+# TurnosXpress Android TWA
+
+Minimal Android Trusted Web Activity app for `https://turnosxpress.com.ar`.
+
+## Project
+
+- Package/application id: `com.hdrdevs.turnosxpress`
+- Launch URL: `https://turnosxpress.com.ar`
+- TWA library: `com.google.androidbrowserhelper:androidbrowserhelper:2.7.2`
+- Launcher activity: `com.google.androidbrowserhelper.trusted.LauncherActivity`
+
+## Build
+
+This folder intentionally does not include a Gradle wrapper. Open `tx-android` in Android Studio, or use an installed Gradle distribution:
+
+```powershell
+cd tx-android
+gradle tasks
+gradle assembleDebug
+```
+
+If Android Studio creates `local.properties`, keep it local. It is ignored by Git.
+
+## Signing
+
+For local debug builds Android uses the debug keystore. For Play Store releases, sign with the release keystore or Play App Signing certificate configured for this package.
+
+Example local release keystore creation:
+
+```powershell
+keytool -genkeypair -v -keystore turnosxpress-release.jks -alias turnosxpress -keyalg RSA -keysize 2048 -validity 10000
+```
+
+Do not commit keystores or signing passwords. Put local signing values in `keystore.properties` if you later wire release signing into Gradle.
+
+## SHA-256 Fingerprint
+
+Digital Asset Links must use the SHA-256 fingerprint of the certificate that signs the installed APK.
+
+Debug keystore example:
+
+```powershell
+keytool -list -v -alias androiddebugkey -keystore "$env:USERPROFILE\.android\debug.keystore" -storepass android -keypass android
+```
+
+Release keystore example:
+
+```powershell
+keytool -list -v -alias turnosxpress -keystore .\turnosxpress-release.jks
+```
+
+If Play App Signing is enabled, use the SHA-256 fingerprint from Play Console's app signing certificate, not only the upload key.
+
+## Digital Asset Links
+
+Publish this file publicly at:
+
+```text
+https://turnosxpress.com.ar/.well-known/assetlinks.json
+```
+
+Example:
+
+```json
+[
+ {
+ "relation": ["delegate_permission/common.handle_all_urls"],
+ "target": {
+ "namespace": "android_app",
+ "package_name": "com.hdrdevs.turnosxpress",
+ "sha256_cert_fingerprints": [
+ "AA:BB:CC:DD:EE:FF: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"
+ ]
+ }
+ }
+]
+```
+
+The JSON must be served over HTTPS with `Content-Type: application/json` and no redirects that break access to `/.well-known/assetlinks.json`.
+
+## Play Protect And Local APK Notes
+
+Local APK installs can show Play Protect warnings because the APK is not installed from Google Play and may be signed by a new or unknown certificate. This is expected during sideload testing and does not prove the TWA or Digital Asset Links setup is wrong.
+
+The full-screen trusted experience only works when Android can verify the website-to-app relationship through Digital Asset Links for the certificate used to sign that APK. Until that is valid, Chrome may open the site with browser UI or behave like a Custom Tab.

+# Gradle start up script for POSIX generated by Gradle.
+#
+# Important for running:
+#
+# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+# noncompliant, but you have some other compliant shell such as ksh or
+# bash, then to run this script, type that shell name before the whole
+# command line, like:
+#
+# ksh Gradle
+#
+# Busybox and similar reduced shells will NOT work, because this script
+# requires all of these POSIX shell features:
+# * functions;
+# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+# * compound commands having a testable exit status, especially «case»;
+# * various built-in commands including «command», «set», and «ulimit».
+#
+# Important for patching:
+#
+# (2) This script targets any POSIX shell, so it avoids extensions provided
+# by Bash, Ksh, etc; in particular arrays are avoided.
+#
+# The "traditional" practice of packing multiple parameters into a
+# space-separated string is a well documented source of bugs and security
+# problems, so this is (mostly) avoided, by progressively accumulating
+# options in "$@", and eventually passing that to Java.
+#
+# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+# see the in-line comments for details.
+#
+# There are tweaks for specific operating systems such as AIX, CygWin,
+# Darwin, MinGW, and NonStop.
+#
+# (3) This script is generated from the Groovy template
+# https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+# within the Gradle project.
