==================
Deep Link Handling
==================
Deep linking in Android allows your application to be launched directly from a URL,
making it easier for users to navigate to specific content within your app.
Starting from Android 12, handling deep links requires additional configuration
using an assetlinks.json file to ensure the app and the host domain are properly
associated.
Deep Linking in Android 11 and Below
====================================
For Android 11 and below, deep linking is straightforward and does not require additional
configuration beyond the usual manifest settings.
Deep Linking in Android 12 and Above
------------------------------------
For Android 12 and above, an additional configuration step is required to verify the
relationship between your app and the host domain using the assetlinks.json file.
Creating assetlinks.json:
-------------------------
Create a file named assetlinks.json and host it in the .well-known directory of
your website (e.g., https://www.cloud.example.com/.well-known/assetlinks.json).
Example assetlinks.json::
[
{
"relation": ["delegate_permission/common.handle_all_urls"],
"target": {
"namespace": "android_app",
"package_name": "com.cloud.example.nextcloud",
"sha256_cert_fingerprints": [
"APP_SHA256_FINGERPRINT"
]
}
}
]
Replace APP_SHA256_FINGERPRINT with the SHA-256 fingerprint of your apps
signing certificate.
Nextcloud Configuration Limitation
==================================
Due to the additional requirement of hosting an assetlinks.json file
for Android 12 and above, Nextcloud cannot configure the Android client
for all different hosts. This is because each host needs its own assetlinks.json
file to establish a verified relationship with the app, and Nextcloud cannot manage
this file for every possible host domain.
