List files from Google Drive and get downloadUrl for selected file in Android

I am trying to show a list of files the user has on their Google Drive from my Android app and once the user has selected a file, I want to get the downloadUrl and the Bearer token for that account to give it to my application server to download it.
I have been looking around and it seems very confusing. There are 2 SDKs, Android SDK and Java SDK (REST based) for Google Drive.
I successfully was able to get the list of files and display it using the Android SDK (I did not have to build any UI), and when the user selects a file, I got all the metadata about the file but the downloadUrl. I did get some links like the webContentLink and the alternateLink, but it turns out that because the file was not shared, I cannot pass these links to my server to download it.
Upon some more research I found out that the downloadUrl is accessible by using the Java SDK. My question is, do I have to build my own UI to display a list of files I obtain? How do I handle the folder hierarchy if I have to build my UI to show these files?
Below is the code which prints the data about the File. I have implemented this code based on the tutorial.

EDIT: Please see my answer (not the accepted one) for a working sample. The use case is: list all the Google Drive files for the user and when selected one, get the downloadUrl and the access_token for the file.

In order to use the file/folder outside of your GDAA based app, you need so-called ResourceID. This ResourceId is a string that uniquely identifies the object of Google Drive (see here)
Turn DriveId into ResourceId:
DriveId driveId = metadata.getDriveId();
String resourceId = driveId.getResourceId();
Once you have ResourceId, you can construct 'download URL' for your server app from it. The ResourceID string is the one found if you go to drive.google.com, select a file/folder and perform rightbutton > getLink.
(looks like 'https://drive.google.com/open?id=0B1mQUW2__I_am_the_resource_id')
Just take this string '0B1mQUW2__I_am_the_resource_id' to the 'TryIt' playground here and paste it to the 'fileId' field.
So, the short answer is that you don't need RESTful Api to get the file/folder identifier you can use elsewhere.
Second part of your question, 'How do I handle the folder hierarchy if I have to build my UI to show these files?' is answered (somewhat) in the 'createTree()/testTree()' methods of MainActivity of these 2 demos (GDAADemo, RESTDemo). These are the same tasks implemented on the GDAA as well as the REST Apis and the choice depends mainly on the SCOPE your app needs (GDAA supports only the FILE scope, whereas REST supports both the FILE and the DRIVE scopes)
Good Luck

Android Google Play Services returns invalid token for blogger api

I've been given access to the blogger API, I've confirmed that on my developer console.
I've also written some code to perform oAuth2 with Google Play Services using some of the code below.
String SCOPE ="oauth2:https://www.googleapis.com/auth/blogger";
GoogleAuthUtil.getToken(context, "myEmail#gmail.com", mScope);
It returns a token. As it should.
However, once I try to access the api using the token i get a error.

I've been banging my head against the wall on this one. Anyone have any ideas?

Finally figured it out.
My build.gradle file somehow ended up having a different Application ID than my manifest. I changed it so they both match the manifest, and boom! it worked.

Stuck in Connection Failed loop with GoogleApiClient

I am trying to implement the com.google.android.gms.common.api.GoogleApiClient in my project.
The problem is that every time I try to connect, I get the call back to the onConnectionFailed listener with a pending intent that I execute. On a clean install, the very first pending intent will launch an account select screen. This is expected. Every subsequent restart of the app will bypass the account selection, unless the app's data is cleared in the Application Manager.
After the account-select screen, the signing-in screen will appear breifly. It never signs in though. The onActivityResult will be called after the signing-in screen flashes, which tries to connect the client. It doesn't connect, and calls the onConnectionFailed listener again.
If I keep trying to execute the intents, I get stuck in loop with the signing in screen breifly appearing, then disappearing, but never connecting or getting signed in. The ConnectionResult.toString indicates "Sign_In_Required", and returns an error code of 4 (the same as the Sign_In_Required constant.
On the API console, I've implemented an Ouath 2.0 client ID, and a public API access key for android applications. Notably, my app works using the older com.google.api.services.drive.Drive client.
As for my code:
I've tried using two different implementations here and here. I tried to implement the second example making as few changes as possible. It is reproduced below:
public class MainActivity extends Activity implements ConnectionCallbacks,
OnConnectionFailedListener {
private static final String TAG = "android-drive-quickstart";
private static final int REQUEST_CODE_CAPTURE_IMAGE = 1;
private static final int REQUEST_CODE_CREATOR = 2;
private static final int REQUEST_CODE_RESOLUTION = 3;
private GoogleApiClient mGoogleApiClient;
private Bitmap mBitmapToSave;
/**
* Create a new file and save it to Drive.
*/
private void saveFileToDrive() {
// Start by creating a new contents, and setting a callback.
Log.i(TAG, "Creating new contents.");
final Bitmap image = mBitmapToSave;
Drive.DriveApi.newContents(mGoogleApiClient).setResultCallback(new ResultCallback<DriveApi.ContentsResult>() {
#Override
public void onResult(DriveApi.ContentsResult 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.getContents().getOutputStream();
// Write the bitmap data from it.
ByteArrayOutputStream bitmapStream = new ByteArrayOutputStream();
image.compress(Bitmap.CompressFormat.PNG, 100, bitmapStream);
try {
outputStream.write(bitmapStream.toByteArray());
} 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("image/jpeg").setTitle("Android Photo.png").build();
// Create an intent for the file chooser, and start it.
IntentSender intentSender = Drive.DriveApi
.newCreateFileActivityBuilder()
.setInitialMetadata(metadataChangeSet)
.setInitialContents(result.getContents())
.build(mGoogleApiClient);
try {
startIntentSenderForResult(
intentSender, REQUEST_CODE_CREATOR, null, 0, 0, 0);
} catch (SendIntentException e) {
Log.i(TAG, "Failed to launch file chooser.");
}
}
});
}
#Override
protected void onResume() {
super.onResume();
if (mGoogleApiClient == null) {
// Create the API client and bind it to an instance variable.
// We use this instance as the callback for connection and connection
// failures.
// Since no account name is passed, the user is prompted to choose.
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(Drive.API)
.addScope(Drive.SCOPE_FILE)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
}
// Connect the client. Once connected, the camera is launched.
mGoogleApiClient.connect();
}
#Override

if (mGoogleApiClient != null) {
mGoogleApiClient.disconnect();
}
super.onPause();
}
#Override
protected void onActivityResult(final int requestCode, final int resultCode, final Intent data) {
switch (requestCode) {
case REQUEST_CODE_CAPTURE_IMAGE:
// Called after a photo has been taken.
if (resultCode == Activity.RESULT_OK) {
// Store the image data as a bitmap for writing later.
mBitmapToSave = (Bitmap) data.getExtras().get("data");
}
break;
case REQUEST_CODE_CREATOR:
// Called after a file is saved to Drive.
if (resultCode == RESULT_OK) {
Log.i(TAG, "Image successfully saved.");
mBitmapToSave = null;
// Just start the camera again for another photo.
startActivityForResult(new Intent(MediaStore.ACTION_IMAGE_CAPTURE),
REQUEST_CODE_CAPTURE_IMAGE);
}
break;
}
}
#Override
public void onConnectionFailed(ConnectionResult result) {
// Called whenever the API client fails to connect.
Log.i(TAG, "GoogleApiClient connection failed: " + result.toString());
if (!result.hasResolution()) {
// show the localized error dialog.
GooglePlayServicesUtil.getErrorDialog(result.getErrorCode(), this, 0).show();
return;
}
// The failure has a resolution. Resolve it.
// Called typically when the app is not yet authorized, and an
// authorization
// dialog is displayed to the user.
try {
result.startResolutionForResult(this, REQUEST_CODE_RESOLUTION);
} catch (SendIntentException e) {
Log.e(TAG, "Exception while starting resolution activity", e);
}
}
#Override
public void onConnected(Bundle connectionHint) {
Log.i(TAG, "API client connected.");
if (mBitmapToSave == null) {
// This activity has no UI of its own. Just start the camera.
startActivityForResult(new Intent(MediaStore.ACTION_IMAGE_CAPTURE),
REQUEST_CODE_CAPTURE_IMAGE);
return;
}
saveFileToDrive();
}
#Override
public void onConnectionSuspended(int cause) {
Log.i(TAG, "GoogleApiClient connection suspended");
}
}

This happens because after the first login/authorization android keeps using the same default account parameters. If you want to avoid the loop and make sure the picker shows again you must clear completely the default account by calling Plus.AccountApi.clearDefaultAccount(mGoogleApiClient) before reconnecting again.
To achieve this, you must add the Plus.API scope to the GoogleApiClient builder:
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(Drive.API)
.addApi(Plus.API)
.addScope(Drive.SCOPE_FILE)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
And then you can clear the default account before rebuilding the api client and connecting to a different account (rebuilding the api client when changing accounts avoids problems):
// if the api client existed, we terminate it
if (mGoogleApiClient != null && mGoogleApiClient.isConnected()) {
Plus.AccountApi.clearDefaultAccount(mGoogleApiClient);
mGoogleApiClient.disconnect();
}
// build new api client to avoid problems reusing it
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(Drive.API)
.addApi(Plus.API)
.addScope(Drive.SCOPE_FILE)
.setAccountName(account)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
mGoogleApiClient.connect();
No additional permissions or api activations are needed for using the Plus.API scope this way. I hope this helps with your problem.

It is a tough one, since I don't have time to completely re-run and analyze your code. And without running it, I don't see anything obvious.
But, since I have this stuff up and running in my app, I'd like to help. Unfortunately the Google Play services connection and authorization code is scattered all over my app's fragments and activities. So, I made an attempt to create a dummy activity and pull all the stuff in it. By 'all the stuff' I mean the account manager wrapper (GA) and associated account picker code.
The result is some 300 lines of gibberish that may work, but I don't make any claims it will. Take a look and good luck.

UPDATE (2015-Apr-11):
I've recently re-visited the code that handles Google Drive Authorization and Account switching. The result can be found here and it supports both REST and GDAA apis.

How to share the status for FB in Android programatically

I want to share the text/image programatically from my app on facebook.How should I proceed for that.After lots of googling I found lots of sample apps but as the latest FB SDK is deprecated those APIs it is hard to find the way using new SDK.Please help me out for this issue.
private void publishFeedDialog() {
Bundle params = new Bundle();

This is what i get for fb API 3.5 doc & which I have tried but it is crashing the app by saying session is null.

Here your session is null because you have not started it yet.
You have to start your session after login.
You can achieve this by using
Session.openActiveSession(this, true, new Session.StatusCallback() {
// callback when session changes state
});
For more information try going through the tutorials from http://developers.facebook.com/docs/android/scrumptious/authenticate/. These are really helpful.
Here is how I implemented --
This class is used to do initial stuffs to facebook
LoginFacebookClass
/**
* for integrating facebook in your app..
* Firstly import FacebookSDK lib project and add in your project as lib project.
* then
* create an instance of this class
* and, then call the facebook login method by passing reference of your activity and true, if you want to fetch data and, false if you want to share data on faceboko
* Please do whatever you want in the interface callback methods
* implemented by this class
*
*
* Note: Please write a line exactly in your activity's on activity result as
* -- Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
* here, 'Session' is Class of Facebook.
* 'this' is reference of your activity

Improve this question
all the code i saw until now not working with sdk 3.0.1
like this code :
Is uploading videos from an SD Card to Facebook possible with the Facebook SDK?
i think this because facebook change util file, but i not sure.
i will glud if someone will share with us (many developer that search for this code) working code (on sdk 3.0.1) that upload successfully mp4 file video to facebook wall from sd cards.
thanks ahead

Try this code, it is working:
File file=new File(Environment.getExternalStorageDirectory()+"/testvideo.mp4");
try {
Request audioRequest = Request.newUploadVideoRequest(session, file, new Request.Callback() {
#Override
public void onCompleted(Response response) {
// TODO Auto-generated method stub
if(response.getError()==null)
{
Toast.makeText(MainActivity.this, "Video Shared Successfully", Toast.LENGTH_SHORT).show();
}
else
{
Toast.makeText(MainActivity.this, response.getError().getErrorMessage(), Toast.LENGTH_SHORT).show();
}
}
});
audioRequest.executeAsync();
} catch (Exception e) {
e.printStackTrace();
}

This is a working to upload video on facebook with sdk 3.0.1
Enjoy...:)
