使用BrowserUtil启动外部浏览器访问网页

public class BrowserUtil {


    public static List<ResolveInfo> getBrowserList(Context context){
        PackageManager packageManager = context.getPackageManager();
        Intent intent = new Intent(Intent.ACTION_VIEW);
        intent.setData(Uri.parse("https://www.google.com"));
        List<ResolveInfo> list = packageManager.queryIntentActivities(intent,
                PackageManager.MATCH_ALL);

        if (list == null || list.size() ==0){
            return null;
        }
        ResolveInfo r0 = list.get(0);// The first item is the one that best meets the matching criteria
        Iterator<ResolveInfo> activity_iter = list.iterator();
        while (activity_iter.hasNext()) {
            ResolveInfo resolveInfo = activity_iter.next();
            // Filter out non browsers and non installed browsers
            if (r0.priority != resolveInfo.priority || r0.isDefault != resolveInfo.isDefault || !isAppInstalled(resolveInfo.activityInfo.packageName, context)) {
                list.remove(resolveInfo);
            }
        }
        return list;
    }

    private static boolean isAppInstalled(String packageName, Context context) {
        PackageInfo packageInfo;
        try {
            packageInfo = context.getPackageManager().getPackageInfo(packageName, 0);
        } catch (PackageManager.NameNotFoundException e) {
            packageInfo = null;

        }

            return false;
        } else {
            return true;
        }
    }

    public static void openUrlInBrowser(String uri, Context context){
        List<ResolveInfo> resolveInfoList = getBrowserList(context);
        try {
            Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(replaceToHttps(uri)));
            if (resolveInfoList != null || resolveInfoList.size() != 0){ // The system has browsers， We choose the first browser
                intent.setClassName(resolveInfoList.get(0).activityInfo.packageName, resolveInfoList.get(0).activityInfo.name);
            }
            context.startActivity(intent);
        } catch (ActivityNotFoundException | NullPointerException ignored) {
        }
    }

    public static String replaceToHttps(String uri){
        return uri.replace("http://", "https://");
    }
}
