My plugin does not work in solar2d Android Native

[GamingStudio17]

Hi, I’m trying to make my java plugin in solar2d, but I can’t get the standard example working.

I open in Android Studio a standard example from solar2d: Native folder -> Project Template -> App -> android
The main.lua file in the Corona folder:

local library = require "plugin.library"

-- This event is dispatched to the global Runtime object
-- by `didLoadMain:` in MyCoronaDelegate.mm
local function delegateListener( event )
	native.showAlert(
		"Event dispatched from `didLoadMain:`",
		"of type: " .. tostring( event.name ),
		{ "OK" } )
end
Runtime:addEventListener( "delegate", delegateListener )

-- This event is dispatched to the following Lua function
-- by PluginLibrary::show() in PluginLibrary.mm
local function listener( event )
	print( "Received event from Library plugin (" .. event.name .. "): ", event.message )
end

library.init( listener )

local object = display.newRect( 100,100,50,50 )
 
local function onObjectTouch( event )
    if ( event.phase == "ended" ) then
        library.show( "corona" )
        print("TEST",library.show( "corona" ))
    end
    return true
end
object:addEventListener( "touch", onObjectTouch )

When you click on the white square, this code calls the show function from the java plugin and print:

“Hello!”

and

“TEST” “Hello!”

When running and building in Android Studio, the plugin works.

Next, I want to make a plugin for Corona Simulator.
Using the instructions: https://www.qweb.co.uk/blog/creating-a-corona-native-plugin-with-android-studio

I create plugin-release.aar, and extract classes.jar, rename it to plugin.library.jar.

Next, create metadata.lua and move it all to the data folder. In the end, I get the following: Then I compress the resulting folder in gzip and get the data.tgz plugin ready!

build.settings:

settings = 
{
	splashScreen = 
    {
        enable = false
    },
     plugins =
    {
        ["plugin.library"] =
        {
          publisherId = "com.coronalabs",
          supportedPlatforms = { android=true }
        },
    },    

	iphone =
	{
		xcassets = "Images.xcassets",
		plist =
		{
			UILaunchStoryboardName = "LaunchScreen",
		},
	},
}

I copy this to: /Users/user_name/Solar2DPlugins/com.coronalabs/plugin.library/android I make the assembly in solar2d 2020.3594. the assembly passes without errors, when I start Corona Test.apk on the device, I immediately get errors:

What am I doing wrong? How to make your own plugin for solar2d?

[GamingStudio17]

You can make the test easier:
LuaLoader code:

package plugin.library;

import android.webkit.WebView;
import android.webkit.WebViewClient;

import com.ansca.corona.CoronaActivity;
import com.ansca.corona.CoronaEnvironment;
import com.ansca.corona.CoronaLua;
import com.ansca.corona.CoronaRuntime;
import com.ansca.corona.CoronaRuntimeListener;
import com.ansca.corona.CoronaRuntimeTask;
import com.ansca.corona.CoronaRuntimeTaskDispatcher;
import com.naef.jnlua.JavaFunction;
import com.naef.jnlua.LuaState;
import com.naef.jnlua.NamedJavaFunction;
import android.util.Log;

@SuppressWarnings(“WeakerAccess”)
public class LuaLoader implements JavaFunction{
@Override
public int invoke(LuaState luaState) {
Log.d(“Corona native”, “Lua Loader invoke called”);
return 0;
}
}

main.lua code:

local plugin = require(“plugin.library”)
print(“test:”, plugin)

In build on Android Studio get print - true
In build simulator the same error that I described above

How to make my plugin work? Why does it work with standard plugins?

As I suggested in this topic:

Android Native... need up-to-date tutorial/help

Could someone p-p-p-p-please do a youtube how-to video (or step-by-step blog) on setting up a new project that uses android native components. E.g. I’d like to send/recv intents to/from another android app (e.g. tasker <-> corona). The docs are pretty confusing and sparse and seem to focus on ios native - not android. This tool would be even more awesome if it could easily hook into native android.

Hopefully someone will come up with an indepth how-to starter-guide for android native!

[GamingStudio17]

I realized what the problem is! It all worked!
I did not compress the plugin correctly in the archive. Squeezing the plugin through the console as it is written here https://docs.coronalabs.com/native/hostedPlugin.html it worked!

[GamingStudio17]

What’s up in recent builds? Native plugins are no longer added to the assembly and do not work

[GamingStudio17]

Has anyone managed to use a custom native plugin in a recent build?

[GamingStudio17]

I understood what the problem is. It says here: https://docs.coronalabs.com/native/android/index.html
libs / - This is where third-party (Corona) .jar plugins that your app relies upon should go.

In recent Solar 2D versions, when compiling .jar files from this folder are not added to classes.dex. Please correct, in 3594 everything works correctly
