Features​
Lua scripting
Simple and intuitive hook API
Share your package with others by publish it at WeiJu2-Scripts
Q&A​How to write a hook?​
Code:
local Toast = import("android.widget.Toast")
local Activity = import("android.app.Activity")
local Bundle = import("android.os.Bundle")
local StringBuilder = import("java.lang.StringBuilder")
hook {
class = Activity,
returns = void,
method = "onCreate",
params = {
Bundle
},
after = function(this, params)
-- This will call the `StringBuilder(CharSequence seq)` constructor
-- to instantiate a StringBuilder object
local sb = StringBuilder("Hello, ")
sb:append("WeiJu2")
Toast:makeText(this, sb:toString(), Toast.LENGTH_SHORT):show()
-- ^
-- Note: `this` is the Activity instance
end,
}
How to modify class fields?​
Code:
-- With the `import` function you can bind any java class, and access all the fields and methods that defined
-- in that class. No more `XposedHelper.setStaticObjectField(Build.class, "DEVICE", "coral")` much cleaner!
local Build = import("android.os.Build")
Build.DEVICE = "coral"
Build.PRODUCT = "coral"
Build.MODEL = "Google Pixel 4XL"
Build.BRAND = "google"
Build.MANUFACTURER = "google"
Build.VERSION.RELEASE = "13"
How to import a package?​
Code:
require("ikws4.system_variable").setup {
-- configs goes here
}
How to create a package?​
A basic package template:
Code:
--[[
@metadata
return {
name = "my_package",
author = "you",
version = "1.0.0",
description = "Describle your package"
}
@end
--]]
local config = {
}
local M = {}
M.setup = function(opts)
config = table.extend(config, opts or {})
end
return M

Hi @zhipingne
Since from what i understand, it is possible to inject Lua code via Xposed with your application, in your opinion would it be possible to act on all applications embedding web browsers to navigate on web pages adapted to mobiles?
Example: inject CSS rules globally on all user applications to affect some like Spotify, Discord, Teams and others?
If it's possible I'll have fun!

Sorry for the late response, I was experiment a way to inject custom css into WebView in the last two days, And finally got a working demo. (It took so mush time because of the `object` function, in order to proxy a concrete class we need to generate dex file at runtime lol)
FYI, I followed this article: https://medium.com/@fanisveizis/usi...d-js-scripts-on-android-webviews-6da0502d6595
UPDATE
It stop working... The `dex` file that generate at runtime does not loaded back properly in the next launch time.

Ok, do you think it is possible to achieve something functional in the end?
I would be very interested.
Thx

When i think about it, in fact your module can become as powerful as substratum if we want?

Code:
{
"builtin": false,
"collection": "Privacy",
"group": "Use.Tracking",
"name": "DeviceIntegrityCheck\/checkIntegrity",
"author": "B!",
"version": 0,
"description": "Skip asitplus device integrity check",
"className": "at.asitplus.utils.deviceintegrity.DeviceIntegrityCheck",
"methodName": "checkIntegrity",
"parameterTypes": [],
"returnType": "void",
"minSdk": 1,
"maxSdk": 999,
"minApk": 0,
"maxApk": 2147483647,
"enabled": true,
"optional": false,
"usage": true,
"notify": false,
"luaScript": "function before(hook, param)\n param:setResult(nil)\n return true\nend\n"
}
(Thanks to B!GBOY)
Is it possible to run such a XPrivacyLua script? If so, how formatted?

Maybe, I can write a convertor for this.

What do you mean not available? Is it can not be downloaded?
If so, here is the google drive link https://drive.google.com/file/d/1upurJDTJ5nS3RodsqLTCJKFg9daN4EaH/view?usp=sharing

Thank you for this module, it looks awesome! Do you think it would be possible to use it to implement java code, such as a java script to disable the elastic overscroll in Android 12+? There is an example in java located here that I would like to test.

Yes, you can translate java code in to WeiJu2 scripts, here is an example:
Code:
local BridgeActivity = import("com.getcapacitor.BridgeActivity")
hook {
class = BridgeActivity,
returns = void,
method = "onStart",
after = function(this, params)
local webview = this:getBridge():getWebView();
webview:setOverScrollMode(webview.OVER_SCROLL_NEVER);
end
}
Note: I did't test the code, it just an example to show it's possible to implement java code using WeiJu2 hook.
UPDATE
How to disable Programmatically Android 12 Elastic Scroll Animation
how can I turn off the elastic scroll effect that comes with android 12? Best regards

I think this code will make all view non over scrollable.
Code:
local View = import("android.view.View")
hook {
class = View,
returns = void,
method = "setOverScrollMode",
before = function(this, params)
local OVER_SCROLL_NEVER = 2
params[1] = OVER_SCROLL_NEVER
end
}

Thank you for the reply. That's awesome to hear. I'm going to keep messing around with it to see if I can disable the overscroll then. The code that you provided unfortunately doesn't work for all apps. It does work for some however. I believe there is another hook somewhere that must be disabled as well. If you have any ideas they would be greatly appreciated.
Thank you again for the app. It's amazing!

Try this to see if it works
Code:
local View = import "android.view.View"
local OVER_SCROLL_NEVER = 2
hook {
class = View,
params = {
Context,
AttributeSet,
int,
},
after = function(this, params)
this.mOverScrollMode = OVER_SCROLL_NEVER
end,
}
hook {
class = View,
returns = void,
method = "setOverScrollMode",
before = function(this, params)
params[1] = OVER_SCROLL_NEVER
end,
}

Thank you for the attempt, but unfortunately, that doesn't seem to fix it either. I've asked multiple developers to see if they could sort it and nobody has been able to so far. I don't know how Google implemented it so deep, but it seems very difficult to remove the "accordion" scroll. Thank you for trying though. If you have any ideas though, they would be greatly appreciated.

Thanks! The apk isn't posted on the first post or on github.
This does seem like a replacement for XprivacyLua which just stopped being supported.

---

It work perfectly! Thank you very much.
One more thing, Is there a way we can load script from local file instead of write directly on module interface, please?

File access causes me a lot of headache, and current implementation still have some flaw it.
Why would want load script from file?
