Android 讀取<meta-data>元素中的資料

眾所周知, 每個組件都有<meta-data>元素, 用於接收一些外部資料(eg: appKey), 那其中的值應該怎麼讀取呢. 

1> Application

ApplicationInfo info = ="application meta data value:" + info.metaData.getString("application_meta_data"));

2> Activity 

          </activity>

ActivityInfo info = ="activity meta data value:" + info.metaData.getString("activity_meta_data"));

 3> Service

              </service>

ServiceInfo info = =, PackageManager.GET_META_DATA);  //    } "service meta data value:" + info.metaData.getString("service_meta_data"));

 4> BroadcastReceiver

ActivityInfo info = = ComponentName(, MyReceiver."receiver meta data value:" + info.metaData.getString("receiver_meta_data"));

 

::: V/MainActivity(::: V/MainActivity(::: V/MainActivity(::: V/MainActivity(): receiver meta data value:receiver_meta_data_value
