如何将文件上传到Google云端硬盘在android系统 [英] How to upload a file to GoogleDrive in android
问题描述
我从这个code参照
AccountManager am = AccountManager.get(activity);
am.getAuthToken(am.getAccounts())[0],
"oauth2:" + DriveScopes.DRIVE,
new Bundle(),
true,
new OnTokenAcquired(),
null);
private class OnTokenAcquired implements AccountManagerCallback<Bundle> {
@Override
public void run(AccountManagerFuture<Bundle> result) {
try {
final String token = result.getResult().getString(AccountManager.KEY_AUTHTOKEN);
HttpTransport httpTransport = new NetHttpTransport();
JacksonFactory jsonFactory = new JacksonFactory();
Drive.Builder b = new Drive.Builder(httpTransport, jsonFactory, null);
b.setJsonHttpRequestInitializer(new JsonHttpRequestInitializer() {
@Override
public void initialize(JSonHttpRequest request) throws IOException {
DriveRequest driveRequest = (DriveRequest) request;
driveRequest.setPrettyPrint(true);
driveRequest.setKey(CLIENT ID YOU GOT WHEN SETTING UP THE CONSOLE BEFORE YOU STARTED CODING)
driveRequest.setOauthToken(token);
}
});
final Drive drive = b.build();
final com.google.api.services.drive.model.File body = new com.google.api.services.drive.model.File();
body.setTitle("My Test File");
body.setDescription("A Test File");
body.setMimeType("text/plain");
final FileContent mediaContent = new FileContent("text/plain", an ordinary java.io.File you'd like to upload. Make it using a FileWriter or something, that's really outside the scope of this answer.)
new Thread(new Runnable() {
public void run() {
try {
com.google.api.services.drive.model.File file = drive.files().insert(body, mediaContent).execute();
alreadyTriedAgain = false; // Global boolean to make sure you don't repeatedly try too many times when the server is down or your code is faulty... they'll block requests until the next day if you make 10 bad requests, I found.
} catch (IOException e) {
if (!alreadyTriedAgain) {
alreadyTriedAgain = true;
AccountManager am = AccountManager.get(activity);
am.invalidateAuthToken(am.getAccounts()[0].type, null); // Requires the permissions MANAGE_ACCOUNTS & USE_CREDENTIALS in the Manifest
am.getAuthToken (same as before...)
} else {
// Give up. Crash or log an error or whatever you want.
}
}
}
}).start();
Intent launch = (Intent)result.getResult().get(AccountManager.KEY_INTENT);
if (launch != null) {
startActivityForResult(launch, 3025);
return; // Not sure why... I wrote it here for some reason. Might not actually be necessary.
}
} catch (OperationCanceledException e) {
// Handle it...
} catch (AuthenticatorException e) {
// Handle it...
} catch (IOException e) {
// Handle it...
}
}
}
在jsonHtt prequestInitializer我得到一个问题。 [GoogleClient $ Builder无法得到解决。这是间接需要的.class文件中引用]请建议我什么，我必须做的......
In jsonHttpRequestInitializer i get an issues. [GoogleClient$Builder cannot be resolved. It is indirectly referenced from required .class files] please suggest me what i have to do...
推荐答案
您有两个不同的API，你可以在Android使用的的 REST 和 GDAA 。
You have two different APIs you can use on Android, the REST and the GDAA.
剩下的就是准系统的API，让你谷歌驱动器的全部功能。你也有一个互动的操场上测试一切（见此页）。但是你要管理网络延误，故障，等...你自己。理想情况下，你会委派工作同步适配器服务。
REST is the 'barebones' API that gives you the full functionality of Google Drive. You also have an interactive playground to test everything (see the bottom of this page). But you have to manage the network delays, failures, etc... yourself. Ideally you would delegate that work to sync adapter service.
GDAA是建立在REST之上，居住在谷歌播放服务，其行为与延迟推广对象（文件夹/文件）驱动器的本地API。有比剩下的只有有限的功能（忘了缩略图的链接，等等）。从本质上讲，你跟GDAA和GDAA会谈，就它自己的时间安排驱动器。所以，你不必担心在线/离线的情况。不过要小心，这也可能会导致同步问题，因为你没有对对象的推广时机直接控制。对于GDAA的演示可以在这里找到 和的此处。
GDAA is built on top of REST, resides in Google Play Services and behaves as a local API with delayed promotion of objects (folders/files) to the Drive. Has only limited functionality compared to REST (forget thumbnail link, etc...). Essentially, you talk to GDAA and GDAA talks to the Drive on it's own schedule. So, you don't have to worry about on-line / off-line situations. Be careful though, this may also cause synchronization issues, since you don't have direct control over object promotion timing. The demos for GDAA can be found here and here.
我也创建了一个简单的 CRUD演示应用，你可以逐步。在create（）方法有你问所在的上传。它不完全了最新的，因为GDAA先后实施了垃圾的功能已经（在谷歌Play服务的7.00 / 23修订版）。
I've also created a simple CRUD demo app that you can step through. The upload you're asking resides in create() method there. It is not fully up-to-date, since GDAA has implemented the 'trash' functionality already (in Google Play Services 7.00 / Rev. 23).
