Td: How Can I Build Android Version .i don't want use ready so file

[skydeveloper9]

hi
i want build my project bu I don't want to use your version tdlibjni
The rest of the systems have a complete guide, but the Android file is ready

ا have android ndk and openssl for android
operion system is linux ubuntu

do not send the download link
https://core.telegram.org/tdlib/tdlib.zip

---

please provide complete guidance
how can i build it?

[levlam]

The building for Android is hard, so even the instructions are provided, there is a minor chance that they would work for you. Any change in NDK version or installed libraries can cause the build to fail.

We have Java wrapper available at https://github.com/tdlib/td/blob/master/example/java/td_jni.cpp. It could be used on Android almost without modifications, but you would still need to figure out, how to build the C++ project.

[skydeveloper9]

I'm ready to try
Which versions of ndk do you use?
for build use ndk cmake or install on os cmake?

Java output cannot be used on Android. Because I need a file armabi-v7 so file.

just give me needed command on ubuntu :-)

can you build example/android directory like example/java for open it with android studio??

[levlam]

@skydeveloper9 Do you want to use native Java interface or JSON interface?

[skydeveloper9]

Priority is libtdjni (java native interface)
If not, use libtdjson
In any case, I want to do it myself

[levlam]

Regarding your questions:

Which versions of ndk do you use?

Currently, r19c

for build use ndk cmake or install on os cmake?

OS cmake should be enough.

[skydeveloper9]

ok please give me needed command for compile armeabi-v7

[skydeveloper9]

please publish android studio sample project to build tdlib jni

[skydeveloper9]

i run this command

git checkout tags/v1.6.0 -b v1.6.0;
mkdir build;
cd build;
export CXXFLAGS="";

then

wht's wrong???

[levlam]

You need to generate some source files first:

mkdir native_build
cd native_build
cmake ..
cmake --build . --target prepare_cross_compiling

[skydeveloper9]

tank you @levlam thats work

/home/user/Android/Sdk/cmake/3.6.4111459/bin/cmake --build . --target install;

show this error

ninja: error: '../td/bin/td_generate_java_api', needed by 'CMakeFiles/td_generate_java_api', missing and no known rule to make it
and without ninja is this

make[2]: *** No rule to make target '../td/bin/td/generate/JavadocTlDocumentationGenerator.php', needed by 'CMakeFiles/td_generate_java_api'. Stop. CMakeFiles/Makefile2:170: recipe for target 'CMakeFiles/td_generate_java_api.dir/all' failed make[1]: *** [CMakeFiles/td_generate_java_api.dir/all] Error 2 Makefile:127: recipe for target 'all' failed make: *** [all] Error 2
Which step was wrong?

when use prepare_cross_compiling not generate td_generate_java_api file

[levlam]

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 build-all.sh in the unpacked archive top-level directory to build TDLib.

duplicate #77

@levlambot Yes. You're right. It is rather more like a repeat.

[levlam]

@skydeveloper9 Have you succeeded?

[skydeveloper9]

@skydeveloper9 Have you succeeded?

its work.
But a better way is to put an example of an Android app in example directory like another
thanks
