To publish an Android app on the Google Play Store, one must create a Google Developer Account by signing up on the Google Play Console, providing personal details, and paying a one-time fee. Approval may take up to 48 hours. A Google Merchant Account is needed for financial transactions if selling or offering in-app purchases. The app setup involves filling out essential information, uploading the APK or App Bundle, and configuring the store listing. The app title should be concise and include high-traffic keywords, while descriptions should incorporate relevant keywords to enhance discoverability. The APK or App Bundle must not exceed 100MB and should be digitally signed. Store listings should include high-quality screenshots, a marketing image, and a promo video link. Pricing and distribution settings can be configured, and a content rating questionnaire must be completed accurately. The app review process typically takes up to 7 days but can be completed in as little as 2 days. Post-publication, regular updates and marketing strategies, including App Store Optimization (ASO) and social media engagement, are essential for maintaining visibility and attracting users.
