我有一个应用程序,可以在Google Drive上创建一个带有文字的文字文件。如果我尝试从我创建该文件的设备访问Google Drive上的word文件,那么它可以工作,一切顺利,我能够读写。但是如果我尝试使用相同的应用程序在不同的设备上使用相同的DriveId访问同一个文件,那么我无法访问它。我在StackOverflow上看过2个相关问题,但我无法弄清楚问题。任何帮助,将不胜感激。

这是我正在使用的GoogleApiClient连接: -

    if(mGoogleApiClient == null)
    {
        mGoogleApiClient = new GoogleApiClient.Builder(this)
                .addApi(Drive.API)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .addScope(Drive.SCOPE_FILE)
                .build();
    }
    mGoogleApiClient.connect();

这是程序代码: -

@Override
public void onConnected(Bundle bundle) {
    msg.Log("onConnected");

            msg.Log(inputText.encodeToString());
            DriveFile file = Drive.DriveApi.getFile(mGoogleApiClient, inputText);
            file.open(mGoogleApiClient, DriveFile.MODE_READ_ONLY, null).setResultCallback(contentsOpenedCallBack);
}

final private ResultCallback<DriveApi.DriveContentsResult> contentsOpenedCallBack = new ResultCallback<DriveApi.DriveContentsResult>() {
    @Override
    public void onResult(DriveApi.DriveContentsResult driveContentsResult) {

        msg.Log("onResult");
        msg.Log("toString ");
        if (!driveContentsResult.getStatus().isSuccess()) {
            Toast.makeText(getBaseContext(), "Wrong Success", Toast.LENGTH_SHORT).show();

        }

            final DriveContents contents = driveContentsResult.getDriveContents();


                    BufferedReader reader = new BufferedReader(new InputStreamReader(contents.getInputStream()));
                    StringBuilder builder = new StringBuilder();
                    String line;

                    try {
                        while ((line = reader.readLine()) != null) {
                            builder.append(line);
                        }
                    } catch (IOException e) {
                        msg.Log(e.toString());
                    }

                    String contentsAsString = builder.toString();

                    try {
                        JSONObject json = new JSONObject(contentsAsString);

                        String Text = json.getString("text");


                        SharedPreferences sp = getSharedPreferences("Font", Context.MODE_PRIVATE);
                        SharedPreferences.Editor editor = sp.edit();
                        editor.putString("value", Text);
                        msg.Log(Password);


                    } catch (Exception e) {
                        msg.Log(e.toString());
                    }

        }

};

这是错误消息: -

DriveId 在其他设备上没有任何意义。如果要使用文件/文件夹,则必须使用 ResourceId 在其他设备上。这是RESTful API中的旧'id'。 DriveId特定于Google Play Services *的一个特定实例。

您还可以使用title,mime,parent等元数据搜索文件/文件夹,但是!只有DriveId和ResourceId是唯一ID,其他所有(包括标题)都不是。这意味着您可以在云端硬盘上的同一位置拥有多个同名文件/文件夹!

*)试图在SO 29030110上解释这一点。
