public staticvoid init(Application currentApplication) {android中利用application類中的ActivityLifecycleCallbacks接口實現activity的管理及界面傳值
簡化界面跳轉，和界面之間的傳值和獲取
使用方法：
MainActivity中
AContext.push(SecondActivity.class, "SecondActivity");//跳轉到SecondActivity中並傳遞一個字符串
String msg = AContext.getPushData();// SecondActivity中獲取數據
ThreeActivity中：
AContext.pull("2", 3);//關閉當前activity並傳遞兩個參數，
在SecondActivity獲取返回的數據
if (AContext.getPullData() != null) {
// 獲取ThreeActivity返回的數據
String one = AContext.getPullData(0);
int two = AContext.getPullData(1);
AContext.show("第一頁傳過來的值：" +one + ";" + two);
}

}
在AContext類中初始化ActivityManager並註冊
sApplication =currentApplication;
sActivityManager =new ActivityManager();
sApplication.registerActivityLifecycleCallbacks(sActivityManager);
}
通過application註冊監聽activity
public class InitApplicationextends Application {
@Override
public void onCreate() {
super.onCreate();
/**
* 初始化註冊activity生命週期監聽
*/
AContext.init(this);
}
}
最後在AndroidManifest.xml中註冊application
