How to use the android demo

Deep Speech
#1

I got some error, while using “make apk” instruction.

How can I fix it?
thanks a lot.

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 returns ?

#3

Thanks for reply. :slight_smile:

My setup is ubuntu16.04 LTS
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} )
I think the Android/Sdk directory was generated by Android studio.

By the way, I type in the instruction “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” and got some message below.

Thank you very much.

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

#5

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”,
libdeepspeech.so from “native_client.amd64.cpu.linux.tar.xz” to “/native client/java/libdeepspeech/libs/x86_64”,
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.
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.
