1. Problem description:
Using Huawei's built-in MapComponent, it was found that it could not be displayed. Check the log, there is an error reported at the bottom of MapRender.
Solution:
Please follow the following steps to check the map service, especially the fingerprint part of the signature certificate.
1. Generally, the map is not displayed, which may be related to the fact that the SHA256 fingerprint certificate configuration, network, positioning permissions, and not opening the map service. If the permissions have just been configured, it will take 24 hours to take effect (the mobile phone system time can be set for 24 hours later).
The clientid is written correctly under the metadata node in the .json5 file - you need to write the client_id information directly in it. You cannot reference the value in the resource file through the $ character, and you cannot parse this reference method at present;
3. The developer needs to check whether the current signature certificate fingerprint is also automatically signed. It needs to be changed to manual signature and needs to be consistent with the certificate fingerprint configured on the AGC.
Signing certificates are used in this option. Configuration method “Select SHA256 public key fingerprint ‘’
a. Generate configuration fingerprint:/consumer/cn/doc/harmonyos-guides/push-preparations-0000001727885250#section388942317518
b. Configure the certificate fingerprint:/consumer/cn/doc/app/agc-help-signature-info-0000001628566748#section5181019153511
You can focus on checking whether the certificate fingerprint configured by clientid and AGC platform is manually generated, and whether the certificate used during packaging is consistent with the configuration on the AGC platform;

The partition selection prompts map permissions, but map permissions have been enabled in the appGallery web page. What other permissions are needed?
Solution:
If permissions have been enabled, there may be a cache. You need to connect to the test device through the USB interface. Follow the steps below to configure and clear the cache:
1. Clear authentication cache
hdc shell rm -rf /data/service/el1/public/cloud_interface_auth/scopecache/*
2. Terminate the authentication process
hdc shell
ps -ef | grep auth, get the PID of cloud_interface_auth such as 34639
kill -9 34639, stop the SA process to clean the cache.
3. Clear demo and mapservice cache data and start testing
hdc shell bm clean -n application package name (such as) -d
hdc shell bm clean -n application package name (such as) -c
hdc shell bm clean -n -d
hdc shell bm clean -n -c

The call method report has no permission, but the background configuration has been checked, and the map cannot be displayed
Solution:
This error code means 1002600004. The third-party application does not have the permission to enable map service. It is recommended to check the following reasons:
1、/consumer/cn/doc/harmonyos-guides-V5/map-config-agc-V5 has the map service enabled
2. Check whether the client_id in module.json5 is consistent with the client_id in AppGallery Connect. If it is consistent, you can switch the phone back for 24 hours and try again
3. Whether it is manual signature:/consumer/cn/doc/harmonyos-guides-V5/application-dev-overview-V5
4. When configuring the value of client_id, you cannot configure it through the value in resource (such as $). Please write the value of client_id directly. For example: "value": "109920437"
