Android studio 在哪里安装 NDK 文件?(以 zip 格式下载) [英] Android studio Where to install NDK file? (downloaded it in zip)

问题描述

我的安卓工作室说它想要更新.但是当我这样做时，我尝试更新它，但它不起作用，所以我不得不启动:
C:UsersusernameAppDataLocalAndroidsdk oolsandroid.bat
安装其他包.但是 NDK 文件不会更新，所以我从以下位置手动下载:

设置/检查以下环境变量也可能对您有所帮助:

NDK_HOME=C:Androidsdk
dk-bundleNDK_MODULE_PATH=C:Androidsdk
dk-bundle

额外的东西:

在执行环境变量时(SDK的大括号):

ANDROID_HOME=C:Androidsdk

对于 JDK:

JAVA_HOME=C:Program FilesJavajdk1.8.0_112JAVA_PATH=C:Program FilesJavajre1.8.0_112in

JDK 是 Java 开发工具包.
JRE 是 Java 运行时环境.

如果您 紧 使用 Gradle 的内存 (RAM)(700 兆字节大约是您所能达到的最低限度，其他工具如 monitor.bat 也使用这个变量，它无处不在)(显然你想要让它尽可能大，而不用交换它构建极其缓慢{注意下划线非常重要！[这是一个保留的名称空间冲突运算符，不要让我解释它非常复杂！]}):

_JAVA_OPTIONS=-Xmx700m

My android studio said it wanted to update. But when I did I tried to update it but it wouldn't work so I had to launch:
C:UsersusernameAppDataLocalAndroidsdk oolsandroid.bat
to install other packages. But the NDK file wouldn't update, so I manually downloaded it from:

https://developer.android.com/ndk/downloads/index.html#download

Now I have this zip file and where should I extract the folder? Grateful for any help!!

The folder name is android-ndk-r13b.

解决方案

Yes, rename the extracted folder android-ndk-r13b(probably the exact name will be outdated someday soon) to ndk-bundle (you can put the NDK [and SDK for that matter] anywhere, and leave the name alone if you want {do not do this, I'm sure seen one case of hard-coded sub-path}),
then, make the settings point to the location where you put it.

Android Studio, File menu | Project Structure Ctrl+Alt+Shift+s
(short-cut: ctrl+Alt+Shift+s):

It might also be helpful to you to set/check the following environmental variables:

NDK_HOME=C:Androidsdk
dk-bundle
NDK_MODULE_PATH=C:Androidsdk
dk-bundle

EXTRA stuff:

While were doing environmental variables (belt-and-braces for SDK):

ANDROID_HOME=C:Androidsdk

For JDK:

JAVA_HOME=C:Program FilesJavajdk1.8.0_112
JAVA_PATH=C:Program FilesJavajre1.8.0_112in

JDK is the Java Development Kit.
JRE is the Java Run-time Environment.

If your tight on memory (RAM) for Gradle (700 Megabytes is about as low as you can go, other tools like monitor.bat use this variable too, it's ubiquitous) (clearly you want to make it as big a possible, without swapping making it extremely slow to build {note the underscore VERY important ! [it's a reserved name space conflict operator, don't ask me to explain it's VERY complicated !]}):

_JAVA_OPTIONS=-Xmx700m
