| * 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| * package has been replaced by a newer version of the same package.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. |
