+# How to build Keepass2Android
+
+## Overview
+
+Keepass2Android is a Mono for Android app. This means that you need Xamarin's Mono for Android to build it. However, it also uses several components written in Java, so there are also Android-Studio projects involved. To make things even worse, parts of the keyboard and kdb-library are written in native code.
+
+To build KP2A from scratch, you need:
+- Xamarin's Mono for Android (also included in Visual Studio)
+- Android SDK & NDK
+
+Prior to building Keepass2Android, you need to build some of its components (from command line). Then you can build the full project either through Visual Studio, or through command line.
+
+By using the command line, you can build on Windows, macOS or Linux.
+
+## Prerequisites
+
+### Common to all architectures
+- Install Android SDK & NDK (either manually with Google's [sdkmanager](https://developer.android.com/studio/command-line/sdkmanager), or through Android Studio). Visual Studio also installs a version of it, but in the end the directory must be writable and in a path without spaces (see below) so as to be able to build the components.
+- Fetch the main repository of Keepass2Android and all submodules
+    - Note that VisualStudio can do this for you, otherwise run:
+    - `git submodule init && git submodule update`
+
+### On Windows or macOS
+- Install Visual Studio (for example 2019) with Xamarin.Android (ie. with capability to build Android apps). This should provide the needed tools like
+    - Xamarin.Android
+    - MSBuild
+    - Java JDK
+- If you plan to build also from the command line:
+    - Install the MSVC build tools of visual studio. They provide the `vcvarsall.bat` file which among other things adds MSBuild to the PATH.
+    - Install [NuGet](https://www.nuget.org/downloads) to build also with "make". Alternatively, on Windows, if you use [chocolatey](https://chocolatey.org), run as administrator:
+      - `choco install nuget.commandline`
+    - Check that you have access to 'GNU make'.
+      - On Windows, it is usually not available by default. But the Android NDK provides it. You can find it in `%ANDROID_NDK_ROOT%\prebuilt\windows-x86_64\bin\make.exe`.  Alternatively, on Windows, if you use [chocolatey](https://chocolatey.org), run as administrator:
+        - `choco install make`
+      - On macOS, it is usually only installed if you have developer command line tools installed or if you use [homebrew](https://brew.sh) or [macports](https://www.macports.org/). As an alternative it may be available in the Android NDK at `%ANDROID_NDK_ROOT%/prebuilt/darwin-x86_64/bin/make`.
+
+### On Linux
+- Install Java's JDK
+    - On Debian, for example: `apt install default-jdk-headless`.
+
+- Install [Mono](https://www.mono-project.com/)
+    - This should provide `msbuild` & `xabuild` binary
+    - On Debian, after having added the repo from above, install with `apt install -t <repo_name> mono-devel msbuild`. A value for `<repo_name>` could be `stable-buster` for example, depending on which one you chose. You could also install the `mono-complete` package if you prefer.
+
+- Install Xamarin.Android
+  - Option 1: Use the mono-project [CI builds](https://dev.azure.com/xamarin/public/_build/latest?definitionId=48&branchName=main&stageName=Linux)
+  - Option 2: [Build it from source](https://github.com/xamarin/xamarin-android/blob/master/Documentation/README.md#building-from-source)
+
+- Install NuGet package of your distribution
+    - On Debian/Ubuntu: `apt install nuget`
+
+- Install [libzip](https://libzip.org/) for your distribution for some Xamarin.Android versions
+  - This may not be relevant anymore: for example, with Xamarin.Android 11.4.99. this is not needed.
+  - Some versions of Xamarin may require `libzip4`. If you are in this case:
+    - On Debian/Ubuntu, install it with `apt install libzip4`.
+    - Other distributions ship only `libzip5`. As a dirty workaround, it's possible to symlink `libzip.so.5` to `libzip.so.4`. Luckily, it appears to be working. For example:
+      - `sudo ln -s /usr/lib/libzip.so.5 /usr/lib/libzip.so.4`
+      - or `sudo ln -s /usr/lib64/libzip.so.5 /usr/lib/libzip.so.4`
+
+## Building the required components:
+
+This is done on the command line and requires the Android SDK & NDK and Java JDK.
+
+### On Windows
+- Setup your environment:
+  - Set these environment variables for Android's SDK & NDK
+    - `ANDROID_HOME` (for example `set ANDROID_HOME=C:\PATH\TO\android-sdk\`)
+    - `ANDROID_SDK_ROOT` (for example `set ANDROID_SDK_ROOT=C:\PATH\TO\android-sdk\`)
+    - `ANDROID_NDK_ROOT` (for example `set ANDROID_NDK_ROOT=C:\PATH\TO\android-sdk\ndk\version\`)
+
+    **Note**: If the path to the Android SDK contains spaces, you **must** do one of these:
+    - either put the Android SDK into a path without spaces.
+    - or create a symlink to that path which doesn't contain spaces. Attention: this requires **administrator** priveleges. For example:
+
+        ```
+        IF NOT EXIST C:\Android ( MKDIR C:\Android ) && 
+        MKLINK /D C:\Android\android-sdk "C:\Program Files (x86)\Android\android-sdk" 
+        ```
+    This is because [Android NDK doesn't support being installed in a path with spaces](https://github.com/android/ndk/issues/1400).
+
+    **Note**: The Android SDK path will require to be writeable because during the build, some missing components might be downloaded & installed.
+
+- If you have "GNU make" available on your windows system, you may build by using the Makefile. You can also find a `make` executable in `%ANDROID_NDK_ROOT%\prebuilt\windows-x86_64\bin\make.exe`. To use it, see the instructions for Linux/macOS. Basically, just run `make` or `mingw32-make` depending on which distribution of GNU make for windows you have installed.
+
+- Otherwise proceed as below:
+
+    1. Build argon2
+
+        ```
+        cd src/java/argon2
+        %ANDROID_NDK_ROOT%/ndk-build.cmd
+        ```
+    1. Build the other java components
+
+        ```
+        cd src/build-scripts
+        build-java.bat
+        ```
+
+        `build-java.bat` will call `gradlew` for several Java modules.
+
+**Notes:**
+
+ - For building the java parts, it is suggested to keep a short name (e.g. "c:\projects\keepass2android") for the root project directory. Otherwise the Windows path length limit might be hit when building.
+ - Before building the java parts, make sure you have set the ANDROID_HOME variable or create a local.properties file inside the directories with a gradlew file. It is recommended to use the same SDK location as that of the Xamarin build.
+
+
+### On Linux/macOS
+
+- Setup your environment:
+  - Set these environment variables for Android's SDK & NDK
+    - `ANDROID_HOME` (for example `export ANDROID_HOME=/path/to/android-sdk/`)
+    - `ANDROID_SDK_ROOT` (for example `export ANDROID_SDK_ROOT=/path/to/android-sdk/`)
+    - `ANDROID_NDK_ROOT` (for example `export ANDROID_NDK_ROOT=/path/to/android-sdk/ndk/version`)
+
+- Update your PATH environment variable so that it can access `nuget`, `msbuild` or `xabuild` (for linux):
+    - On Linux:
+        - add `xabuild` to your path: `export PATH=/path/to/xamarin.android-oss/bin/Release/bin/:$PATH`
+    - On macOS:
+        - you may similarly need to add `msbuild` & `nuget` to your PATH.
+
+- Start the build:
+    - This will use the Makefile at the root of the project (requires GNU make). To build everything (components & Keepass2Android APK) in a single command simply run:
+
+        ```
+        make
+        ```
+
+    - Otherwise, if you prefer to do step by step
+
+        1. Build argon2
+
+            ```
+            make native
+            ```
+
+        1. Build the other java components
+
+            ```
+            make java
+            ```
+
+## Building Keepass2Android:
+
+These are the basic steps to build Keepass2Android. You can also build Keepass2Android Offline. For this, configure the build by using the [Flavors](#Flavors).
+
+### With Visual Studio
+
+- On windows or on macOS open the src/KeePass.sln file with visual studio, and choose to build the project named 'keepass2android-app'
+
+### Command Line
+
+#### Windows, Macos & Linux
+to build the APK, simply run:
+
+```
+    make
+```
+
+or to skip building the APK:
+
+```
+    make msbuild
+```
+
+## Where is the APK ?
+The Apk can be installed on a device.
+It is located in `src/keepass2android/bin/*/*-Signed.apk`
+
+If you build with Visual Studio, the APK is not produced automatically. You need to perform some extra step. See the documentation of Visual Studio on how to proceed.
+
+## Flavors
+
+Keepass2Android is distributed in two flavors.
+  - Keepass2Android (aka `net`)
+  - Keepass2Android Offline (aka `nonet`)
+
+The flavor is set through a MSBuild Property named "`Flavor`". The possible values are '`Net`' and '`NoNet`'.
+
+The value of the Flavor property is used in 2 projects:
+  - `keepass2android-app` (in `src/keepass2android`)
+  - `Kp2aBusinessLogic` (in `src/keepass2android`)
+
+Its value is set inside the `*.csproj` file (XML format) of each project in the `Project`/`PropertyGroup`/`Flavor` node.
+By default its value is set to an empty string so that development is made with `AndroidManifest_debug.xml` on the '`net`' flavor.
+
+This is the behaviour of the build system depending on the value of Flavor:
+| Flavor                                     | What is built           | `AndroidManifest.xml` used  |
+| -----                                      | -----                   | -----                       |
+| `` (empty string): This is the default value. | Keepass2Android      | `AndroidManifest_debug.xml` |
+| `Net`                                      | Keepass2Android         | `AndroidManifest_net.xml`   |
+| `NoNet`                                    | Keepass2Android Offline | `AndroidManifest_nonet.xml` |
+
+### Select/Change flavor:
+
+When building, by default, the flavor is not set. So the value used is the value of the Flavor property in *.csproj file. This should result on doing a build of the 'net' flavor.
+
+You can force the Flavor by setting the Flavor property.
+
+Proceed this way:
+
+#### Command line
+
+##### Windows, Macos & Linux
+
+To force building 'net' with `make`, run:
+
+```
+    make Flavor=Net
+```
+
+To build 'nonet' with `make`, run:
+
+```
+    make Flavor=NoNet
+```
+
+##### MSBuild
+
+To build with MSBuild directly on the command line, set the flavor with `-p:Flavor=value` argument. For example:
+
+```
+    MSBuild src/KeePass.sln ... -p:Flavor=NoNet
+```
+
+#### Visual Studio
+When building with Visual Studio, edit the `*.csproj` file (XML format) and set the value in the `Project`/`PropertyGroup`/`Flavor` node. This is needed only for the projects that use the flavors.
+
+**Note:** When switching between flavors, be sure to clean the previous build before.
+
+## Makefile
+
+It is possible to override the project's default 'Flavor' (Net, NoNet) and 'Configuration' (Release, Debug) by passing it as argument to `make`. See the header of the Makefile to see what can be done.

-This directory is for Android .jars.
-
-There are 3 types of jars that are supported:
-
-== Input Jar and Embedded Jar ==
-
-This is the jar that bindings should be generated for.
-
-For example, if you were binding the Google Maps library, this would
-be Google's "maps.jar".
-
-The difference between EmbeddedJar and InputJar is, EmbeddedJar is to be
-embedded in the resulting dll as EmbeddedResource, while InputJar is not.
-There are couple of reasons you wouldn't like to embed the target jar
-in your dll (the ones that could be internally loaded by <uses-library>
-feature e.g. maps.jar, or you cannot embed jars that are under some
-proprietary license).
-
-Set the build action for these jars in the properties page to "InputJar".
-
-
-== Reference Jar and Embedded Reference Jar ==
-
-These are jars that are referenced by the input jar.  C# bindings will
-not be created for these jars.  These jars will be used to resolve
-types used by the input jar.
-
-NOTE: Do not add "android.jar" as a reference jar.  It will be added automatically
-based on the Target Framework selected.
-
-Set the build action for these jars in the properties page to "ReferenceJar".
-
-"EmbeddedJar" works like "ReferenceJar", but like "EmbeddedJar", it is
-embedded in your dll. But at application build time, they are not included
-in the final apk, like ReferenceJar files.

-# How to build Keepass2Android
-
-## Overview
-
-Keepass2Android is a Mono for Android app. This means that you need Xamarin's Mono for Android to build it. However, it also uses several components written in Java, so there are also Android-Studio projects involved. To make things even worse, parts of the keyboard and kdb-library are written in native code.
-The current build-scripts assume that the native libraries are already built (they are included in the repo). 
-
-To build KP2A from scratch, make sure that you have Xamarin's Mono for Android installed and also install Android Studio. Make sure that both point to the same Android SDK location.
-
-## Prerequisites
-
-- Install Xamarin.Android
-- Fetch all submodules (`git submodule init && git submodule update`)
-
-## Build
-
-### On Windows
-
-```bat
-cd build-scripts
-build-java.bat
-build-xamarin.bat
-```
-
-build-java.bat will call gradlew for several Java modules. build-xamarin.bat will first make sure that you have all files at their place. (There is a "secret" file for Dropbox SDK keys which is not in the repo, this is replaced with a dummy file. There are also different Android Manifest files depending on the configuration which is selected by calling the appropriate script.)
-
-**Notes:**
-
- - For building the java parts, it is suggested to keep a short name (e.g. "c:\projects\keepass2android") for the root project directory. Otherwise the Windows path length limit might be hit when building.
- - Before building the java parts, make sure you have set the ANDROID_HOME variable or create a local.properties file inside the directories with a gradlew file. It is recommended to use the same SDK location as that of the Xamarin build.
-
-### On Linux
-
-- Install [Mono](https://www.mono-project.com/)
-- Install Xamarin.Android
-  - Option 1: Use the mono-project [CI builds](https://jenkins.mono-project.com/view/Xamarin.Android/job/xamarin-android-linux/lastSuccessfulBuild/Azure/)
-  - Option 2: [Build it from source](https://github.com/xamarin/xamarin-android/blob/master/Documentation/README.md#building-from-source)
-- Setup your environment:
-  - Add `xabuild` to your path: `export PATH=/path/to/xamarin.android-oss/bin/Release/bin/:$PATH`
-  - Setup your `ANDROID_HOME` if it's not already: `export ANDROID_HOME=/path/to/android/`
-  - Alternatively, you can set your `ANDROID_SDK_PATH` and `ANDROID_NDK_PATH`.
-- Build [jar2xml](https://github.com/xamarin/jar2xml) and copy `jar2xml.jar` to `/path/to/xamarin.android-oss/bin/Release/lib/xamarin.android/xbuild/Xamarin/Android/`
-- Install [libzip](https://libzip.org/) for your distribution.
-  - Note: Xamarin seems to require `libzip4`, yet most distributions only ships `libzip5`. As a dirty workaround, it's possible to symlink `libzip.so.5` to `libzip.so.4`. Luckily, it appears to be working.
-  - `sudo ln -s /usr/lib/libzip.so.5 /usr/lib/libzip.so.4`
-  - or `sudo ln -s /usr/lib64/libzip.so.5 /usr/lib/libzip.so.4`
-- Install NuGet dependencies:
-  - `cd src/ && nuget restore KeePass.sln`
-- Build:
-  - Option 1: `cd build-scripts && ./build-all.sh`
-  - Option 2:
-    - Build the Java parts: `cd build-scripts/ && ./build-java.sh`
-    - Build the Xamarin parts: `./build-xamarin.sh`
-    - Build the signed APK: `./build-apk.sh`
-- Enjoy:
-  - `adb install ../keepass2android/bin/Debug/keepass2android.keepass2android_debug-Signed.apk`
