Question

我正在尝试构建一个应用程序，在应用程序启动时在Android浏览器中打开网页。它工作正常除了网页开始加载后我得到这个“不幸的应用程序停止”消息但页面继续加载，我可以点击消息上的“确定”，它消失，浏览器保持打开页面我可以按预期使用它。如何才能让该消息停止弹出？

这是logcat

MainActivity

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);
}


}

Answer 1

只需将此行添加到onCreate()的开头：

super.onCreate(savedInstanceState);

PS：您应该学会阅读日志。他们确实已经包含了解决方案。

Answer 2

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()

您忘记拨打super.onCreate()，因为FD_已经指出了。根据经验，大多数Android方法都需要您调用超级方法，尤其是生命周期中的方法。

注意：堆栈痕迹是供人类阅读的，并不是一些音译为英语的外星手语。 LOL
