How to specify adUnitId programmatically for AdMob?

I'm trying to set adUnitId programmatically to ads from the new Google Play services (old AdMob).

I have this in XML (used in an <include>):

<com.google.android.gms.ads.AdView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ads="http://schemas.android.com/apk/res-auto"
    android:id="@+id/adView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    ads:adSize="BANNER"/>

and this in onCreate():

AdView mAdview = (AdView)findViewById(R.id.adView);
    mAdview.setAdUnitId(((App)getApplication()).getAdmobKey());

    mAdview.setAdListener(new AdListener() {
        @Override
        public void onAdLoaded() {
            super.onAdLoaded();
            findViewById(R.id.adView).setVisibility(View.VISIBLE);
        }
    });

    AdRequest adRequest = new AdRequest.Builder()
            .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
            .build();
    mAdview.loadAd(adRequest);

And I get:

The ad size and ad unit ID must be set before loadAd is called.

So the second option was to make the ad programmatically.

The new XML:

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_height="wrap_content"
    android:layout_width="match_parent"
    android:id="@+id/adView"
    />

The new code:

AdView mAdview = new AdView(this);
...
((LinearLayout)findViewById(R.id.adView)).addView(mAdview);
mAdview.loadAd(adRequest);

But I get the same error.

I tried also to inherit from com.google.android.gms.ads.AdView to make a custom view, but it's final.

Any suggestion?

The method loadAd() checks if (mAdView.getAdSize() == null || mAdView.getAdUnitId() == null) when loadAd happens.

Try logging the boolean output of (mAdView.getAdSize() == null || mAdView.getAdUnitId() == null) before calling loadAd to determine its state:

    mAdView = new AdView(this);
    mAdView.setAdSize(AdSize.BANNER);
    mAdView.setAdUnitId(AD_UNIT_ID);
    AdRequest adRequest = new AdRequest.Builder()
        .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
        .build();
    if(mAdView.getAdSize() != null || mAdView.getAdUnitId() != null)
    mAdView.loadAd(adRequest);
   // else Log state of adsize/adunit
((LinearLayout)findViewById(R.id.adView)).addView(mAdview);
