我是Android编码新手。我正在尝试一个简单的代码，例如点击按钮，如果点击它会打开Google。如果我运行我的代码，如果我单击该按钮，浏览器将打开，并在一段时间后显示UNFORTUNATELY BROWSER STOPPED。请帮我。提前谢谢。
package com.example.single_button_google;
import android.net.Uri;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
public class MainActivity extends Activity {
Button b1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
b1= (Button) findViewById(R.id.button1);
b1.setOnClickListener(click);
}
View.OnClickListener click = new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse("https://www.google.co.in/"));
startActivity(intent);
}
};
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}

似乎是与模拟器和SD卡相关的问题。尝试更改模拟器上的某些配置或在真实设备上尝试应用。
