i'm new to android studio, and i dont know much about it. My question here is do android provide any authentication method like aspx / php (laravel) that check if a user stay logged in and etc.
From what i learnt so far, i have to sign in to my app by receiving json/xml data from my web service, so my app just display the next screen after the id/password is correct? Is there any more security issue that i need to worried about? Aspx authentication do authenticate on every page even after your first login. But after some research i dont see android studio have this kind of authentication. Am i missing something?
You can use Firebase Authentication for sign-in methods and user management.
You can add Firebase to Android Studio in Tools > Firebase.
No there is no default function in android that does what you want, you have to add a new sdk to handle this issue. You Can Use Firebase as Aviad Nemet said. Or you save in the shared preferences that you user is authenticated after login success. Saving in the Shared Preferences is safe.

Please give me solution or tell me the reason why it is happening if anyone know.
Thanks in advance.
Add "account_type" tag in your strings.xml
It will avoid conflict of two sales force sdk in single device.
You should check if the session ID is active for Salesforce.
SalesForce OAuth2 Ongoing Authorization flow documentation says
The customer opens a mobile app.
If the session ID is active, the app starts immediately. If the session ID is stale, the app uses the refresh token from its initial authorization to get an updated session ID.
The app starts.
Please read the Salesforce OAuth2 Authentication Flow for details.
I am attempting to integrate onboarding screens into my Android application that allows users to register through Email/Password, or through Logging in with Facebook.
Is there any way of programmatically knowing when the user logs in through Facebook whether it is the first time of doing so?
I only want the Onboarding Activity to launch the first time the user logs in through Facebook (after accepting the permissions request), not every time they log in.
Any help with this issue would be hugely appreciated.
use facebook API's to authenticate the users.Login to the facebook developer console to register your application and get the key hashes that will uniquely define your application.
Use facebook Api by this link https://developers.facebook.com/ register your app.
and follow the instruction as mentioned.Then you can integrate facebook logging in your App
I'm working at my first app and I want to login to a php website, but want to use the Login Activity of Android Studio. My design looks perfect but I don't know how I can access my Database. So how can I compare the email entered from the user and the email saved in the databse?...same for the password.
Thanks a lot for helping me
Your app doesn't know your webpage's database. You need to do add some backend API to your website (via REST, SOAP, HTTP or whatever) so that the app can query for users with given name/password and make that api call from the app. I strongly recommend using encryption.
I am trying to make an application which logs into facebook by asking for the email and the password of the user, without taking him to the WebView pop-up. Is there any way to do this? I have been trying to do some HTTP manipulation but i couldn't succeed!
Thank you!
Android Dont provide native support of facebook and twitter integration so i think you must pop up atleast one time for login facebook then you save user email to your local db and then use it :)
If you use the latest Facebook SDK for android, v3.6.0, https://github.com/facebook/facebook-android-sdk, the default behavior is:
If the user doesn't have the Facebook app installed, then the user will see the web view popup and has to type username and password manually.
If the user has the Facebook app installed, but hasn't approved the permissions, then your app will switch to Facebook app where the user can approve the permissions and come back to your app.
If the user has the Facebook app installed and already approved the permissions, and the user will see a native android dialog.
At any time, if you change permission requirements, then since the user needs to approve the additional permissions, in that case your app will also switch to the Facebook app.
If you don't want to provide native support, you have to handle all of these and has to frequently update your code, because Facebook updates its SDK and deprecates old methods quite often. The best practice is simply sticking to the Facebook SDK, unless you have any other requirements.
I am currently developing an android game using facebook invites (such as ruzzle or draw sthg). I have successfully passed the login part and the request part. However, whenever I make a request to a friend to invite him to play with me and they receive the request on the facebook app for android when they click on the request, the phone opens up the google play store. I do not understand why because the app is already installed on the phone and so it should open up the app directly right?
I used the exact same code as shown in the facebook developers site and I configured my app on their developers site too.
Thank you in advance for your help.
