td 🚀 - How to build .so file for android?

You can use our Java example to build the library for Android yourself. It could be used almost without modifications. You can also download prebuilt Android library available at http://core.telegram.org/tdlib/tdlib.zip.

I follow the instruction but it's not generate .so file. i want to know how to get .so file from this library like the prebuilt Android library at http://core.telegram.org/tdlib/tdlib.zip.
i try on ubuntu and get libtdjni.so but it's size is about 18mb.

What instructions you have followed?

levlam on 14 Feb 2018

this one example/java

To build TDLib for Android you need to use Android NDK. You can use JNI bindings from Java example, but CMakeLists.txt should be adopted to build everything using NDK.

levlam on 16 Feb 2018

can you give me a instruction to how to do it?

mrH3ktor on 17 Feb 2018

We will publish example project later.

I tried to use prebuilt Android library available at http://core.telegram.org/tdlib/tdlib.zip, but for some reason I always received error: "File "/td.binlog" can't be opened/created for reading and writing"
Could you please tell me what's the problem?

You haven't specified databaseDirectory available for writing in setTdlibPatameters.

We recommend to use CMake for Android builds, which automatically will manage all dependencies.

It seems to me that it remains to understand why one does not see in one namespace
../prog/android-sdk/ndk-bundle/testproj/jni/td/telegram/ClientJson.h:24: undefined reference to `td::Client::Client()'
I can be mistaken, but if you know how to correct, then tell me :)

td_json_client_create() - managed to collect
the rest is not yet clear

isopen on 13 Mar 2018

You need to link against tdclient, tdutils and other libraries.

@isopen you need to run native build first with

cmake --build . --target prepare_cross_compiling

to generate some source files.

Did not appear libtdjson.so(joke). Perhaps it's warnings and errors in the assembly.
Especially the last full meat :) Perhaps it is in openssl...

libtdjson.so(weight 150mb) appeared in the /home/user/proj/td/jnibuild/
But I'm not sure about this meat ...

Something wrong with yours TDLib source code. There is no c == '16' on this line:
https://github.com/tdlib/td/blob/6c706f45e7a73c936b9f2f267785092c8a73348f/tdutils/td/utils/JsonBuilder.cpp#L433
as there is no line

case '16':

For Android it is better to use ANDROID_STL=c++_static additionally to ANDROID_TOOLCHAIN=clang.

levlam on 14 Mar 2018

Yes '16' is just not a critical warning(it does not apply to your code). I'm sorry my girlfriend added this. I'll try to explain to her about the type char.

i try -DANDROID_STL=c++_static
Maybe there will not be this

This is not very critical.:))

That's what I'm interested:

Why does it output libtdjson.so instead of libtdjni.so?

But there is no jni initialization.
Are these lines not exactly needed?

To use native Java bindings you need to use Td::TdStatic library compiled with TD_ENABLE_JNI and the wrapper exactly the same as in our Java example. You will need to additionally compile td_jni.cpp and link it with Td::TdStatic to obtain libtdjni.so.
It is not stripped file. You need to strip them using strip from NDK.
These warnings will be fixed.

Good.

(1) This is not about the current manual :)
CMakeLists.txt
It turns out that this condition is redundant(those. not always like this).

"error: /usr/lib/jvm/java-8-openjdk-i386/jre/lib/i386/server/libjvm.so: incompatible target" is because you have removed check if (TD_ENABLE_JNI AND NOT ANDROID) # jni is available by default on Android and CMake has found wrong JNI libraries, instead of the correct one. To build for Android you should use CMake which is a part of Android NDK.

I'm using this CMake to build (It seems to be part of the NDK)
https://developer.android.com/ndk/guides/cmake.html
With this check does not see jni at all if (TD_ENABLE_JNI AND NOT ANDROID)
So I wrote down like this if (TD_ENABLE_JNI)
Next, I set the paths to jni (with great certainty that this jni would not work - It turned out to be true)
Please tell me where to get the right jni?

isopen on 15 Mar 2018

Correct JNI headers can be found inside Android NDK. I'm not sure that you need to link with JRE libraries on Android at all when JNI is used.

We built TDLib for Android inside Android Studio project. It is hard to drop the whole project, but we will be publish it in the future.

For Android builds it is better to use MinSizeRel instead of Release.

You need to strip the file to reduce its size. Between, it will be automatically stripped before deploying to a device.

levlam on 17 Mar 2018

Thanks @levlam. Everything worked out.

As a material for thought:
If you collect through android-27 and found version openssl 1.0.2j for android then the assembly will hang here

MessagesManager.cpp:15709:31: warning: lambda capture 'thumbnail_file_id' is not used [-Wunused-lambda-capture]

In fact, the files are already created and can be used. This is likely already on the side of android, but it still needs to be checked. It's worth waiting for some assembly is completed.

@isopen , Can you show the hierarchy of your project directory and the CMakeList.txt? I am trying to build Tdlib for my own project, and I just have little of knowledge about Cmake and NDK. :(

hnvn on 27 Mar 2018

Download NDK and CMake for NDK. You can do this using android studio or upload via console.

Assemble openssl and load into the appropriate folder NDK.

The hierarchy of the project has not changed much https://github.com/tdlib/td/issues/77#issuecomment-373172529
You must use the current project java. It shows an example of building the required library. You can also take from it all the necessary links for CMakeList.txt (If possible read about Boost in CMake)

Example of an assembly command
/home/user/prog/android-sdk/cmake/3.6.4111459/bin/cmake -DANDROID_ABI=armeabi-v7a -DCMAKE_BUILD_TYPE=Release -G Ninja -DCMAKE_TOOLCHAIN_FILE=/home/user/prog/android-sdk/ndk-bundle/build/cmake/android.toolchain.cmake -DANDROID_NATIVE_API_LEVEL=23 -DANDROID_TOOLCHAIN=clang -DOPENSSL_ROOT_DIR=/home/user/prog/android-sdk/ndk-bundle/platforms/android-23/arch-arm/usr/lib/armeabi-v7a/ -DOPENSSL_INCLUDE_DIR=/home/user/prog/android-sdk/ndk-bundle/platforms/android-23/arch-arm/usr/lib/include/ -DCMAKE_LIBRARY_OUTPUT_DIRECTORY=/home/user/prog/td/jnibuild/ -DTD_ENABLE_JNI=ON -DANDROID_STL=c++_static ..

Perhaps you will come across a lot of other plot events during the assembly process. Which will need to be addressed.

Let's wait for the solution of professionals.

@levlam, Can u give some hint or guide how to build TdJson lib for Android as I'm going to integrate it to a flutter project via platform channels. I want to use json interface on both iOS and Android, so I can write the same logic for both on flutter side.

aaugmentum on 9 Jun 2019

@aaugmentum
You will need two things:

Write JNI wrappers for 5 methods from TDLib JSON interface. It should be easy.
Build TDLib, including OpenSSL, and the JNI wrapper using Androind NDK. This is mostly covered by https://developer.android.com/studio/projects/configure-cmake and answers in this issue, but can take a lot of time if you have never done this before.

levlam on 9 Jun 2019

@aaugmentum This is, for example, the JNI wrapper: tdjsonjava.zip.

levlam on 9 Jun 2019

@aaugmentum Could you try these prebuilt libs:
tdlib.zip. They are supposed to contain TDLib 1.4.0 with implementation of org.drinkless.tdlib.JsonClient from the previous comment and provide TDLib's JSON interface for Android.

levlam on 10 Jun 2019

https://github.com/tdlib/td/issues/77#issuecomment-376562359

It definitely worked. Next, from the archive of Leo, you can copy the interface in Java.

There are androidx imports. You may have to transfer the project to it.

The most important thing is to openssl competently assemble.

Yeah, it worked! Thank you very much :)

The only problem was in library name in JsonClient.java.
tdjsonjava is the right name.

static {
        try {
            System.loadLibrary("tdjsonjava");
        } catch (UnsatisfiedLinkError e) {
            e.printStackTrace();
        }
}

how the funk do I add the prebuilt tdlib for android to a project? just can't find any how
still can't setup a working copy of tdlib or telegram official cllient

There are any prebuilt libs for TDLib 1.5.0?

1.5 is deprecated. Need a newer version 1.6

Also, for building android lib you can look here ktd
It's in code, but if you run it, it will also println command executed
I've used that build of openssl

whyoleg on 21 Nov 2019

But also I have a question to @levlam
I've build lib and strip it with ndk, but the size of lib is almost 2 times bigger, than prebuilt, that you provided?
What more I can do it improve lib size?

whyoleg on 21 Nov 2019

@whyoleg Here are the CMakeLists.txt files I use to build TDLib for Android: libtdjsonjava and JNI.

The key part is likely to be

string(APPEND CMAKE_CXX_FLAGS " -ffunction-sections -fdata-sections -fno-exceptions -fno-rtti")
string(APPEND CMAKE_SHARED_LINKER_FLAGS " -Wl,--gc-sections -Wl,--exclude-libs,ALL")

@levlam Big thx! It's work, cool, size even less, then in prebuilt version :)

Could you please gimme detail on how to build libtdjson for Android. I tried this guide with CMakeLists.txt above from @levlam , but to no avail.

Thanks

AndrewTran2018 on 3 Jun 2020

@levlam Can you provide me prebuilt libtdjson.so of Android with the raw interface of something like this:
td_json_client_create
td_json_client_send
...

I plan to use Dart FFI to directly invoke C functions. Thanks.

@levlam I finally get it done. But libtdjson looks big, >200M. Is that normal?

AndrewTran2018 on 6 Jun 2020

Anyway I feel fairly satisfied with this latest combo: tdLib 1.6.6 + openssl .1.1.1g

AndrewTran2018 on 6 Jun 2020

Have you stripped it?
For ARM64 the size should be 15 MB.

levlam on 6 Jun 2020

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.

levlam on 8 Jun 2020

@levlam I managed to collect it. Too bad not in Real-time.

This project may make it easy to build openssl https://github.com/KDAB/android_openssl
Wrappers also managed to assemble. For libtdjni only works after building java example in jnibuild https://github.com/tdlib/td/tree/master/example/java.

@levlam, It reminds that isopene has a sting up 14562568...

Gimme instructions on how to strip files. Thanks. @levlam

I wanna keep the same lib name and interface as the previous one. Update CMakeList.txt in libtdjsonandroid.zip? @levlam

AndrewTran2018 on 18 Jun 2020

@AndrewTran2018 You can edit provided scripts as you wish.

levlam on 18 Jun 2020

@levlam Ok, I got android libtdsjon to be stripped = 16-17M. That's nice. As for iOS build, how to strip libtdjson.dylib? It's 284M for now. That's so big. I looked at CMakeList.txt and it looks like you have put it under stripping process already, but it's still that big. Please explain this. Thanks.

AndrewTran2018 on 18 Jun 2020

iOS binaries are very big, because of their format and because they contains code for all architectures. Installed size will be much smaller that 284MB, but still times bigger than on Android.

levlam on 18 Jun 2020

Wow! Could you please help reduce its size? Many thanks @levlam

AndrewTran2018 on 19 Jun 2020

No. You can complain to Apple about binaries size on their platform.

Hi,

I'm trying to build for android, using JSON c++ interface, I've followed instructions, download libtdjsonandroid.zip and uncompress inside example folder. I can compile openssl libraries, but when I execute build-all.sh I get the error

'td/telegram/td_api.h' file not found

Any ideas? I attach the log

You need to run ./export.sh instead of ./build-all.sh. Thanks for pointing this out. I fixed the instructions.

Thanks for your quick response, now works as expected.

@i-Naji Could you set TDLib log verbosity level to 15 and send the log from app launch to @tdlib_bot in Telegram?

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.

can you advice please how can I use android json interface in project after build?

marior765 on 5 Dec 2020

@marior765 In the same way as any other shared library on Android. For libtdjsonandroid JSON interface methods will have names prefixed with undescore.

@levlam sorry for a stupid questions, but all I managed to implement is this one class, but as result its throw "No implementation found" error

tdjsonandroid doesn't define any native Java methods. If you want to use JSON interface from Java, you need to use libtdjsonjava and provided by it JsonClient class. You must not rename JsonClient class or change its package. Otherwise, the native method will not be found.
