-# Android (Java) wrapper
-
-## Requirements
-
-You will need to install the JDK compatible with Gradle and the Android Gradle plugin. Gradle specifies
-a [maximum supported JDK version](https://docs.gradle.org/current/userguide/compatibility.html), while the Android
-Gradle plugin specifies a [minimum supported JDK version](https://developer.android.com/studio/releases/gradle-plugin) (
-see 'Compatibility' table for the right Gradle version). Additionally, the Android Gradle plugin requires
-a [certain Gradle version range](https://developer.android.com/studio/releases/gradle-plugin#updating-gradle). Lastly, (
-older versions of) Android Studio and especially IntelliJ Ultimate may not support some newer Android Gradle plugin
-versions.
-
-If you see `Unsupported class file major version xx` then Gradle wants you to use an older Java version. If you
-see `Android Gradle plugin requires Java xx to run.` then the Android Gradle plugin wants you to use a newer Java
-version. Set `JAVA_HOME` to the right JDK install.
-
-See the [list of Gradle releases](https://github.com/gradle/gradle/releases)
-and [list of Android Gradle plugin releases](https://maven.google.com/web/?q=com.android.tools.build#com.android.tools.build:gradle)
-.
-
-Versions are managed per project by
-the [Gradle wrapper](https://docs.gradle.org/current/userguide/gradle_wrapper.html) (see `gradle*` files).
-Run `./gradlew --version` to get the project Gradle version. Look at the dependencies in `/build.gradle` for the current
-Android Gradle plugin version. This means that you do not need to install Gradle separately yourself.
-
-Currently, versions are Gradle 7.0.2 and Android Gradle plugin 7.0.4, which means you have to install a **JDK with a
-version between 11 and 16**. If desired, these can be upgraded to e.g. 7.4 and 7.1.1 respectively without problems, but
-as mentioned, IDE support may be limited with newer versions. The Gradle wrapper may be updated using
-e.g. `./gradlew wrapper --gradle-version 7.4`. After that, the Android Gradle plugin may be updated by changing the
-version in `/build.gradle`.
-
-You will also need the Android SDK, which comes with [Android Studio](https://developer.android.com/studio/).
-
-## Build & test
-
-Build AAR (Gradle will also run unit tests):
-
-```shell
-make
-```
-
-This will build an AAR in `lib/build/outputs/aar`, which will include the shared Go library for all Android
-architectures, which it will build using the Android NDK via CMake, which calls `make` with the right compiler.
-
-Run unit tests without an Android emulator:
-
-```shell
-make unit-test
-```
-
-This will build the library for your current desktop OS and use that.
-
-Run Android instrumented tests on a new emulator:
-
-```shell
-make android-test
-```
-
-This uses [Gradle managed virtual devices](https://developer.android.com/studio/preview/features#gmd). This experimental
-feature is enabled in `gradle.properties`. It is normal that tests that pass are not logged.
-
-Run Android instrumented tests on an already running emulator:
-
-```shell
-make connected-android-test
-```
-
-This will be faster when used multiple times, as the emulator is reused.
-
-Run both unit tests and Android instrumented tests on a new emulator:
-
-```shell
-make test
-```
-
-For all commands you can specify options to pass to Gradle via `GRADLE_FLAGS=`, e.g. `GRADLE_FLAGS=--info`.
-Specify `NO_DAEMON=1` to add `--no-daemon`.
-
-## Notes
-
-The same Java code is used for the Android instrumented tests as for the unit tests. Both use Java resources that are
-copied from the `../../src/test_data` folder by Gradle.
-
-This library uses JNA, not JNI. Hence, there is no C wrapper. The library is dynamically opened with `dlopen`
-via `libjnidispatch.so` which comes with the JNA AAR.
-
-If you want to know how the tests would look like with JUnit 5, or if for some reason you want to look at a pure Java
-wrapper using Maven,
-see [`b60ecf2`](https://github.com/stevenwdv/eduvpn-common/tree/b60ecf2fe5ddfe506e02093286b3931873187e91/wrappers/java).

-#
-#   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/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
-#       within the Gradle project.
