Java与移动设备_画摄

Android应用QQ第三方登录接入流程：
1.开发者注册
2.移动应用接入申请
获得对应的appid和appkey
3.移动应用开发
开发流程概述：
3.1新建工程并导入SDK的jar文件
3.2配置AndroidManifest
3.3创建实例并实现回调
3.4调用QQ登录接口

1.添加权限：
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
2.添加活动：
<activity
android:name="com.tencent.tauth.AuthActivity"
android:launchMode="singleTask"
android:noHistory="true" >
<intent-filter>
<action android:name="android.intent.action.VIEW" /> <category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
