根据视频说明,我无法在全屏模式下运行Android应用.当它试图运行时,应用程序崩溃并出现错误.

"You need to use a Theme.AppCompat theme (or descendant) with this activity

清单文件

样式文件

<resources>

    <item name="colorAccent">@color/colorAccent</item>
</style>

可能有用的部分MainActivity

public class MainActivity extends AppCompatActivity {

因此，我的代码可以很好地编译，但是每当我尝试运行该程序时，它就会出现段错误。我通过gdb运行它并得到了这组错误：

terminate called after throwing an instance of 'std::logic_error'
   what():  basic_string::_S_construct null not valid

Program received signal SIGABRT, Aborted.
0x00007ffff722bcc9 in __GI_raise (sig=sig@entry=6) at ../nptl/sysdeps/unix/sysv/linux/raise.c:56
56  ../nptl/sysdeps/unix/sysv/linux/raise.c: No such file or directory.

这是我的代码，如果有帮助的话：

using namespace std;
#include <iostream>
#include <vector>
#include <cmath>
#include<fstream>
#include <cstdlib>
#include <utility>
#include <string>

class Page
{
  public:
    int TimeStamp;
    int ProgramOwner;
    int LocalPageNumber;

};

//Pair: first entry is local page, second entry is global page
//Second entry: 1 if in main memory, 0 if …
