下载SDK

https://github.com/sinaweibosdk/weibo_android_sdk

获取欲接入应用的签名

使用sdk中 app_signatures.apk 获取应用的签名

在微博开放平台注册应用

http://open.weibo.com/
注册时需要提供应用的签名

在项目中导入weiboSDK

• 添加权限

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<!-- 用于调用 JNI -->
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

• 添加授权页activity

<!-- 必须注册在微博授权，分享微博时候用到 -->
<activity android:name="com.sina.weibo.sdk.component.WeiboSdkBrowser"
          android:configChanges="keyboardHidden|orientation"
          android:windowSoftInputMode="adjustResize"
          android:exported="false" >
</activity>

• 获取token
  token是服务器标识用户的方式，获取token后才能进行发微博等操作

mAccessToken = AccessTokenKeeper.readAccessToken(MainActivity.this);
if (!mAccessToken.isSessionValid()) {
    AuthInfo authInfo = new AuthInfo(this, Constants.APP_KEY, Constants.REDIRECT_URL, Constants.SCOPE);
    mSsoHandler = new SsoHandler(this, authInfo);
    mSsoHandler.authorize(new WeiboAuthListener() {
        @Override
        public void onComplete(Bundle bundle) {
            Oauth2AccessToken accessToken = Oauth2AccessToken.parseAccessToken(bundle);
            if (accessToken.isSessionValid()) {
                AccessTokenKeeper.writeAccessToken(MainActivity.this, accessToken);
                Log.d("Oauth2AccessToken", accessToken.toString());
            } else {
                Log.w("Oauth2AccessToken", "session is empty");
            }
        }

        @Override
        public void onWeiboException(WeiboException e) {
            Toast.makeText(MainActivity.this,
                "Auth exception : " + e.getMessage(), Toast.LENGTH_LONG).show();
        }

        @Override
        public void onCancel() {
            Toast.makeText(MainActivity.this,
                "请登录", Toast.LENGTH_LONG).show();
        }
    });
}

AccessTokenKeeper是SDK中带的保存token的类，使用SharedPreferences存储
