java - WebView 可能不支持在 StartApp 的其他线程上使用

Question

我正在尝试集成到我的游戏启动应用程序中，从一项 Activity 更改为另一项退出宣传和广告，广告可以正确显示我，但是当点击广告时，会出现以下错误。

java.lang.RuntimeException: java.lang.Throwable: Warning: A WebView method was called         on thread 'Thread-1082'. All WebView methods must be called on the UI thread. Future versions of WebView may not support use on other threads.
at android.webkit.WebView.checkThread(WebView.java:1927)
at android.webkit.WebView.destroy(WebView.java:641)
at com.startapp.android.publish.AppWallActivity$6.run(Unknown Source)

at android.webkit.WebView.checkThread(WebView.java:1918)

有谁知道为什么会这样吗？

这是我用来打开它的代码:

startAppAd.showAd(new AdDisplayListener() 
            {

                public void adDisplayed(Ad arg0) {
                    // TODO Auto-generated method stub

                }

                public void adHidden(Ad arg0) {
                    Intent i = new Intent(getApplicationContext(), SeleccionarLigaActivity.class);
                    i.putExtra("PrimeraVez", primeraVez);   
                    startActivity(i);
                }

            });

我也尝试过这个:

MainActivity.this.runOnUiThread(new Runnable() {
                public void run() {
                    startAppAd.showAd();
                    startAppAd.loadAd();
                }
            });

现在在 2.0.5 中出现此错误:

问候和感谢。

不要在新的Thread中使用，WebView应该在UI Thread中使用~

或者你可以看看答案~ WebView Methods is not called in android
