Frequently Asked Question
Just like the ID card number of each person, an app package name uniquely identifies an app. The standard format is com.xxx.xxx, containing three fields whose values are in lowercase letters. It is recommended that each segment be controlled within 3-20 letters. Other characters and spaces are not allowed. If your package name is duplicate with an existing one, the system displays a message, indicating that the package name already exists. In this case, you need to change the package name.
