c++ - 黑莓模拟器 : ViewFinder starting failed 级联相机错误

Question

我正在尝试在 Blackberry Cascades 10.2 中打开相机

import bb.cascades.multimedia 1.0
import bb.multimedia 1.0
import bb.cascades 1.2
import bb.system 1.2
Page {
  titleBar: TitleBar {
     title: "QML Camera Sample App"
  }
  content : Camera {
     id: qmlCameraObj
     property bool photoBeingTaken
     onTouch: {
        if (photoBeingTaken == false) {
           photoBeingTaken = true;
           qmlCameraObj.capturePhoto();
        }
     }
     onCameraOpened: {
        qmlCameraObj.startViewfinder();
     }
     onCameraOpenFailed: {
        console.log("camera open failed")
     }
     onViewfinderStarted: {
       photoBeingTaken = false;
     }
     onViewfinderStartFailed: {
        console.log("view finder failed")
     }
     onPhotoCaptureFailed: {
        console.log("Photo capture failed")
        photoBeingTaken = false;
     }
     onPhotoSaveFailed: {
        console.log("Photo save failed")
        photoBeingTaken = false;
     }
     onPhotoSaved: {
        photoBeingTaken = false;
     }
     onCreationCompleted: {
        qmlCameraObj.open(CameraUnit.Front)
    }
  }
}

我还在 .pro 中添加了适当的库，并将这些行添加到我的 bar-descriptor.xml

<permission system="true">run_native</permission>
<permission>use_camera</permission>
<permission>access_shared</permission>

但是当我在模拟器上运行这段代码时，我在控制台中看到:view finder failed。 如果有人知道为什么取景器不启动，那将会很有帮助。

EDIT :似乎是模拟器。我下载了 Beta 10.2.1，它可以运行。

Answer 1

相机无法在模拟器中打开。在设备中运行它。
