If I just want to use js module but not other. I can compile myself v8, how can I do？

[ericwlange]

As mentioned in README.md:

The Node.js library (libnode.so) is pre-compiled and included in binary form in LiquidCoreAndroid/jni/lib/**/libnode.so, where ** represents the ABI. All of the modifications required to produce the library are included in deps/node-6.10.2. To build each library (if you so choose), you can do the following:

.../LiquidCore/deps/node-6.10.2% ./android-configure /path/to/android/ndk <abi>
.../LiquidCore/deps/node-6.10.2% make

where <abi> is one of arm, arm64, x86 or x86_64

You can include libnode.so in your project. It includes the V8 library (as well as node, but node is actually quite small -- the bulk of library is V8)

libnode is too big~~ I just want v8 java bridger......

[ericwlange]

Yup. V8 is big. The vast majoroty of node is V8.

If you are looking for just a bridge to the V8 installed on the device, I don't think it will work. I looked into this in the past. You never know which version is on any given device. The API changes constantly. You have to install your own version, which is what is in libnode.

I compile myself v8 for android only 7 ~8MB size， So how can I use your code link with myself compiled v8. I just want to a bridge with java and v8. So how can I do this ?

[ericwlange]

My library includes a copy for 4 different architectures: armv7, arm64, x86 and x86_64. See the other open issue for a discussion.

yes It include too much things， I just want to the part of bridge

[ericwlange]

It is interesting. Here is a list of the generated static libraries:

None of those libraries are very big. And even when I look at the node object files, it doesn't explain why the final .so is so big:

I will look into this. But if you just want to use the v8 libraries, follow the directions to build node, but only use the .a libraries. See if that will work.

[ericwlange]

Ok. I just discovered that libnode.so contains all debugging symbols. That's why the file is bloated. arm-linux-androideabi-objdump --debugging lib.target/libnode.so > /var/tmp/foo.foo produced a 61 MB file!

I will figure out the flag to turn that off for the release version. As it happens, those debugging symbols have been very useful to me for, well, debugging. But I will thin out the release version.

But I Just want to use only V8 without libuv and others. How can I do it?

[ericwlange]

I don't know. That's not what this project is about.
