无法覆盖 Google Drive AppData 文件夹 INTERNAL_ERROR 中的文件

Question

我在我的应用程序中使用 GDAA 来管理 google 驱动器中的应用程序文件。下面列出的所有操作都可以正常工作，例如

• google 登录（为 AppData 文件夹添加范围）
• 从 AppData Folder
下载文件
• 上传文件到AppData Folder
• 从 AppData Folder
中删除文件

但是当我尝试覆盖 AppData Folder 中的文件时，我在 [=19] 中收到 后续错误 =]回调。

Status Message : Failed to commit changes. 
Status Code : INTERNAL_ERROR (8)

我不明白为什么会这样。请在下面找到我的代码以供参考

public void overwrite(String strLocalFilePath, String strDriveId, String strGoogleDriveFileMimeType, String strGoogleDriveFileTitle){
    final DriveId driveId = DriveId.decodeFromString(strDriveId);
    DriveFile file = driveId.asDriveFile();

    file.open(mGoogleApiClient, DriveFile.MODE_WRITE_ONLY, null).setResultCallback(new ResultCallback<DriveApi.DriveContentsResult>() {
        @Override
        public void onResult(DriveApi.DriveContentsResult result) {
            if (!result.getStatus().isSuccess()) {
                Log.e(TAG,"Error");
                return;
            }

            DriveContents driveContents = result.getDriveContents();
            OutputStream outputStream = driveContents.getOutputStream();
            boolean isSuccess = writeFileToStream(outputStream, strLocalFilePath);

            if (isSuccess) {
                MetadataChangeSet changeSet = new MetadataChangeSet.Builder()
                        .setTitle(strGoogleDriveFileTitle)
                        .setMimeType(strGoogleDriveFileMimeType)

                driveContents.commit(mGoogleApiClient, changeSet, executionOptions).setResultCallback(new ResultCallback<Status>() {

根据此 ，如果您收到错误代码 8 (INTERNAL_ERROR)，请仔细检查您在开发控制台中的应用注册。请注意，每个注册的 Android 客户端都由（包名称，Android 签名证书 SHA-1）对唯一标识。如果您的调试和生产环境有多个包名称/签名证书，请确保注册每一对。

To verify:

1. Open the Credentials page and select your project
2. Make sure every pair has an Android typed OAuth 2.0 client IDs. To create a new OAuth 2.0 client ID for your Android client, select New Credentials->OAuth2 Client ID from the dropdown, select Android and input your Package name / Signing-certificate fingerprint there.

To get your signing key certificate SHA-1:

Standard Debug Key

keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android

Other (Custom) Key

keytool -list -v -keystore $YOUR_KEYSTORE_LOCATION

这里有一个可能也有帮助的参考：

• Error : ConnectionResult{statusCode=INTERNAL_ERROR, resolution=null}

If you are getting this bug even after 1) making sure that you have registered the package name with its corresponding certificate fingerprint, and 2) are (re)using an already existing project, then you should check that this project has an product name and an email address (double check that one specially) associated with it, both to be found in the "consent screen" section.
