Android : CameraX 在 JitsiMeetView 之后不打开

Question

我在我的应用程序上使用 CameraX，我也在使用 JistiMeetView。当我启动应用程序时，我可以打开包含 CameraX 的 activity 并且相机可以启动。当我用JitsiMeetView打开activity时，我正确地加入了房间，但是当我退出jitsiactivity并回到摄像头activity时，摄像头无法启动。所以我认为jitsi保留了相机资源，但我不知道如何关闭所有资源。

这是我销毁jitsi时的代码activity:

@Override
protected void onDestroy() {
    jitsiMeetView.leave();
    jitsiMeetView.dispose();
    super.onDestroy();
}

摄像头activity 启动摄像头的代码：

 private fun startCamera(lensFacing: Int) {

        val cameraProviderFuture = ProcessCameraProvider.getInstance(this)

        cameraProviderFuture.addListener(Runnable {
            // Used to bind the lifecycle of cameras to the lifecycle owner
            val cameraProvider: ProcessCameraProvider = cameraProviderFuture.get()

            preview = Preview.Builder().build()
                    .also {
                it.setSurfaceProvider(findViewById<PreviewView>(R.id.phototake_camera_view).surfaceProvider)
            }

            imageCapture = ImageCapture.Builder().setCaptureMode(ImageCapture.CAPTURE_MODE_MINIMIZE_LATENCY)
                    .build()

            imageAnalyzer = ImageAnalysis.Builder()
                    .build()

            // Select back camera
            val cameraSelector = CameraSelector.Builder().requireLensFacing(lensFacing).build()

            try {
                // Unbind use cases before rebinding
                cameraProvider.unbindAll()

                // Bind use cases to camera
                cameraProvider.bindToLifecycle(this, cameraSelector, preview, imageCapture, imageAnalyzer)

            } catch (exc: Exception) {
                Log.e(TAG, "Use case binding failed", exc)
            }

        }, ContextCompat.getMainExecutor(this))
    }

并且在我停止 jitsi 视图时在日志中也有这个，它仍然存在：

我只为 CameraX 使用 Kotlin activity

我找到了解决方案。

关注官网后：https://jitsi.github.io/handbook/docs/dev-guide/dev-guide-android-sdk

关于 Jisti Activity 的 Activity 生命周期，我已经忘记了所有 JitsiMeetActivityDelegate.onHost...(this);。我刚刚添加了它们，现在可以正常工作了。
