我正在制作博客URL的Webview应用程序。我对其进行了测试，然后生成了一个签名的apk。到这里为止一切正常，然后我注意到当我旋转屏幕时会重新加载。我去搜索并解决了问题，但是：
-该应用程序停留在初始屏幕上。 {我之后添加了进度条。 } -该应用程序的进度栏不起作用。
-该应用程序在旋转到横向时会在初始屏幕后面显示广告横幅
我处理过布局部分，根据我的知识，我查看了未发现任何错误的代码。现在，我对下一步的工作一无所知。
我知道我们不应该粘贴整个文件，即使那样，
主要活动Java
int[] array1 = new int[] { 1,2,3,4,5,6,7,8,9,10 };
for (int i = 0; i < array1.Length; i+=2)
{
try
{
Console.WriteLine(array1[i] + " " + array1[i+1]);
}
catch (System.IndexOutOfRangeException)
{
System.Console.WriteLine(array1[i]);
Console.ReadLine();
}
}
