Hi, I have a problem with LuaState.call native code…
It works but sometimes it crashes the app with the following error:

I’m using an Async Lua function that start a bluetooth discovering and, when It finish, the native environment call Lua … this is a part of my code… please help me
com.ansca.corona.CoronaRuntimeTask task = new com.ansca.corona.CoronaRuntimeTask() {
@Override
public void executeUsing(com.ansca.corona.CoronaRuntime runtime) {
// *** We are now running on the Corona runtime thread. ***
try {
// Fetch the Corona runtime’s Lua state.
com.naef.jnlua.LuaState luaState = runtime.getLuaState();
// Fetch the Lua function stored in the registry and push it to the top of the stack.
luaState.rawGet(com.naef.jnlua.LuaState.REGISTRYINDEX, luaFunctionReferenceKey);
// Remove the Lua function from the registry.
luaState.unref(com.naef.jnlua.LuaState.REGISTRYINDEX, luaFunctionReferenceKey);
mBtAdapter = BluetoothAdapter.getDefaultAdapter();
startScanBT(luaState); //luaState is used to make Call when bluetooth finish.
}
catch (Exception ex) {
ex.printStackTrace();
}
}
};
// Send the above task to the Corona runtime asynchronously.
// The send() method will do nothing if the Corona runtime is no longer available, which can
// happen if the runtime was disposed/destroyed after the user has exited the Corona activity.
dispatcher.send(task);
THE ANDROID VERSION IS 4.0.4 — PLEASE HELP ME
