异常出现地方:

        //弹出提示对话框        dialog = new MyAlertDialog(AppManager.getAppManager().currentActivity());        dialog.tipDialog(getResources().getString(R.string.login_netFail), positiveBtnStr, negativeBtnStr, new MyAlertDialog.DialogCallBack() {            @Override            public void onEnSure() {                              Activity currentActivity = AppManager.getAppManager().currentActivity();                //跳转到登录页面                Intent intent = new Intent(currentActivity,LoginActivity.class);                startActivity(intent);                currentActivity.finish();            }

异常原因:

activity has leaked window 翻译过来是这个activity有被泄露的窗口

什么情况下会出现泄露的窗口?

一般是Dialog 或者popwindow 等这种基于一个activity才能弹出的窗口被泄露了.泄露的发生情况在一个处在弹出对话框的情况下 ,这个activity被finish了,但是这个弹出框没有被显式关闭,所以就被泄露了

异常解决:

      //弹出提示对话框        dialog = new MyAlertDialog(AppManager.getAppManager().currentActivity());        dialog.tipDialog(getResources().getString(R.string.login_netFail), positiveBtnStr, negativeBtnStr, new MyAlertDialog.DialogCallBack() {            @Override            public void onEnSure() {               //关闭对话框,这个一定要加上的,防止内存泄露                dialog.dismiss();                Activity currentActivity = AppManager.getAppManager().currentActivity();                //跳转到登录页面                Intent intent = new Intent(currentActivity,LoginActivity.class);                startActivity(intent);                currentActivity.finish();            }
