android_native_surface's Issues

ScreenRecorder can't record surface drawing

System Screen Recoder or any other screen recorder from playstore can't record surface drawing , while screenshot can capture the drawing .

Android : 13
ROM : MIUI EU (Redmi Note 12 Turbo)

More information --

Backend : OpenGLES 3
Also tried in Android-13 ,ROM - Derpfest (Redmi Note 5 Pro)

And apparently in some android 13 device screen recording working as expected .

卡触摸

安卓14卡触摸

可以兼容安卓14吗

1 关于屏幕反转崩溃

原来的获取屏幕信息代码displayInfo = externFunction.getDisplayInfo();
这个东东在我的设备上屏幕反转就会崩溃
我目前是用了dumpsys display命令和wm size命令来获取屏幕信息
-_-

图中的显示另一个手机画面有安卓代码参考吗

如题，感谢

1 如何导入到安卓项目呢

旋转屏幕崩溃

如果增加字体，那旋转屏幕就会马上崩溃
bool DrawVulkan::initDraw(uint32_t _screen_x, uint32_t _screen_y, int flags, bool log)

ImFontConfig font_cfg;
font_cfg.SizePixels = 22.0f;
io.Fonts->AddFontDefault(&font_cfg);
io.Fonts->AddFontFromMemoryTTF((void *) OPPOSans_H, OPPOSans_H_size, 35.0f, NULL, io.Fonts->GetGlyphRangesChineseFull());

Pointer tag for 0x5c5cad55e8 was truncated, see 'https://source.android.com/devices/tech/debug/tagged-pointers'.

程序崩溃

竖屏转横屏时发生字段错误然后程序退出
手机是小米8 ndk版本是ndk-21

关于getTouchScreenDevice函数的bug

位于touch.cpp中的getTouchScreenDevice函数在一些设备上，会返回错误的路径
例如在我的小米平板5pro上，符合getTouchScreenDevice函数筛选条件的输入设备有两个：
一个是event4，也就是我的物理触摸屏
这是我的物理触摸屏节点的信息

 add device 11: /dev/input/event4
  bus:      001c
  vendor    0000

这个是另一个节点的信息

add device 1: /dev/input/event12

  input props:
    INPUT_PROP_POINTER

我也不知道这个节点是干什么的，但是getTouchScreenDevice函数却获取到了这个event
建议额外增加触摸点数的检测就可以解决这个问题

旋转屏幕后会崩溃

旋转屏幕后会崩溃，本来还以为是库里面导出的获取屏幕信息函数有bug，还特意自己重写了，结果发现不是。。。

经过初步排查

   if (orientation != displayInfo.orientation)
  {
//      externFunction.setSurfaceWH(displayInfo.width, displayInfo.height);
      
      shutdown();
      
      initDraw(true);

      orientation = displayInfo.orientation;
      cout << " width:" << displayInfo.width << "height:" << displayInfo.height << " orientation:"
           << displayInfo.orientation << endl;
  }

是在执行shutdown();时进程死了
