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();
}
