DataShare Error Codes

NOTE

This topic describes only module-specific error codes. For details about universal error codes, see Universal Error Codes.

Error Message

The DataShareHelper is not initialized successfully.

Description

The DataShareHelper class fails to be created.

Possible Causes

The uri specified in createDataHelper is incorrect.
The context specified in createDataHelper is incorrect. DataShare supports only the stage model.
The client application does not have the permission to start DataShareExtension from the background when the client attempts to start DataShareExtension from the background to create DataShareHelper.

Solution

Obtain the correct URI.
Check that the context of the stage model is used.
Check whether the client has the read or write permission on data. Perform the following steps:

(1) Obtain the data provider bundle name in the path of the URI. For example, the bundle name in uri = “datashareproxy://com.acts.ohos.data.datasharetest/test” is com.acts.ohos.data.datasharetest.

(2) Obtain the configuration based on the bundle name. For example, run bm dump –bundle-name com.acts.ohos.data.datasharetest to obtain the DataShareExtension configuration, and check whether the data consumer has readPermission or writePermission.
