Sending data from a child activity onActivityResult() to parent activity onActivityResult()

Question

I have an App with 2 Activities. Activity A (parent) starts Activity B (child) by calling:

startActivityForResult(intentB,B_Request);

Activity B is a barcode scanner. (I use this library: com.journeyapps:zxing-android-embedded:3.2.0@aar). In this activity I have to override the onActivityResult() method in order to get the scanned code. After that I want to send the data stored in 'code' back to the parent (Activity A) onActivityResult(). I did this like this:

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
        String code = null;

        if(result != null){
            if(result.getContents() == null){
                return;
            }
            else {
                code = result.getContents();
            }
        }
        else {
            super.onActivityResult(requestCode, resultCode, data);
        }

        Intent intent = new Intent(getApplicationContext(),A.class);
        intent.putExtra("scannedCode", code);
        setResult(RESULT_OK, intent);
        finish();
}

The parent onActivityResult() looks like this:

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if(requestCode == CAMERA_REQUEST){
            if(resultCode == RESULT_OK){

                String scannedCode = data.getStringExtra("scannedCode");
                toastMessage("Scanned code: " + scannedCode);
            }
        }
    }

I get the following exception and instead of seeing Activity A, I'm redirected to the Activitie's A parent.

p.s. It's not enough for me to get the code in Activity B, I need the code back in Activity A.

Can you please tell me what am I doing wrong here?

Thank you!

Answer 1

just put new intent() instead of

new Intent(getApplicationContext(),A.class)

in your child activity
