after clicking the button, it crashes directly and reports the following error:

< H2 > my guess < / H2 >

is in the button trigger code:

intent.putExtra(Constant.INTENT_ZXING_CONFIG, config);
startActivityForResult(intent, REQUEST_CODE_SCAN);

the value passing error in the above two lines of code, but I"m not sure. I added try-catch, to the button trigger method but still couldn"t catch the error message.

< H2 > other information < / H2 >

this code is fine for me to use on the first-level page, and a personal test is available. The page on which the
error is reported is a secondary page. When the first-level page jumps to the second-level page, it transmits some information through Intent, which is accepted in the second-level page as follows:

orderId = getArguments().getString("orderId");
getNeedDistributeTableDataBeanList = (List<GetNeedDistributeTable.DataBean>) getArguments().getSerializable("getNeedDistributeTableDataBeanList");

so open the QR code scan page in the second-level page, and the QR code scan page is equivalent to a third-level page.
I don"t know if this other information is useful, so just write it down for the time being.
