ADMOB-java.lang.IllegalStateException：isLoaded必须在主UI线程上调用 [英] ADMOB-java.lang.IllegalStateException: isLoaded must be called on the main UI thread

问题描述

我是android的新手，其我的AndroidLauncherjava文件用于内部代码

I am newbie to android,its my AndroidLauncherjava file for intersial code

       @Override public void onCreate (Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);


        RelativeLayout layout = new RelativeLayout(this);
        AndroidApplicationConfiguration config = new AndroidApplicationConfiguration();


        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
        getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);

        // Create the libgdx View
        View gameView = initializeForView(new MyGdxGame(this),config);


        AdView adView = new AdView(this);
        adView.setAdUnitId("ca-app-pub-6916351754834612/9855033027");
        adView.setAdSize(AdSize.BANNER);
        adView.loadAd(new AdRequest.Builder()
        .build()); 

        layout.addView(gameView);

        // Add the AdMob view
        RelativeLayout.LayoutParams adParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
        adParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, RelativeLayout.TRUE);
        adParams.addRule(RelativeLayout.CENTER_HORIZONTAL, RelativeLayout.TRUE);
        adView.setLayoutParams(adParams);
        adView.setBackgroundColor(Color.BLACK);

        layout.addView(adView, adParams);


       iAd = new InterstitialAd(this);
        iAd.setAdUnitId(AD_UNIT_ID);
        loadInterstitial();
        iAd.setAdListener(new AdListener() {
            @Override
            public void onAdLoaded() {
                }

            @Override
            public void onAdFailedToLoad(int errorCode) {

            }
        });
        setContentView(layout);
       }

    public void loadInterstitial() {
        /*AdRequest adRequest = new AdRequest.Builder()
        .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
        .addTestDevice("0FD328B10106BD9B2BE832163D43D085")
        .build();*/
        AdRequest adRequest = new AdRequest.Builder().build();
        iAd.loadAd(adRequest);

        //iAd.loadAd(adRequest);
    }

    public void showInterstitial() {
        if (iAd.isLoaded()) {
            iAd.show();
        } else {
            //Log.d(TAG, "Interstitial ad is not loaded yet");
        }
    }

这是我的插页式广告代码；我得到 java.lang.IllegalStateException：isLoaded必须在主UI线程上调用。在此检查了几种解决方案，无法解决。我知道iAd没有加载。有人可以帮我吗，我哪里出错了。预先谢谢

Its my code for interstitial ads;I getting java.lang.IllegalStateException: isLoaded must be called on the main UI thread .Checked few solution here,couldn't fixed .I got to know iAd is not loading.Can anyone help me, where i went wrong. Thank you in advance

推荐答案

您没有显示 showInterstitial（）正在被调用，其中包含对 isLoaded 的调用！

请检查堆栈跟踪以获取更多线索。

You didn't show where showInterstitial() is being called which contains the call to isLoaded!
Please check your stack trace for more clues.

我想说的是，您是从事件侦听器或其他（Gdx？）背景线程调用 showInterstitial 的。如果是这种情况，您有两个选择：

Blindly I would say that you're calling showInterstitial from an event listener or other (Gdx?) background thread. If that's the case you have two options:

public void showInterstitial() {
    if(Looper.myLooper() != Looper.getMainLooper()) {
        runOnUiThread(new Runnable() {
            @Override public void run() {
                doShowInterstitial();
            }
        });
    } else {
        doShowInterstitial();
    }
}
private void doShowInterstitial() {
    if (iAd.isLoaded()) {
        iAd.show();
    } else {
        //Log.d(TAG, "Interstitial ad is not loaded yet");
    }
}

使调用代码更智能

Make calling code smarter

void myMethodCallingShowInterstitial() {
    ... doing my other background stuff ...
    // replace showInterstitial(); with below:
    activityReference.runOnUiThread(new Runnable() {
        @Override public void run() {
            activityReference.showInterstitial();
        }
    });
    ... doing my other background stuff ...
}

在在上述两种情况下，您在 runOnUiThread 之后所做的任何操作都不能依赖于展示插页式广告！如果您不小心实现了两者，那么这不是问题，因为防呆方法不会将其再次发布到UI。

In both of the above cases anything you do after runOnUiThread CANNOT rely on interstitial being shown! If you accidentally implement both it's not a problem because the fool-proof method won't post it again to the UI.

作为的替代方法runOnUiThread 可以使用 Handler ，有关更多信息，请参见这方面的官方文档。

As an alternative to runOnUiThread you can use a Handler, for more see the official documentation on this.
