Question

我使用SDL2编写了一个C ++应用程序，我正在使用SDL提供的JNI处理程序：

https://www.libsdl.org/tmp/SDL/android-project/src/org/libsdl/app/SDLActivity.java

我只是将其扩展为在我的本机代码上调用main：

package com.test.testapp;

import org.libsdl.app.SDLActivity;

public class Testapp extends SDLActivity
{

}

我尝试过的一些事情：

如果我让main返回正常，我会注意到Android抛出了一个UI错误而我的应用程序仍在运行
在我的原生应用程序中添加一些关机处理后：

-

 SQL_Quit();
   std::exit(0);

-

这似乎根据logcat杀死了进程：

但是，在执行此操作后，我注意到我的应用程序窗口仍然存在于Android窗口历史记录中。我不确定这个的正确用语是什么，但我设备上的方形按钮给了我所有打开窗口的列表。当我从这个列表中选择我的应用程序时，它实际上会重新启动它（因为它被杀死了）但是我想从这里删除窗口，因为它给出了它仍在运行的外观。

如何在Android（SDL2）上干净地退出jni应用程序
