Admob ad comes up less then 1/2 the time while in test mode using new admob sdk

I just added a new site on Admod and it sems like they are using a new sdk, where the old one was admod-sdk-android and the new one is GoogleAdMobsdk. I followed googles example code, except I set the testing flag to true. Well it came up at first, all excited that it worked, but when I ran it again, it did not come up. It seems like the ad comes up less then half the time. I know this would be ok if it was not in testing mod. Should the ad allwys come up if the testing flag is true? code

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);


    View mCall = findViewById(R.id.call);
    mCall.setOnClickListener(this);

    View mAbout = findViewById(R.id.about);
    mAbout.setOnClickListener(this);

    View mWhatWeDo = findViewById(R.id.whatwedo);
    mWhatWeDo.setOnClickListener(this);

    View mEmail = findViewById(R.id.email);
    mEmail.setOnClickListener(this);

   View mMap = findViewById(R.id.map);
    mMap.setOnClickListener(this);

    // Create the adView
    // Create the adView
    AdView adv = new AdView(this, AdSize.BANNER, "a14d84be1abee56");

    // Lo开发者_C百科okup your LinearLayout assuming it’s been given
    // the attribute android:id="@+id/mainLayout"
    LinearLayout layout = (LinearLayout)findViewById(R.id.mainLayout);

    // Add the adView to it
    layout.addView(adv);
    // Initiate a generic request to load it with an ad
    AdRequest t=new AdRequest();
    t.setTesting(true);
    adv.loadAd(t);   

}

I faced the same issue as well. The new SDK isn't behaving in the same way the old one was in this regards. I suggest you remove the testing mode and try seeing in the admob reporting page whether you are able to see page requests for your app there..
