   Configure the following information

   (1). App's package name Com.test.share

   (2). The app's main activity name Com.test.share.MainActivity

   (3). Hash value of the signature file

   Eclipse Debug Signature Hash value get method open Mac terminal enter the following command

   keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64

   The formal signature needs to be added to the program by adding the following code signature after packaging, look at the console input values to copy this value to the background for configuration. Let's start with the debug signature hash of Eclipse. The code is as follows

   
   

6. /** *  get the hash value of the signature key Facebook backstage needs to add this if this value is not on the back of the background, then it will share the failure prompt Key hash value is not  */public static  void getkeyhash (CONTEXT CTX) {// add code to print out the  Key hash    try {        packageinfo  info = ctx.getpackagemanager (). Getpackageinfo (                  "Com.test.share",  //Replace with your app's package name                  packagemanager.get_signatures);         for  (Signature signature : info.signatures)  {            messagedigest md =  messagedigest.getinstance ("SHA");             md.update (signature.tobytearRay ());             LOG.D ("KeyHash:",  Base64.encodetostring (Md.digest (),  base64.default));             }    } catch  (exception e)  {         }}

4. Download the Facebook SDK for example. Tell Facebook to import into eclipse. Add the imported Facebook as a Lib project to our project

Just turn on the VPN and install Facebook on Google Play.

5. Configure Facebook AppID and network access

Add in Strings.xml

<string name = "facebook_app_id" >365646333616560</string>

Add in Androidmanifest.xml

<meta-data android:name= "Com.facebook.sdk.ApplicationId" android:value= "@string/facebook_app_id"/> < Uses-permission android:name= "Android.permission.INTERNET"/>

6. Listing Mainactivity's Code

package com.test.share;import android.app.activity;import android.content.intent;import  android.os.bundle;import android.util.log;import android.view.menu;import android.view.view; import android.widget.toast;import com.facebook.uilifecyclehelper;import  com.facebook.widget.facebookdialog;public class mainactivity extends activity { private uilifecyclehelper uihelper; @Overrideprotected  void oncreate (bundle  savedinstancestate)  {super.oncreate (savedinstancestate); Uihelper = new uilifecyclehelper ( This, null);     uihelper.oncreate (savedinstancestate); Setcontentview ( R.layout.activity_main); Final activity  activity = this;findviewbyid (R.id.button1). Setonclicklistener (New view.onclicklistener ()  {@Overridepublic  void onclick (View arg0 )  {//  determine if facebookif  is installed (facebookdialog.canpresentsharediaLog (Activity,facebookdialog.sharedialogfeature.share_dialog))  {facebookdialog sharedialog =  new facebookdialog.sharedialogbuilder (activity). Setlink ("www.baidu.com"). Setapplicationname (" TestShare "). SetName (" Test "). Setcaption (" this is  a test share  "). Build (); Uihelper.trackpendingdialogcall (Sharedialog.present ());}  else {toast.maketext (activity,  "facebook app is not installed", Toast.length_short). Show ();}});} @Overrideprotected  void onactivityresult (int requestcode, int resultcode, intent  data)  {    super.onactivityresult (requestcode, resultcode, data);     uihelper.onactivityresult (requestcode, resultcode, data, new  Facebookdialog.callback ()  {         @Override          public void onerror (FacebookdiaLog. Pendingcall pendingcall, exception error, bundle data)  {             LOG.E ("Activity",  string.format ("error: %s",  Error.tostring ()));        }          @Override         public void oncomplete ( Facebookdialog.pendingcall pendingcall, bundle data)  {             LOG.I ("Activity",  "success!");         }    });} @Overrideprotected  void onresume ()  {    super.onresume ();     uihelper.onresume ();} @Overrideprotected  void onsaveinstancestate (bundle outstate)  {     Super.onsaveinstancestate (outstate);     uihelper.onSaveinstancestate (outstate);} @Overridepublic  void onpause ()  {    super.onpause ();     uihelper.onpause ();} @Overridepublic  void ondestroy ()  {    super.ondestroy ();     uihelper.ondestroy ();} @Overridepublic  boolean oncreateoptionsmenu (Menu menu)  {// inflate the menu ; this adds items to the action bar if it is  Present.getmenuinflater (). Inflate (r.menu.main, menu); return true;}}

7. Run the test

650) this.width=650; "src=" http://s3.51cto.com/wyfs02/M02/54/7C/wKioL1SEZhXQGIvbAAF8lNOD1vI439.jpg "title=" 7.png " alt= "Wkiol1sezhxqgivbaaf8lnod1vi439.jpg"/>

Click Post to "Share success"

8. Issues of attention

(1). appname issues when sharing

Setapplicationname ("must be the appname you set in the background") Facebookdialog Sharedialog = new Facebookdialog.sharedialogbuilder ( Activity). Setlink ("www.baidu.com"). Setapplicationname ("TestShare"). SetName ("Test"). Setcaption ("This is a test Share "). Build ();

(2). When the signature hash value is published in the background, the hash value is changed to a formal signature.

(3). About confusion

-keep class com.facebook.** {*;} -keepattributes Signature

(4). When the official release of the background to change a state

"Status&review", "Do you want to meak this app and all its live...public?", "Yes" 650) this.width=650; " Src= "Http://s3.51cto.com/wyfs02/M00/54/7E/wKiom1SEZ0jCrFuOAAG69LMwjxc623.jpg" title= "9.png" alt= " Wkiom1sez0jcrfuoaag69lmwjxc623.jpg "/>
