int value passed with intents doesn't change second time despite onNewIntent()

I pass an integer value (guide) to the next class(activity) like this: in different activities.. first:

                public void onClick(View v) {

                Intent intent002a = new Intent(getApplicationContext(), GameOver002a.class);
                intent002a.putExtra("guide", 11001001);
                startActivity(intent002a);

            }

second:

                public void onClick(View v) {

                Intent intent003a = new Intent(getApplicationContext(), GameOver002a.class);
                intent003a.putExtra("guide", 11002001);
                startActivity(intent003a);

            }

and so on..

Then I receive the intent:

 @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
    setContentView(R.layout.activity_game_over002a);

    onNewIntent(getIntent());
}
@Override
protected void onStart() {
super.onStart();
    UnityAds.changeActivity(this);

    UnityAds.init( this, "*******", this);

    UnityAds.setDebugMode(true);
    UnityAds.setTestMode(true);


    TextView neinTextView = (TextView) findViewById(R.id.nein_textview002a);
    if (neinTextView != null) {
        neinTextView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                Intent intent = new Intent(getApplicationContext(), Startbildschirm.class);
                startActivity(intent);

            }


        });
    }


    TextView jatextview = (TextView) findViewById(R.id.ja_textview002a);
    if (jatextview != null) {
        jatextview.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                new AlertDialog.Builder(GameOver002a.this)

                        .setMessage("Watch a short ad to continue at the last checkpoint?")
                        .setNegativeButton(android.R.string.no, null)
                        .setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface arg0, int arg1) {
                                if (UnityAds.setZone("rewardedVideo") && UnityAds.canShow()) {
                                    UnityAds.show();
                                }}
                        }).create().show();



            }

        });
    }

}


@Override
public void onBackPressed() {
    new AlertDialog.Builder(this)

            .setMessage(R.string.zurück_zum_menü_frage)
            .setNegativeButton(android.R.string.no, null)
            .setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface arg0, int arg1) {
                    Intent intent = new Intent(getApplicationContext(), Startbildschirm.class);
                    startActivity(intent);
                }
            }).create().show();
}

@Override
public void onHide() {

}

@Override
public void onShow() {

}

@Override
public void onVideoStarted() {

}

@Override
public void onVideoCompleted(String s, boolean b) {
    levelAuswahl();
}

@Override
public void onFetchCompleted() {
}

@Override
public void onFetchFailed() {
    TextView jatextview = (TextView) findViewById(R.id.ja_textview002a);
    if (jatextview != null) {
        jatextview.setText(R.string.videoladen_fail);
        jatextview.setClickable(false);
    }

}
@Override
public void onResume()
{
    super.onResume();
    UnityAds.changeActivity(this);

    onNewIntent(getIntent());
}

public void levelAuswahl() {
    int guide;
    guide = getIntent().getIntExtra("guide",0);
    if (guide == 11001001) {
        Intent intent = new Intent(getApplicationContext(), Story001a.class);
        startActivity(intent);
    }else if (guide == 11002001) {
        Intent intent = new Intent(getApplicationContext(), Story002b.class);
        startActivity(intent);
    }else if (guide == 11007001) {
        Intent intent = new Intent(getApplicationContext(), Story004a.class);
        startActivity(intent);
    } else {
        Intent intent = new Intent(getApplicationContext(), Startbildschirm.class);
        startActivity(intent);
    }

}
@Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);
    // getIntent() should always return the most recent
    setIntent(intent);
}

}

to choose the right activity.. EVERY PART OF THE STORY HAS HIS OWN ACTIVITY

following scenario: I start the app and fail at the Story002a activity .. then I pass an integer value (guide) with an intent .. After watching an ad succesful the method levelAuswahl() is called (level chooser). it receives the intent and takes the right if clause and I start again at Story001.. THIS PART WORKS CORRECT BUT.. if I fail at Story003a the value guide is passed with an intent exact as in Story002a..but this time in the the same activitie opens although I use onNewIntent()..

what do I need to change? Any ideas?

Thanks in advance!

here is the manisfest:

</application>

Instead of using

android:launchMode="singleTask" //or singleTop

is used

intent.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);

and everything works fine

use onNewIntent() like this to get your new intent

@Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
// getIntent() should always return the most recent
setIntent(intent);
}
