I'm not using any other libraries, I'm just sending a Bitmap to setImage() in TessBaseAPI. For image capture, I used the camera code from the ZXing Barcode Scanner.
During the "continuous preview," the OCR has already been performed by the time you see the preview text, so there's the impression of fast OCR after you click the shutter button, but really it's already been performed by that point. During the preview, the "time required" number you see at the bottom of the screen is just the time needed for setImage() + wordConfidences() + meanConfidence(). I think you can make it work efficiently using setImage() and storing as a String before packaging into JSON.
