* This class detects the {@link Intent#ACTION_MY_PACKAGE_REPLACED} broadcast intent when this IME
* package has been replaced by a newer version of the same package. This class also detects
* {@link Intent#ACTION_BOOT_COMPLETED} and {@link Intent#ACTION_USER_INITIALIZE} broadcast intent.
*
* If this IME has already been installed in the system image and a new version of this IME has
* been installed, {@link Intent#ACTION_MY_PACKAGE_REPLACED} is received by this receiver and it
* will hide the setup wizard's icon.
*
* If this IME has already been installed in the data partition and a new version of this IME has
* been installed, {@link Intent#ACTION_MY_PACKAGE_REPLACED} is received by this receiver but it
* will not hide the setup wizard's icon, and the icon will appear on the launcher.
*
* If this IME hasn't been installed yet and has been newly installed, no
* {@link Intent#ACTION_MY_PACKAGE_REPLACED} will be sent and the setup wizard's icon will appear
* on the launcher.
*
* When the device has been booted, {@link Intent#ACTION_BOOT_COMPLETED} is received by this
* receiver and it checks whether the setup wizard's icon should be appeared or not on the launcher
* depending on which partition this IME is installed.
*
* When a multiuser account has been created, {@link Intent#ACTION_USER_INITIALIZE} is received
* by this receiver and it checks the whether the setup wizard's icon should be appeared or not on
* the launcher depending on which partition this IME is installed.
