetSdkVersion getExportTargetSdkVersion()
+
+			missingDimensionStrategy 'products', 'template'
+		}
+
+		... other code
+	```
+
+	After
+	```
+	android {
+
+		... other code
+
+		defaultConfig {
+			... other code
+		
+			// Feel free to modify the application id to your own.
+			applicationId getExportPackageName()
+			versionCode getExportVersionCode()
+			versionName getExportVersionName()
+			minSdkVersion getExportMinSdkVersion()
+			targetSdkVersion getExportTargetSdkVersion()
+
+			missingDimensionStrategy 'products', 'template'
+
+			// This is needed by EOS Android SDK
+			String ClientId = "PUT YOUR EOS CLIENT ID HERE"
+			resValue("string", "eos_login_protocol_scheme", "eos." + ClientId.toLowerCase())
+		}
+
+		... other code
+	```
+
+5. In the `res://android/build/config.gradle` file, update the `minSdk` to `23` to match with the requirements of the `EOS Android SDK`.
+
+	Before
+	```
+	minSdk             : 22,
+	```
+	After
+	```
+	minSdk             : 23,
+	```
+
+6. In the `res://android/build/src/com/godot/game/GodotGame.java` file, update it as follows.
+	```java
+	package com.godot.game;
+
+	import com.epicgames.mobile.eossdk.EOSSDK;     // added
+	import org.godotengine.godot.GodotActivity;
+
+	import android.os.Bundle;
+
+	public class GodotApp extends GodotActivity {
+		static {                                   // added
+			System.loadLibrary("EOSSDK");          // added
+		}                                          // added
+		
+		@Override
+		public void onCreate(Bundle savedInstanceState) {
+			EOSSDK.init(getApplicationContext());  // added
+
+			setTheme(R.style.GodotAppMainTheme);
+			super.onCreate(savedInstanceState);
+		}
+	}
+
+	```
+
+7. Now open your project in the Godot Editor, and goto `Project -> Export` and create a new Android export profile.
+
+8. In the `Gradle Build` section, enable `Use Gradle Build`. In the `Architectures` section enable `arm64-v8a`. In the `Permissions` section ensure that `ACESSS_NETWORK_STATE`, `ACCESS_WIFI_STATE` and `INTERNET` are enabled. These permissions are needed for the EOS SDK to work. Fill in the other details such as package name, etc as needed.
+
+9. You can now export the Android APK by clicking the Export Project button.
