Android O 或者 P Launcher3 Change icon shapes 功能
App Icon Shape setting missing in Android P?
Entered into the beta program for Android P and it looks like the setting for the app icon shapes has disappeared for me. Anyone else run into this issue?
No it's not missing; just enable developer options, no need to change anything in it, just enable it and the change icon shape will be available in the launcher options
在Launcher 的Home Setting 里面你会发现 Change icon shapes 有的时候能够看到，有的时候又看不到这个功能，
下面让我们来开启 Change icon shapes 功能；
首先需要在手机里面打开 开发者模式；
进入设置-》系统-》关于手机-》Build number
连线点击4次 Build number， 就会启动开发者模式；
Turn on Developer Mode (tap Build number 4 times in a row)
在桌面长按空白处
选择Home Settings
选择Change icon shape
在Android 8.0 O 或者更高的版本， 在你去桌面设置，修改图标形状之前，你可能 需要重启手机。在Android 9 P, 你不需要重启手机，但是你需要退出设置，在你的桌面设置出现之前
In Android 8.0 Oreo and above, you may need to Restart your Essential Phone before you see the option in Home Settings to change your icon shape. In Android 9 Pie, you don't have to restart your phone, but you may need to quit the Settings app before the option appears in your Home Settings.
And to change icons back to their original shape, select Use system default. If an app icon doesn't change—or has a new frame around it—the developer of that app hasn't provided different shape options.
