关闭 SDK 中的Activity ActivityLifecycleCallbacks

项目在开发的时候 有单点登录的功能要做
项目中有 支付宝 微信充值 主要是 支付宝充值 如手机中没有支付宝应用 就在应用内打开h5的支付宝充值页面 这就涉及到 第三方sdk 中的activity关闭问题

注册 ActivityLifecycleCallbacks 监听应用内所有 Activity的生命周期

public class GApplication extends Application {
    //记录当前栈里所有activity
    private List activities = new ArrayList();
    //记录需要一次性关闭的页面
    private List activitys = new ArrayList();

    private static GApplication instance;

    }

        instance = this;
        //禁止默认的页面统计方式
        MobclickAgent.openActivityDurationTrack(false);
        //debug模式
        MobclickAgent.setScenarioType(getApplicationContext(), MobclickAgent.EScenarioType.E_UM_NORMAL);
        CrashReport.initCrashReport(getApplicationContext(), "73b6bbb172", true);
