【移动应用开发技术】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。

登陆到Facebook开发者后台然后点击"Apps"->"AddaNewApp",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

eclipsedebug签名hash值获取方法

打开mac终端输入下面的命令keytool-exportcert-aliasandroiddebugkey-keystore~/.android/debug.keystore|opensslsha1-binary|opensslbase64

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

4.下载FacebookSDK

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GooglePlay上去安装Facebook吧。

5.配置facebookappid和网络访问权限

在strings.xml中添加

<string

name

="facebook_app_id">365646333616560</string>在AndroidManifest.xml添加

<meta-data

android:name="com.facebook.sdk.ApplicationId"

android:value="@string/facebook_app_id"/>

<uses-permission

android:name="android.permission.INTERNET"

/>6.列出MainActivity的代码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;

com.facebook.UiLifecycleHelper;

import

com.facebook.widget.FacebookDialog;

public

class

MainActivity

extends

Activity

{

private

UiLifecycleHelper

uiHelper;

@Override

protected

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()

{

@Override

public

void

onClick(View

arg0)

{

//

判断是否安装Facebook

if

(FacebookDialog.canPresentShareDialog(activity,

FacebookDialog.ShareDialogFeature.SHARE_DIALOG))

{

FacebookDialog

shareDialog

=

new

FacebookDialog.ShareDialogBuilder(

activity).setLink("")

.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();

}

}

});

}

@Override

protected

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!");

}

});

}

@Override

protected

void

onResume()

{

super.onResume();

uiHelper.onResume();

}

@Override

protected

void

onSaveInstanceState(Bundle

outState)

{

super.onSaveInstanceState(outState);

uiHelper.onSaveInstanceState(outState);

}

@Override

public

void

onPause()

{

super.onPause();

uiHelper.onPause();

}

@Override

public

void

onDestroy()

{

super.onDestroy();

uiHelper.onDestroy();

}

@Override

public

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.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")

FacebookDialog

shareDialog

=

new

FacebookDialog.ShareDialogBuilder(

activity).setLink("")

.setApplicationName("TestShare").setName("test")

.setCaption("this

is

a

test

share

").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
