Android SDK installation doesn't find JDK
I have installed Java runtime 6 to C:\src\libraries\jre6.
I installed Java JDK to C:\src\libraries\javasdk.
My %PATH% is set to:
PATH=C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\system32
\WindowsPowerShell\v1.0;C:\src\libraries\javasdk\bin;C:\src\libraries\javasdk;C:
\src\libraries\javasdk\jdk\bin;C:\src\libraries\javasdk\jdk;C:\src\libraries\jav
asdk;
When I run the Android SDK installer I get the error:
"Java SE development Kit (JDK) not found"
I'm at a loss as to what the Android SDK cannot really find.

Windows 7 32 bit has the same behaviour as Windows XP SP3. Hit BACK and then NEXT again and you're able to install the Android SDK.

The answer is bang on, but some clarification that might help some not familiar with registry editing (like me).
Run regedit.
Find [HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Development Kit]
Right click on the key and click export, then save the file to the desktop.
Right click then click edit.
Add Wow6432Node to the path of each key in the file. See above (#Rog_enk) for an example. Save.
Back in regedit, click File->Import and select the file from above. Done.
Try the SDK installer again.

On Windows 7 x64 the Android SDK Installer is looking for the JDK in the HKLM\SOFTWARE\Wow6432Node\JavaSoft registry branch.
But in reality the JavaSoft entry was placed in HKLM\SOFTWARE\JavaSoft. I copied all JavaSoft branch to the path search, and then the installer found the JDK.

Just press back, then next and it will find it. Android SDK installation doesn't find JDK

Windows 7 64 bit - same behaviour as windows XP SP3 and Windows 7 32 bit: Just set JAVA_HOME = C:\Program Files\Java\jdk1.6.0_14 or whatever your actual path, start SDK, and after you'll get error - hit BACK and than NEXT again and you're able to install the Andriod SDK

It seems that creating and setting my environment variable, CLASSPATH, to C:\src\libraries\jre6\lib fixed my problem. I downloaded the Android SDK zip file, put it where I wanted it. I was able to proceed from there.

Problem occuring when trying to install Android Studio

When I'm trying to install android studio on my 32 bit Windows 10 computer, it says that an error occurred while trying to compute required packages. What should I do?
Solution:
Download the Java SE Developement Kit (Directdownload for 32Bit) and install it.
After that you can access Android Studio on it's site choosing the No .exe installer version:
Extract it and go into the bin folder and execute studio.exe (this is for 32bit).
PS: The studio64.exe is ONLY recommend for 64bit machines.
This will work! I bet you have installed the wrong Android Studio Version. So uninstall your current Android studio and follow the steps above. Cheers.

Android Studio does not launch after installation [duplicate]

Android Studio installation on Windows 7 fails, no JDK found
(29 answers)
Closed 9 years ago.
I've just downloaded the new Android Studio IDE released today, and installed it. When I double-click the icon to launch it, nothing happens. I've tried every shortcut to it, as well as the .exe in the installation folder.
I've also tried restarting the machine, uninstalling / restarting, and installing to a folder location without spaces. Does someone know why Android Studio won't start?
I set my JDK_HOME environment variable to point to my Java (1.7) JDK path, and it worked.
My JDK path was:
c:\Program Files\Java\jdk1.7.0_21
but it will vary depending on the version of your JDK.

Android SDK deosn't think JDK is installed? - Windows 7

On Windows 7 I have installed the Java SE JDK, then rebooted.
When I then run the Android SDK installer, there is a warning that the JDK is not installed.
I found that if I press the Back button on the Android SDK installer, then press the Next button again, it works!
Did you install 32-bit version or 64-bit version?
Check out here for Windows 7 / Android Tools setup :
https://stackoverflow.com/questions/4588548/help-jdk-not-detected-problem-during-android-sdk-tools-setup
Also, check out your PATH environment variables to confirm JDK is setup and referenced!
And as commented below, also check out JAVA_HOME variable.
i had the same problem, tried all the solutions but nothing worked. The problem is with Windows 7 installed is 64 bit and all the softwares that you are installing should be 32 bit.
Android SDK itself is 32 bit and it identifies only 32 bit JDK. So install following softwares.
JDK (32 bit)
Android SDK (while installing SDK, make sure install it in directory other than "C:\Program Files (x86)", more probably in other drive or in the directory where Eclipse is extracted)
Eclipse (32 bit) and finally ADT.
i tried it and all works fine.
You Should Create an Environment Variable to Point to Your java Directory.
Go to My Computer > right click on a free space > choose properties > in the left column choose "Advance System Setting" > Go to Advance tab > push Environment variable button > in System Variable click on New :
Variable name : JAVA_HOME
Variable value: C:\Program Files\Java\jdk1.7.0_06
You should be careful about path if you add path like this "C:\Program Files\Java\jdk1.7.0_06\bin" or this one "C:\Program Files\Java" it will not work.
When you downloaded sdk, running via browser's downloaded files section right? application can't detect java in this state. if you run it via directly its own folder, it will find sdk. simple
My is configuration Windows 7 64-bit.
I didn't want to uninstall 64-bit jdk and the other suggestions weren't working. So I just downloaded the 32-bit and re-ran the windows installer.
Voila, it works and doesn't take the 32-bit either. It takes the 64-bit higher version instead.
I feel it just feels safe with the presence of the 32-bit jdk :P

Has anyone been successful in using 64-bit Eclipse for Android 2.3 dev on 64-bit Windows 7?

Has anyone been successful in using 64-bit Eclipse for Android 2.3 dev on 64-bit Windows 7?
Please answer positively only if, when you invoke the emulator via Eclipse's Run (Ctrl+F11), your app-to-be-debugged's APK is installed automatically onto the Android emulator and you are running this same exact configuration:
Windows 7 Ultimate 64-bit.
JDK 64-bit (jdk-6u23-windows-x64.exe installed.)
JDK 32-bit (jdk-6u23-windows-i586.exe installed.)
Eclipse Classic 3.6 64-bit (eclipse-SDK-3.6.1-win32-x86_64.zip)
Android 2.3 SDK Starter Package
If you are able to fully use 64-bit Eclipse for Android 2.3 dev on 64-bit Windows 7, please describe the steps you performed to make this happen.
As of now, the following steps did NOT work for me:
install the 64-bit JDK
install the 32-bit JDK
unzip android-sdk_r08-windows.zip to
C:\android-sdk-windows
append C:\android-sdk-windows\tools
to %PATH% in System env vars.
Run C:\android-sdk-windows\tools>android.bat
Install ADT Plugin via Eclipse
Create "Android 2.3 - API Level 9" virtual device via Eclipse
Window > Preferences > Java > Installed JREs: [Search...]
I received 3 great answers here although none of those described configurations really match the original configuration described in the question, but...
The last 2 answers (especially the one from #Nicholi) prompted to spend the time on yet-another-round of pulling my hair in an attempt to find a solution to an unexplainable problem.
And I found it! My own configuration now works on 64-bit Windows 7 and so the short answer is: Yes.
Here are the detailed steps, in order, that worked for me (cut & keep):
Step 0:
***********************************************
****** UNINSTALL THE COMODO FIREWALL !!! ******
***********************************************
Comodo Firewall, AKA CIS, turned out to be the sole problem leading to the time wasted between December 2010 (when I posted this request for help) and February 2011 (When I finally nailed the problem down). Note: Disabling the firewall doesn't help, only complete uninstall really works.
Step 1 (JDK 6 64-bit):
Create %JAVA_HOME%: C:\Program Files\Java\jdk1.6.0_23
Append to %PATH%: C:\Program Files\Java\jdk1.6.0_23\bin
Run: jdk-6u23-windows-x64.exe
Note: It is not necessary to install the JDK into C:\Java. Sticking with the Windows Folders conventions is preferred because it helps you remember which package is 64-bit and which is (still) 32-bit.
Step 2 (Eclipse Classic 64-bit):
Unzip eclipse-SDK-3.6.1-win32-x86_64.zip into C:\eclipse
Note: It is critical to have the eclipse directory directly under C:\ and not under "C:\Program Files" (otherwise, ADT Plugin install will incur missing packages problems).
Step 3 (SDK Starter Package AKA "Android SDK"):
Create %ANDROID_HOME%: C:\android-sdk-windows
Append to %PATH%: C:\android-sdk-windows\platform-tools
Run installer_r09-windows.exe and install to C:\android-sdk-windows
> Check 'Start SDK Manager'
> All are selected. Accept. Install. Yes, restart ADB.
Step 4 (ADT Plugin for Eclipse):
Help > Install New Software > Add...
Name: ADT Plugin
Location: https://dl-ssl.google.com/android/eclipse/
Check "Contact all update sites during install to find required software'!!!
Work with: All available sites
+ Developer Tools
+ Android DDMS 9.0.1.v201101191456-93220
+ Android Development Tools 9.0.1.v201101191456-93220
+ Android Hierarchy Viewer 9.0.1.v201101191456-93220
> Next
> Next
> Finish
> Restart Eclipse
Step 5 (Android Virtual Device):
Open Eclipse. Then:
Window > Android SDK and AVD Manager
> Virtual Devices [New...]
Name: AVD23
Target: Android 2.3.1 - API Level 9
SD Card: 1024 MiB
[Create AVD]
I myself have never used the Eclipse "classic" version, I always get the Java version as another poster mentioned (the 64bit version). Personally no idea what the difference is. I am guessing this is where your problem may stem from?
It works perfectly on Windows 7 x64 (Home Premium here), 64-bit and 32-bit JDKs installed, latest Android SDK and ADT plugin. I'm not sure which JRE is actually used, never bothered to find out (wouldn't be surprised if its 32bit). Also the JDK versions I used (quite awhile back) were 6u21, since then my 32bit version has updated to 6u23 but 64bit has not. Couldn't tell you the exact order as I don't recall (it was quite awhile back). Likely I installed the JDKs first, then extracted Eclipse, install/downloaded Android SDK, then installed ADT plugin.
Has always started up emulator fine, installs APKs, and debugs as expected. I also do alot of dev'ing on my Nexus One.
One recommendation I have seen alot is NEVER install any of the tools to the typical "C:\Program Files" because of spaces in filepaths. Why this is still a problem in 2011 I will not know, but putting Eclipse, JDK, and the Android SDK all straight off the root of some drive is likely to lead to significantly less issues apparently.
Edit: I uninstalled my current versions of Java, and removed eclipse/android sdk to startover
Installed jdk-6u23-windows-x64.exe to C:\Java
Added JAVA_HOME env variable pointing to C:\Java\jdk1.6.0_23
Added Java bin dir to PATH env var ;C:\Java\jdk1.6.0_23\bin
Extracted eclipse-java-helios-SR1-win32-x86_64.zip to C:\eclipse
Installed installer_r09-windows.exe to C:\android-sdk-windows
Downloaded necessary SDK versions
Installed ADT plugin through Eclipse interface, point to android SDK dir
Added ANDROID_HOME env variable pointing to C:\android-sdk-windows
Added Android platform-tools dir to PATH env var ;C:\android-sdk-windows\platform-tools
After this everything seems to work fine (except for DDMS in Eclipse, still fidgeting with that). And that is without the 32bit version of Java installed (neither JRE or JDK). Only 64bit is installed.
Is the solution to use eclipse-java-helios-SR1-win32 instead of eclipse-java-helios-SR1-win32-x86_64 when using a Windows 7 64 bit OS on a 64bit machine?
Hope this helps, if anyone else is having this issue.
Following configuration works perfectly fine for me.
Windows 7 Professional 64 bit
Eclipse Helios 3.6.1 64 bit (JavaEE)
JDK 6u23 64 bit
Android SDK 2.3
ADT 8.01
My sequence of steps:
Install 64 bit JDK. Update PATH and JAVA_HOME env variables.
Uncompress Android SDK and get all the required versions 7, 8 and 9. Add ANDROID_HOME env variable.
Uncompress Eclipse 64 bit and install the ADT plugin and then configure the Android SDK in Preferences page of Eclipse.
Thanks for the collective wisdom which has enabled me to restore the ADT functionality within an hour of reading this page. I had to fix one more item, eclipse refused to compile my android application and complained about all sorts of nonsensical problems e.g. unable to find {relative-path}\R.java even though I could view it in eclipse and from the command line; and build path problems.
I discovered it was using a 32-bit JRE (Window->Preferences->Java->Installed JREs) of
C:\Program Files (x86)\Java\jre6
I added an entry for the 64-bit JRE
C:\Program Files\Java\jre6
and selected it as the default JRE.
My android project then built cleanly again :)
I'm still troubleshooting it, as my configuration is totally messed up - many versions of java and mix of 32/64 bit, so I'm starting from scratch.
I noticed one thing, which might be solution to this problem. I found 3 java exe files in my windows\system32 folder. That's why, when u run 'java -version' from the command line, you get java 7! Even when you amend system %PATH% to have java 6 there, it won't work until you remove executables from system32.

Android Plugin for Eclipse problem

I am using a laptop with Windows 7 Home Prem x64. I have installed Java JDK1.6.0_18 and Eclipse Gallileo. I have downloaded and installed the latest version of Android SDK with several Platforms loaded and a AVD defined. I can install the Android Eclipse plugin from the remote site stated in the instructions. The plugin installation performs without any errors and I can verify that the plugins are indeed installed. My problem begins when I go to Windows -> Preferences, there is no Android section to configure. And when I go to File -> New -> Project, there is no Android Project to choose.
I have uninstalled the plugin and reinstalled at least 10 times, trying different things and still no luck. I originally had the 64 bit version of the JDK installed, but removed it and installed the 32 bit version.
Has anyone heard of this type of problem? Is it because I am using Windows 7?
Thanks for any help.

Have you tried doing the following and have it manually install from there:
Help -> Software Updates -> Add site -> http://dl-ssl.google.com/android/eclipse
I didn't see it on the website regarding if the ADT or the SDK is not compatible with Windows 7.
When you said you installed the 32-bit version, did you get it working or not at all?
maybe you have space in your Eclipse or Android SDK path? do not use spaces in path. I had similar problems and that's because spaces.
I encountered the same problem on my Mac, and found out what my problem was. When I was futzing around with stuff I had renamed the config.ini file in the eclipse/configuration folder. When I renamed it back to config.ini and restarted eclipse everything Android was back in the menus for me.
