Workflow for Requesting Permissions

You need to determine whether your application needs related permissions before accessing data or performing an operation. If permissions are required, request the permissions in the application installation package.

The procedure for requesting a permission varies depending on the permission level and authorization mode. Before requesting a permission, you need to:

Determine the permission type in the related permission list.
Request the permission by following the corresponding operation path.

Requesting Permissions for normal Applications

Permission Type	Authorization Mode	Operation Path
Open system_grant permission	system_grant	Declare permission > Access API
Open user_grant permission	user_grant	Declare permission > Request user authorization > Access API
system_grant permission available for system applications via ACL Restricted permission	system_grant	Request restricted permission > Declare permission > Access API
user_grant permission available for system applications via ACL Restricted permission	user_grant	Request restricted permission > Declare permission > Request user authorization > Access API

NOTE

A normal application cannot request a system_basic permission whose Enable via ACL is false.

You can use DevEco Studio to request a permission via ACL. However, this approach applies to the applications in debug phase, but not to the applications to be released to an app market. For a commercial application, apply for a release certificate and profile in the app market.

Requesting Permissions for system_basic Applications

Permission APL	Authorization Mode	Enable via ACL	Operation Path
normal or system_basic	system_grant	-	Declare permission > Access API
normal or system_basic	user_grant	-	Declare permission > Request user authorization > Access API
system_core	system_grant	true	Request restricted permission > Declare permission > Access API
system_core	user_grant	true	Request restricted permission > Declare permission > Request user authorization > Access API

To change the application APL to system_basic or system_core, modify the HarmonyAppProvision file (Toolchains / _{Version} _/ lib / UnsgnedReleasedProfileTemplate.json file in the SDK directory) of the application when developing the application installation package, and sign the application again.

Example

Modify the "bundle-info" > "apl" field in the file.

"bundle-info" : {
    // ...
    "apl": "system_basic",
    // ...
},

NOTE Modifying the HarmonyAppProvision configuration file applies to the applications in the debug phase, but not to the applications released to the app market. For a commercial application, apply for a release certificate and profile in the app market.
