Introduction

The bundle management framework is provided by OpenHarmony for you to manage application bundles (installation packages). The following figure shows the architecture of the bundle management framework.

Figure 1 Bundle management framework architecture

• BundleKit includes external APIs provided by the Bundle Manager Service, including the APIs for application installation and uninstallation, bundle information query, and bundle state change listeners.

• The bundle scanning sub-module parses pre-installed or installed bundles on the local device and extracts information from them for the bundle management sub-module to manage and make the information persistent for storage.

• The bundle installation sub-module installs, uninstalls, and updates a bundle.

• The bundle installation service is an independent process used to create or delete installation directories and has high permissions.

• The bundle management sub-module manages information related to application bundles and stores persistent bundle information.

• The bundle security management sub-module verifies signatures, and grants and manages permissions.

• The Bundle Manager Service is running in the foundation process.
• The Bundle Manager Service is registered with sa_manager. sa_manager runs in the foundation process and sets up a thread runtime environment for the service. For details about how to create and use the Bundle Manager Service, see SA Framework.
• The Bundle Manager Service starts upon OS startup.
• You can use the bm tool to install the specified HAP. (Taking hispark_taurus as an example, you can obtain the bm tool from the out/hispark_taurus/ipcamera_hispark_taurus/dev_tools/bin directory after the version building.)

./bin/bm install -p /nfs/xxxx.hap
