java – AdMob必须在主UI线程上调用插页式广告和错误isLoaded

用户William建议我更改我的代码以显示插页式广告

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
    //setDebugMode(true);
    initialiseAccelerometer();

    interstitial = new InterstitialAd(this);
    interstitial.setAdUnitId(getResources().getString(R.string.InterstitialAd_unit_id));

    interstitial.setAdListener(new AdListener() {
        public void onAdClosed() {
            // Create another ad request.
            final AdRequest adRequest = new AdRequest.Builder()
                .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
                .build();
            interstitial.loadAd(adRequest);
        }
    });
    // Create ad request.
    final AdRequest adRequest = new AdRequest.Builder()
            .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
            .build();
    interstitial.loadAd(adRequest);
}

并显示广告：

public synchronized void GameOver() {
    if (lives_left > 0) {
        //success! - game passed - save score
        scoreManager.save_localscore_simple(score_times[currentLevel],"" + currentLevel,false);

        if (Level_Buttons.length >= currentLevel + 1)
            scoreManager.save_localscore_simple(unlocked,"unlock" + (currentLevel + 1));

        if (sound_success != 0 && !sound_muted)
            sp.play(sound_success,1,1);

        //open interstitial ad
        if (interstitial.isLoaded()) {
            interstitial.show();
        }


    } else {
        //game not passed
        if (sound_gameover != 0 && !sound_muted)
            sp.play(sound_gameover,1);
    }


    //open interstitial ad
    if (interstitial.isLoaded()) {
        interstitial.show();
    }

    StopMusic();
    state = GAMEOVER;

}

在游戏的每个游戏中我都会收到此错误：

这有什么不对？请尽可能简单地解释我,因为我之前没有任何编程知识的新手:)谢谢！

解决方法

这可能不是完整的答案,但很难说出正确的答案,因为上面的代码并不清楚.你没有显示你在哪里使用GameOver(),但我认为你在错误的地方调用它,我认为你在任何后台线程中调用它,因为在GameOver中你调用interstitial.isLoaded()导致你的问题.就像stacktrace所说的那样,在主ui线程中调用它.例如,在您的GameOver()中调用它：

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

可能你必须用活动参考调用它,它取决于你在哪里调用GameOver()：

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