从启动到结束OnCreate浪费时间

Question

我正在开发一款休闲游戏。 我很无聊，等到我的应用程序还没有活着，我可以玩，所以我试图减少所有的浪费时间：我用OnCreate中的线程启动了一个启动画面;我为某些init使用了AsyncTask。 然而，读取logcat之前，我看到在OnCreate开始的第一条指令（即调用splashscreen线程）之前，我已经浪费了将近6秒钟，我不知道为什么......

任何线索？我怎样才能加快我的应用程序的开始？

感谢您的回复！

Answer 1

步骤＃1：不要做设备的性能测试将各种废话运行。尽管垃圾正在启动和停止，但它正在从您的应用中窃取CPU周期，这是您无法在应用程序级别进行控制或预测的方式。做一个干净的设备的性能测试，你可以管理 - 没有应用程序的小部件，没有运行的后台服务，没有安装其他应用程序等。

步骤2：不要在调试器中运行时进行性能测试。

话虽这么说...

在04-25 20:06:44.733，机器人开始启动活动。在04-25 20:06:45.023，您的应用程序的过程已开始。那一秒钟是由于其他的东西与你的设备。

在04-25 20:06:45.023和04-25 20:06:47.703之间 - 差不多3秒 - 我看到一堆看起来与您的广告提供商相关的内容。暂时禁用它并查看性能是否提高。如果确实如此，请联系您的广告技术提供商（显然是Greystripe）。

BTW，04-25 20:06:44.733是04-25 20:06:48.833前约4秒，而不是6
