登录到Android上的谷歌驱动器,而无需将谷歌帐户添加到设备

Question

我开发了一个Android应用程序,需要允许对用户的谷歌驱动器进行读/写访问.此外,它应该在公共设备上运行(意味着许多人可能使用相同的设备访问他们的谷歌驱动器帐户).在这种情况下,将每个用户的帐户添加到Android帐户管理器是不可接受的.不幸的是,所有官方指南都使用在设备上注册的Google帐户进行身份验证.将显示从设备中选择现有Google帐户或添加新帐户的弹出窗口.

protected void onStart() {
        super.onStart();
        if (mGoogleApiClient == null) {
            mGoogleApiClient = new GoogleApiClient.Builder(this)
                    .addApi(Drive.API)
                    .addScope(Drive.SCOPE_FILE)
                            // Optionally, add additional APIs and scopes if required.
                    .addConnectionCallbacks(this)
                    .addOnConnectionFailedListener(this)
                    .build();
        }
        mGoogleApiClient.connect();
    }



    /**
     * Called when {@code mGoogleApiClient} is trying to connect but failed.
     * Handle {@code result.getResolution()} if there is a resolution
     * available.
     */
    @Override
    public void onConnectionFailed(ConnectionResult result) {
        Log.i(TAG, "GoogleApiClient connection failed: " + result.toString());
        if (!result.hasResolution()) {
            // Show a localized error dialog.
            GooglePlayServicesUtil.getErrorDialog(
                    result.getErrorCode(), this, 0, new OnCancelListener() {
                        @Override
                        public void onCancel(DialogInterface dialog) {
                            retryConnecting();
                        }
                    }).show();
            return;
        }
        // If there is an existing resolution error being displayed or a resolution
        // activity has started before, do nothing and wait for resolution
        // progress to be completed.
        if (mIsInResolution) {
            return;
        }
        mIsInResolution = true;
        try {
            result.startResolutionForResult(this, REQUEST_CODE_RESOLUTION);
        } catch (SendIntentException e) {
            Log.e(TAG, "Exception while starting resolution activity", e);
            retryConnecting();
        }
    }

解决方法是什么？我需要在不保存设备帐户的情况下登录谷歌帐户(实际上只能访问驱动器).我只需要在完成后登录并注销,而不会在设备上留下任何个人信息.我该怎么做？

这不可能。只有在设备上注册的帐户（由用户自己验证）才能选择/使用连接到 GooDrive。即使您可以使用如下构造：

mGoogleApiClient = new GoogleApiClient.Builder(this)
                    .addApi(Drive.API)
                    .addScope(Drive.SCOPE_FILE)
                            // Optionally, add additional APIs and scopes if required.
                    .addConnectionCallbacks(this)
                    .addOnConnectionFailedListener(this)
                    .setAccountName([SOME_EMAIL@GMAIL.COM])
                    .build();

（请注意.setAccountName([SOME_EMAIL@GMAIL.COM])），电子邮件仍然必须是设备注册帐户之一。该应用程序无法处理用户未经身份验证的任何帐户，这将是安全禁忌，对吗？

祝你好运
