Loading multiple AdMob videos

Question

For demonstration purposes, the app has one activity that simply offers this:

You click a button, view a rewarded video, and you are rewarded with whatever.

The Problem

How can I load the videos? From what I have seen you can only call mAd.loadAd() once. There are 3 videos, each with their own AD UNIT ID. Each ad unit can have its own listener, but only one video loads so it doesn't matter...

When trying to load multiple videos

For example:

mAd1.loadAd("AD_UNIT_1", new AdRequest.Builder().build());
mAd2.loadAd("AD_UNIT_2", new AdRequest.Builder().build());
mAd3.loadAd("AD_UNIT_3", new AdRequest.Builder().build());

results in only the last video being loaded and this in log:

W/Ads: Loading already in progress, saving this object for future refreshes.

onCreate()

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mAd1 = MobileAds.getRewardedVideoAdInstance(this);
    mAd2 = MobileAds.getRewardedVideoAdInstance(this);
    mAd3 = MobileAds.getRewardedVideoAdInstance(this);

    listeners...

    mAd1.loadAd() etc
}

Thank you for your help

Edit: It's clear I am thinking about this problem wrong. I have 5+ ad zones that each will play a rewarded video and give a different reward (for example, one gives coins, one gives a level up, and so on..). There is no reason to load 5 videos. I should load one in onCreate(), so it's ready when needed, then load it again after the item is rewarded so it's ready for next time.

So the question remains, if there is just the one video, and thus one ad zone, being loaded onCreate() then how can I track what reward to give?

Here's a simple solution...

MainActivity.java

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mAd = MobileAds.getRewardedVideoAdInstance(this);

    mAd.setRewardedVideoAdListener(new RewardedVideoAdListener() {

        @Override
        public void onRewarded(RewardItem rewardItem) {
            switch(Constants.currentAd) {
                case("REWARD1"):
                    //do something
                    Constants.currentAd = "";
                    break;

                case("REWARD2"):
                    //do something
                    Constants.currentAd = "";
                    break;

                case("REWARD3"):
                    //do something
                    Constants.currentAd = "";
                    break;
            }
        }
    });

   mAd.loadAd("REWARDED_VIDEO_UNIT_ID", new AdRequest.Builder().build());
}

public void showRewardedVideo() {
        if (mAd.isLoaded()) {
            mAd.show();
        }
    }

Constants.java

public class Constants {
    public static String currentAd = "";
}

Showing the ad after button click

rewardButton1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Constants.currentAd = "REWARD1";
                dismiss();
                ((MainActivity) getActivity()).showRewardedVideo();
            }
        });

REWARDED_VIDEO_UNIT_ID is one ad unit for rewarded video in AdMob...remove the rest. No need for other units, you can track whatever you like in the listener.

it makes no sense if there is only one unit id for all videos. Could you please prove it? — YTerle, Nov 03 '16 at 13:15

Other simple soluction...

AbstractRewardVideo.java

public abstract class AbstractRewardVideo {
    private RewardedVideoAd mAd;

    }

    public Activity getActivity(){

        public void onRewardedVideoAdFailedToLoad(int i) {}
    }

}

MainActivity.java

public class MainActivity extends AppCompatActivity{
    Reward1 reward1;
    Reward2 reward2;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        reward1 = new Reward1(this);
        reward2 = new Reward1(this);
        ...
        reward1.showVideo();
        ...
        reward2.showVideo();

    MobileAds.initialize ( this, "ca-app-pub-4761500786576152~8215465788" );

    RewardedVideoAd mAd = MobileAds.getRewardedVideoAdInstance(this);
    mAd.setRewardedVideoAdListener(Video_Ad.this);

}

@Override
public void onRewardedVideoAdLoaded() {

}

@Override
public void onRewardedVideoAdOpened() {

}

@Override
public void onRewardedVideoStarted() {

}

@Override
public void onRewardedVideoAdClosed() {

@Override

public void onRewardedVideoAdLeftApplication() {

}

@Override
