Take multiple pictures in capturesession with an interval?

Question

I'm trying to take 10 with an interval of about 1 second using the camera2 API.

I have the following createCaptureSession to successfully create 10 capture requests, but where do I add the interval?

cameraDevice.createCaptureSession(outputSurfaces, new CameraCaptureSession.StateCallback() {
    @Override
    public void onConfigured(CameraCaptureSession session) {
      try {
        for (int i =0; i < 10;i++) {
          session.capture(captureBuilder.build(), captureListener, null);
        }
       } catch (CameraAccessException e) {
         e.printStackTrace();
       }
     }

     @Override
     public void onConfigureFailed(CameraCaptureSession session) {
       System.out.println("ConfigurationFailed");
     }
   }, mBackgroundHandler);

I have done this using Camare2Basic example. You have to modify lockFocus() function add something like this:

try { Thread.sleep(CAPTURE_WAITING_TIME_MILISECOND); } catch (InterruptedException e) { e.printStackTrace(); }

on onImageAvailable you need to call takePicture() if image count is not 10. or it is better to call it on ImageSaver's callback.

The interval cannot be exact time. it may change depending on the processing time.

Hope it helps
