How to apply Polyglot Detector function to dataframe

Assuming I have a column called df.Text which contains text (more that 1 sentence) and I want to use polyglot Detector to detect the language and store the value in a new column df['Text-Lang'] how do I ensure I also capture the other details like code and confidence

testEng ="This is English"
lang = Detector(testEng)
print(lang.language)

returns

name: English code: en confidence: 94.0 read bytes: 1920

but

df['Text-Lang','Text-LangConfidence']= df.Text.apply(Detector)

ends with

AttributeError: 'float' object has no attribute 'encode' and Detector is not able to detect the language reliably.

Am I applying the Detector function incorrectly or storing the output incorrectly or something else?

java.lang.IllegalStateException: Fragment not attached to a context

I have a tablayout with a viewpager in my MainActivity.

My PagerAdapter looks like this:

public class MainActivityPagerAdapter extends PagerAdapter {

    public MainActivityPagerAdapter(FragmentManager fm, int numOfTabs) {
        super(fm, numOfTabs);
    }

    @Override
    public Fragment getItem(int position) {

        switch (position) {
            case 0:
                return new StoresFragment();
            case 1:
                return new OrdersFragment();
            default:
                return null;
        }
    }
}

I am coming back from another activity like this:

Intent intent = new Intent(context, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
finish(); //finishAffinity();

But then I get an java.lang.IllegalStateException in one of my Fragments in the viewpager of the MainActivity.

I read many related questions and tried to solve this. It is said, that this happens when one keeps references to Fragments outside of the PagerAdapter. But I am not doing this, as you can see in my code.

Does anyone know what I am doing wrong?

Edit: Interesting is, that the view has defenitely loaded when the error occurs. Because the error occurs about 10-15 seconds later after the fragment is shown again. I this in my orderFragment, where the error occurs:

orders = new QueryResult<UserOrder>(UserOrder.class) {
            @Override
            public void results(List<UserOrder> results) { 
orderLoadingMessage.setBackgroundColor(getResources().getColor(R.color.green)); 
    }
}

I do this in onCreateView and this result comes about 10-15 seconds after the view loaded.

__soapCall is returning nothing

I've got the following function:

public function query($sql)
{
    $query = array(
    "queryString"=>$sql
    );
    $queryWrapper = array(
    "query"=>$query
    );

    try {
        $result = $this->_client->__soapCall("query", $queryWrapper, null, $this->_header);
    } catch (SoapFault $e) {
      $this->_client->__getLastResponse();
    }
    return $result;
}

The problem is that I can use var_dump('anything');exit; before the __soapCall(), and I see 'anything'. But if I var_dump('stuff');exit; AFTER the __soapCall(), I get just a blank page. I var_dump('something');exit; in the catch, but I don't see that. It's still just a blank page. My question is, what could be causing this? I would think that if the table in my query didn't exist, or something was wrong with my query at all, I'd get some sort of error. But I'm getting absolutely squat all.
