检测手机是否有浏览器：

方法一：

public boolean isExitBrowser(Context context,String url){

Uri uri = Uri.parse(url);

        Intent intent =new Intent(Intent.ACTION_VIEW,uri);

        intent.setComponent(null);

        List rList = context.getPackageManager().

queryIntentActivities(intent,PackageManager.MATCH_DEFAULT_ONLY|

PackageManager.GET_RESOLVED_FILTER);

        final int browsersize = rList.size();

        if(browsersize>0){

//          for(int i=0;i

//            Log.i(TAG,"i= " + rList.get(i).activityInfo.name);

            return true;

        }

return false;

    }

方法二：

@SuppressLint("WrongConstant")

private boolean hasBrowser(Context context){

PackageManager pm = context.getPackageManager();

    Intent intent =new Intent(Intent.ACTION_VIEW);

    intent.addCategory(Intent.CATEGORY_BROWSABLE);

    intent.setData(Uri.parse("http://"));

    List list = pm.queryIntentActivities(intent, PackageManager.GET_INTENT_FILTERS);

    final int size = (list ==null) ?0 : list.size();

    return size >0;
