Facebook For Java Aplication



If you have a Java-enabled phone you can head to m.facebook.com and download the app right away. You can also get it at some of the popular independent app stores, including GetJar, Appia, and Mobile Weaver.

The first step is to create the (CalendarModule.java or CalendarModule.kt) Java/Kotlin file inside android/app/src/main/java/com/your-app-name/ folder (the folder is the same for both for either Kotlin or Java). This Java/Kotlin file will contain your native module Java/Kotlin class.


To add your Native Module to ReactPackage, first create a new Java/Kotlin Class named (MyAppPackage.java or MyAppPackage.kt) that implements ReactPackage inside the android/app/src/main/java/com/your-app-name/ folder:


To register the CalendarModule package, you must add MyAppPackage to the list of packages returned in ReactNativeHost's getPackages() method. Open up your MainApplication.java or MainApplication.kt file, which can be found in the following path: android/app/src/main/java/com/your-app-name/.


For more detail, you can find the Promise.java interface here. If userInfo is not provided, ReactNative will set it to null. For the rest of the parameters React Native will use a default value. The message argument provides the error message shown at the top of an error call stack. Below is an example of the error message shown in JavaScript from the following reject call in Java/Kotlin.


So, in order to allow facebook-posting application, you need to have one of the following apps need to be allowed in the same rule to allow facebook-posting through at that security rule depending on what is to be allowed:


We can use the object model API to get names and their public posts about the term java. In the Listing 3, lines 1 through 3 lines create JsonReader; line 5 creates JsonObject for the results; line 7 loops over each result; and lines 8 through 11 get the name of the person who posted, get the public post, and prints them. Note that the JsonReader and other objects in this API can be used in the try-with-resources statement (which is also called automatic resource management [ARM]).


Let's use the streaming API to do the same thing that was done with the object model API, that is, to search Facebook's public posts about java. In Listing 4, lines 1 through 3 create a streaming parser, lines 4 through 5 get the next event, line 6 looks for the KEY_NAME event, lines 8 through 11 read names and print them, and lines 14 through 16 read the public posts and print them. The use of streaming API provides an efficient way to access names and their public posts when compared to the same task using the object model API.


As mentioned above, the ConnectController is the main workforce in this area. This controller will handle our GET requests when we want to connect to Facebook. It requires just two simple views to work properly - connect/facebookConnect and connect/facebookConnected.


connectionRepository.findPrimaryConnection(Facebook.class) will only be null if the user didn't authorize our application to retrieve data from Facebook. If this is the case, the application simply returns to /connect/facebook.


Buck currently requires Java 8; we are working toward support for future versions. If you have multiple installations of Java on your development computer, you might get warnings from Buck that you are using an unsupported version of Java. To resolve this issue, set the JAVA_HOME environment variable to the directory for version 8 of the Java Development Kit (JDK). Note that the directory that JAVA_HOME points to should contain a bin subdirectory which in turn contains binaries for the Java compiler (javac) and Java runtime (java).

We are going to be building a Java application that prints out "Hello Buck". The code to build the application consists of both a library and app component. To build this Java application, the code you cloned has all the files necessary. From the hello-buck-java directory, you will find:


com/facebook/buck/demo/BUCK: This build file is what makes Buck work and is the trigger for building the application. It defines all the build rules for your source code. The key rules you will see in this file is java_binary and java_library. A build rule may also include dependencies (generally via deps), which may be from other build files.


In order to build the library, you use the buck build command, specifying your app as the target. The target may be defined in the [alias] section in the .buckconfig file or it would be the name of your Java application prepended by //[the directory where your project is located]: (e.g., //com/facebook/buck/demo:hello-buck-java).


OAuthClient can use different java http clients with customized configurations like timeouts, connection pools, etc. in order communicate with authorization servers and receive access tokens. Oltu provides an exemplar implementation of the URLConnection client and Apache's HttpClient 4.


OAuthClientRequest request = OAuthClientRequest .tokenLocation(" _token") .setGrantType(GrantType.AUTHORIZATION_CODE) .setClientId("your-facebook-application-client-id") .setClientSecret("your-facebook-application-client-secret") .setRedirectURI(" ") .setCode(code) .buildBodyMessage();


Are you still unsure as to why you should study Java? Perhaps the hefty salaries of Java developers should settle the case for you. According to well-documented studies, employment for software developers would increase by 22% over the next decade, with backend developers in particularly high demand. In addition, the average base salary for a backend developer in the United States is $115,002. Considering these figures, java developers have excellent prospects of drawing higher salaries.


If you are developing an application that must be compatible with previous versions of Java, you can set the version of the source code that the compiler should expect, and the target runtime version for which you want to compile. To set the source and target version, select it in the Source/Binary Format drop-down list under the list of source package folders. This setting defines the -source and -target options of the javac Java compiler.


If development occurs in multiple countries, encoding of source files in projects may vary. You need to make sure that the Java compiler knows the encoding. To set the encoding of source files in a project, select it in the Encoding drop-down list under the list of source package folders. This setting defines the -encoding option of the javac Java compiler.
