4. Create OAuth 2.0 credentials:
   • Go to "Credentials"
   • Click "Create Credentials" > "OAuth client ID"
   • Choose "Android" as application type

Local Setup

1. Clone the repository:

   git clone https://github.com/YadavYashvant/ApkExtractor.git

2. Configure Google Services:

   • Copy google-services.template.json to google-services.json
   • Replace the placeholder values with your Google Cloud project credentials

3. Update OAuth Client ID:

   • Open Config.kt
   • Replace the OAUTH_CLIENT_ID value with your OAuth client ID
   • An example Config.kt file can be written as follows -
