qt for android 重新编译Qt6Android.jar

编译Qt6Android.jar

qt版本：6.7
进入到Qt源码目录

<你的qt目录>\Src\qtbase\src\android\jar\src\org\qtproject\qt\android

打开cmd 输入

javac -Xlint:deprecation -classpath <你的安卓sdk目录>\android.jar *.java ./accessibility/*.java  ./extras/*.java

将编译的.class文件直接拖进.jar文件里(.jar文件用压缩包形式打开)

<你的qt目录>\<你的Qt版本>\android_arm64_v8a\jar\Qt6Android.jar

qt 6.7 WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES样式问题

如果设置了WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES样式
APP退出到后台在回到APP，会发现刘海（安全）区域不再被填充
在QtDisplayManager.java代码中发现

public void setSystemUiVisibility(int systemUiVisibility)
    {
        if (m_systemUiVisibility == systemUiVisibility)
            return;

        m_systemUiVisibility = systemUiVisibility;

        int systemUiVisibilityFlags = View.SYSTEM_UI_FLAG_VISIBLE;
        switch (m_systemUiVisibility) {
            case SYSTEM_UI_VISIBILITY_NORMAL:
                m_activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
                m_activity.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
                    m_activity.getWindow().getAttributes().layoutInDisplayCutoutMode =
                            WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_NEVER;
                }
                break;
            case SYSTEM_UI_VISIBILITY_FULLSCREEN:
                m_activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
                m_activity.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
                systemUiVisibilityFlags = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                        | View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                        | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                        | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                        | View.SYSTEM_UI_FLAG_FULLSCREEN
                        | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
                        | View.INVISIBLE;
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
                    m_activity.getWindow().getAttributes().layoutInDisplayCutoutMode =
                            WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_DEFAULT;
                }
                break;
            case SYSTEM_UI_VISIBILITY_TRANSLUCENT:
                m_activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN
                        | WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION
                        | WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
                m_activity.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
                    m_activity.getWindow().getAttributes().layoutInDisplayCutoutMode =
                            WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_ALWAYS;
                }
                break;
        }
        m_activity.getWindow().getDecorView().setSystemUiVisibility(systemUiVisibilityFlags);
    }

代码段

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
                    m_activity.getWindow().getAttributes().layoutInDisplayCutoutMode =
                            WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_DEFAULT;
                }

这里强制将布局设置为了WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_DEFAULT
不知道为什么这样操作

修改代码

if (m_activity.getWindow().getAttributes().layoutInDisplayCutoutMode != 
                        WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES) {
                        m_activity.getWindow().getAttributes().layoutInDisplayCutoutMode =
                            WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_DEFAULT;
                    }

APP商店退回用户未点击《用户协议》就启动传感器

在QtMultimediaUtils.java中
代码

static public void setContext(Context context)
    {
        m_context = context;
        m_orientationListener = new OrientationListener(context);
    }

OrientationListener创建时就会启动加速度器, 用于辨别屏幕方向
就只有一个APP商店认为触犯了用户隐私被退回了
修改就是此处的new屏蔽掉
在需要调用m_orientationListener 的地方加上

if (!m_orientationListener)
            m_orientationListener = new OrientationListener(m_context);
