Activity生命周期的全局管理

Application里面添加：

this.registerActivityLifecycleCallbacks(new ActivityLifecycleCallbacks() {
    @Override
    public void onActivityCreated(Activity activity, Bundle savedInstanceState) {
        AppManager.getAppManager().addAliveActivity(activity);
        System.out.println("oncreate:" + activity);
    }

    @Override
    public void onActivityStarted(Activity activity) {
        System.out.println("onstart:" + activity);
    }

    @Override
    public void onActivityResumed(Activity activity) {
        AppManager.getAppManager().addFrontActivity(activity);
    }

    @Override
    public void onActivityPaused(Activity activity) {
        AppManager.getAppManager().removeFrontActivity(activity);

    }

    @Override
    public void onActivityStopped(Activity activity) {

    }

    @Override
    public void onActivitySaveInstanceState(Activity activity, Bundle outState) {

    }

    @Override
    public void onActivityDestroyed(Activity activity) {
        AppManager.getAppManager().removeAliveActivity(activity);
    }
});
