如何使用指定浏览器打开网页

就是查看一下本机上可用的浏览器，因为之前做过检测语音识别程序时需要检测Google 语音命令，这里简单的修改了一下就可以查看了。
具体代码如下：

package com.google.code.cakedroid.demo;

import java.util.List;
import com.google.code.cakedroid.R;
import android.app.Activity;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.content.pm.ResolveInfo;
import android.net.Uri;
import android.os.Bundle;

public class BrowserDemo extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// get the view web intent
Intent intent = this.getViewWebIntent();
this.printInterestedActivitiesByIntent(intent);
// set the className to use the specific browser to open the webpage.
intent.setClassName("com.tencent.mtt", "com.tencent.mtt.MainActivity");
startActivity(intent);
}

/*

*get the desired view web intent
*/
private Intent getViewWebIntent() {
Intent viewWebIntent = new Intent(Intent.ACTION_VIEW);
Uri uri = Uri.parse("http://www.2cto.com");
viewWebIntent.setData(uri);
return viewWebIntent;
}

/*

* print the activities that are interested about the intent

*/
private void printInterestedActivitiesByIntent(Intent intent) {
PackageManager pm = this.getPackageManager();
List<ResolveInfo> activities = pm.queryIntentActivities(intent, 0);
if (null != activities) {
for (int i = 0; i < activities.size(); i++) {
ResolveInfo info = activities.get(i);
System.out.println(info.activityInfo.name);
}
} else {
System.out.println("no interested activities");
}
}
}

输出结果为：
12-17 05:02:30.096: I/System.out(217): com.android.browser.BrowserActivity
12-17 05:02:30.096: I/System.out(217): com.tencent.mtt.MainActivity
12-17 05:02:30.096: I/System.out(217): cn.dolphin.browser.BrowserActivity
