Problem with camera android / java

When you open the Camera or attempt to take photo from the album, the intent that calls those functions is closed, I'll call with:

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                     File f = new File(android.os.Environment.getExternalStorageDirectory(), "temp.jpg");
                     intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
                     startActivityForResult(intent, 1);

and if I go back to Activity it is no longer there and as a consequence the onActivityResult () does not work. Detail in android 2.3 works and this error happens in 4.4.2.
