Facebook integration for Android

I am developing an Android application where I want to integrate facebook. I went through the link http://developers.facebook.com/docs/guides/mobile/#android

I have little doubt:

  • I generated the key using keytool, but could not figure out how to register it in the Mobile and Devices section. Where is this Mobile Devices section located?

  • How can I implement facebook functionality as buttons in an application? Any sample code will be really helpful.

1) Follow the following path:

  • Go to http://www.facebook.com/developers/
  • Click on the application link on the right.
  • click change settings (in the menu on the right)
  • Click "Mobile" and devices in the menu on the left.

2) Do you want to create your own application or access it through web browsing? If this is a web view, then create a web page, as in any other html code. To get started with your native application, have you looked at an example: https://github.com/facebook/facebook-android-sdk/tree/master/examples/simple ?

I really do not answer the question, but I recommend using general intentions in Android instead of the popup API, which requires authentication. If an Android user has a Facebook account, he will likely have a facebook application.

UPDATED: Take a look at the documentation: http://developer.android.com/reference/android/content/Intent.html

It should be something like this:

Intent intent = new Intent(Intent.ACTION_SEND); intent.setType("text/plain"); intent.putExtra(Intent.EXTRA_TEXT, "Extra message"); startActivity(Intent.createChooser(intent, "message"));

Perhaps you can directly target only the facebook app.

I used facebook sdk 4.10.0 to integrate login into my android app. Next tutorial:

Facebook integration of Android studio.

You can get first name, last name, email address, gender, facebook id and date of birth from facebbok.

The above guide also explains how to create an application in the facebook developer console via video.

Gradle.build

apply plugin: 'com.android.application'

}
