So I installed the android sdk for Windows:
http://developer.android.com/sdk/index.html (the installation link)
And ran into the path variable problem. So I fixed that by changing "PATH" in enviroment variables to include where my java.exe file is located from the JDK.
But now when I open the android sdk manager, a cmd-like screen just briefly flashes on for half a second then disappears. I have no idea what's going on and how to get this thing working.
Make sure your java\bin directory is in your path statement before the windows\system32 directory.
The SDK Manager uses java and it was finding the one in the system32 folder.
In a CMD window, you can run 'where java'.
Don't forget to restart your CMD after changing the path variable for checking.
Alright, I had the same problem, and none of these answers worked for me (I'm running Windows 8). I tried running tools/android.bat and noticed I got some errors there. I investigated further and it seems there is something wrong in the code that finds your Java path.
This is how you fix it:
Open up tools/android.bat in your favorite text editor
Search for this piece of code:
set java_exe=
call lib\find_java.bat
if not defined java_exe goto :EOF
Replace it with this:
set java_exe=D:\Program Files\Java\jdk1.7.0_07\bin\java.exe
where the path is the path to your Java exe.
Run android.bat
(in my case I had to specify the path to java_exe in step 3 with no quotes to make it work.)
There are many reasons as to why the SDK Manager won't open. Rather than trying each one of them blindly, I recommend running the android.bat in a command window so you can read the error message and apply the correct fix.
In the latest version of the Android SDK, running "SDK Manager.exe" and/or "AVD Manager.exe" will not open anymore. Even the "Launch Standalone SDK Manager" link in Android Studio, which can be previously found in Android SDK Settings, is now gone.
It is now recommended to perform manual SDK and AVD management inside Android Studio. But for those who do not have an Android Studio or for those who do not like to open Android Studio just to perform SDK management, you can still manage the SDK using the command line tools, "tools/bin/sdkmanager.bat" and "tools/bin/avdmanager.bat".
This information is available when running "tools/android.bat". I think this is true for those who currently have Android SDK tooks v25.3.1 and above.
Same problem here.
Fixed!
I installed the correct Java stuff, all for 64 bit, because my system is x64, and nothing happened. So I went to C:\Users\[my name] and deleted the directory .android that has been created the first time the SDK ran, apparently with some wrong configuration.
Then it worked. You can try that. Delete that folder or just move it to the desktop and run the SDK.
Google removed the GUI for SDK starting from version 26. If you're using version 26, try downgrading to version 25. You can still open the SDK from Android Studio.
Source: Is GUI for Android SDK manager gone?
There appear to be several ways to launch the SDK Manager:
SDK Manager.exe in the root of the Android SDK.
SDK Manager.exe in sdk\tools\lib of the Android SDK.
Window -> Android SDK Manager menu in Eclipse
android.bat in sdk\tools of the Android SDK.
In my case, it looks like android.bat fails on the line:
for /f %%a in ('%java_exe% -jar lib\archquery.jar') do set swt_path=lib\%%a
As far as what that line is doing... if I manually run: "[path_to_java]java" -jar lib\archquery.jar
It successfully returns: x86_64
But when the batch file runs that same command, I don't know why but it fails with the error message:
Unable to access jarfile lib\archquery.jar
So the variable swt_path gets set to an empty string. Everything breaks down from there.
The batch file sets the correct value for the variable java_exe. Others have commonly reported this as a problem, but those workarounds weren't relevant in my case.
People have recommended commenting out the problem line by adding REM to the beginning of it, and adding a line to manually set the swt_path variable, which is a valid workaround:
REM for /f %%a in ('%java_exe% -jar lib\archquery.jar') do set swt_path=lib\%%a
set swt_path=lib\x86
BUT, the critical issue in my case is that it's choosing to load a jar file from either the lib\x86 or the lib\x86_64 folder here. At some point, things were getting confused between the BAT file error, a 32-bit JDK, and a 64-bit Android SDK.
SO, the workaround in my case was to:
Uninstall ALL versions of Java
Install the JDK
You can either use the 32-bit Android SDK and install the 32-bit JDK
Or use the 64-bit Android SDK and install the 64-bit JDK
But the "bitness" of the JDK should match the Android SDK. It appears that either of the 32-bit or the 64-bit will work on a 64-bit computer, AS LONG AS the JDK bitness matches the Android SDK bitness.
Edit "android.bat"
If using the 32-bit Android SDK/JDK, use lib\x86:
REM for /f %%a in ('%java_exe% -jar lib\archquery.jar') do set swt_path=lib\%%a
set swt_path=lib\x86
If using the 64-bit Android SDK/JDK, use lib\x86_64:
REM for /f %%a in ('%java_exe% -jar lib\archquery.jar') do set swt_path=lib\%%a
set swt_path=lib\x86_64
After doing this, I can successfully run the SDK Manager by running android.bat, or from the Eclipse menu (but still not by running either of the SDK Manager.exe files directly).
The simplest way is to run the program as administartor.
Right-click the SDK Manager -> Run as Administrator
That should solve the problem :)
I had the same problem, tried setting path variables and everything. What SDK manager needs is not the JDK, but the actual Java SE end user crap. Go to http://www.java.com/en/download/ie_manual.jsp?locale=en and download that. As soon as I finished installing that, it worked like a charm
Try adding the Java path (pointing to the JDK) to the System Environment Variables.
Right-click 'Computer' > Properties > Advanced system settings > Environment Variables
Then under System Variables, add a new variable.
Variable Value
JAVA_PATH C:\Program Files\Java\jdk1.7.0
Then edit the Path variable, prefix it with %JAVA_PATH%\bin;.
Locating the android.bat file in the tools folder worked for me. Funny that it is such a chore to get it to run. In my experience, usually .exe files run as expected. I'm not sure why it doesn't in this case... strange and annoying!
I had something totally different than the other answers.
I ran tools/android.bat and got
java.lang.NullPointerException

Basically it looked like I had a corrupt AVD configuration, so I went and cleared out my virtual devices and everything started working again! (Files in C:\Users\YourUser\.android\avd for windows users)
I faced the same issue and finally managed to solve it. I then created a step-by-step guide containing the universal fix to help all developers get past this issue asap: http://www.dominantwire.com/2015/03/android-sdk-not-opening.html
All the steps in short:
1.If you have jdk v1.8. Remove it and re-install jdk v1.7.x.x
2.Set paths to jdk and jre bin folders in the environment variables
3.delete (make a backup first) the .android folder present in C: > Users > [user-name] > .android
4.Set the JAVA_HOME variable keeping JAVA_HOME as the variable name and the path to bin folder of jdk as the variable value.
5.Go to [sdk-directory] > tools. Find and right-click on android.bat file and select 'edit' to open it in notepad and make the following modifications.
ORIGINAL
set java_exe=
call lib\find_java.bat
if not defined java_exe goto :EOF
MODIFIED
set java_exe=C:\Program Files\Java\jdk1.7.0_75\bin\java.exe
rem call lib\find_java.bat
rem if not defined java_exe goto :EOF
NOTE : Copy and paste your own java.exe path directory as explained previously.
ORIGINAL
for /f "delims=" %%a in ('"%java_exe%" -jar lib\archquery.jar') do set swt_path=lib\%%a
MODIFIED
rem for /f "delims=" %%a in ('"%java_exe%" -jar lib\archquery.jar') do set swt_path=lib\%%a
set swt_path=lib\x86_64
NOTE : If your android sdk is 64bit then mention set swt_path=lib\x86_64 otherwise if it is 32bit then keep it as set swt_path=lib\x86
Done! Fire up android sdk from android.bat file or from eclipse. It should open up just fine!
I tried almost all the solutions provided here. But nothing worked out. And finally, I downloaded tools(tools_r25.2.3-windows.zip) from the below link and replaced the tools sub-folder in the sdk folder. It started working.
https://developer.android.com/studio/index.html#downloads
Sharing this as an information though it's an old thread.
I recently faced this problem after I installed android emulator using the sdk manager of android studio - which also upgraded my android sdk tools to 26.0.1 (as it was a prerequisite - according to the sdk manager of android studio).
In my case, I simply replaced the tools folder of android sdk with tools folder from an older android sdk. This downgraded the android sdk tools, but now I can open the sdk manager using SDK Manager.exe.
Also make sure there is not as JRE before your JDK in PATH on Windows. Oracle always stuffs its own JRE into the path before anything else (I had installed Oracle Lite after I installed the android sdk).
Same problem here, I tried all solutions but nothing worked. Then I went into C:\Users\User_name and deleted the ".android" folder and then, the SDK Manager could open normally, and automatically created other ".android" folder.
I have solved this issue. If you are not able to open "SDK Manager.exe" from explorer or if you are facing any problem with SDK Manager.
Firstly check Java path is given in Environment Variable. (run Java command on CMD, or run Where Java on CMD as Administrator). If Java command is recognized, there might not be problem with Java
This might be due to broken SDK Tools. To fix it firstly rename tools folder (Android\Sdk\tools) to tools.old. Now download https://dl.google.com/android
/repository/tools_r25.2.3-windows.zip?hl=id.
After that Extract the downloaded zip files to Android\Sdk\ hence new tools folder would be extracted with all the contents for SDK. Now open SDK Manager.exe. If it opens your issue is solved. Please note that SDK Manager.exe is a launcher file that launches Android\Sdk\tools\bin\sdkmanager.bat. if you are satisfied with the answer please Upvote so that maximum users would solve the issue.

Been trying to get the SDK manager to run for a while now following various threads with similar problems I could find.
Another solution to consider is to move android SDK to a dir without spaces in its name.
For instance in my case it resided in:
e:\Program Files (x86)\Android\android-sdk\
and would fail.
When moved to:
c:\android_sdk_sucks\
It worked.
I tried all the most popular solutions before and no one worked for me, until I realised that the Android SDK folder must not have any spaces, so I changed it from "C:\Android SDK" to "C:\Android_SDK". As simple as that.
Nothing helps me from all this answers, but I found the right steps (Windows 7 64 bit):
1) Open android.bat from your sdk folder for editing;
2) Add exactly this two strings:
set java_exe=c:\Program Files\Java\jdk1.8.0_25\bin\java.exe
rem call lib\find_java.bat
instead of this:
set java_exe=
call lib\find_java.bat
if not defined java_exe goto :EOF
Where c:\Program Files\Java\jdk1.8.0_25 is your jdk folder.
3) Enjoy. SDK Manager will launch from Android studio IDE.
I installed Android Studio for Mac. I was not able to access the SDK manager through the IDE. It turns out I just had to have my JAVA_HOME environment variable set. Once I got this set I was able to launch the SDK manager.
I'd encountered the same problem. When running the android.bat I found the solution (if Java is installed in the 'normal' Windows directory, ie 'program files') you need to put quotes surrounding "c:/program files/" etc etc. Otherwise it cannot find java on "C:/program". (me dislikes spaces)
The issue with mine was that I could run SDK manager through double clicking android.bat but not when I double click on the actual SDK manager application. I solved this issue by setting a new environmental variable:
ANDROID_HOME = C:\Development\adt-bundle-windows-x86_64-20130911\sdk\
restarted my pc and now I can double click on the application and run SDK Manager. Hope that helps :)
I saw answers that provide workaround solutions by hard coding java.exe location and x86 / x86_64 architecture string in sdk\tools\android.bat. Those are quick solutions but did not solve the fundamental issue that I am actually curious of.
The actual problem that I encountered is, the batch script is not able to find another script/jar file and thus is failed to proceed. I could say the script was poorly written.
After I made the following changes in sdk\tools\android.bat, everything works like a charm.
Specifically, I added %~dp0\:
set java_exe=
call %~dp0\lib\find_java.bat
if not defined java_exe goto :EOF
...
for /f "delims=" %%a in ('"%java_exe%" -jar %~dp0\lib\archquery.jar') do set swt_path=lib\%%a
Now, try to launch the script and SDK Manager should come out.
p.s. My installation of OS, Java 8 and Android SDK are fresh and I did not do any of the extra configuration.
p.s. You may still need to configure PATH environment variable so that the script could find the suitable java.exe.
I test every way, But only working way was re Installing sdk-manager in same path as old one
http://quantumsupport.blogspot.com/2011/03/android-sdk-managerexe-wont-start.html
Create a new user account, either re-install or just start android.bat and it should work did for me
I encountered a similar problem where SDK manager would flash a command window and die.
This is what worked for me: My processor and OS both are 64-bit. I had installed 64-bit JDK version. The problem wouldn't go away with reinstalling JDK or modifying path. My theory was that SDK Manager may be needed 32-bit version of JDK. Don't know why that should matter but I ended up installing 32-bit version of JDK and magic. And SDK Manager successfully launched.
OS: Windows 7- 64 bit, Android SDK: 64 bit
Introduce a new 'System variable' named: JAVA_HOME with value: C:\Program Files\Java\jdk1.7.0_51
Right-click on SDK Manager.exe -> Run as administrator
A check list:
Make sure the java path in system variable 'Path' is something like: C:\Program Files\Java\jdk1.7.0_51\bin
There is no space in your folder name, replace something like C:\Android SDK with C:\Android_SDK
You can find your java with 'where java' command in command line
I am trying to setup Android Studio on my Mac. It is running OSX 10.9.1 Mavericks. I have installed the latest JDK (at the time of writing 1.7 update 45), and I installed Android Studio. I use Java 7 because I have some Java applications I have to run and they require 1.7. I have not installed Java 1.6, because it is ancient and old. Launching Android Studio from any launcher does literally nothing. Activity Manager never shows it running. I do not want to install Java 1.6.
I did some work and tried to run the executable via command line through the package contents, and for both executables, I get these messages:
I am unsure what I am supposed to do to fix this error. I'm not very adept on a Mac (still somewhat new to it, and its confusing to do power user stuff on this) so if anyone can help me figure it out that'd be great. I'm on the 2013 Macbook Air with plenty of resources for this to run.
Update: This also applies to Yosemite, El Capitan, and all the other versions of OSX that can run Android Studio.
Update 12/11/2014
As of Android Studio 1.0 RC3 you can follow this set of directions to make it work.
I figured it out. You have to edit the android studio's Info.plist file in the package so it uses 1.7. I don't get why Android Studio insists we install and use an outdated, vulnerable version of Java.
Full resolution: http://i.stack.imgur.com/yyYaG.png
To open the package you need to find the Android Studio.app file in the Applications folder and right click it > Show Package Contents.
Edit the plist (I think you might need to be root) and change JVMVersion from 1.6* to 1.7* (or 1.8*, or whatever JDK major version you have). I don't get why that made a difference since my original output said it was using 1.7 anyways.
This fix seems to apply to all of IntelliJ's IDEs (I've seen it on PyCharm as well), though other ones seem to support newer versions of java natively.
As answered by hasternet # Android Studio was unable to find a valid Jvm (Related to MAC OS)
For quick and dirty solution, Follow the answer by Mgamerz; open Android Studio in Finder (CTRL+Click > Show Package Contests > Contents > info.plist) and edit Key JVMOptions>JVMVersion from "1.6*" to "1.6+"
Recommended method as discovered by Antonio Jose is to edit environment variables in MacOS (messing with info.plist is not recommended)
either at program launch (opening the Studio through terminal rather than the icon)
$ export STUDIO_JDK=/Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk
$ open /Applications/Android\ Studio.app
or setting up the environment through AppleScript at every MacOS startup:
do shell script "launchctl setenv STUDIO_JDK /Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk"
do shell script "launchctl setenv STUDIO_PROPERTIES /Users/username/Library/Preferences/AndroidStudio/idea.properties"
do shell script "launchctl setenv STUDIO_VM_OPTIONS /Users/username/Library/Preferences/AndroidStudio/studio.vmoptions"
(Remember to save the script as Application. Antonio Jose managed with just the first line - AFAIK you can use .properties and .vmoptions to set up additional settings.)
Official instructions: http://tools.android.com/tech-docs/configuration/osx-jdk
(The reason why Android Studio want's to run off of JRE 1.6 is because it apparently makes the fonts look better - feel free to go through that "official" route and install JRE 1.6 # http://support.apple.com/kb/DL1572 - you can then set the JDK to 1.8 in the SDK Location settings - local.properties)
mgamerz is right - The release notes give a much better solution for rc3 and onwards - theres a idea.properties file
(or environment variable)
~/Library/Preferences/AndroidStudio/idea.properties
it also shows what environment variables you can use to set things like the jdk
export STUDIO_JDK=/Library/Java/JavaVirtualMachines/jdk1.7.0_67.jdk
ref : http://tools.android.com/recent/androidstudio1rc3_releasecandidate3released
I did below command on Mac Terminal to fix this problem, please make sure java version and path.
$java -version
java version "1.8.0_25"
Java(TM) SE Runtime Environment (build 1.8.0_25-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)
$ export STUDIO_JDK=/Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk
$ open /Applications/Android\ Studio.app
Hey Friends I just Figured it out a simple way to fix this for Mac users.
Open Terminal and type this -> java -version and hit enter.
Output will be something like this:
Now check your Java Version. My Java version is 1.8
So now we need to Open Contents of our Android App.
For that right click the Android.app and then select Show Contents
Like this
Now there will be Content folder, Open that Folder and there you will find Info.plist
Open this info.plist
And you will see this.
In this expand the JVM
Here you will see the JVM version showing 1.6* but our jvm version is 1.8 (for example my jvm version is 1.8)
So we need to change this number according to our jvm version, so i changed it to version 1.8*
Then click save. And you are done.
Now you will see setup wizard running
And you are ready to start your first android programming app.

I found that downloading an extra Java bundle from Apple fixed the issue.
If you search for this problem then I found the second link was to a blog having exactly this problem, all credit goes to him here
I know that posting links isn't an answer but as you can see from the resolution you need to make sure you have an up to date version of Java and also the Java bundle from Apple, for this reason I have also included the searches needed to get to these websites.
Here is where to download the latest version of Java
If this link is broken then searching "java latest version" return it at the top of the Google list
Here is where to download the Apple Bundle
If this link is broken then searching "Java for OS X 2014-001" returns it at the top of the Google list
For me trying to solve this problem it appears that initially it was an issue that required a work around and then Apple released an official work around download meaning that fiddling in plists is not necessary any more.
