Crash on Bar code scan

[achinverma]

Hi , iam using your lib to scan barcode and i am using in fragment but
Scan barcode 4-5 times continuosly , sometimes instead of calling on activity result of fragment , on destroy calls.

public void onPreviewFrame(byte[] data, Camera camera) {
Camera.Parameters parameters = camera.getParameters();
Camera.Size size = parameters.getPreviewSize();

Image barcode = new Image(size.width, size.height, "Y800");
barcode.setData(data);

int result = mScanner.scanImage(barcode);

if (result != 0) {
mCamera.cancelAutoFocus();
mCamera.setPreviewCallback(null);
mCamera.stopPreview();
mPreviewing = false;
SymbolSet syms = mScanner.getResults();
for (Symbol sym : syms) {
String symData = sym.getData();
if (!TextUtils.isEmpty(symData)) {
Log.d(""+getClass(), "Scan barcode zbar scanner activity symData ***** " + symData);
Intent dataIntent = new Intent();
dataIntent.putExtra(SCAN_RESULT, symData);
dataIntent.putExtra(SCAN_RESULT_TYPE, sym.getType());
dataIntent.putExtra("INTERFACE_ID", interface_id);
setResult(Activity.RESULT_OK, dataIntent);
finish();
Log.d(""+getClass(), "Scan barcode zbar scanner activity symData111 ***** " + symData);
break;
}
}
}
}
