How I can create and upload google spreadsheet using android app?

Question

I have spent too much time on this so I would like to ask about it. I want to create and upload google spreadsheet using android. I know that I should use Drive API to do this. I know how to create file using this API(even excel file) but when setMimeType is set to application/vnd.google-apps.spreadsheet I receive an error on the device: Error while trying to create the file.

    @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

The GDAA does not currently support creation Google Docs files. You will have to use the Google Drive REST API in your Android application to do this.

@user3212019, You can upload a excel spread sheet in google drive from your android app, just follow as below.

I think you aware of Quick Start on Google Android site.

Now create a excel sheet by using jxl jar library

Now follow the Start Integrating Google Sign-In and Integrate Google SignIn with Drive scope (Drive.SCOPE_FILE) in your app.

Now final and last copy paste below activity code in your activity and then give a excel sheet path in saveFileToDrive(file_path) method.

public class UploadFileInGoogleDriveActivity extends Activity {

    private static final String TAG = "tejadroid-quickstart";
    private static final int REQUEST_CODE_SIGN_IN = 0;

    private GoogleSignInClient mGoogleSignInClient;
    private DriveClient mDriveClient;
    private DriveResourceClient mDriveResourceClient;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        signIn();
    }

    /**
     * Start sign in activity.
     */
    private void signIn() {
        Log.i(TAG, "Start sign in");
        mGoogleSignInClient = buildGoogleSignInClient();
        startActivityForResult(mGoogleSignInClient.getSignInIntent(), REQUEST_CODE_SIGN_IN);

    }

    /**
     * Build a Google SignIn client.
     */
    private GoogleSignInClient buildGoogleSignInClient() {
        GoogleSignInOptions signInOptions =
                new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
                        .requestScopes(Drive.SCOPE_FILE)
                        .build();
        return GoogleSignIn.getClient(this, signInOptions);
    }

    @Override
    protected void onActivityResult(final int requestCode, final int resultCode, final Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        switch (requestCode) {
            case REQUEST_CODE_SIGN_IN:
                Log.i(TAG, "Sign in request code");
                // Called after user is signed in.
                if (resultCode == RESULT_OK) {
                    Log.i(TAG, "Signed in successfully.");
                    // Use the last signed in account here since it already have a Drive scope.
                    mDriveClient = Drive.getDriveClient(this, GoogleSignIn.getLastSignedInAccount(this));
                    // Build a drive resource client.
                    mDriveResourceClient =
                            Drive.getDriveResourceClient(this, GoogleSignIn.getLastSignedInAccount(this));

                    // Excel Sheet path from SD card
                    final String filePath = "/storage/emulated/0/Expense Manager/ExpenseReport/ExpenseDiary.xls";
                    saveFileToDrive(filePath);
                }
                break;
        }
    }

    /**
     * Create a new file and save it to Drive.

        OutputStream outputStream = driveContents.getOutputStream();
        InputStream in = new FileInputStream(file);
        try {

                            @Override

                            }
                        });
    }


}

Just debug app and look in to Google Drive there your file exist in root folder of drive.
