How to prevent multiple Dialog instance being created so that I can cleanly dismiss()?

I have the Bluetooth callback that is sometimes triggering twice and makes handling the dialog instance difficult to dismiss().

I am declaring the Loader instance in Global

LoaderProgress mLConnectdialogLoader = new LoaderProgress(InsoleConnection.this);

I trigger the dialog called "Connecting.." for 5 seconds and then dismiss.

new Handler().postDelayed(new Runnable() {

                    @Override
                    public void run() {
                    mLConnectdialogLoader.dismiss()
                    }
  },5000);
  mLConnectdialogLoader.show("Connecting...")

How to prevent the same instance being called twice so that I can avoid having the hard time in dismissing the dialog.

just create a bool and check its status:

boolean isShown=false;   

 new Handler().postDelayed(new Runnable() {

                        @Override
                        public void run() {
                        mLConnectdialogLoader.dismiss();
                        isShown=false;
                        }
      },5000);

    if(!isShown){
    mLConnectdialogLoader.show("Connecting...");
    isShown= true;
    }

if(!mLConnectdialogLoader.isShowing())
      mLConnectdialogLoader.show("Connecting...")

In your DialogLoader class:

public boolean isShowing() { return dialog.isShowing(); }
