Cannot access Google Drive from 2 different device

问题

I have an app which creates a word file on the Google Drive with some text. If I try to access the word file on the Google Drive from the device In which I have created that file, then it works and everything thing goes smooth, and I can able to read and write. But If I try to access the same file with the same DriveId on the different device with the same app, then I can't access it. I have seen 2 related questions on the StackOverflow but I can't figure out the problem. Any help would be appreciated.

This is the GoogleApiClient Connection I am using:-

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

This is the program code:-

@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());
                    }

        }

};

This is the error message:-

回答1:

DriveId means nothing on a different device. If you want to work with a file/folder, on a different device you have to use the ResourceId. That's the old 'id' from RESTful API. DriveId is specific to one particular instance of Google Play Services*.

You can also search for files/folders using metadata like title, mime, parent, ... but! Only DriveId and ResourceId are unique IDs, everything else (including title) is not. That means you can have multiple files / folders of the same name in the same location on the Drive !

*) There is an attempt to explain this on SO 29030110 .

Good Luck
