Wi-Fi Subsystem ChangeLog
cl.location.1 Location Service Permission Change
From API version 9, the ohos.permission.APPROXIMATELY_LOCATION permission is added for obtaining the approximate location.
If you use API version 9 or later, you need to apply for both the ohos.permission.LOCATION and ohos.permission.APPROXIMATELY_LOCATION permissions. Applying for only the ohos.permission.LOCATION permission will fail.
Change Impacts
Applications using API versions earlier than 9 are not affected. For an application using API version 9 or later, the method for applying for the location permission is changed. The details are as follows:
Before using basic location capabilities, check whether your application has been granted the permission to access the device location information. If not, your application needs to obtain the permission from the user as described below.
The system provides the following location permissions:
ohos.permission.LOCATION
ohos.permission.APPROXIMATELY_LOCATION
ohos.permission.LOCATION_IN_BACKGROUND
If your application needs to access the device location information, it must first apply for required permissions. Specifically speaking:
API versions earlier than 9: Apply for ohos.permission.LOCATION.
API version 9 and later: Apply for ohos.permission.APPROXIMATELY_LOCATION, or apply for ohos.permission.APPROXIMATELY_LOCATION and ohos.permission.LOCATION. Note that ohos.permission.LOCATION cannot be applied for separately.
API Version | Location Permission | Permission Application Result | Location Accuracy |
---|---|---|---|
Earlier than 9 | ohos.permission.LOCATION | Success | Location accurate to meters |
9 and later | ohos.permission.LOCATION | Failure | No location obtained |
9 and later | ohos.permission.APPROXIMATELY_LOCATION | Success | Location accurate to 5 kilometers |
9 and later | ohos.permission.APPROXIMATELY_LOCATION and ohos.permission.LOCATION | Success | Location accurate to meters |
If your application needs to access the device location information when running in the background, it must be configured to be able to run in the background and be granted the ohos.permission.LOCATION_IN_BACKGROUND permission. In this way, the system continues to report device location information after your application moves to the background.
You can declare the required permissions in your application’s configuration file. For details, see the permission application guide.
