Android 应用程序加载时间过长

Question

我有带有活动和片段的 android 应用程序。 它还包括 firebase 和 GoogleMaps。

在我的 Nexus 5 设备上构建和运行应用程序后，应用程序活动需要很长时间才能加载。

我试图通过检查时间滞后并消除预加载中的许多滞后来进行跟踪。 但我并没有完全成功。

我的问题是：如何删除更多操作，即加载几秒钟

感谢所有答案！

Answer 1

您的应用在模拟器上或调试时始终运行速度较慢。在实际设备上安装aseyapp。您会很好的。希望这会有所帮助

Answer 2

在我的情况下，当我在模拟器上运行我的应用程序时，每次在启动屏幕之前显示白屏。 但在Play商店发布后。 这个问题完成。
