These other apps are specified\n [by package name](#package), [by intent\n signature](#intent), or [by provider authority](#provider), as described in\n the following sections on this page.\n\n **Note:** Some packages are\n [visible automatically](/training/package-visibility/automatic). Your\n app always sees these packages in its queries for other installed apps. To\n view other packages, declare your app's need for increased package visibility\n using the `\u003cqueries\u003e` element.\n\n Learn more about how to use the `\u003cqueries\u003e` element in\n [Package visibility filtering on Android](/training/package-visibility).\n\nchild elements:\n:\n\n `\u003cpackage\u003e`\n\n : Specifies a single app that your app intends to access. This other\n app might integrate with your app, or your app might use services that the\n other app provides.\n\n attributes:\n\n `android:name`\n : **Required.** Specifies the package name of the other app.\n\n `\u003cintent\u003e`\n\n : Specifies an [intent filter\n signature](/training/basics/intents/filters). Your app can discover other apps that have matching\n [`\u003cintent-filter\u003e`](/guide/topics/manifest/intent-filter-element)\n elements.\n\n **Note:** There are some restrictions on the\n options that you can include in this `\u003cintent\u003e` element,\n compared to a typical intent filter signature. Learn more about these\n restrictions in [Packages\n that match an intent filter signature](/training/package-visibility/declaring#intent-filter-signature).\n\n `\u003cprovider\u003e`\n\n : Specifies one or more\n [content\n provider authorities](/guide/topics/providers/content-provider-basics#ContentURIs). Your app can discover other apps whose content\n providers use the specified authorities.\n\n **Note:** There are some restrictions on the\n options that you can include in this `\u003cprovider\u003e` element,\n compared to a typical\n [`\u003cprovider\u003e`](/guide/topics/manifest/provider-element)\n manifest element. Usually, you only specify the\n `android:authorities` attribute.\n\nintroduced in:\n: API level 30\n\nsee also:\n: [Package visibility filtering on Android](/training/package-visibility)"]]
