Question

我尝试将我的应用程序连接到Google Play服务以访问Google云端硬盘，但它显示连接失败，带有statusCode SIGN_IN_REQUIRED.

但它似乎就在3天前表现得那样。我也检查了谷歌的开发者控制台。他们可能在API中改变了一些我无法弄清楚的东西。欢迎您的帮助。

我的代码：

/**
 * Create a new file and save it to Drive.
 */
    private void saveFileToDrive(final byte[] data) {
    // Start by creating a new contents, and setting a callback.
    Log.i(TAG, "Creating new contents.");
    //final Bitmap image = mBitmapToSave;
    Drive.DriveApi.newDriveContents(mGoogleApiClient)
            .setResultCallback(new ResultCallback<DriveApi.DriveContentsResult>() {

                @Override
                public void onResult(DriveApi.DriveContentsResult result) {
                    // If the operation was not successful, we cannot do anything
                    // and must
                    // fail.
                    if (!result.getStatus().isSuccess()) {
                        Log.i(TAG, "Failed to create new contents.");
                        return;
                    }
                    // Otherwise, we can write our data to the new contents.
                    Log.i(TAG, "New contents created.");
                    // Get an output stream for the contents.
                    OutputStream outputStream = result.getDriveContents().getOutputStream();
                    // Write the bitmap data from it.
                   /* ByteArrayOutputStream bitmapStream = new ByteArrayOutputStream();
                    image.compress(Bitmap.CompressFormat.PNG, 100, bitmapStream);*/
                    try {
                        //outputStream.write(bitmapStream.toByteArray());
                        outputStream.write(data);
                    } catch (IOException e1) {
                        Log.i(TAG, "Unable to write file contents.");
                    }
                    // Create the initial metadata - MIME type and title.
                    // Note that the user will be able to change the title later.
                    MetadataChangeSet metadataChangeSet = new MetadataChangeSet.Builder()
                            .setMimeType("application/pdf").setTitle(filename).build();
                    // Create an intent for the file chooser, and start it.
                    IntentSender intentSender = Drive.DriveApi

                    }

Logcat消息：

Answer 1

我收到了LogCat中显示的消息：

GoogleApiClient onConnectionFailed with statusCode = SIGN_IN_REQUIRED

登录需要表示我们需要启用Google Drive API https://console.developers.google.com

下载client_id.json文件并添加到项目的/app文件夹中：

然后我们可以毫无问题地访问，以获得我们预期的 API client connected. ：

为了更好地使用Google Drive API，建议使用以下权限：

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.GET_ACCOUNTS" />

您可以在此处找到完整的示例：

Answer 2

Here是您收到的错误的信息。我假设您是，但您需要登录才能访问云端硬盘。当我运行示例应用程序时，它一开始就要求我选择一个帐户。也许您没有与您使用的设备同步的帐户？可以选择＆＃34;添加帐户＆＃34;，但是当您拥有零帐户时，行为可能会有所不同。文档建议你继续不使用API（只是因为你不能登录）或调用startResolutionForResult（Activity，int）来提示用户登录，但最简单的方法是添加{{3 }}

Answer 3

此错误表示帐户已被锁定，可能是出于安全原因。在尝试通过Android应用程序以编程方式访问帐户之前，您应该从桌面浏览器转到drive.google.com并登录帐户。一旦您完成了桌面浏览器登录，您就可以从Android访问该帐户。

Answer 4

这将在您创建Google API项目后生效，您已按要求添加了SHA-1和包名称。另外，请记住，您的软件包不得与Google中的其他项目冲突。希望这有效。在以下位置注册您的项目：

Click here to add enable your Google api

并在项目凭据全部设置后启用API。如果您要上传或下载文件，则必须在清单文件中使用权限：

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

-Surajit。快乐的编码。

Answer 5

正如我所看到的大部分答案都是对的，如果你无法解决问题的话。以下是请与您的开发环境一起检查的事项

如果您已在两个不同的系统（个人电脑/笔记本电脑）之间切换，请为每个系统生成另一个SHA1密钥，并在Google开发者控制台上进行更新
如果您仍然没有在两个系统之间切换，那么请确保您的清单应用ID 与您提供的包名相匹配在Google开发者控制台中
请勿忘记在Google开发者控制台中启用Drive API

Answer 6

我遇到同样的问题并花了很多时间来修复

也许您没有将您的电子邮件添加到Google控制台上的测试人员列表，也可能是您使用其他帐户登录的设备Google Play游戏应用，因此请将其添加到测试人员帐户并再试一次
