Question

Google Drive API新手，似乎无法阅读Google Doc文件的内容。我能够读取元数据，但文件不会打开＆＃34;。我得到此错误代码10，状态{statusCode =此文件无法打开。，resolution = null}。如何访问Google文档的内容？

＆＃13;

private void open() {
        Log.w(TAG, mSelectedFileDriveId.getResourceId());
        DriveFile driveFile = mSelectedFileDriveId.asDriveFile();

        driveFile.getMetadata(mGoogleApiClient).setResultCallback(new ResultCallbacks<DriveResource.MetadataResult>() {
            @Override
            public void onSuccess(@NonNull DriveResource.MetadataResult metadataResult) {
                Log.w(TAG, "Title: "+ metadataResult.getMetadata().getTitle());
                Log.w(TAG, "Filename: "+ metadataResult.getMetadata().getOriginalFilename());
                Log.w(TAG, "MimeType: "+ metadataResult.getMetadata().getMimeType());
                Log.w(TAG, "DriveId: "+ metadataResult.getMetadata().getDriveId());
                Log.w(TAG, "Description: "+ metadataResult.getMetadata().getDescription());
            }

            @Override
            public void onFailure(@NonNull Status status) {
                Log.w(TAG, "Failed to get metadata");
            }
        });

        driveFile.open(mGoogleApiClient, DriveFile.MODE_READ_ONLY, null).setResultCallback(driveContentsResultResultCallbacks);
        mSelectedFileDriveId = null;
    }

＆＃13;

private final ResultCallbacks<DriveApi.DriveContentsResult> driveContentsResultResultCallbacks = new ResultCallbacks<DriveApi.DriveContentsResult>() {
        @Override
        public void onSuccess(@NonNull DriveApi.DriveContentsResult driveContentsResult) {
            Log.i(TAG, "File contents opened");

            // Read from the input stream an print to LOGCAT
            DriveContents driveContents = driveContentsResult.getDriveContents();
            BufferedReader reader = new BufferedReader(new InputStreamReader(driveContents.getInputStream()));
            StringBuilder builder = new StringBuilder();
            String line;
            try {
                while ((line = reader.readLine()) != null) {
                    builder.append(line);
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
            String contentsAsString = builder.toString();
            Log.i(TAG, contentsAsString);

            // Close file contents
            driveContents.discard(mGoogleApiClient);
        }

        @Override
        public void onFailure(@NonNull Status status) {
            Log.w(TAG, "Error while opening the file contents");
            Log.w(TAG, "Status: "+status.getStatus());
            Log.w(TAG, "Status Code: "+status.getStatusCode());
            Log.w(TAG, "Status Message: "+status.getStatusMessage());
