Android Package Name Generator & Validator
Generate standards-compliant reverse-domain Android application IDs (` applicationId `) and validate custom package strings instantly.
Android Package Naming Rules
Reverse Domain Format
Android convention dictates starting with a reverse domain name (e.g., `com.company.app`) to ensure unique namespace identification across Google Play.
Character Constraints
Package names must consist of letters, numbers, and underscores only. Each segment must start with a letter and avoid Java reserved keywords.
Application ID vs Namespace
In modern AGP (Android Gradle Plugin), `applicationId` specifies your unique Play Store ID, while `namespace` controls your R class and source package folder paths.
