I prepared scripts which can be used to build all flavours of TDLib for Android. You will need Bash, cmake, ninja, C++14 compatible compiler, PHP (optional, for documentation generation), Android NDK and system JDK preinstalled. Make sure that ANDROID_SDK_ROOT environment variable is correctly set before using the scripts.

I prepared scripts which can be used to build all flavours of TDLib for Android. You will need Bash, cmake, ninja, C++14 compatible compiler, PHP (optional, for documentation generation), Android NDK and system JDK preinstalled. Make sure that ANDROID_SDK_ROOT environment variable is correctly set before using the scripts.

You can build desired TDLib version using:
libtdjni.zip - native JNI wrapper for TDLib with autogenerated Java classes.
libtdjsonandroid.zip - TDLib JSON interface built for Android. All TDLib JSON interface methods have ordinary names prefixed with undescore, for example _td_json_client_create.
libtdjsonjava.zip - JNI wrapper for TDLib JSON interface.

You will need to unpack the desired archive to td/example directory. Then download the latest OpenSSL 1.1.1 source code as a .tar.gz archive from OpenSSL 1.1.1 release page and place it in the third_party/crypto subfolder. After that you need to adjust variables ANDROID_NDK and HOST_ARCH in third_party/crypto/build.sh and run third_party/crypto/build-all.sh script to build OpenSSL.
After that run the script export.sh in the unpacked archive top-level directory to build TDLib.

And this is relevant how, exactly?
