Question

我正在努力将Camera2 api集成到我的应用程序中。当我从纵向模式切换到横向时，它会抛出异常

<div class="wrapper">
  <span class="button">Star</span>
  <div class="popup">
    <p>Option 1</p>
    <p>Option 2</p>
    <p>Option 3</p>
    <p>Option 4</p>
    <p>Option 5</p>
    <p>Option 6</p>
    <p>Option 7</p>
    <p>Option 8</p>
    <p>Option 9</p>
  </div>
</div>

Answer 1

我遇到了类似的问题，这对我有所帮助。如果您一直在参考Sample app，则应通过重写onClosed（CameraDevice）方法来停止CameraDevice.StateCallback中的线程：

 mCameraDevice.createCaptureSession(outputSurfaces,
                new CameraCaptureSession.StateCallback() {

                    @Override
                    public void onClosed(@NonNull CameraCaptureSession session) {
                        super.onClosed(session);
                        stopBackgroundThread();
                    }

在我的情况下，此错误之前是

2020-12-15 18:31:55.703 5079-5079/com.android.example.camera2.video W/CameraDevice-JV-0: Stream configuration failed due to: createStream:1008: Camera 0: Surface already has a stream created for it (ID 0)
2020-12-15 18:31:55.704 5079-5079/com.android.example.camera2.video E/CameraCaptureSession: Session 0: Failed to create capture session; configuration failed

问题是我将曲面添加到列表中并将其添加为目标，但没有清除它。我也是setRepeatingRequest之前updateRepeatingRequest的{{1}}

清除override fun onConfigured(s: CameraCaptureSession) {中的曲面并删除其他的updateRepeatingRequest对其进行了修复。

Android - CameraDevice已经关闭
