Crash (AppGallery Connect) Quick Start

Crash Service of AppGallery Connect is a lightweight crash analysis service, in which Huawei provides a Crash SDK that can be quickly integrated into your app, without the need for coding.


  • The Crash service provides real-time reports for the last 24 hour, allowing you to monitor the quality of your app in real time.

  • In addition, the Crash service automatically categorizes crashes, and provides indicator data of the crashes, allowing you to prioritize the most important crashes. You can view information about a specific crash, and analyze the app and Android versions with the crash. You can also view information about the app, operating system, and device corresponding to a specific crash, as well as the crashed stack. All the information is enormously helpful in locating and resolving crashes.

  • The Crash service can also detect major crashes in real time. After you enable crash notifications, AppGallery Connect can send you an email when a major crash occurs.

Version Update Description

  • Latest Version: 0.5.5_1.4.1.300

    • Update the SDK and fix some bugs.
  • v0.5.3_1.3.2

    • Integrated Huawei AGC Crash service.

Enable Crash Service

  • Use Cocos Creator to open the project that needs to be connected to Crash service.

  • Since the Crash service uses the HUAWEI Analytics Kit to report crash event, please enable the Analytics Kit (HMS Core) before integrating the Crash service.

  • Click on Panel -> Service in the menu bar to open the Service panel, select Crash service to go to the service detail page, and then click on the Enable button in the top right to enable the service. For details, please refer to the Cocos Service Operation Guide documentation.

Configs HUAWEI Config File

Most of HUAWEI Services need the agconnect-services.json configuration file. If there are operations such as newly opened services, please update the file in time.

  • Sign in to AppGallery Connect find your project from the project list and select the app on the project card.

  • On the Project Setting page, click the configuration file agconnect-services.json to download it. The agconnect-services.json file must be copied manually to the settings directory of the project directory after downloading or updating.

  • For Creator v2.4.3 and above, if you want to publish to the HUAWEI AppGallery Connect, you can select the downloaded or updated configuration file directly in the Build panel, no need to copy it manually.

Verify whether the service is integrated successfully

Generally, there is a low probability of an app crashing, so the Crash service SDK provides a method to manually create a crash, which can be invoked to determine if the Crash service was successfully accessed.

  • Add simple code to the script.

    console.log("Call crash method after 5 seconds.");
  • You can publish to the Android platform after the code is added. Please make sure that the Package Name on the Build panel is consistent with the Package Name set in the AppGallery Connect console.

  • Run the project on a phone, then login the AppGallery Connect console, open the project, go to Quality -> Crash. If you can see crash data (usually displayed within 5 minutes), which means the integrate is successful.

Sample Project

Developer can get a quick taste of the Crash service with the sample project.

  • Click on the Sample button in the Crash service panel, clone or download, and open the project in Cocos Creator.

  • After enabling the Crash service and configuring the HUAWEI configuration file as described above, you can open the Build panel to compile the project by clicking Project -> Build in the Creator editor menu bar. Cocos Creator v2.4.1 and above, you could publish to HUAWEI AppGallery Connect. Below Creator v2.4.1 could publish to the Android platform.

  • Once the Sample project is running on the phone, click the Crash button on the homepage for testing.
