Android text view not found during execution time

Issue

I have a text view that has to be updated on execution time. This text view is defined by the following xml:

<TextView
android:id="@+id/agi_val"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView" />

In the activity code, i acces to this (and other TextViews) like this:

private TextView AGI;
///< Some stuff

 protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_abf__char_gen__basic_info);

        abfToolsSaveData = (ABFToolsSaveData) getIntent().getParcelableExtra("SaveDataClass");

        this.AGI = (TextView) findViewById(R.id.agi_val);
        ///< Some stuff

        if (abfToolsSaveData != null) {
            this.chargeData(true);
        } else {
            Log.d("INFO", "abfToolsSaveData is null");
        }
    }

And then, in chargeData(boolean):

public void chargeData(boolean firstTime){
        if(firstTime){
            MainCharacteristics mc = abfToolsSaveData.getCharacter().getMainCharacteristics(); ///< We get the main characteristics, auto-generated the first time

            /**
             * Set the Text Views with the default value
             */
            if(AGI != null){    ///< I've done this to check if the text view is null or not
                Log.d("INFO", String.valueOf(AGI));
                AGI.setText(mc.getAGI());
            }
            else
                Log.d("INFO","AGI IS NULL");
            ///< Some stuff
        }
    }

The thing is that the "agi_val" textview is being found, but the AGI textview of the activity, that i had saved before, it can't acces the resource "agi_val" whose linked. The error log is the following:

///< This first line shows the value of the "agi_val" ID. As you can see, it's not null.

Someone knows what the hell is happening? I've been two days trying to solve this and I don't know how (i've searched on internet, but i can't find something similar).

If someone asks for the R class ID, its the same as show on the first line in the log.

Solution

Well, i've asked this same answer in "Stack Overflow en Español" and i get the answer.

The thing is that the mc.getAGI() is returning an int, so is using the override of setText(int resourceId), that finds the resource R.string that has the id value.
