Ejemplo: Comparte credenciales en varios sitios web y apps para Android
Organiza tus páginas con colecciones Guarda y categoriza el contenido según tus preferencias.
Para configurar el uso compartido de credenciales en varios sitios web y varias apps para Android, debes hacer lo siguiente:
Designa un dominio principal: Elige una URL como el punto de referencia principal para los vínculos.
Crear archivos assetlinks.json:
Dominio principal: Crea un archivo assetlinks.json en tu dominio principal que enumere todos los dominios que comparten credenciales.
Otros dominios: Crea un archivo assetlinks.json en cada uno de los otros dominios, cada uno de los cuales se vincula al dominio principal.
Configura la vinculación de recursos digitales en el manifiesto de cada app: Configura cada app para que se vincule al archivo assetlinks.json en el dominio principal.
En el siguiente ejemplo, designamos example.com como el dominio principal, y todos los demás dominios enumerados comparten credenciales con example.com y entre sí.
Aloja el archivo JSON de Vínculos de recursos digitales en la ubicación conocida correspondiente del dominio principal, en este caso: https://example.com/.well-known/assetlinks.json.
Crea otro archivo assetlinks.json con el siguiente contenido:
Para configurar la vinculación de recursos digitales en el manifiesto, declara la asociación en la app para Android. Agrega un objeto que especifique los archivos assetlinks.json que se cargarán. En este caso, ocurre lo siguiente:
Después de seguir estos pasos, habrás configurado correctamente el uso compartido de credenciales sin problemas en varios sitios web y apps para Android.

Create an `assetlinks.json` file with the following content:\n\n [\n {\n \"relation\": [\"delegate_permission/common.get_login_creds\"],\n \"target\": {\n \"namespace\": \"web\",\n \"site\": \"https://example.com\"\n }\n },\n {\n \"relation\": [\"delegate_permission/common.get_login_creds\"],\n \"target\": {\n \"namespace\": \"web\",\n \"site\": \"https://example.org\"\n }\n },\n {\n \"relation\": [\"delegate_permission/common.get_login_creds\"],\n \"target\": {\n \"namespace\": \"web\",\n \"site\": \"https://example.net\"\n }\n },\n {\n \"relation\": [\"delegate_permission/common.get_login_creds\"],\n \"target\": {\n \"namespace\": \"web\",\n \"site\": \"https://myownpersonaldomain.com\"\n }\n },\n {\n \"relation\" : [\n \"delegate_permission/common.get_login_creds\"\n ],\n \"target\" : {\n \"namespace\" : \"android_app\",\n \"package_name\" : \"com.example.android.myapplication\",\n \"sha256_cert_fingerprints\" : [ \"AA:BB:CC:DD:EE:FF:11:22:33:44:55:66:77:88:99:00:AA:BB:CC:DD:EE:FF:11:22:33:44:55:66:77:88:99:00\"\n ]\n }\n },\n {\n \"relation\" : [\n \"delegate_permission/common.get_login_creds\"\n ],\n \"target\" : {\n \"namespace\" : \"android_app\",\n \"package_name\" : \"com.example.appname\",\n \"sha256_cert_fingerprints\" : [ \"00:11:22:33:44:55:66:77:88:99:AA:BB:CC:DD:EE:FF:00:11:22:33:44:55:66:77:88:99:AA:BB:CC:DD:EE:FF\"\n ]\n }\n }\n ]\n\n2.

Configure digital asset linking in the manifest by declaring the association\n in the Android app. Add an object that specifies the `assetlinks.json` files\n to load.
