Cannot compile Android plugin

amaximov

I've been trying to make a plugin to access device identifiers and finished iOS plugin really fast, but Android has been a struggle for several hours. I followed @ar2rsawseen 's tutorial on AppCodingEasy but was not able to get things to work properly. I then looked at the plugin sources in the Gideros installation and did some minor tweaks to my identifier.cpp but still got NDK errors (Attached).

Here is my bare-bones attempt at just getting a successful build.
identifier.cpp:

#include "gideros.h"
#include "lua.h"
#include "lauxlib.h"

static const char* pluginName = "identifier";
static const char* pluginVersion = "1.0";
/*static const char* javaClassName = "com/giderosmobile/android/ExamplePlugin";

// Store Java Environment reference
static JNIEnv *ENV;
// Store our main class, what we will use as plugin
static jclass cls;*/

// Here we register all functions we could call from lua
static const struct luaL_Reg funcs[] = {
{ NULL, NULL } //Don't forget nulls at the end
};

// Here we register all the C functions for lua so lua engine would know they exists
static int luaopen_plugin(lua_State *L)
{
luaL_register(L, pluginName, funcs);
return 1;
}

//here we do all our stuff needs to be done on initialization
static void g_initializePlugin(lua_State *L)
{
// Get java environment reference
//ENV = g_getJNIEnv();

// Get global package object
lua_getglobal(L, "package");
lua_getfield(L, -1, "preload");

// Put our plugin name inside with a callback to registering C functions
lua_pushcfunction(L, luaopen_plugin);
lua_setfield(L, -2, pluginName);

lua_pop(L, 2);
}

// And here we free everything we need to free
static void g_deinitializePlugin(lua_State *L)
{

}

// Register our plugin with Gideros lib
REGISTER_PLUGIN(pluginName, pluginVersion)

Android.mk:

LOCAL_PATH := $(call my-dir)

Ok so I tried using flurry source files as a template and now things work. I'm still not sure why my original code from AppCodingEasy tutorial didn't work. Perhaps internal changes in Gideros were the problem?

Yes most probably there were internal changes, in the latest versions lots of internals was changed
