Android(安卓)根据 Url 跳转应用

1. 获取到 url
2. 根据 url 类型做处理
schemes
在 Android ，我们可以定义特定的 schemes url. 然后通过代码：
Intent intent = Intent.parseUri(url, Intent.URI_INTENT_SCHEME);只要有 app 在 AndroidManifest 中定义了相同的 schemes url ，就能直接跳转。
url
如果是普通的以 http,https,ftp 为开头的 url ，我们则可以直接
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));这个时候，系统会弹出多个选项让用户选择用哪个应用启动。但是如果我们想要直接启动对应的应用呢？
private static Intent handleHttpIntent(String url, String tag) { Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url)); ResolveInfo resolveInfo = getResolveInfo(intent, tag); if (null != resolveInfo) { try { intent.setClassName(resolveInfo.activityInfo.packageName, resolveInfo.activityInfo.name); return intent; } catch (Exception e) { e.printStackTrace(); } } return null; } private static ResolveInfo getResolveInfo(Intent intent, String tag) { List resolveInfos = AppUtil.getApp() .getPackageManager() .queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY); for (ResolveInfo resolveInfo : resolveInfos) { //use the title or Remotely configured package name to find the target app if (resolveInfo.activityInfo.packageName.contains(tag)) { return resolveInfo; } } return null; } 这种情况，我们就只能获取所有能跳转的应用列表，通过我们远程配置的 tag 来获取指定跳转的应用了。
