I have to implement a function to upload a file to Google Drive.
As in Quick Start guide.
At first, I call generateLinkAuth to generate the link to get the code.
Then generateCode will be executed to get the token.
Everything is fine.
List<String> SCOPES = Arrays.asList("https://www.googleapis.com/auth/drive.file", "https://www.googleapis.com/auth/userinfo.email",
"https://www.googleapis.com/auth/userinfo.profile", DriveScopes.DRIVE);
public String generateLinkAuth() {
mHttpTransport = new NetHttpTransport();
mJsonFactory = new JacksonFactory();
mFlow = new GoogleAuthorizationCodeFlow.Builder(mHttpTransport, mJsonFactory, CLIENT_ID, CLIENT_SECRET, SCOPES).setAccessType("online").setApprovalPrompt("force").build();
String url = mFlow.newAuthorizationUrl().setRedirectUri(REDIRECT_URI).build();
System.out.println("url :" + url);
return url;
}
public void generateCode(String code) {
new GetCredentialFromCode(mContext, code).execute();
}
class GetCredentialFromCode extends AsyncTask<Void, Void, Void> {
private Context mContext;
private String code;
private final ProgressDialog mDialog;
public GetCredentialFromCode(Context context, String cd) {
mContext = context;
mDialog = new ProgressDialog(context);
mDialog.show();
mDialog.setTitle("Uploading ...");
code = cd;
}
@Override
protected Void doInBackground(Void... params) {
if (mFlow != null) {
try {
mResponse = mFlow.newTokenRequest(code).setRedirectUri(REDIRECT_URI).execute();
mCredential = new GoogleCredential();
mCredential.setFromTokenResponse(mResponse);
String accessToken = mCredential.getAccessToken();
Editor edit = mPrefs.edit();
edit.putString(GOOGLE_DRIVE_TOKEN, accessToken);
edit.commit();
String accessTokenSave = mPrefs.getString(GOOGLE_DRIVE_TOKEN, "NO KEY");
Log.e(TAG, "access Token Saved is " + accessTokenSave);
} catch (IOException e) {
Editor edit = mPrefs.edit();
edit.putString(GOOGLE_DRIVE_TOKEN, "NO KEY");
e.printStackTrace();
}
}
String accessTokenSave = mPrefs.getString(GOOGLE_DRIVE_TOKEN, "NO KEY");
mHttpTransport = new NetHttpTransport();
mJsonFactory = new JacksonFactory();
mCredential = new GoogleCredential().setAccessToken(accessTokenSave);
getUserInfo();
mDriveService = new Drive.Builder(mHttpTransport, mJsonFactory, mCredential).build();
return null;
}
@Override
protected void onPostExecute(Void result) {
mDialog.dismiss();
GoogleDriveLogInAct act= (GoogleDriveLogInAct) mContext;
act.goBackSettingScreen();
}
}
The problem is that the token will expire in 1 hour with setAccessType("online"), so I change it to setAccessType("offline").
When I change it and run my android app again, I get an error - when I execute the below code.
mResponse = mFlow.newTokenRequest(code).setRedirectUri(REDIRECT_URI).execute();
mCredential = new GoogleCredential();
mCredential.setFromTokenResponse(mResponse);
When I try to debug on console execute mCredential.setFromTokenResponse(mResponse). , an exception will be raised

How can I use accessType offline?
Is there anything I have to modify to use with this mode?

The OP wrote:
have solve this problem... I should declare
GoogleCredential
by usingGoogleCredential.Build()
instead ofnew GoogleCredential()
