Android的SDK文件夹服用大量的磁盘空间。我们是否需要保留所有的系统映像的？ [英] Android SDK folder taking a lot of disk space. Do we need to keep all of the System Images?
问题描述
有一个大量的系统映像我在Android SDK文件夹的磁盘上堆积。我几乎不使用仿真器。 6个月内可能会一次。我的大多数发展是直接在设备上。我想检查是，将删除系统映像（至少为老APIS即＆LT; 22）？影响开发
There are a lot of system images piling up on my disk in the android sdk folder. i hardly use the emulator. May be once in 6 months. Most of my development is directly on device. What i wanted to check was, will removing the system images (at least for the old APIS i.e. < 22) impact the development?
此外，谷歌API的文件夹下看到。我应该保持它的所有版本，或只是一个最新足矣？
推荐答案
在Android的SDK目录系统映像包含pre-安装的Android操作系统的映像，并且只能由仿真器使用。如果您使用真正的Android设备进行调试，您没有记录仪需要他们，你可以删除它们。
System images in Android SDK directory contain images of pre-installed Android operating systems, and are only used by emulators. If you use your real Android device for debugging, you no logger need them, you can remove them as well.

ARM: These are emulating processors with ARM architecture.
什么是目录的android-22 的呢？而为什么会有这样的 Android的 - 在系统图像目录* 目录
What is directory
android-22for? And why are there suchandroid-*directories in the system images directory?
正如你可能已经想通了为什么，每个系统的图像是一个特定的Android版本的安装，以及硬件架构。因此，我们应该有不同的Android版本的多个系统映像。
As you might already figured out the why, each system images is an installation of a particular Android version as well as a hardware architecture. So we should have multiple system images for different Android versions.
我可以在删除系统映像？
Am I allowed to remove system images?
总之，是的。但是，删除它们后，您将不再能够使用仿真器。但你仍然可以使用真正的Android设备没有任何问题。
In short, Yes. But after removing them, you are no longer able to use emulators. But you can still use your real Android device without any issues.
