I am trying to add map style to Huawei map for my app. I had made a JSON file for style from Huawei map style editor and use it in setMapStyle method by MapStyleOptions.loadRawResourceStyle and passing the JSON file. I used huawei simple map and add some custom style to it. When I first open the app then the default map (simple) is loaded and the custom styles from JSON is not applied, but I go back to the previous screen and again launch the map screen then the style from JSON is properly applied. How to solve the problem for the first time launch?

First you can follow this development documents all Steps:
setMapStyle method by MapStyleOptions.loadRawResourceStyle and passing the JSON file, this is load the local map.
To fix the problem need to change the cloud load mapstyle , see the above docs's Step 5:
Using a custom style after a map is created
Call the setStyleId and previewId methods in HuaweiMap to use a custom map style.
The sample code is as follows:
HuaweiMap hMap;
// Specify a style ID after a map is created.
hMap.setStyleId(String styleId);
// Specify a preview ID after a map is created.
hMap.previewId(String previewId);
Using a custom style before a map is created
Call the styleId and previewId methods in HuaweiMapOptions to use a custom map style. If both styleId and previewId are set, styleId takes precedence.
The sample code is as follows:
HuaweiMapOptions huaweiMapOptions;
// Specify a style ID before a map is created.
huaweiMapOptions.styleId(String styleId);
// Specify a preview ID before a map is created.
huaweiMapOptions.previewId(String previewId);
use method above will change the cloud map for the first time.
