Step 1 : Download Facebook SDK for Android
I hope you already download it, if not here is the link https://developers.facebook.com/docs/android (facebook-android-sdk-3.17.2.zip size 4.8mb) you can also the repo on Github
Step 2 : Prerequisites
1. Facebook SDK 3.17.2 for Android
2. Eclipse Juno v4.2 or later with a default install and the Android SDK
(Better to download Android ADT tool form Android Developer website).
3. Java v1.6 or above
4. Android API level 9 component installed in order to test your app on Emulator.
Step 3 : Installing Facebook.apk on Android Emulator
As earlier verions we do not get the facebook apk file included in the zip file, so if you want to test it on an Emulator then download Facebook-11.zip (https://developers.facebook.com/resources/Facebook-11.zip)
As we do not have Google Play installed on a Emulator we need to install the apk using the adb install command.
Steps :
a. Open Android Virtual Device (AVD) Manager (In Eclipse Menu under Window > Android Virtual Device Manager)
b. Create a new AVD with API level 8, if you already have a AVD, no need to create new
c. Launch the AVD, wait till the Emulator Loads Completely, i.e. the OS loads and Lock Screen appears (or else you may get some unwanted error while installing facebook.apk).
d. Locate Facebook-11.apk and note down the absolute path of the Apk
e. Now locate adb tools : eg. E:\Eclipse\adt-bundle-windows-x86_64-20130522\ adt-bundle-windows-x86_64-20130522\ sdk\ platform-tools
f. Now open Command Prompt (Terminal) and go to the location where adb tool is present and execute the following command
adb install I:\Facebook-11.apk
Note : It may take 15-20 minutes for facebook apk to be installed on the Emulator (patience needed).
Once this is done you will get a Success message on the Command prompt and you will see Facebook app icon on your AVD.
Step 4 : Setting up Workspace with Facebook SDK libraries
Important for Windows users ! : Your Facebook SDK files and Workspace should be on the same drive or else you may face issues while linking it. So before starting just make sure that they are under the same drive (for me its E:/)
Open Workspace,
Right Click > Import Existing Projects into Workspace,
Locate FacebookSDK Projects and Select Facebook SDK Projects only (deselect all others)
Create a new Android Project for testing, fill in the Application name,Project Name and Package Name, See that the Java Version is 1.6.
I have added an fb icon under bin > res > drawable-hdpi and have set it as a ImageView in MainActivity.
Step 5 : Generating KeyHash for your device
Many of us get stuck at generating KeyHashes!. The simplest and quickest way to generate keyhash is add the following code onCreate function.
try {
PackageInfo info = getPackageManager().getPackageInfo(
"com.code2care.facebookSDKTuts",
PackageManager.GET_SIGNATURES);
for (Signature signature : info.signatures) {
MessageDigest md = MessageDigest.getInstance("SHA");
md.update(signature.toByteArray());
System.out.println("KeyHash : "+ Base64.encodeToString(md.digest(), Base64.DEFAULT));
}
} catch (NameNotFoundException e) {
} catch (NoSuchAlgorithmException e) {
}
Note : Remember to change the package name accordingly (for me its com.code2care.facebookSDKTuts) Once you run the app you will find the keyhash in LogCat,
Step 6: Register your App with Facebook Developers Android App Page
You need to add this keyhash to your facebook developer accounts App details page.
a. Go to https://developers.facebook.com/apps, Click on Create New App
b. You will get a Pop-up, enter the App name (you can use your app name instead) and select a catagory.
c. Now the Dashboard will be loaded, and you will get the App ID and Secret Key for your App.
d. Now go to Settings and Click Add Platform, Select Android
e. Fill in the Details like Package Name (eg. com.code2care.demos.317Test) , Class Name (om.code2care.demos.317Test.MainActivity) and the KeyHash we just created at step 5.
f. Go to Status & Review and Make the App Live, (Note : Make sure you add your email id in Contact Email in Settings)
Step 7: Configuration of String XML of you App
Add applicationId to string.xml.
<string name="applicationId">318980594930439</string>
Add the below lines in your Manifest.xml file, in application tag just after your main acitivity tag,
<activity android:name="com.facebook.LoginActivity"
android:theme="@android:style/Theme.Translucent.NoTitleBar"
android:label="@string/app_name" />
<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/applicationId"/>
also add this line, change your app_id appropirately
<provider android:authorities="com.facebook.app.NativeAppCallContentProvider694100583997756" android:name="com.facebook.NativeAppCallContentProvider" android:exported="true"/>
Add Internet and ACCESS NETWORK STATE Permission under : AndroidManifest.xml > Application Tab > Application Nodes > User Permissions
android.permission.INTERNET android.permission.ACCESS_NETWORK_STATE
Now if you run the program will get Jar mismatch! Fix your dependencies Error, to fix this issue you need to delete android-support-v4.jar under Your Project libs folder and place here the same file from FacebookSDK project's libs file.
