Changes to AdWords scripts execution logs

Posted: 30 Apr 2014 01:19 PM PDT

As part of our ongoing efforts to improve the performance of AdWords scripts, we are making some changes to the way we provide execution logs for scripts.

Starting May 15, 2014, we will only retain detailed execution logs for scripts that ran during the last 90 days. If you need to retrieve changes made by scripts from an earlier date, you can refer to your account's change history.

If you have any questions about this change, let us know on the forum or on our Google Ads Developers Google+ page.

How to Create a Google Mobile Ads Splash Screen Interstitial on Android

Posted: 30 Apr 2014 12:44 PM PDT

Previously, we showed you how to create a splash screen interstitial on iOS. Today we'll discuss how to trigger an interstitial on an Android app launch.

The cleanest solution is to have an app launch Activity for showing the splash screen image and loading/showing the interstitial. This special splash screen activity should be the activity that launches when the user starts the app. In the splash screen activity's onCreate method, the first task is to make an ImageView and set it as the content view.


@Override
protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  ImageView image = new ImageView(this);
  // Assumes you have a resource with the name kitten.
  image.setImageResource(R.drawable.kitten);
  setContentView(image);

Next, create and load the interstitial ad. Setting an AdListener is needed in order to know when the ad succeeds or fails to load. If the interstitial loads within a reasonable time limit, we'll show it. If it fails, we'll move on to the main activity.


  interstitial = new InterstitialAd(this);
  interstitial.setAdUnitId(AD_UNIT_ID);
  interstitial.setAdListener(new AdListener() {
    @Override
    public void onAdLoaded() {
      if (!interstitialCanceled) {
        waitTimer.cancel();
        interstitial.show();
      }
    }

    @Override
    public void onAdFailedToLoad(int errorCode) {
      startMainActivity();
    }
  });

The "reasonable time limit" mentioned earlier is enforced by creating a timer to stop waiting for the interstitial. If the interstitial doesn't load fast enough (in this case 5 seconds), we skip it and proceed to the main activity.


  waitTimer = new Timer();
  waitTimer.schedule(new TimerTask() {
    @Override
    public void run() {
      interstitialCanceled = true;
      SplashScreenActivity.this.runOnUiThread(new Runnable() {
        @Override
        public void run() {
          startMainActivity();
        }
      });
    }
  }, 5000);
} // end of onCreate implementation.

private void startMainActivity() {
  Intent intent = new Intent(this, MainActivity.class);
  startActivity(intent);
  finish();
}

Handing Early Exits

The code so far assumes that the user will stay in the activity for the duration of the interstitial loading. But what if the user hits the back or home button before the interstitial loads or the timer goes off? The interstitial will actually continue loading and could be shown on top of the home screen! That would be a poor user experience.

We account for this edge case by implementing the onPause and onResume methods from the activity lifecycle. In onPause, we stop the timer and set the interstitialCanceled flag so the interstitial doesn't get immediately shown. In onResume, we show the interstitial if it's ready when the user returns to the app again, otherwise we start the main activity.


@Override
public void onPause() {
  waitTimer.cancel();
  interstitialCanceled = true;
  super.onPause();
}

@Override
public void onResume() {
  super.onResume();
  if (interstitial.isLoaded()) {
    interstitial.show();
  } else if (interstitialCanceled) {
    startMainActivity();
  }
}

If you're wondering why interstitialCanceled is checked again before starting the main application, it's because onResume gets called immediately after onCreate the first time the app is loaded. And on the first app launch, we do want to wait for the interstitial to load.

A complete implementation is available in our googleads-mobile-android-examples repo on GitHub. Give us a shout on the forum if you have any questions about implementing the Google Mobile Ads SDK in your mobile applications. You can also find us on Google+.
