/**
|
|
* This class handles 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* package has been replaced by a newer version of the same package.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 handles
|
|
* {@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 to this class to 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 forwarded to this class 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 forwarded to this class
|
|
* to check 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 forwarded to
|
|
* this class to check whether the setup wizard's icon should be appeared or not on the launcher
|
|
* depending on which partition this IME is installed.
