Question

我正在尝试将应用程序数据库保存到Google云端硬盘上的Apps文件夹中。我正在使用Drive v3 API。几个月前，一切正常，数据成功保存到用户appData文件夹中。但是目前，我正在获取GoogleAuthIOException。我的应用程序在Google控制台中具有所有必需的API密钥（oAuth，云端硬盘API）

这是我的代码：

首先，向用户显示一个对话框，以获取其帐户：

mCredential = GoogleAccountCredential.usingOAuth2(
        getApplicationContext(), Collections.singletonList(DriveScopes.DRIVE_APPDATA))
        .setBackOff(new ExponentialBackOff());
//...
startActivityForResult(
                    mCredential.newChooseAccountIntent(),
                    REQUEST_ACCOUNT_PICKER);
//...
if (resultCode == RESULT_OK && data != null &&
                    data.getExtras() != null) {
                String accountName =
                        data.getStringExtra(AccountManager.KEY_ACCOUNT_NAME);
                if (accountName != null) {
                    mCredential.setSelectedAccountName(accountName);
 }
}

接下来，我执行AsyncTask，检查文件夹中的当前文件（如果需要，将其删除）并在其中保存当前数据库。

我的AsyncTask类的完整列表：

private class MakeRequestTask extends AsyncTask<Boolean, Void, Boolean> {
    private com.google.api.services.drive.Drive mService;
    File databasePath;
    FileList fileList;

    MakeRequestTask(GoogleAccountCredential credential) {
        HttpTransport transport = AndroidHttp.newCompatibleTransport();
        JsonFactory jsonFactory = JacksonFactory.getDefaultInstance();
        mService = new com.google.api.services.drive.Drive.Builder(
                transport, jsonFactory, credential)
                .setApplicationName(getString(R.string.app_name))
                .build();
        databasePath = BackupActivity.this.getDatabasePath(databaseName);
    }


    @Override
    protected Boolean doInBackground(Boolean... params) {
        if (params[0]) {
            com.google.api.services.drive.model.File fileMetadata = new com.google.api.services.drive.model.File();
            fileMetadata.setName(databaseOnGDName);
            fileMetadata.setParents(Collections.singletonList("appDataFolder"));
            FileContent mediaContent = new FileContent("application/x-sqlite3", databasePath);
            try {
                fileList = mService.files().list().setSpaces("appDataFolder").execute(); //Here error appears
                if (fileList.getFiles().size() == 0) {
                    mService.files().create(fileMetadata, mediaContent).execute();
                } else {
                    for (com.google.api.services.drive.model.File file : fileList.getFiles()) {
                        mService.files().delete(file.getId()).execute();
                    }
                    mService.files().create(fileMetadata, mediaContent).execute();
                }
                return null;
            } catch (Exception e) {
                e.printStackTrace();
                return true;
            }
        } else {
            try {
                fileList = mService.files().list().setSpaces("appDataFolder").execute();
                for (com.google.api.services.drive.model.File file : fileList.getFiles()) {
                    if (file.getName().equals(databaseOnGDName)) {
                        File appDB = databasePath;
                        InputStream inputStream = mService.files().get(file.getId()).executeMediaAsInputStream();
                        OutputStream outputStream = new FileOutputStream(appDB);
                        IOUtils.copy(inputStream, outputStream);
                        inputStream.close();
                        outputStream.close();
                    }
                }
                return false;
            } catch (IOException e) {
                e.printStackTrace();
                return true;
            }
        }
    }
}

如何从错误中看到-身份验证问题。但是我所有的代码都来自Java的Google示例。如何解决此错误？

从理论上讲，我需要执行一些授权程序，但我的情况下找不到一个授权程序

Answer 1

好的，我终于找到了解决方法。

首先，当用户在此处选择其帐户时：

startActivityForResult(
                mCredential.newChooseAccountIntent(),
                REQUEST_ACCOUNT_PICKER);

我使用setSelectedAccount(account, "package")而非setSelectedAccountName(accountName)设置了所选帐户

我在AsyncTask中又添加了一个捕获，它创建了一个具有许可权限的对话框（如official documentation中所述）：

        try {

            fileList = mService.files().list().setSpaces("appDataFolder").execute();
            //...
            return null;
        } catch (UserRecoverableAuthIOException e) {
            e.printStackTrace();
            errorCode = 1;
            startActivityForResult(e.getIntent(), REQUEST_SIGNIN_REQUIRED);
            return true;
}

尝试在appDataFolder中获取文件列表时出现GoogleAuthIOException
