How to make Android Studio STOP generating local.properties?

I have set an environment variable ANDROID_HOME, which points to my android SDK location. However, every time I open my project in Android Studio it places local.properties file to the root of my project and copies my SDK location from ANDROID_HOME to this file. I want Android Studio use ANDROID_HOME directly, without generating local.properties.
Why? I'm on Windows 10 and I use Bash for Windows. I want to run command line using Bash while running Android Studio from Windows. For this I need two ANDROID_HOME environment variables, one for Windows, one for Bash. This is because although they point to the same (windows) android SDK the format is different, for Windows it is C:\Users\me\Android SDK while for Bash it's /mnt/c/Users/me/Android SDK. When Android Studio creates local.properties with windows path Bash becomes broken since apparently local.properties takes advantage over ANDROID_HOME, so I have to delete it manually.

You might find this article useful:
Posix path conversion (mingw.org)
The gradle android plugin "Application" extension
(your regular gradle-android interface) has a property
sdkDirectory. Perhaps this can override it? I can't check.
I think there is a configuration switch for bash on Windows to parse path separators Windows-like, can't seem to find it, it is buried deep inside MinGW or MSYS docs I think.
Last resort - git Hooks. Read the ProGit book chapter on Hooks.

The Android will generate this file always when gradle sync it. But if you delete it and define ANDROID_HOME and ANDROID_NDK_HOME environment variables, every time that generates it will read ANDROID_HOME and ANDROID_NDK_HOME.
If you want to build your project in many computers with different home folders, just keep the local.properties outside the source version control.

Cannot detect SDK path in WebStorm 2016.3

I am trying to create a PhoneGap application using WebStorm 2016.3 IDE.
I am following this link link. I am able to create a project from the steps but while running the app I'm getting errors. While setting emulator I've found that Android SDK was not found.
I am unable to find how can I set that path here and the error I got is:
...and in log cat
"C:\Program Files (x86)\JetBrains\WebStorm 2016.3\bin\runnerw.exe" "C:\Users\Sa E\AppData\Roaming\npm\ionic.cmd" run --emulator android
✗ You cannot run iOS unless you are on Mac OSX.
I've tried some things by google but the data is for old IDE and I can't see such options with my current IDE.

I ran into the same issues on Windows. I added a system variable ANDROID_HOME with the address of the sdk folder. In my case it was
c:\Users\Andrew\AppData\Local\Android\sdk
After that, I restarted WebStorm, and it works fine.
PS make sure that you set up the project properly. Try creating a new project with type "PhoneGap/Cordova", then in the terminal type the following commands:
ionic start MyProjectName
ionic serve
If everything works at this point, then proceed:
ionic platform add android
ionic build android
ionic emulate android
You can use run instead of emulate if you have GenyMotion installed and running

I used #Andrew's answer, but did not manage to make it work. It appears i needed more Environment variables; so, after many searches, I found this link on Cordova documentation which helped me in making PHPstorm recognize the Android SDK. The question was about Webstorm, but the Cordova plugin requires the same environment variables.
Here's a quote from that site (if you do not know how to set environment variables, follow the above link to get help):
Cordova's CLI tools require some environment variables to be set in order to function correctly. The CLI will attempt to set these variables for you, but in certain cases you may need to set them manually. The following variables should be updated:
Set the JAVA_HOME environment variable to the location of your JDK installation
Set the ANDROID_HOME environment variable to the location of your Android SDK installation
It is also recommended that you add the Android SDK's tools, tools/bin, and platform-tools directories to your PATH

I faced the same problem with intellij idea ultimate on linux, while trying to run a cordova/phone gap project. Weirdly enough, the commands where running normally from the command prompt and the embedded terminal, however, trying to create a run configuration, I got the infamous errors.
I have the environment variables set correctly, but, I have them set in ~/.bashrc which intellijidea seems not t read.
I tried to add the variables manually in the same screenshot you included, with no success. The solution was to add ANDROID_HOME to the /etc/environment, rebooted, and everything worked as expected.

To add android in phonegap platform using cordova [duplicate]

Helo,
I am currently trying to build the base phonegapp android app that's automatically created, so I navigated to the directory... but when I use the command
phonegap build android
I just get this random error, as shown in the attatched picture.
Extra info
I am currently on Windows 8, and am completely new to making apps, and am new to the command line as well. Not very familiar with this stuff...
What I'm trying to do would be called 'compiling', right?

Yeah, I had the same problem yesterday - but with a little help of a colleague I got it!
Step by step tutorial (for Windows)
Install node js
Install phonegap using command line: npm install -g phonegap
Install Android SDK
Launch Android SDK Manager and install Android 4.4.2 (API19)
Because latest phonegap/cordova version requires this
Documentation for Android SDK and SDK Platform should be enough
Also update already existing packages
Create an environment variable called ANDROID_HOME which points to destination of Android SDK. e.g. C:\Users\You\AppData\Local\Android\android-sdk
Download Apache Ant and extract the archive somewhere
Create an environment variable called ANT_HOME which points to destination where you have extracted Ant
Install JDK (Java Development Kit) for your System. Before you are able to download, you have to accept the licence
Create an environment variable called JAVA_HOME which points to destination of JDK
If you want to add plugins via phonegap automatically you should also install GIT.
Last but not least you need to add the following directories to PATH environment variable:
%ANT_HOME%\bin;%ANDROID_HOME%\tools;%ANDROID_HOME%\platform-tools;%JAVA_HOME%\bin
Each folder is separated by a semicolon
Setting environment variables will take effect just for new command line windows. So you should reopen it, after the whole process.
Easy, isn't it? ;-)
Now you can use phonegap build android after you've created a new phonegap project. If you have your smartphone plugged via USB and installed the USB drivers, and activated the USB Debugging on smartphone, you may use
phonegap run android
And the ready build APK will be transfered and executed on your smartphone. Perfect for testing.
If you want to create a final release APK, go to
YOURPROJECT\platforms\android\ant-build
and enter ant release.
You'll find the final APKs in YOURPROJECT\platforms\android\bin.
They are unsigned, here is a Noob guide to signing an APK.
I have tested a Barcode Scanner example, and it works seamlessly.
Have fun!

also check android in cmd, if it says: 'xcopy' was not recognized.
then add to your path:
%SystemRoot%\system32; %SystemRoot%; %SystemRoot%\System32\Wbem;

Armin's guide is perfect. But if you still fail you can do this.
Phonegap platform files stay in C:\Users[username].cordova\lib folder. Go there and remove android/ios/bb... driectory.
For best result run this command:
npm cache clear
After that try again, clean platfrom files will be download and build your project.

What exactly is "tools.jar" in the Android SDK?

So, I've been trying to build a project in LibGDX for about 10 hours now. In case you'r unfamiliar, LibGDX is one of those platforms where you specify a project directory at the start, along with any required SDKs and then when you're ready to start coding it will generate a project for you.
Anyway, I've been having a problem where every time I try to build it fails with the single error message:
Execution failed for task :core:compileJava.
Could not find tools.jar
I'm guessing "tools.jar" is a package within the Android SDK, as this is the only repository needed to build, it doesn't ask for a JRE or even the Java SDK. just the Android SDK.
I have been looking in the SDK manager, I have installed all of the packages labelled "Android-SDK Tools", "Android-SDK Platform Tools" and "Android SDK Build Tools" but there is nothing else that includes "tools.jar", I am looking for some light shed on this topic as it is a very grey area. I would like to know where this .jar file comes from and what exactly it includes. Can it be installed from the Android SDK?
There have been similar questions like this before which only fit narrow situations, If someone could provide a holistic description of the tools.jar package it would benefit a great deal for me and everyone else that needs it in their 3rd-party android IDEs.
For the record, it's building with Gradle and my current SDK is well-equipped enough to build full-fledged apps in Android Studio.
Please don't answer this question with a question unless I have left out some information that is dire to finding an adequate solution

Try copying tools.jar from %JAVA_HOME\lib to Android Studio\lib

For me, copying tools.jar to Android lib folder alone didn't solve my problem.
But I also had to create a System Variable 'JAVA_HOME' in Windows Environment Variables with path to the latest JDK folder.
Restarted Android Studio, and this solved by problem.

My Android Studio Version: 4.2.1
The "tools.jar" is provided by Oracle JDK which is required by android studio for compilation - I have faced this issue after updating android studio to latest version in my PC.
To Resolve the issue follow below steps:
In Android studio File -> Project Structure -> SDKs (Under Platform Settings)
A) Add JDK path by pressing '+' symbol in middle pane if suppose JDK/JDK home path is not present in the middle pane already (Middle pane also contains the Downloaded Android SDK's)
B) Java sdk will be usually present/installed in the path
64 bit => "C:\Program Files\Java\jdk1.X.Y_ABC" (In my PC it is 1.8.0_202) or
32 bit => "C:\Program Files (x86)\Java\jdk1.X.Y_ABC"
If suppose you don't have JDK installed in your PC, please download and install from Oracle Java website
https://www.oracle.com/java/technologies/javase/javase-jdk8-downloads.html
Set JDK and JRE Path(Download both from webpage mentioned in step 2) in system environment variable
A) Press windows key type "Edit the system environment variables" and open the application
B) Go to Advanced -> Environment Variables
Under system variables add JAVA_HOME and JRE_HOME as below
Set Windows system environment variable
Add jdk lib path on the Path environment variable under user variables (this step is required only if the error not resolves with the previous steps)
C:\Program Files\Java\jdk1.X.Y_ABC\lib

In my case, I have five jdk and some have tools.jar and other not, my solution is copy paste this tools.jar in all lib of jdk.

Nothing worked for me. So I Copied tools.jar and pasted it in C:\Users\UMAR_\AppData\Local\Android\Sdk\platforms\android-30 which is the path to the library for the Android API 30 Platform. I pasted tools.jar in every folder and it start working.
I didn't have tools.jar initially but followed this link and downloaded https://www.oracle.com/java/technologies/javase/javase-jdk8-downloads.html
Also added to a environment variable.. but what worked was in the first para, I still don't know if adding to variable was necessary or not.

Installing new Android studio Beta v.0.8.14

Hello I am new in Android development
So as suggested by google I downloaded the latest October 2014 beta version of Android Studio to start developing because they will end up solely with the Android Studio IDE so I thing it is a good idea to get used of it...
To install they just give you a zip file. I unzipped it and followed the text instructions which were simple BUT I cannot find the files and folders the say should exist in their unzipped folder/files :s .
The instructions are
'' To set up Android Studio on Windows:
Unzip the file, android-studio-ide--windows.zip and launch the studio.exe file.
Follow the setup wizard to install Android Studio and the SDK Tools.
On some Windows systems, the launcher script does not find where Java is installed. If you encounter this problem, you need to set an environment variable indicating the correct location.
Select Start menu > Computer > System Properties > Advanced System Properties. Then open Advanced tab > Environment Variables and add a new system variable JAVA_HOME that points to your JDK folder, for example C:\Program Files\Java\jdk1.7.0_21. ''
Although I find the studio.exe at the path \android-studio-ide-135.1538390-windows\android-studio\bin
I cannot find any kind of a setup wizard for the SDK Tools!!
When I start the studio.exe program and I go to Configure/Project Defaults/Project Structure
the java sdk has been found but the android sdk folder naturally it is not.
And also the Configure/SDK Manager is not enabled.
What obvious thing am I missing here??
Thanks

If you downloaded android-studio-ide-135.1538390-windows, then it only contains the IDE and not the Android SDK. You need to download it separately:
http://dl.google.com/android/installer_r23.0.2-windows.exe
link
You will then point Android Studio to your SDK installation location.
