  • Creator 版本:2.2.0

  • 目标平台: Android


  • 详细报错信息,包含调用堆栈:

打开游戏,触发音效,切到后台,过滤"wake lock"的信息:

     1. 手机开启USB调试;
     2. 安装demo.apk;
     3. 打开游戏,点击按钮播放音效,切到后台即可;
     4. 在android studio的logcat中搜索wake lock,或cmd执行adb shell dumpsys power --charged 搜索wake lock;
         可以看到一个关于'AudioMix'的PARTIAL_WAKE_LOCK长期没有被释放。

  • 之前哪个版本是正常的 :无。首次使用2.2.0打包,未使用过其他版本。

  • 出现概率:demo必现。


  • 额外线索:

该问题最早在google play console中Android vitals被统计到,超过0.1%的出现阈值就会提示存在Stuck partial wake locks (background)的不良行为,直接影响在应用的搜索排名,如图

cocos2dx论坛中有类似发帖,但并未解决问题:
