Java 删除应用程序已停止？

我正在尝试构建一个应用程序，当应用程序启动时，它会在android浏览器中打开一个网页。它工作正常，除非在网页开始加载后，我收到了这个不幸的应用程序已停止消息，但页面继续加载，我可以在消息上单击“确定”，它消失，浏览器保持打开页面，我可以按预期使用它。我怎样才能让那个消息不再出现

这是日志

主要活动

package com.sugarray.nasamobile;

import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;

public class MainActivity extends Activity {
    /** Called when the activity is first created. */
   @Override
    protected void onCreate(Bundle savedInstanceState) {
        Uri uriUrl = Uri.parse("http://mobile.nasa.gov"); 
        Intent launchBrowser = new Intent(Intent.ACTION_VIEW, uriUrl);
        startActivity(launchBrowser);

   }
public void exit(View view){
    System.exit(0);
}


}

只需将此行添加到onCreate的开头：

附言：你应该学会阅读日志。它们确实已经包含了解决方案。

读取堆栈跟踪。它说：

android.app.SuperNotCalledException: Activity  
{com.sugarray.nasamobile/com.sugarray.nasamobile.MainActivity} did not call through to super.onCreate()  

正如FD_uu已经指出的，您忘记调用super.onCreate了。根据经验，大多数Android方法都需要您调用它们的超级方法，尤其是生命周期中的超级方法

注：堆叠痕迹是供人类阅读的，而不是翻译成英语的外来手语。哈哈

你读到错误了吗？你的应用程序的全部目的就是打开一个网页吗？@turbo shhh。。。它打开了Nasa的一些绝密页面xD

android.app.SuperNotCalledException: Activity  
{com.sugarray.nasamobile/com.sugarray.nasamobile.MainActivity} did not call through to super.onCreate()
