android - How to delay SurfaceView setup with CameraSource? -


i have 2 activities :

  • a surfaceview receiving feed camerasource
  • b simple form, filled info activity scan

i'd close activity on scan completion , animate activity b appearance. seems surfaceview or camerasource somehow blocking ui thread , preventing smooth transition.

activity :

...  @override public void surfacedestroyed(surfaceholder holder) {     mcamerasource.stop(); }  ...  @override public void receivedetections(detector.detections<barcode> detections) {     if (misreadyfortransfer) {         return;     }      sparsearray<barcode> barcodes = detections.getdetecteditems();     if (barcodes.size() == 0 || barcodes.valueat(0).displayvalue.equals(mlastresult)) {         return;     }      mlastresult = barcodes.valueat(0).displayvalue;      if (mlastresult.substring(0, 3).equals("xxx")) {         misreadyfortransfer = true;          transferactivity.start(this, scanresult.getresultfromscan(mlastresult));          finish();     } }

thanks time.
