Your question is:

How do I upload a newer version of a Release APK into AppGallery
correctly?

First, you have already downloaded APK with the URL. Please make sure the Updating App File Information invoked within 5 minutes. Because the uploaded file is only available for 5 minutes before calling the Updating App File Information API.

Second, please perform the following steps to upload the newer version:

1. Step One: Obtaining the File Upload URL: This API is used to obtain the upload URLs of files including images, videos, and APK, RPK, and PDF files when developers need to upload these files.

2. Step Two: Uploading Files：This API is used to upload files from a client or server to the file server.

3. Step Three: Updating App File Information: This API is used to update app file information after images, videos, and APK and RPK files are uploaded.

4. Step Four: Submitting an App for Release: This API is used to submit a request for app approval. Before calling this API, ensure that the app information is complete and the app software package has been uploaded.

You can check whether the above two parts have solved your problem.

I’ve got a project set up at Huawei AppGallery and want to make a Gradle plugin that uploads a new version of a Release APK file into the project without submitting it for approval, using Huawei Connect API (just upload a new version, not publish actual update to the users). Right now there is an older version of the android apk at HuaweiAppGallery.

This is what I’ve got so far. With huaweiService instance it just calls endpoints of Connect API:

    // get access token
    val token = huaweiService.getToken(
        clientId = clientId,
        clientSecret = clientSecret
    )

    // get app id
    val appInfo = huaweiService.getAppID(
        clientId = clientId,
        token = token,
        packageName = variant.applicationId
    )
    
    val uploadUrl = huaweiService.getUploadApkUrl(
        clientId = clientId,
        token = token,
        appId = appInfo.value
    )

    // upload apk file
    val fileInfoListResult = huaweiService.uploadApkFile(
        uploadUrl = uploadUrl.uploadUrl,
        authCode = uploadUrl.authCode,
        apkFile = apkFile
    )

    // update app info
    val fileInfoRequestList = mapFileInfo(fileInfoListResult, apkFileName)
    val appId = appInfo.value
    huaweiService.updateAppFileInformation(
        clientId = clientId,
        token = token,
        appId = appId,
        fileInfoRequestList = fileInfoRequestList
    )

The issues I’ve run into are:

1. APK file upload request actually succeeds, uploadApkFile returns a download url inside a result (I can even download APK with this url), but this APK file is not appearing inside Huawei AppGallery, where all APK versions of the app appear when I load them manually. So I can’t submit it for release approval.

2. updateAppFileInformation method executed after uploading APK fails with error:

   [cds]add apk failed, additional msg is [package name already exists]
   

Why is it telling me that package name already exists? I know that it does, there is an older version of my app already uploaded, which I just want to update.
Ho do I upload a newer version of a Release APK into AppGallery correctly so that I could take it and submit for release manually after that?
