I am using the following code for adding a new ParseUser:
ParseUser user = new ParseUser();
user.setUsername("Rob");
user.setEmail("rob1989#gmail.com");
user.setPassword("robPass");
user.put("phone", "898989898");
user.saveInBackground();
After running this code nothing is reflected in my parse dashboard. I am not even getting any exception in the Android Studio.
However, when I run the following code, everything works just fine:
ParseObject item = new ParseObject("Item");
item.put("quantity", "dwad");
item.put("description", "dawda");
item.put("name", "fwafa");
item.saveInBackground();
Does anyone know what I am doing wrong here in ParseUser? Is there anyway to check the dashboard from Parse?
As clearly stated in the official guide, for ParseUsers you should use ParseUser.signUpInBackground():
user.signUpInBackground(new SignUpCallback() {
public void done(ParseException e) {
if (e == null) {
// Hooray! Let them use the app now.
} else {
// Sign up didn't succeed. Look at the ParseException
// to figure out what went wrong
}
}
});
Once the user has signed up for the first time, you can use save() and saveInBackground() for any subsequent change in the user attributes. But first you have got to sign him up.

I am a newbie (6 months going or so) and creating an app on Android (Java) that utilizes FireBase Auth with Google Sign In. (with only a few days of NodeJS exposure now) In other words my end user signs in with the Google Account. That part (I think) works pretty well so far. I use the Firestore Database heavily for a lot of things in the app.
So now I've gotten to the point where I want to use (Callable) Cloud Functions with HTTP Triggers. (never having done any of this before) I'm trying to get a proof of concept working at this time. The actual function works and I can trigger it from my app.
It appears that I cannot figure out how to make the function "private" though; as in "adding proper Members" to the Cloud function who have the right to invoke the function.
I have tried a few different things by trial error, but first let me show what I have.
This is the Cloud Function and I'm passing in an arbitrary String as a test, works nicely: (as long as "allUsers" have the role/right to invoke the function; in other words when the function is public.
exports.createTest = functions.https.onCall((data, context) => {
const text = data.text;
const uid = context.auth.uid;
const name = context.auth.token.name || null;
const email = context.auth.token.email || null;
console.log('UID: ', uid);
console.log('Name: ', name);
console.log('Email: ', email);
console.log('Message: ', text);
});
The above function gets triggered in my Android/Java code like this: (I think this code came from Google Doc/Sample/Example
private FirebaseFunctions mFunctions;
...
private void testing() {
mFunctions = FirebaseFunctions.getInstance();
Log.e(LOG_TAG, "Testing executed!");
String testMessage = "Hello Hello Testing 123 Mic Check";
createTest(testMessage)
.addOnCompleteListener(new OnCompleteListener<String>() {
#Override
public void onComplete(#NonNull Task<String> task) {
if (!task.isSuccessful()) {
Exception e = task.getException();
if (e instanceof FirebaseFunctionsException) {
FirebaseFunctionsException ffe = (FirebaseFunctionsException) e;
FirebaseFunctionsException.Code code = ffe.getCode();
Object details = ffe.getDetails();
Log.e(LOG_TAG, "FFE: " + ffe.getMessage() );
Log.e(LOG_TAG, "Code: " + code);
Log.e(LOG_TAG, "Details:" + details);
}
// ...
}
// ...
}
});
}
private Task<String> createTest(String text) {
// Create the arguments to the callable function.
Map<String, Object> data = new HashMap<>();
data.put("text", text);
data.put("push", true);
return mFunctions
.getHttpsCallable("createTest") //this is the function name
.call(data)
.continueWith(new Continuation<HttpsCallableResult, String>() {
#Override
public String then(#NonNull Task<HttpsCallableResult> task) throws Exception {
// This continuation runs on either success or failure, but if the task
// has failed then getResult() will throw an Exception which will be
// propagated down.
String result = (String) task.getResult().getData();
if (result != null) {
Log.e(LOG_TAG, "Result: " + result);
}
return result;
}
});
}
Only when I have "allUsers" added with the role/right to "invoke Cloud Function" then I get this working. My understanding of HTTP Requests and such is pretty limited, which is not making things easier.
I tried using the "allAuthenticatedUsers" options, which I figured would do the trick, because I actually authenticate my Users in the app through Firebase/Google Sign In. This Cloud Function shall only be available to either a) authenticated users or b) users of a specific domain. (I have a domain, let's say #testorganization.com) Or if I can identify my particular app (api key?) then that would work, too.
The moment I add a member "allAuthenticatedUsers" with role to invoke the function (and remove "allUsers) nothing happens. I also tried adding the entire domain, but that wouldn't work. (duh) Also tried adding my service account (trial and error at this point) and didn't seem to work.
In my Node JS code I am actually receiving the UID of the authenticated user, so it appears that some kind of user authentication information is already being exchanged.
With that knowledge, I can (successfully tried this) get the UID and cross check that against my database and verify a user that way, but seems unnecessary and I should be able to make the permissions work. (lock the function down entirely) Plus this took a really long time just finish this cross check. Or is this pretty standard procedure to do?
Like this-->
const usersRef = admin.firestore().collection('users').doc(uid)
usersRef.get()
.then((docSnapshot) => {
if (docSnapshot.exists) {
usersRef.onSnapshot((doc) => {
console.log('User Type logged in: ', doc.data().userCategory)
console.log('User Title: ', doc.data().userTitle)
});
} else {
console.log('User does not exist')
}
});
Edit:
So while not having figured out how to shut down the function entirely, I did discover that instead of cross checking my users, I can simple check for auth like this:
if (context.auth){
//user is auth'd
} else {
//no auth
}
That's a little bit better, I guess. (but still doesn't technically prevent access to the function?!)
Thank you so much for any help. Much appreciated.
Edit2:
Here is a screensshot of the area in the cloud console (for cloud function roles/privileges) that I am referring to:
https://imgur.com/cBsjaaL
With a Callable Cloud Function, if you want to ensure that only authenticated users can trigger it's business logic, you actually don't need to configure any extra "cloud function roles/privileges" as shown at the bottom of your question.
By default, with a Callable Cloud Function you will get, when available, "Firebase Authentication and FCM tokens automatically included in requests" and it will "automatically deserializes the request body and validates auth tokens", as explained in the doc.
So you just have to follow the doc and use the context parameter. As you have mentioned in your question, you can check the user is authenticated by doing:
if (context.auth) {
//...
}
If you want to verify the user email, you would do:
exports.addMessage = functions.https.onCall((data, context) => {
const uid = context.auth.uid;
return admin.auth().getUser(uid)
.then(userRecord => {
const userEmail = userRecord.email;
//....
})
.catch(function(error) {
console.log('Error fetching user data:', error);
// Send back an error to the front end
// See https://firebase.google.com/docs/functions/callable#handle_errors
});
});
You will find more examples on how to "work with" users with the Admin SDK here in the doc.
I'm trying to use QuickBlox in my android application, I read the guide and imported the sample and everything worked fine.
I changed a few things that user can login using EditText for username and another for password.. and it worked fine.
But now I want to add a Register Button that makes the user able to register new account.. I don't know how to do that.. Any Idea?
Here's the solution :
QBUsers.signUp(user, new QBEntityCallbackImpl<QBUser>() {
public void onSuccess(QBUser result, Bundle params) {
// success
}
public void onError(List<String> errors) {
AlertDialog.Builder dialog = new AlertDialog.Builder(
SplashActivity.this);
dialog.setMessage(
"register errors: " + errors)
.create().show();
}
});
I've got a really odd problem with the Google Drive Android SDK. I've been using it for several months now, and until last week it performed perfectly. However, there is now a really odd error, which doesn't occur all the time but does 9 out of 10 times.
I'm trying to list the user's files and folders stored in a particular Google Drive folder. When I'm trying to use the method Drive.files().list().execute(), 9 out of 10 times literally nothing happens. The method just hangs, and even if I leave it for an hour, it just remains doing... nothing.
The code I'm using is below - all of this being run within the doInBackground of an AsyncTask. I've checked credentials - they are all fine, as is the app's certificate's SHA1 hash. No exceptions are thrown. Google searches have yielded nothing. Here is the particular bit of code that's bothering me:
try {
GoogleAccountCredential credential = GoogleAccountCredential.usingOAuth2(
SettingsActivity.this, Arrays.asList(DriveScopes.DRIVE));
if (googleAccountName != null && googleAccountName.length() > 0) {
credential.setSelectedAccountName(googleAccountName);
Drive service = new Drive.Builder(AndroidHttp.newCompatibleTransport(),
new GsonFactory(), credential).build();
service.files().list().execute(); // Google Drive fails here
} else {
// ...
}
} catch (final UserRecoverableAuthIOException e) {
// Authorisation Needed
runOnUiThread(new Runnable() {
#Override
public void run() {
try {
startActivityForResult(e.getIntent(), REQUEST_AUTHORISE_GDRIVE);
} catch (Exception e) {
Log.e("SettingsActivity: Google Drive", "Unable to add Google Drive account due to Exception after trying to show the Google Drive authroise request intent, as the UserRecoverableIOException was originally thrown. Error message:\n" + e.getMessage());
}
}
});
Log.d("SettingsActivity: Google Drive", "UserRecoverableAuthIOException when trying to add Google Drive account. This is normal if this is the first time the user has tried to use Google Drive. Error message:\n" + e.getMessage());
return;
} catch (Exception e) {
Log.e("SettingsActivity: Google Drive", "Unable to add Google Drive account. Error message:\n" + e.getMessage());
return;
}
I'm using Drive API v2. Thanks everyone!
Edit
Having played around a bit more, it turns out this isn't for just listing files. Trying to interact with any file on Google Drive behaves the same way - deleting, downloading, creating... Anything! I have also noticed that putting the device in aeroplane mode so it has not internet access makes no difference either: Google Drive doesn't throw an exception, or even return, it just freezes the thread it's on.
I've updated to the very latest Drive API lib but that hasn't helped. I remembered that the error happened soon after I added the JSch SSH library to the project, so I removed that, but it made no difference. Removing and re-adding the Drive API v2 has made no difference either, and nor has cleaning the project.
Edit 2
I've found something which may be significant. On the Google Developer console, I had some Drive errors recorded as follows:
TOP ERRORS:
Requests % Requests Methods Error codes
18 38.30% drive.files.list 400
14 29.79% drive.files.insert 500
11 23.40% drive.files.update 500
4 8.51% drive.files.get 400
Do you reckon these are the errors? How could I fix them? Thanks
This is my code and it's work
new AsyncTask<Void, Void, List<File>>() {
#Override
protected List<File> doInBackground(Void... params) {
List<File> result = new ArrayList<File>();
try {
com.google.api.services.drive.Drive.Files.List list = service.files().list();
list.setQ("'" + sourcePath + "' in parents");
FileList fileList = list.execute();
result = fileList.getItems();
if(result != null) {
return result;
}
} catch (UserRecoverableAuthIOException e) {
startActivityForResult(e.getIntent(), REQUEST_AUTHORIZATION);
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
protected void onPostExecute(List<File> result) {
//This is List file from Google Drive
};
}.execute();
I've come up with a solution which does work, and thought I'd post it so others could see it if they happen to come across the problem.
Luckily, I had backed up all of the previous versions of the app. So I restored the whole project to how it was two weeks ago, copied and pasted all changes from the newer version which had been made since then, and it worked. I don't see why this should work, since the end result is the same project, but it does!
Google Drive List Files
This might help you.. Try to display it in ListView u will see all fetched folders
public void if_db_updated(Drive service)
{
try {
Files.List request = service.files().list().setQ("mimeType = 'application/vnd.google-apps.folder'");
FileList files = request.execute();
for(File file : files.getItems())
{
String title = file.getTitle();
showToast(title);
}
} catch (UserRecoverableAuthIOException e) {
startActivityForResult(e.getIntent(), REQUEST_AUTHORIZATION);
} catch (IOException e) {
e.printStackTrace();
}
}
public void showToast(final String toast) {
runOnUiThread(new Runnable() {
#Override
public void run() {
Toast.makeText(getApplicationContext(), toast, Toast.LENGTH_SHORT).show();
}
});
I am attempting to integrate the Dropbox chooser drop-in api into my application. I am running into an abnormal issue. In my app when I launch the dbx chooser, anytime that I select a file the application fails with the following error code:
Sorry, an error has occurred. Please try again later.
Here is the portion of my code that implements the Dropbox API. This portion of the code is where the dropbox api is initially invoked.
public void StartDropboxApplication() {
// create the chooser
DbxChooser chooser = new DbxChooser(APP_KEY);
DbxChooser.ResultType result;
// determine which mode to be in // TODO REMOVE ALL BUT FILE CONTENT TODO SIMPLIFY by making this a setting
switch(( (RadioGroup) ParentActivity.findViewById(R.id.link_type)).getCheckedRadioButtonId() ) {
case R.id.link_type_content:
result = DbxChooser.ResultType.DIRECT_LINK;
break;
default:
throw new RuntimeException("Radio Group Related error.");
}
// launch the new activity
chooser.forResultType(result).launch(ParentActivity, 0);
}
Here is the position where the code should then pick it up although it never does.
protected void onActivityResult( int request, int result, Intent data ) {
Log.i(fileName, "result: " + result);
// check to see if the camera took a picture
if (request == 1) {
// check to see if the picture was successfully taken
if (result == Activity.RESULT_OK) {
onPicture();
} else {
Log.i(fileName, "Camera App cancelled.");
}
} else if (request == 0) {
if ( result == Activity.RESULT_OK ) {
onDropbox(data);
} else {
Log.i(fileName, "dropbox related issue.");
}
}
}
Thank you for any help or suggestions that you are able to provide.
I was able to solve my own issues and get this working. On the off chance that someone else has a similar problem I will detail the solution. The first issue was I was that my APP_KEY was incorrect.
The next issue was that I was attempting to read from a direct link instead of a content link. The direct link provides the application with a link to the file on the Dropbox server whereas the content link provides the application with a cached version of the file. If the file is not present on the device, the SDK downloads a copy for you.
I want to post a predefind message with link on facebook wall without user intervention .I mean user just log into facebook and my predefind message should be post with link on user's facebook wall.
Below is my code.
public class PostOnFacebookWall {
public static void postOnWall(Facebook facebook , final Context context, final String placeName) {
Bundle params = new Bundle();
params.putString("message", placeName);
facebook.dialog(context, "feed", params ,new DialogListener() {
public void onFacebookError(FacebookError e) {
}
public void onError(DialogError e) {
}
public void onComplete(Bundle values) {
Toast.makeText(context, placeName+" for today's hangout has been posted on your facebook wall. ", Toast.LENGTH_LONG).show();
}
public void onCancel() {
}
});
}
}
I've looked so many links about my question like below
http://stackoverflow.com/questions/11316683/adding-content-to-facebook-feed-dialog-with-new-facebook-sdk-for-android
which passed all the parameter like "link","description","image" and much more.
Someone is saying that u have to pass all the parameters.I just want to predefind messages and link over that.
My message is should be "Let's hangout at " and here placeName should be a link.
And this complete msg i want to pass from my code .I don't want that my code opens dialog where user enters it's message.
If you need to post a predefined message to a User's Facebook Wall, you shouldn't be using the facebook.dialog method.
For more on why that shouldn't be used, read my answer posted here: https://stackoverflow.com/a/13507030/450534
That being said, to get the result you want, try this piece of code:
Bundle postStatusMessage = new Bundle();
// ADD THE STATUS MESSAGE TO THE BUNDLE
postStatusMessage.putString("message", "Let's hangout at " + placeName);
postStatusMessage.putString("link", "www.the_example_web_address.com");
Utility.mAsyncRunner.request("me/feed", postStatusMessage, "POST", new StatusUpdateListener(), null);
And this is where you can check the response from the Facebook API by parsing the String response:
private class StatusUpdateListener extends BaseRequestListener {
#Override
public void onComplete(String response, Object state) {
}
A point to note here is, you cannot pass a message with a link in it. To elaborate (as the earlier statement might sound confusing), You cannot pass a link in the message tag with a link that will be parsed by Facebook and show up in a post like links on FB do.
To see the difference clearly, post the status update using the code above and see how it looks on Facebook. Then, after having done that, remove this postStatusMessage.putString("link", "www.the_example_web_address.com"); from the code above and include the link in the message tag, post it and see how it looks on Facebook.
