Common Mistakes

Using 'initialize' instead of 'getInstance' causes a compile error.

Trying to call 'create' or 'start' methods which do not exist.

Common Mistakes

Using an invalid method name that is not a string.

Forgetting to put the parameter inside the bundle.

💡 Hint

Common Mistakes

Using 'setUserID' with uppercase 'ID' causes a method not found error.

Using 'setUser' or 'userId' which are not valid methods.

The correct method to set the user ID is setUserId with a lowercase 'd'.

Common Mistakes

Using 'CONTENT_TYPE' instead of 'ITEM_ID' for the parameter key.
