It seems to be your issue.

Can you give more context on your setup ? What does
file /home/wmlab/Android/Sdk/ndk/20.0.5594570/toolchains/llvm/prebuilt/linux-x86_64/lib/gcc/x86_64-linux-android/4.9.x/…/…/…/…/x86_64-linux-android/bin/ld: error: …/…/…/…/libs/x86_64/libdeepspeech.so

Thanks for reply.
![:slight_smile:](

My setup is ubuntu16.04 LTS slash
I use swig 3.0.12 and I put the libdeepspeech.so which is from the
native_client.arm64.cpu.linux.tar.xz of 0.5.1 release, into three
directories (/native
client/java/libdeepspeech/libs/{arm64-v8a,armeabi-v7a, x86_64} ) slash
I think the Android/Sdk directory was generated by Android studio.

By the way, I type in the instruction 'file

You need to download each arch, they are different binaries. If you put
ARM64 into those three directories, then no surprise.

Thanks for reply again.

I finally put libdeepspeech.so from
'native_client.arm64.cpu.android.tar.xz' to '/native
client/java/libdeepspeech/libs/arm64-v8a', slash
libdeepspeech.so from 'native_client.amd64.cpu.linux.tar.xz' to '/native
client/java/libdeepspeech/libs/x86_64', slash
libdeepspeech.so from 'native_client.armv7.cpu.android.tar.xz' to
'/native client/java/libdeepspeech/libs/armeabi-v7a',

so finally it build successful, and I got an .apk file in '/native
client/java/app/build/outputs/apk/release/app-0.6.0-alpha.5-release-unsigned.apk'

I have not test the apk file, but I will do it as soon as possible. slash
If some error comes out while testing apk on my android device, i will
post it on this forum.

Thank you very
much.![:smiley:](

I'm surprised that you got tricked, if you can identify what is unclear
in the current documentation, please send a PR to improve it.

Could you give me the apk download if you don't mind?

Wow, i'm surprise that someone still want to use this solution. slash
But unfortunately i give up at the end. (I think i successfully install
it on an android phone, and run successfully, but i fail to train a good
mandarin model, so this solution doesn't work for me) slash
And i left my lab too (a year ago...), so the apk file may be lost, i
feel sorry. slash
But if you are looking forward to build a STT APP to android, i finally
use CMU Sphinx to finish my school project, maybe it will help. slash
good luck

Have you tried this

to build your own?

I was actually trying to find an stt app for English( and if fortunate
enough Bangla). But after trying to build Mozilla deep speech and
failing, I have hit a roadblock. So I was trying to find an apk from
others.

Sorry, DeepSpeech is not an end user product. You could use the 0.8
tflite model to create your own app though. But you have to compile
yourself.

What part of the example do you have problems with? I find it quite self
explanatory if you have some experience building apps. If not, again,
this is not for end users.
