        setContentView(R.layout.test_activity);
        mInterstitialAd = new InterstitialAd(this);
        mInterstitialAd.setAdUnitId("ca-app-pub-9547225037870226/6863551510");
        adRequest = new AdRequest.Builder()
                .build();
        mInterstitialAd.loadAd(adRequest);
        mInterstitialAd.setAdListener(new AdListener() {
            @Override
            public void onAdFailedToLoad(int i) {
                super.onAdFailedToLoad(i);

            }

            public void onAdLoaded() {
                Toast.makeText(TestActivity.this, "ad loaded", Toast.LENGTH_SHORT).show();

                showInterstitial();

                super.onAdImpression();
                Toast.makeText(TestActivity.this, "ad impression", Toast.LENGTH_SHORT).show();

            }

        });
    }
    private void showInterstitial() {
        if (mInterstitialAd.isLoaded()) {
            mInterstitialAd.show();

onAdClicked is not intended for use with interstitial ads, and isn't invoked for them. From the documentation:

Called when a click is recorded for an ad. At the current time, this method is only used with native ads originating from Google in one of the system-defined formats (App Install or Content).

If you'd like to know when the user has clicked on an interstitial, though, you can use the onAdLeftApplication method instead. Clickthroughs will result in focus leaving the application, so it's a reliable way to know.
