Android 接入Facebook分享功能

Android接入Facebook的分享

首先注册成为Fackbook开发者。https://developers.facebook.com

登陆到Facebook开发者后台然后点击"Apps" -> "Add a New App",输入App的名称“TeshShare”并选择分类,进行创建App

点击"Apps" -> "TestShare" ,就是我们刚才创建的App ,然后点击左侧的"Settings",进行相关的信息设置.

配置如下信息

(1). App的包名 com.test.share

(2). App的主Activity名字 com.test.share.MainActivity

(3). 签名文件的哈希值

eclipse debug签名hash值获取方法打开mac终端输入下面的命令

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

正式签名需要在程序中添加如下代码签名打包后查看控制台的输入值将这个值复制到后台进行配置。这个我们先使用Eclipse的debug签名哈希值。代码如下

/***获取签名Key的hash值facebook后台需要添加这个如果这个值跟后台的对不上那么会分享失败提示KeyHash值不对*/publicstaticvoidgetKeyHash(Contextctx){//Addcodetoprintoutthekeyhashtry{PackageInfoinfo=ctx.getPackageManager().getPackageInfo("com.test.share",//替换成你app的包名PackageManager.GET_SIGNATURES);for(Signaturesignature:info.signatures){MessageDigestmd=MessageDigest.getInstance("SHA");md.update(signature.toByteArray());Log.d("KeyHash:",Base64.encodeToString(md.digest(),Base64.DEFAULT));}}catch(Exceptione){}}

4.下载 Facebook SDK 如下图。讲facebook导入到Eclipse中。将导入的facebook做为lib工程add到我们的工程中

乖乖的打开×××,到Google Play上去安装Facebook吧。

5.配置facebook appid和网络访问权限

在strings.xml中添加

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

在AndroidManifest.xml添加

6.列出MainActivity的代码

packagecom.test.share;importandroid.app.Activity;importandroid.content.Intent;importandroid.os.Bundle;importandroid.util.Log;importandroid.view.Menu;importandroid.view.View;importandroid.widget.Toast;importcom.facebook.UiLifecycleHelper;importcom.facebook.widget.FacebookDialog;publicclassMainActivityextendsActivity{privateUiLifecycleHelperuiHelper;@OverrideprotectedvoidonCreate(BundlesavedInstanceState){super.onCreate(savedInstanceState);uiHelper=newUiLifecycleHelper(this,null);uiHelper.onCreate(savedInstanceState);setContentView(R.layout.activity_main);finalActivityactivity=this;findViewById(R.id.button1).setOnClickListener(newView.OnClickListener(){@OverridepublicvoidonClick(Viewarg0){//判断是否安装Facebookif(FacebookDialog.canPresentShareDialog(activity,FacebookDialog.ShareDialogFeature.SHARE_DIALOG)){FacebookDialogshareDialog=newFacebookDialog.ShareDialogBuilder(activity).setLink("www.baidu.com").setApplicationName("TestShare").setName("test").setCaption("thisisatestshare").build();uiHelper.trackPendingDialogCall(shareDialog.present());}else{Toast.makeText(activity,"Facebookappisnotinstalled",Toast.LENGTH_SHORT).show();}}});}@OverrideprotectedvoidonActivityResult(intrequestCode,intresultCode,Intentdata){super.onActivityResult(requestCode,resultCode,data);uiHelper.onActivityResult(requestCode,resultCode,data,newFacebookDialog.Callback(){@OverridepublicvoidonError(FacebookDialog.PendingCallpendingCall,Exceptionerror,Bundledata){Log.e("Activity",String.format("Error:%s",error.toString()));}@OverridepublicvoidonComplete(FacebookDialog.PendingCallpendingCall,Bundledata){Log.i("Activity","Success!");}});}@OverrideprotectedvoidonResume(){super.onResume();uiHelper.onResume();}@OverrideprotectedvoidonSaveInstanceState(BundleoutState){super.onSaveInstanceState(outState);uiHelper.onSaveInstanceState(outState);}@OverridepublicvoidonPause(){super.onPause();uiHelper.onPause();}@OverridepublicvoidonDestroy(){super.onDestroy();uiHelper.onDestroy();}@OverridepublicbooleanonCreateOptionsMenu(Menumenu){//Inflatethemenu;thisaddsitemstotheactionbarifitispresent.getMenuInflater().inflate(R.menu.main,menu);returntrue;}}

7.运行测试

点击发布提示“分享成功”

8.注意的问题

(1). 分享时候的AppName问题

//setApplicationName("必须是你后台设置的AppName")FacebookDialogshareDialog=newFacebookDialog.ShareDialogBuilder(activity).setLink("www.baidu.com").setApplicationName("TestShare").setName("test").setCaption("thisisatestshare").build();

(2). 发布的时候签名哈希值在后台要改为正式签名的哈希值

(3). 关于混淆

-keepclasscom.facebook.**{*;}-keepattributesSignature

(4).正式发布的时候后台要改一个状态

"Status&Review" -> "Do you want to meak this app and all its live...public ? " -> "YES"
