复制代码 代码如下:
package com.gzz.whyinzi;

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

public class MainActivity extends Activity {
private static final String TAG = "ActivityDemo";

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);


Intent intent = new Intent();
intent.setAction("android.intent.action.VIEW");
Uri content_url = Uri.parse(https://);
intent.setData(content_url);
startActivity(intent);


}

@Override
protected void onResume() {
super.onResume();
Intent intent = new Intent();
intent.setAction("android.intent.action.VIEW");
Uri content_url = Uri.parse("http://play.jb51.net");
intent.setData(content_url);
startActivity(intent);
Log.e(TAG, "start onResume~~~");
}

@Override
protected void onStop() {
super.onStop();
this.finish();
Log.e(TAG, "start onStop~~~");
}
}

onResume()在没有默认浏览器的时候就起作用了,当没有默认浏览器的时候会弹出提示以哪个浏览器打开,如果点击取消就会出现黑色背景,为防止出现黑色背景,onsume()重新调用打开浏览器.

onStop()在选择浏览器后结束进程.
