+# Google OAuth Setup for Android APK
+
+## Step 1: Create a Google Cloud Project
+1. Go to https://console.cloud.google.com/
+2. Click **Select a project** → **New Project**
+3. Name it and click **Create**
+
+## Step 2: Enable the Photos Library API
+1. Go to **APIs & Services** → **Library**
+2. Search for **Photos Library API** → Enable it
+
+## Step 3: Configure the OAuth Consent Screen
+1. Go to **APIs & Services** → **OAuth consent screen**
+2. Choose **External** → **Create**
+3. Fill in:
+   - **App name**: MASS Photo App
+   - **User support email**: your email
+   - **Developer contact**: your email
+4. **Scopes** → Add or Remove Scopes:
+   - `openid`
+   - `https://www.googleapis.com/auth/photoslibrary`
+   - `https://www.googleapis.com/auth/photoslibrary.appendonly`
+   - `https://www.googleapis.com/auth/userinfo.email`
+   - `https://www.googleapis.com/auth/userinfo.profile`
+5. **Test users** → Add your Google account email address
+
+## Step 4: Create an Android OAuth Client ID
+1. Go to **APIs & Services** → **Credentials**
+2. **+ Create Credentials** → **OAuth client ID**
+3. Application type: **Android**
+4. Package name: `com.bobthebob.massphotoapp`
+5. SHA-1 certificate fingerprint: get it by running `eas credentials --platform android`
+6. Click **Create** and copy the **Client ID**
+7. Open `src/AUTH/GoogleAUTH.js` and set `ANDROID_CLIENT_ID` to the copied value
+
+## How it works
+- The **Android client ID** is used for both the authorization request and the
+  token exchange. Google verifies the request using the app's package name +
+  SHA-1 signing certificate, so no redirect URI registration is needed.
+- The redirect goes to `com.bobthebob.massphotoapp:/oauthredirect` which
+  Android routes back into the app via the intent filter in `app.json`.
+- Android clients are public (no `client_secret` required). PKCE `code_verifier`
+  is used to secure the authorization code exchange.
+
+## Testing the API with OAuth Playground
+1. Go to https://developers.google.com/oauthplayground
+2. Click the gear icon → check "Use your own OAuth credentials"
+3. You will need a **Web application** client for the playground only (the
+   playground cannot use Android clients). Create one in the console if needed,
+   add `https://developers.google.com/oauthplayground` to its redirect URIs.
+4. Select Photos Library API scopes and authorize
+5. Copy the access token and run: `node TEST/testGooglePhotosAPI.js <TOKEN>`
