+## Android Setup
+
+### Keystore setup
+```bash
+keytool -genkey -v -keystore release.keystore -keyalg RSA -keysize 2048 -validity 10000 -alias release
+```
+- This is required to store local credentials securely (not used for now).
+- But necesseary in order to restrict the particular api key to a particular app (through the sha1 of the associated keystore).
+
+
+### Building and secret credentials
+Following the guide under [https://developers.google.com/maps/flutter-package/config#android_1](https://developers.google.com/maps/flutter-package/config#android_1).
+- Add the following to `android/build.gradle`:
+    ```gradle
+    buildscript {
+        dependencies {
+            classpath "com.google.android.libraries.mapsplatform.secrets-gradle-plugin:secrets-gradle-plugin:2.0.1"
+        }
+    }
+    ```
+- Add the following to `android/app/build.gradle`:
+    ```gradle
+    plugins {
+        // ...
+        id 'com.google.android.libraries.mapsplatform.secrets-gradle-plugin'
+    }
+    ```
+- Add the credentials to `android/secrets.properties`:
+    ```properties
+    MAPS_API_KEY=YOUR_API_KEY
+    ```
+- Reference the credentials in `android/app/src/main/AndroidManifest.xml`:
+    ```xml
+    <meta-data
+        android:name="com.google.android.geo.API_KEY"
+        android:value="${MAPS_API_KEY}" />
+    ```
+
+
+### Using the credentials in CI
+- Add the base64 encoded credentials to the repository secrets (e.g. `ANDROID_SECRETS`).
+    ```bash
+    base64 -i android/secrets.properties
+    ```
+- Use the following in the CI script:
+    ```bash
+    echo {{ secrets.ANDROID_SECRETS }} | base64 -d > android/secrets.properties
+    ```
