+# KosSSH Mobile
+
+Android SSH mobile client starter project with interactive PTY, ANSI color rendering, custom terminal font size, keyboard helper keys, and password authentication.
+
+## Build
+
+Open this folder in Android Studio (Ladybug or newer) and let Gradle sync. Then run on an Android 8.0+ device/emulator.
+
+Or from a machine with Gradle/Android SDK configured:
+
+```bash
+./gradlew assembleDebug
+```
+
+APK output:
+`app/build/outputs/apk/debug/app-debug.apk`
+
+## Current features
+
+- SSH shell over JSch (SSH-2)
+- PTY `xterm-256color`
+- Interactive keyboard via InputConnection
+- ANSI SGR basic 16-color + bright color + bold
+- Adjustable monospace font size
+- Dark terminal theme
+- Ctrl+A-Z helper
+- Tab/Esc/arrow helper buttons
+- Host/port/user/password fields
+
+## Important production hardening
+
+This is a functional MVP, not yet a production-grade SSH client. Before shipping, replace `StrictHostKeyChecking=no` in `SshClient.kt` with persistent known-hosts / host-key fingerprint verification, add encrypted profile storage with Android Keystore, private-key authentication, SFTP, terminal resize (`windowChange`), robust VT100/VT220/VT420 parsing, selection/copy, scrollback UI, and connection lifecycle handling.

+#   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.
