lua-for-android's Introduction

General

This is a friendly and high performance bridge for java and lua in android. With it, you can call java functions, use java objects easily in lua. It supports auto method deduction, auto data conversion, import java package/class, multi-thread, exception handling, class extension/implementation and other facilitative features. See wiki for more detailed description.

Module luaffi, luasec, luasocket are optional package. And module lfs is embeded.

Both lua(5.1-5.3) and luajit(2.0.5 and 2.1.0-beta3) are supported.

Configure Android.mk by setting LUA_LIB :=(lua or luajit) to choose the proper version.

Currently, lua 5.3.5 is in lua dir and luajit 2.1.0 beta-3 is in luajit dir.

Load the lib by LibLoader.java in the module app or add System.loadLibrary("luadroid.so") to your code.

Module lib is the true library that you can embedded into your code.

Module app is a lua editor for running test in android.

Module luaffi is the ffi lib for luadroid to invoke c apis, and it requires luadroid.so to be statically linked

Performance

Under release mode, the bridge around 3+ times slower than jni because of consumption in method deduction and data conversion. Yet, if no argument provided, it is almost as fast as jni.

Around 2500000 method call(Math.abs) per second on my Oneplus 5 device. Around 1800000 member access plus with method call(Math.abs) per second. Note that if you run it in debug mode,CheckJni mode is enabled by the vm,and it will take away more than half of the efficiency.

Here is the test script:

using "java.lang"
--for method call test
local abs=Math.abs
local t=os.clock()
for i=1,2.5e6 do
    abs(0)
end
print(os.clock()-t)

--for member access test
t=os.clock()
for i=1,1.8e6 do
    Math.abs(0)
end
print(os.clock()-t)

怎么导入你的项目到我的项目里呢

App form assets crashes when trying to run on android 11

App instantly crashes without any messages about error

How to import/use static inner class

How to import or use static inner class like android.view.ViewGroup.LayoutParams

I have try:

import "android.view.ViewGroup.LayoutParams"
-- showing error like "no static field LayoutParams"

import "android.view.ViewGroup$LayoutParams"
-- showing error like "error field ... ViewGroup$LayoutParams"

import "android.view.ViewGroup"
print(ViewGroup.LayoutParams)
-- showing error like "no static field LayoutParams"

There is an update from LuaJIT missing

Hello !
In file dasm_x86.lua there is an update from LuaJIT missing:

  vroundpd_3 =	"rmioy:660F3AV09rMU",
  vroundps_3 =	"rmioy:660F3AV08rMU",

Is now in LuaJIT:

  vroundpd_3 =	"rmioy:660F3Au09rMU",
  vroundps_3 =	"rmioy:660F3Au08rMU",

Cheers !

Now there is an error with meta methods

Hello !
Thanks for fix the issues reported before.
But now with the changes you've made to the meta methods it compiles fine when applied to the original lua-ffi but when try to test it "lua test.lua" we get this error:

ljs: test.ljs:685: type struct vls has no member key
stack traceback:
	[C]: in metamethod '__index'
	test.ljs:685: in main chunk
	[C]: in ?

Note I'm using it with https://github.com/mingodad/ljs but otherwise it's the same in Lua. And it was working before the latest changes.

Cheers !

ide support js language comment ?

Is it possible to import Sikuli functions?

If so, how?

Also, how can I build it?

当lua代码出现死循环我该怎么停止运行这个时候button没有反应

Failed to resolve: luadroid:dexmaker:unspecified

I got this error message.

Code formating

Hello !
I've noticed that you did some code reformatting on some dynasm files making it a bit hard to see what you've changed when comparing with LuaJIT, was it intentional ?
Do you plan to submit your changes back to LuaJIT or your changes are only specific to use with Lua ?
Cheers !

Is it possible to create an NDK app using luadroid.so?

Error on arm32

Hello !
Testing your project with with the apk on android arm32 (nexus7) this program fail:

local ffi = require('ffi')
local buf = ffi.new('char[256]')
local c = ffi.C
ffi.cdef('int sprintf(char *buf, const char *fmt, ...);')
print(c.sprintf(buf, '%g', 5.3), ffi.string(buf));

Expected:

3    5.3

Output:

11   2.14609e+41

The above and the following are from the original test.lua and it also fail the following with segfault:

-- unsigned should be ignored for pointer rules
ffi.cdef([=[
int strncmp(const signed char *s1, const unsigned char *s2, size_t n);
]=]);
assert(ffi.C.strncmp("two", "three", 3) ~= 0); -- segfault here
...
-- Test io.tmpfile()
ffi.cdef ([=[
    int fprintf ( FILE * stream, const char * format, ... );
]=]);
local f = io.tmpfile();
ffi.C.fprintf(f, "test: %s\n", "foo"); -- segfault here

f:seek("set", 0);
local str = f:read('*l');
assert(str == 'test: foo', str);
f:close();

Commenting the above mentioned tests all the rest of test.lua pass.
Great work !
