Loglr
So happy to inform this library has been ported to Kotlin!
The easiest way to get your user logged in via Tumblr
Loglr is library that enables developers to implement 'Login via Tumblr' with as minimum frustration as possible.
Note : The library is in active development. On and off, one may encounter bugs or mistakes. Please report them on the issue tracker.
Download the demo application from the PlayStore!
Importing to your project
Gradle :
implementation 'com.daksh:loglr:2.1.3' Usage
Loglr uses singleton pattern and accepts a minimum of 5 parameters to complete the login process. Each method that accepts a parameter returns the Loglr Instance to avoid boiler plate code. Retrieve the Loglr instance and set up the Consumer Key and Consumer Secret Key received from Tumblr apps dashboard. You get these when you set up a new app.
Loglr.
//Set your application consumer key from Tumblr
.setConsumerKey("ENTER CONSUMER KEY HERE")
//Set your application Secret consumer key from Tumblr
.setConsumerSecretKey("ENTER CONSUMER SECRET KEY") Up next, you need to pass an interface that will be called when Login succeeds.
//Implement interface to receive Token and Secret Token
.setLoginListener(loginListener) In case login fails and exceptions are thrown, an exception handler interface needs to be passed so you may ascertain reasons for failure.
//Interface to receive call backs when things go wrong
.setExceptionHandler(exceptionHandler) Amongst the most important parameters, is the URL callback method. Post login, Tumblr redirects the authenticating user to the callback URL set up on Tumblr Apps dashboard. When the URL is received by Loglr, further login procedure is carried out. If no URL is provided, the login shall fail.
//The URL callback needs to be same as the one entered on the Tumblr Apps Dashboard
.setUrlCallBack(strUrlCallback) Optionally, if you prefer having your own loading dialogs replaced with default ones, you may do so by passing the class that extends Dialog. This gives you an opportunity to present your users with a consistent experience with the rest of the app elements. Please note, an object of the custom dialog is manufactured by Loglr by calling the default constructor. Please ensure the class does not require any other parameters to be passed. To view an example, please refer MainActivity and LoadingDialog classes under app folder.
//Pass the Loading Dialog class
.setLoadingDialog(LoadingDialog.class) Loglr supports auto detecting the OTP message received by users with 2 Factor-Authentication enabled. A dialog informing the user is displayed before the permission is requested. If you wish to disable this feature, you may do so by calling the following method and passing false. Note : by default, this feature is enabled.
//Pass a boolean variable that informs loglr if OTP auto detection is to be enabled or not
.enable2FA(true) To customize the action bar background color and address bar color, you may use :
//Pass the color resource ID
.setActionbarColor(R.color.activity_color_actionbar)
.setTextColor(R.color.activity_color_text) Finally, start the login procedure.
//Initiate login in an activity of it's own
.initiate(context);
When login succeeds, a call back is executed to the LoginListener that was passed with .setLoginListener(loginListener) method. An object of LoginResult is passed which contains Token and Secret Token which may be used in conjunction with Jumlr Library to retrieve user information or make requests on user's behalf.
String strOAuthToken = loginResult.getOAuthToken();
String strOAuthTokenSecret = loginResult.getOAuthTokenSecret();
To use received tokens with Jumblr :
// Create a new client
JumblrClient client = new JumblrClient("ENTER CONSUMER KEY HERE", "ENTER CONSUMER SECRET KEY");
client.setToken(strOAuthToken, strOAuthTokenSecret);
With Jumblr client set, API requests may be made. For more information on basic usage, refer Tumblr's Jumblr's official guide.
Foot notes
Permissions listed in manifest :
READ_SMS&RECEIVE_SMS: They are used to auto-populate OTP (2 Factor-Authentication) if the user has them enabled on Tumblr.WAKE_LOCK&ACCESS_NETWORK_STATE: Firebase analytics uses these permissions to ensure events are logged properly.
If you wish to remove any permission from your app, add the following line in each of the permissions you wish to remove : tools:node="remove"
