Android 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<ResolveInfo> 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。
