Eu gastei muito tempo nisso, então gostaria de perguntar sobre isso. Quero criar e fazer upload da planilha do Google usando o Android. Eu sei que devo usarAPI do Drive para fazer isso. Eu sei como criar arquivo usando essa API (mesmo arquivo excel), mas quandosetMimeType está configurado paraapplication / vnd.google-apps.spreadsheet Eu recebo um erro no dispositivo:Erro ao tentar criar o arquivo.

    @Override
public void onConnected(Bundle connectionHint) {
    super.onConnected(connectionHint);
    // create new contents resource
    Drive.DriveApi.newDriveContents(getGoogleApiClient())
            .setResultCallback(driveContentsCallback);
}

final private ResultCallback<DriveContentsResult> driveContentsCallback = new
        ResultCallback<DriveContentsResult>() {
            @Override
            public void onResult(DriveContentsResult result) {
                if (!result.getStatus().isSuccess()) {
                    showMessage("Error while trying to create new file contents");
                    return;
                }
                final DriveContents driveContents = result.getDriveContents();

                // Perform I/O off the UI thread.
                new Thread() {
                    @Override
                    public void run() {
                        // write content to DriveContents
                        OutputStream outputStream = driveContents.getOutputStream();
                        Writer writer = new OutputStreamWriter(outputStream);
                        try {
                            writer.write("Hello World!");
                            writer.write("Hello World!");
                            writer.close();
                        } catch (IOException e) {
                            Log.e(TAG, e.getMessage());
                        }

                        MetadataChangeSet changeSet = new MetadataChangeSet.Builder()
                                .setTitle("Orders")
                                .setMimeType("application/vnd.google-apps.spreadsheet")
                                .setStarred(true).build();



                        // create a file on root folder
                        Drive.DriveApi.getRootFolder(getGoogleApiClient())
                                .createFile(getGoogleApiClient(), changeSet, driveContents)
                                .setResultCallback(fileCallback);
                    }
                }.start();
            }
        };

final private ResultCallback<DriveFileResult> fileCallback = new
        ResultCallback<DriveFileResult>() {
            @Override
            public void onResult(DriveFileResult result) {
                if (!result.getStatus().isSuccess()) {
                    showMessage("Error while trying to create the file");
                    return;
                }
                showMessage("Created a file with content: " + result.getDriveFile().getDriveId());
                storeId(result.getDriveFile().getDriveId());
                kill_activity();
            }
        };v
