Java app"；不幸的是，我停了下来；当触摸间隙广告时

我使用的是cocos2d-x3.2，我想在用户触摸屏幕时显示间隙广告。 但当我触摸屏幕时，我收到了“不幸停止”的信息。 这是我的密码：

爪哇：

C++:

我在logcat中发现了这个错误：

A/libc(6628): Fatal signal 11 (SIGSEGV) at 0x00020004 (code=1), thread 6643 (Thread-553)

---

有人能帮忙吗？（对不起，英文：）

你必须先加载广告，然后再显示：

private boolean adIsLoaded = false;

protected void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);

    final String ADMOB_ID = "ca-app-pub-0000000000000000/0000000000";
    interstitial = new InterstitialAd(this);
    interstitial.setAdUnitId(ADMOB_ID);

    AdRequest.Builder builder = new AdRequest.Builder();
    AdRequest adRequest = new AdRequest.Builder().addTestDevice("3A34952B128D8DC19CCB75CA752ED31B").build();
    interstitial.setAdListener(new AdListener() {
        @Override
        public void onAdLoaded() {
            adIsLoaded=true;
        }
    });

    interstitial.loadAd(adRequest);

}

public void showad() { 
    if (adIsLoaded)
            interstitial.show();
    }
}

<>因为它是代码> SigSeGvHelloWorld:：show（），在每行之间打印日志，以找出哪一行导致了崩溃。这听起来很愚蠢，但很有效

---

顺便说一句，您必须分析崩溃点附近的整个日志，而不是崩溃时的行。

尝试使用getStaticMethodInfo（）和CallStaticVoidMethod（）。还将showad（）设为静态函数

这对我很有效。但是，当我将getMethodInfo（）和CallVoidMethod（）与非静态java函数一起使用时，代码既不工作也不会崩溃。它根本不起任何作用

---

还没弄明白原因

我是这样修复的：

    private static AppActivity _appActiviy;
       @Override
    protected void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);

    final String ADMOB_ID = "ca-app-pub-0000000000000000/0000000000";
    interstitial = new InterstitialAd(this);
    interstitial.setAdUnitId(ADMOB_ID);

    AdRequest.Builder builder = new AdRequest.Builder();
    AdRequest adRequest = new AdRequest.Builder().addTestDevice("3A34952B128D8DC19CCB75CA752ED31B").build();

    interstitial.loadAd(adRequest);
    }

    public static void showAd(){
    _appActiviy.runOnUiThread(new Runnable()
    {

    @Override
     public void run(){ 
         if (_appActiviy.interstitial.isLoaded())
            {_appActiviy.interstitial.show();}

};
});}

我的应用程序仍然崩溃。

    super.onCreate(savedInstanceState);

    final String ADMOB_ID = "ca-app-pub-0000000000000000/0000000000";
    interstitial = new InterstitialAd(this);
    interstitial.setAdUnitId(ADMOB_ID);

    AdRequest.Builder builder = new AdRequest.Builder();
    AdRequest adRequest = new AdRequest.Builder().addTestDevice("3A34952B128D8DC19CCB75CA752ED31B").build();
    interstitial.setAdListener(new AdListener() {
        @Override
        public void onAdLoaded() {
            adIsLoaded=true;
        }
    });

    interstitial.loadAd(adRequest);

}

    if (adIsLoaded)
            interstitial.show();
    }
