我需要在我的Android程序中添加C/C++代码,我需要LLDB,CMake和NDK.我在SDK管理器中找到了LLDB和NDK,但那里缺少CMake.我尝试从CMake官方网站手动下载它,发现对于Android我们需要SDK定制的CMake.

如你所见,没有像CMake这样的选择.

我在哪里可以找到适用于Android的CMake版本？

我在网站上尝试过CMake,在ndk-bundle/build文件夹中找到了一个,但两者都给出了同样的错误.可以用它做什么以及如何解决问题？

Build command failed.

我有这个代码

@FXML
private ToggleButton tb1;
@FXML
private ToggleButton tb2;
@FXML
ToggleGroup group = new ToggleGroup();

String cpuLoad1 ="D:/myWorkspace/TestAttacks/input_folder/app_debug.apk";
String cpuLoad2 = "D:/myWorkspace/TestAttacks/input_folder/cpuLoad1.apk";   

@FXML
private void onToggleClick(){

    tb1.setUserData(cpuLoad1);
    tb1.setToggleGroup(group);
    tb2.setUserData(cpuLoad2);
    tb2.setToggleGroup(group);

    ChangeListener<Toggle> cLt = new ChangeListener<Toggle>(){
        public void changed(ObservableValue<? extends Toggle> ov,
                Toggle toggle, Toggle new_toggle){
            if (new_toggle != null){
                System.out.println(group.getSelectedToggle().getUserData().toString());

            }else{
                System.out.println("hello no");
            }
        }
    };

    group.selectedToggleProperty().addListener(cLt);

}

尽管我仍然没有使用用户数据，但问题是，每当我单击切换按钮时，我都会按升序获得所需的输出。

这是输出：

hello no                                                 //click2
