android - 加载启动画面后如何显示插页式广告？

Question

我需要帮助，我想在初始屏幕加载后显示插页式广告，但我的代码有错误。

这是我的代码:

public class SplashScreenActivity extends AppCompatActivity {

    InterstitialAd mInterstitialAd;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash_screen);

        // FIREBASE INTERSTICIAL
        mInterstitialAd = new InterstitialAd(this);
        mInterstitialAd.setAdUnitId("ca-app-pub-2565065222479596/3931476543");

        mInterstitialAd.setAdListener(new AdListener() {
            @Override
            public void onAdClosed() {
                requestNewInterstitial();
            }
        });

        requestNewInterstitial();

        Toast.makeText(this,"* Necessário Acesso a Internet *",Toast.LENGTH_LONG).show();

        Thread timerThread = new Thread() {
            public void run() {
                try {
                    sleep(5000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                } finally {

                    if (mInterstitialAd.isLoaded()) {
                        mInterstitialAd.show();
                        Intent intent = new Intent(SplashScreenActivity.this, MainActivity.class);
                        startActivity(intent);
                    }
                    else
                    {
                        Intent intent = new Intent(SplashScreenActivity.this, MainActivity.class);
                    }
                }

            }
        };
        timerThread.start();

    }

    // FIREBASE INTERSTICIAL
    private void requestNewInterstitial() {
        AdRequest adRequest = new AdRequest.Builder()
                .addTestDevice("SEE_YOUR_LOGCAT_TO_GET_YOUR_DEVICE_ID")
                .build();

        mInterstitialAd.loadAd(adRequest);
    }

}

调试后得到以下信息:

即使在调试之后我也无法理解错误的原因。

我只想在启动画面之后或打开主 Activity 时显示插页式广告。

非常感谢!

问题就在这里java.lang.IllegalStateException: isLoaded must be called on the main UI thread.

所以可能必须这样做

 runOnUiThread(new Runnable() {
    @Override public void run() {
        if (mInterstitialAd.isLoaded()) {
          mInterstitialAd.show();
     }
    }
});

可能你必须使用 Activity 引用来调用它，这取决于你从哪里调用

 mYourActivity.runOnUiThread(new Runnable() {
    @Override public void run() {
        if (mInterstitialAd.isLoaded()) {
          mInterstitialAd.show();
     }
    }
});
