Zxing library implementation: and the bottom part for getting the result after scanning.

When the scan operation from com.google.zxing.client.android.SCAN finishes, I want to return the result and print the scanned object, so I used the onActivityResult method. But the error occurs on the Toast line.

public void onActivityResult(int reqCode, int resCode, Intent intent1) {
if (requestCode == 0) {
    if (resCode == RESULT_OK) {
        String contents = intent.getStringExtra("SCAN_RESULT");
        String format = intent.getStringExtra("SCAN_RESULT_FORMAT");
        Toast toast = Toast.makeText("Content:" + contents + " Format:" + format, Toast.LENGTH_LONG);
        toast.show();
    }
}

      

        
        
        
      

    

}
