# Establishing a Build Environment ## Installing the Android NDK The Android NDK is required to build native modules for Android. Download the NDK r19 or newer archive from the following site: [Download the Android NDK on developer.android.com](https://developer.android.com/ndk/downloads/index.html) To install the Android NDK, simply expand the archive in the folder where you want to install it. ## OpenSSL Google removed openssl from Android 7+. You must build openssl libs by yourself. # Configure the NDK path Edit the `mkall` script to configure NDK path. Set the `NDK` to the directory where the NDK is installed. # Build SRT for Android Run `/bin/bash mkall > build.log` script. Libraries will be installed to `./target-architecture/lib`. # Export SRT libraries Run `/bin/bash packjni` to generate `jniLibs` archive for Android Studio.
