Android hardware camera fire intent after onPictureTaken -

i have implemented own camera preview layout , functionality. anyway, when press button take picture calls onpicturetaken method, intent not fired. intent declared correctly in manifest file.

here code , hope knows here in order fire intent.

public class takepicture extends activity { private preview mpreview; private camera mcamera; private int numberofcameras; private int defaultcameraid; private context context;  autofocuscallback myautofocuscallback = new autofocuscallback() {     @override     public void onautofocus(boolean arg0, camera arg1) {         // buttontakepicture.setenabled(true);     } };  picturecallback mypicturecallback_jpg = new picturecallback() {     @override     public void onpicturetaken(byte[] arg0, camera arg1) {         //savepicture(arg0);          intent ia = new intent(context, previewphoto.class);

the line ia.putextra("image", arg0) causing error failed binder transaction. must pass image path, not byte[] of data new intent :)
