Android and EasyNDK

@expose wrote:

I'm using cocos2d-x 3.10 and EasyNDKHelper https://github.com/alfonsocejudo/EasyNDK-for-cocos2dx3 My game is using microphone to read volume of speech and use that value to alter CCSprite SpriteFrame mouth of the character.
I'm testing sprite update condition every 0.08 second and if condition is met i'm sending message to cocos like this:

            Cocos2dxGLSurfaceView.getInstance().queueEvent(new Runnable() {
                @Override
                public void run() {
                    int delay = 80; //milliseconds
                    audioCallbackHandler.postDelayed(lipsyncRunnable, delay);
                }
            });

and lipsyncRunnable looks like this:

**        lipsyncRunnable = new Runnable() {
            @Override
            public void run() {
                    float peak = getLipsyncValue();
                            JSONObject message = new JSONObject();
                            try {
                                message.put("type","lipsync");
                                message.put("status",true);
                                message.put("peak",peak);
                            } catch (JSONException e) {
                                e.printStackTrace();
                            }
                            AndroidNDKHelper.SendMessageWithParameters("newLipsyncValue", message);
                            audioCallbackHandler.postDelayed(lipsyncRunnable, 80);
                }
                }
            }
        };

Everything works but occasionally(quite often) i get runtime errors:

I also tried to use this.runOnGLThread instead queueEvent but with no luck.

What could be wrong here? My guess is that the CCSprite has not yet updated CCSpriteFrame and the software wants to update it again which is causing some kind of race condition. Is there a way to prevent it?
