Android studio Where to install NDK file? (downloaded it in zip)
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:\Users\username\AppData\Local\Android\sdk\tools\android.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.
Answer
Yes, rename the extracted folder android-ndk-r13b(probably the exact name will be outdated someday soon) to ndk-bundle (you can put the NDK [and SDK for that matter] anywhere, and leave the name alone if you want {do not do this, I'm sure seen one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:\Android\sdk\ndk-bundle
NDK_MODULE_PATH=C:\Android\sdk\ndk-bundle
EXTRA stuff:
While were doing environmental variables (belt-and-braces for SDK):
ANDROID_HOME=C:\Android\sdk
For JDK:
JAVA_HOME=C:\Program Files\Java\jdk1.8.0_112
JAVA_PATH=C:\Program Files\Java\jre1.8.0_112\bin
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
