# Build
Most of the original gocryptfs code was used as is (written in Go) and compiled to native code. That's why you need [Go](https://golang.org) and the [Android Native Development Kit (NDK)](https://developer.android.com/ndk/) to build DroidFS from source.
#### Install Requirements
- [Android Studio](https://developer.android.com/studio/)
- [Android NDK and CMake](https://developer.android.com/studio/projects/install-ndk) (OpenSSL build fails with NDK versions higher than v22. It should pass with NDK v21.4.7075529 and lower)
- [Go](https://golang.org/doc/install) (on debian: `$ sudo apt-get install golang-go`)
#### Install dependencies
On debian:
```
$ sudo apt-get install build-essential pkg-config libssl-dev
```
Install [Go](https://golang.org/doc/install):
```
$ sudo apt-get install golang-go
```
You also need to install the Android SDK build tools and the [Android NDK](https://developer.android.com/studio/projects/install-ndk).

#### Build
First, we need to install some dependencies:
```
$ sudo apt-get install libcrypto++-dev libssl-dev pkg-config
#### Generate a keystore
APKs must be signed to be installed on an Android device. If you don't already have a keystore, you can generate one by running:
```
And also Go dependencies:
$ keytool -genkey -keystore <output file> -alias <key alias> -keyalg EC -validity 10000
```
$ go get golang.org/x/sys/unix golang.org/x/sys/cpu golang.org/x/crypto/hkdf github.com/jacobsa/crypto/siv github.com/rfjakob/eme
```
Then, retrieve your Android NDK installation path, usually someting like "/home/\<user\>/Android/SDK/ndk/\<NDK version\>". We can now build libgocryptfs:
#### Build
Retrieve your Android NDK installation path, usually something like "/home/\<user\>/Android/SDK/ndk/\<NDK version\>". Now you can build libgocryptfs:
```
$ cd DroidFS/app/libgocryptfs
$ env ANDROID_NDK_HOME="<your ndk path>" OPENSSL_PATH="./openssl-1.1.1m" ./build.sh
```
And also FFmpeg:
Then FFmpeg:
```
$ cd app/ffmpeg
$ env ANDROID_NDK_HOME="<your ndk path>" ./build.sh ffmpeg
```
Then, open the DroidFS project with Android Studio. \
If a device (virtual or physical) is connected, just click on "Run". \
If you want to generate a signed APK, you can follow this [post](https://stackoverflow.com/a/28938286).
Finally, compile the app:
```
$ ./gradlew assembleRelease
```
If the build succeeds, you will find the unsigned APKs in `app/build/outputs/apk/release/`. You need to sign them in order to install the app:
```
$ apksigner sign --out droidfs.apk -v --ks <keystore> app/build/outputs/apk/release/<unsigned apk file>
```
Now you can install `droidfs.apk` on your device.
