如何使用Camera2删除图像中的GPS数据？

Question

[在旧的android相机api中，我们可以使用此方法删除图像中的GPS数据。（Camera.Parameters -> removeGpsData）

有人知道如何使用新的Android Camera2 API删除或禁用图像中的GPS数据吗？我们的目标是在图像的exif中拍摄没有gps信息的图片。

以下是我的代码：

private fun createCameraPreviewSession() {
    try {
        val texture = textureView.surfaceTexture

        // We configure the size of default buffer to be the size of camera preview we want.
        texture.setDefaultBufferSize(previewSize.width, previewSize.height)

        // This is the output Surface we need to start preview.
        val surface = Surface(texture)

        // We set up a CaptureRequest.Builder with the output Surface.
        previewRequestBuilder = cameraDevice!!.createCaptureRequest(
                CameraDevice.TEMPLATE_PREVIEW
        )
        previewRequestBuilder.addTarget(surface)

        // Here, we create a CameraCaptureSession for camera preview.
        cameraDevice?.createCaptureSession(Arrays.asList(surface, imageReader?.surface),
                object : CameraCaptureSession.StateCallback() {

                    override fun onConfigured(cameraCaptureSession: CameraCaptureSession) {
                        // The camera is already closed
                        if (cameraDevice == null) return

                        // When the session is ready, we start displaying the preview.
                        captureSession = cameraCaptureSession
                        try {
                            // Auto focus should be continuous for camera preview.
                            previewRequestBuilder.set(CaptureRequest.CONTROL_AF_MODE,
                                    CaptureRequest.CONTROL_AF_MODE_CONTINUOUS_PICTURE)
                            // Flash is automatically enabled when necessary.
                            setAutoFlash(previewRequestBuilder)

                            // Finally, we start displaying the camera preview.
                            previewRequest = previewRequestBuilder.build()
                            captureSession?.setRepeatingRequest(previewRequest,
                                    captureCallback, backgroundHandler)
                        } catch (e: CameraAccessException) {
                            Log.e(TAG, e.toString())
                        }

                    }

                    override fun onConfigureFailed(session: CameraCaptureSession) {
                        activity.showToast("Failed")
                    }
                }, null)
    } catch (e: CameraAccessException) {
        Log.e(TAG, e.toString())
    }

}
