Android Prerequisites

1. The following packages are required by the build scripts.

autoconf automake libtool pkg-config curl git doxygen nasm

2. These optional packages should be installed only if you want to build corresponding external libraries.

• autogen required for libsndfile
• bison > 2.4, wget, autopoint required for gnutls
• cmake > 3.9 required by libwebp and x265
• gcc required by freetype and fribidi
• gperf required by fontconfig

• meson > 0.56, ninja for dav1d

3. Android builds require these additional packages.

• Android SDK Build Tools

4. Set ANDROID_SDK_ROOT and ANDROID_NDK_ROOT environment variables to point to their exact locations.
