我的代码实现

对于奖励视频

        rewardedVideo = new StartAppAd(context);
        rewardedVideo.loadAd(StartAppAd.AdMode.REWARDED_VIDEO, new AdEventListener() {

            @Override
            public void onReceiveAd(Ad arg0) {
            }

            @Override
            public void onFailedToReceiveAd(Ad arg0) {
            }
        });
        rewardedVideo.showAd(new AdDisplayListener() {
            @Override
            public void adHidden(Ad ad) {
            }
            @Override
            public void adDisplayed(Ad ad) {
            }
            @Override
            public void adClicked(Ad ad) {
            }
            @Override
            public void adNotDisplayed(Ad ad) {
            }
        });
        rewardedVideo.setVideoListener(new VideoListener() {

            @Override
            public void onVideoCompleted() {
            }
        });

对于非页内广告

        final StartAppAd startAppAdOne = new StartAppAd(context);
        startAppAdOne.loadAd(StartAppAd.AdMode.AUTOMATIC, new AdEventListener() {

            @Override
            public void onReceiveAd(Ad arg0) {
                startAppAdOne.showAd();
            }

            @Override
            public void onFailedToReceiveAd(Ad arg0) {
                Log.e("MainActivity", "Failed to load add: " + arg0.getErrorMessage());
            }
        });
