Now
I am going to share about the Facebook Integration without using
external Facebook SDK Library.Its a better way to use to Facebook in our
project.Because some time Facebook SDK Library methods files can able to
deprecate in future, So this way is best to integrate Facebook in
android.
Also get facebook profile picture,user name,first name,last name,email and fb id.
Also get facebook profile picture,user name,first name,last name,email and fb id.
Using this code
1. Generating Key Hash for Facebook
Open
your command prompt (CMD) and run the following command to generate
your keyhash. While generating hashkey it should ask you password.
Give password as android.
If it don’t ask for password your keystore path is incorrect.
keytool
-exportcert -alias androiddebugkey -keystore
"C:\Users\User\.android\debug.keystore" | openssl sha1
-binary | openssl base64
-
You will get your hash key for debug.keystore.
Example- XQQl+LMlyirxGOVWiJ34L1XRqPg=
2. Registering your Facebook application
i).Open Facebook developer site
ii).App-Add a New App-Choose Android icon-Type App Name-Application category.
iii).Enter Android application package name and Activity name.
iii).Then Enter Key Hash value.
iv).Click Create App,Finally get APP ID.
3.Add Facebook SDK codes in our package
i).Add fb.android package in your project then only able to access facebook.
activity_main.xml
MainActivity.java
