Gradle, Android and the ANDROID_HOME SDK location

问题:

edit: (aug-2016)

That question is from November 2013 (while Android Studio was still in Developer Preview mode),

Currently (AS v2.2, Aug-2016) during instalation AS asks to choose the SDK folder (or install on their default) and it automatically applies to which ever project you're opening.

That means any possible workaround or fix is irrelevant as the issue is not reproducible anymore.

original question:

we have this project with several modules that is already configured and executes correctly on another developer PC using a wrapper. I cloned the complete git submodules into my machine.

Below it's a directly print of my command line:

$ ./gradlew

FAILURE: Build failed with an exception.

* Where:
Build file '/home/budius/project_name/ActionBar-PullToRefresh/library/build.gradle' line: 1

* What went wrong:
A problem occurred evaluating project ':ActionBar-PullToRefresh:library'.
> SDK location not found. Define location with sdk.dir in the local.properties file or with an ANDROID_HOME environment variable.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

Total time: 6.378 secs

$ echo $ANDROID_HOME
/home/budius/Applications/android-studio/sdk
$ 

so, as you can see the ANDROID_HOME is there. What else do they want? What's wrong here.

running on Ubuntu 13.04

edit:

I already created a local.properties file with sdk.dir=<path> on the project root and it works. But that makes the code harder to port across systems n build server, so the question is still open.

Anyone knows why the ANDROID_HOME is not working and what to do to make it work?

回答1:

I've solved the problem. This works for me:

In

/my_current_project/

I've created a file called local.properties and put inside

sdk.dir=/my_current_path_to/sdk

In the console I need to do

set ANDROID_HOME=/my_current_path_to/sdk

Hope this helps.

回答2:

On OSX, IntelliJ won't pick up the environment variables you set in your .bash_profile or .bash_rc etc...

Try this, substituting the value of your own sdk location:

launchctl setenv ANDROID_HOME /usr/local/opt/android-sdk

Then restart IntelliJ and Bob's your uncle.

Here is a reference to the problem, stated more generally: https://emmanuelbernard.com/blog/2012/05/09/setting-global-variables-intellij/

回答3:

In my case settings.gradle was missing.

Save the file and put it at the top level folder in your project, even you can copy from another project too.

Screenshot reference:

Hope this would save your time.

回答4:

This works for me:

$ export ANDROID_HOME=/path_to_sdk/
$ ./gradlew

回答5:

The Android Gradle plugin is still in beta and this may simply be a bug. For me, setting ANDROID_HOME works, but we may be on different versions (please try again with the most recent version and let me know if it works or not).

It's also worth setting the environment variable ANDROID_SDK as well as ANDROID_HOME.

I have seen issues with this on some machines, so we do create local.properties in those cases - I have also noticed that the latest version of Android Studio will create this file for you and fill in the sdk.dir property.

Note that you shouldn't check local.properties into version control, we have added it to our gitignore so that it doesn't interfere with porting the code across systems which you rightfully identified as a potential problem.

回答6:

For whatever reason, the gradle script is not picking up the value of ANDROID_HOME from the environment. Try specifying it on the command line explicitly

$ ANDROID_HOME=<sdk location> ./gradlew

回答7:

I faced the same issue, though I had local.properties file in my main module, and ANDROID_HOME environment variable set at system level.

What fixed this problem was when I copied the local.properties file which was in my main project module to the root of the whole project (i.e the directory parent to your main module)

Try copying the local.properties file inside modules and the root directory. Should work.

回答8:

I came across the same problem when opening a cloned git repository. The local.properties file is automatically added to the .gitignore file as it is specific to the build environment of each machine and is therefore not part of the repo.

The solution is to import the project instead of just opening it after you have cloned it from git, this forces android studio to create the local.properties file specific to your machine:

File >> Import Project >>

MAC OSX:

1. Open up Terminal and edit the file:

~/.bash_profile

to add:

export ANDROID_HOME=~/Library/Android/sdk export PATH=${PATH}:${ANDROID_HOME}/tools export PATH=${PATH}:${ANDROID_HOME}/platform-tools

2. Run:

   source ~/.bash_profile

3. Restart the Terminal and Android Studio

回答10:

How to do it on MAC OSX:

1) Open up Terminal, and Edit: vi ~/.bash_profile If there is no file there, just add it.

2) Add (Change to YOUR USER NAME and add this):

#Java var home: JAVA_HOME="/usr/libexec/java_home" ANDROID_HOME="/Users/<YOUR USER NAME>/Library/Android/sdk"

3) Run source ~/.bash_profile.

4) Run echo $JAVA_HOME; echo $ANDROID_HOME;

5) If your output is:

/usr/libexec/java_home /Users/<YOUR USER NAME>/Library/Android/sdk

So you are good.

and RESTART android studio!

And, Make sure that you have java :)

java -version

And gradle :)

gradle --version

回答11:

Copy the local.properties to root folder and run again.

回答12:

This worked for me (Ubuntu):

Add ANDROID_HOME=/path/to/android-sdk to /etc/environment.

Reboot.

回答13:

in windows, I set ANDROID_HOME=E:\android\adt-bundle-windows-x86_64-20131030\sdk Then it works as expect.

When in Linux, you need to set sdk.dir.

The script uses two different variables.

回答14:

I have the same problem, seems the sample code can not find the android environment, instead to try to fix that I just remove the sample code from settings.gradle and then the installation goes fine.

after that just import the project in eclipse and that's all :)

回答15:

In Linux, try to run studio.sh from a terminal and set the ANDROID_HOME in this terminal. This worked for me.

回答16:

If you are using windows plantform, please try run Android Studio as Administrator

回答17:

Just delete the sdk.dir inside the local.preoperties file and set the ANDROID_HOME environment variable . It worked for me.

回答18:

export ANDROID_HOME=/xxx/xxx/ in shell, then use it by System.env.ANDROID_HOME in gradle file.

PS: don't forget the 'export' keywords to make the ANDROID_HOME global.

回答19:

Your local.properties file might be missing. If so add a file named 'local.properties' inside /local.properties and provide the sdk location as following.

sdk.dir=C:\Users\\AppData\Local\Android\Sdk

回答20:

I have just solved the exact same issue by adding the ANDROID_HOME as a system wide variable. In Ubuntu it should be in /etc/profile or in a shell script file in /etc/profile.d/

Then logout and login again, now Gradle should recognize the ANDROID_HOME variable.

回答21:

I came across a similar problem. Somehow, I did not have a build folder in my project. By copying this folder from another project to my project I was having an issue with, this fixed this problem.

回答22:

Installing Build-Tools 23.0.1 instead of 23.0.2 fixed this issue for me.

回答23:

solutions:

1 add "sdk.dir=path_of_sdk"

2 execute gradlew with evn variable like following:

$ANDROID_HOME=path_of_sdk ./gradlw

回答24:

You said that versioning local.properties creates problems for you. I've hacked together a script which uses android command line tool to refresh the local.properties file across the machines that are involved in the production. The android update project command, besides the local.properties produces a lot of unwanted trash (at least for me) which is the reason for all those rm commands at the end of the script.

#!/bin/bash
scname="$0"
echo "${scname}: updating local properties..."
ln -fs src/main/AndroidManifest.xml
android update project -t 24 -p "$(pwd)"
echo "${scname}: ...done"
echo "${scname}: removing android update project junk ..."
rm -v project.properties
rm -v build.xml
rm -v proguard-project.txt
rm -v AndroidManifest.xml
echo "${scname}: ...done"

This script is the first thing we run on any new machine where we code. It has to be run in the root project directory. Of course, android studio may have a GUI way of dealing with this, but I wouldn't know as I use a different editor. I also can't claim that the solution is general, but it "Works For Me" (tm).

回答25:

I have faced with the same issue on Ubuntu(both local.properties and ANDROID_HOME was added), but build fail persisted. So workaround is to add following lines

export ANDROID_HOME=/home/<user>/Android/Sdk export PATH=$PATH:/home/<user>/Android/Sdk/tools

directly to the studio.sh script (inside /usr/local/android-studio/bin)

Maybe it will be helpful.

回答26:

i encountered the same error but in my case i was cloning a project, the cloned project was built with Android API 22 which i did not install at the time(i had API 24 and 25 installed)........so i had to download the sdk tools for API 22

回答27:

For Windows:

1. Add ANDROID_HOME to the Environment Variables: ANDROID_HOME = C:/Users/YOUR_USERNAME/AppData/Local/Android/sdk
2. Add %ANDROID_HOME%\platform-tools to the PATH.
