+# TDLib Java example
+
+To run this example, you will need installed JDK >= 1.6.
+For Javadoc documentation generation PHP is needed.
+
+TDLib should be prebuilt for using with Java and installed to local subdirectory `td/` as follows:
+```
+cd <path to TDLib sources>
+mkdir jnibuild
+cd jnibuild
+cmake -DCMAKE_BUILD_TYPE=Release -DTD_ENABLE_JNI=ON -DCMAKE_INSTALL_PREFIX:PATH=../example/java/td ..
+cmake --build . --target install
+```
+If you want to compile TDLib for 64-bit Java on Windows using MSVC, you will also need to add `-A x64` option to CMake.
+
+In Windows, use Vcpkg toolchain file by adding parameter -DCMAKE_TOOLCHAIN_FILE=<VCPKG_DIR>/scripts/buildsystems/vcpkg.cmake
+
+Then you can build this example:
+```
+cd <path to TDLib sources>/example/java
+mkdir build
+cd build
+cmake -DCMAKE_BUILD_TYPE=Release -DTd_DIR=<full path to TDLib sources>/example/java/td/lib/cmake/Td -DCMAKE_INSTALL_PREFIX:PATH=.. ..
+cmake --build . --target install
+```
+
+Compiled TDLib shared library and Java example after that will be placed in bin/ and Javadoc documentation in `docs/`.
+
+Now you can run Java example:
+```
+cd <path to TDLib sources>/example/java/bin
+java '-Djava.library.path=.' org/drinkless/tdlib/example/Example
+```
+
+If you get "Could NOT find JNI ..." error from CMake, you need to specify to CMake path to the installed JDK, for example, "-DJAVA_HOME=/usr/lib/jvm/java-8-oracle/".
+
+If you get java.lang.UnsatisfiedLinkError with "Can't find dependent libraries", you may also need to copy some dependent shared libraries to `bin/`.
+
+In case you compiled the example as 32-bit version, you may need to give -d32 parameter to Java.
