Android獲取默認浏覽器信息

Android系統可以用如下方法獲取默認浏覽器信息：

public static ActivityInfo getBrowserApp(Context context) {
String default_browser = "android.intent.category.DEFAULT";
String browsable = "android.intent.category.BROWSABLE";
String view = "android.intent.action.VIEW";


Intent intent = new Intent(view);
intent.addCategory(default_browser);
intent.addCategory(browsable);
Uri uri = Uri.parse("http://");
intent.setDataAndType(uri, null);


// 找出手機當前安裝的所有浏覽器程序
List resolveInfoList = context.getPackageManager().queryIntentActivities(intent, PackageManager.GET_INTENT_FILTERS);
if (resolveInfoList.size() > 0) {
ActivityInfo activityInfo = resolveInfoList.get(0).activityInfo;
String packageName = activityInfo.packageName;
String className = activityInfo.name;
return activityInfo;
} else {
return null;
}
}
