Sorry if this is the wrong Stack Exchange, but this is where most of the questions were asked when I googled my problem.
For some time now I've been having problems with Android Studio and the AVD/SDK. It seems to be a relatively common problem, but I haven't been able to fix my problem with any of the solutions that worked for everyone else. This is the error I'm getting whenever I try and run the AVD or the SDK:
Cannot launch AVD manager.
Output:
Access is denied.
ERROR: No suitable Java found. In order to properly use the Android Developer
Tools, you need a suitable version of Java JDK installed on your system.
We recommend that you install the JDK version of JavaSE, available here:
http://www.oracle.com/technetwork/java/javase/downloads
If you already have Java installed, you can define the JAVA_HOME environment
variable in Control Panel / System / Avanced System Settings to point to the
JDK folder.
You can find the complete Android SDK requirements here:

I've tried re-installing everything Java (Both JRE and JDK), reinstalling Android Studio, running as admin, configuring permissions and a bunch of other stuff. I'm running Windows 7 and I've tried both JDK/JRE 6, 7 and 8 (JDK 6 worked very poorly though). I don't really know what kind of information you need to help me solve this problem, but I'll supply any information needed as fast as I can. Thank you very much.
Edit:
Please note that Java IS installed. Both Java and Javac is working fine in cmd.
I can suggest that Go to Windows -> Preference -> Java -> Compiler
And try with different java version.
Probably your Java folders are in the path (and that's why they work from CMD) but your JAVA_HOME is not defined.
As you are on Windows try creating a System Variable following those steps
Try (re)installing the ADT and see if it works. If not, go to the sdk's root folder ([PATH TO THE UNZIPPED ADT]/sdk) and open the AVD Manager.exe. Does it still give you the same error? If not, try to open the SDK Manager.exe and make sure you've installed all the propper APIs. I'd recommend installing at least the SDK Tools and Platfom-tools, and all of API19 (Android 4.4.2).
Finally Solved my problem! Some software I had previously installed had created a Path in User Variables, which was the one I was using for my JDK path. I tried using the Path in System Variables and it worked just fine! Thanks to everyone who took time to help me.

I am trying to get Android Studio installed on Cent OS 6.5. I have downloaded and unzipped the package to /usr/share/applications/Android-studio/.
I have installed jdk 8 in /usr/share/applications/ (as I understand you just unpack it there, no need to compile or execute anything...?)
I have appended /etc/profile with "JAVA_HOME=/usr/share/applications/jdk1.8.0_1118"
When I execute the studio.sh file the app begins to run (I see some Java messages in the shell) then I get the error:
"JDK Required: 'tools.jar' seems to be not in Studio classpath.
Please ensure JAVA_HOME points to JDK rather than JRE".
I think this means something is wrong with my JDK files but I don't know what. I have followed multiple tutorials online about how to fix this error including the guides on Android studio and Oracle's websites and as far as I can tell I've done everything correctly, but I am still getting this error. What am I missing?
Thank you for your help.
After looking through some answers to similar questions (that didn't receive any votes so I had overlooked them previously) I solved the issue. I had to copy the 'tools.jar' file from /usr/share/applications/jdk1.8.0_1118/lib to /usr/share/applications/android-studio/lib. That did it. It is up and running. Apparently this file is missing from the package downloaded from the android studio website. I hope they fix that soon and save future users hassle.
I was trying to install the android studio in my computer (Win 10 - 64x).
By the name, probably the version is 1.4.1:
android-studio-bundle-141.2456560-windows.exe
But I keep receiving a error saying: "We could not detect a Java Development Kit (jdk) v7 or newer on your system."
Currently, I have the jdk1.8.0_71 (64x) version installed. The environment variables JAVA_HOME and JDK_HOME (not sure if this specific one is really necessary) set, and the Path has been edited as well.
As you can see here, every variable and settings are set
Also, I've tried changing the jdk version to the 1.7.0_79 (64x), and I've also tried placing the path between quotes.. But all of it was in vain
It is strange, because I'm a java developer (not android), and I've never seen something like that.
p.s.: Every time I change the system environment variables I restart the computer to ensure the functionality of those variables.
Make sure both your Android Studio & JDK 7 are of either of 64bit or 32bit both. If JDK is of 32bit and Android Studio of 64bit or vice verse, It won't work together.
Assumed that, you have set your JAVA_HOME & PATH correctly.
Thank you SO MUCH Grimmy Vorner!!
I spent my day reading everything and I finally was able to get it working by using the "SDK tools package" (android-sdk_r24.4.1-windows.zip) instead of the "Android Studio package" (android-studio-bundle-143.2915827-windows.exe) from https://developer.android.com/studio/index.html
Also, go to Build -> Edit Build Types -> SDK Location -> JDK Location and make sure it is pointing to the correct jdk version (JDK 7 or JDK 8).
I tried everything that all of you said, but nothing seemed to work. After all I discovered that I can download a zipped version instead of an installation wizard. All I had to do was unzip the android studio and execute the studio64.exe file, and then everything worked perfect.
Still don't understand why it was not working properly with the installation wizard..
Anyway, thank you all for you effort!
I hope that all this information can help others in the future!
I want to learn to make Java Android applications in Android Studio,
I downloaded both the Java JDK and Android studio on an external drive (D:).
I'm getting this error on start-up:
tools.jar seems to be not in Studio classpath.
Please ensure JAVA_HOME points to JDK rather than JRE.
So I already searched Stackoverflow for the same error, but my Java folder seems to be a little bit different (it makes me wonder if I downloaded the correct JDK).
Because the advice was to either move tools.jar or change the value of JAVA_HOME.
None of those are an option because i can't seem to find the JDK in the Java folder. (D:\Java)
Did I install the wrong JDK?
Thanks in advance.
1) Download JDK: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
2) Android Studio -> File -> Project structure -> JDK location. Point at where you have installed it.
I wanted to develop an android app a few months ago, so I followed all the steps from here-> https://developer.android.com/training/basics/firstapp/index.html?hl=p and I believe I downloaded all the tools I needed. I never got around to developing anything, so I tried starting again a few days ago. When I went to the above mentioned website, it said download the new versions of this and that, so I did. I tried following the steps, but now when I try to open eclipse, I get an error saying:
"Error could not find Java SE Runtime Environment".
My questions are:
How do I delete everything and start from scratch? I wan't to delete eclipse, sdk manager, sdk folder, everything. I want to follow the download instructions all over again and see what happens because it did seem to work the first time i tried a few months back.
Do I just delete some programs from control panel?
If this is not easy, how can I fix the error I'm getting when trying to open eclipse?
Edit: windows 7, 64-bit OS, if that helps
That sounds more like a problem of a corrupted Java installation. Check the JAVA_HOME environment variable. If this is empty fix this and try again.
To delete eclipse and the sdk just delete them from where you installed them.
SUGGESTIONS:
0) I assume you're running Windows. Please specify if you're on a different platform.
1) Delete Eclipse.
If you're not using Eclipse for anything else yet, I would strongly encourage you to delete it.
2) Uninstall your Java JDK (from Control Panel).
Download and install the JDK from Oracle: http://java.oracle.com.
3) Download and install the "ADT Bundle for Windows": https://developer.android.com/sdk/
In earlier versions of Android, you had to install Eclipse, the Android Plugins, and the Android SDK separately. I believe this is the procedure your link describes.
The newer "ADT Bundle" saves you this trouble. If Android is the only thing you're using Eclipse for (at least for now), you definitely want the ADT bundle. And you can probably ignore most of the instructions in your link.
'Hope that helps..
I'm using Windows-7 64 bit and I have installed this(jdk-7u45-windows-x64) updated JDK in my system. My SDK was updated upto API level 18(Android 4.3).
When i click on SDK manager in the eclipse, it does not start. I tried open it directly with Administrator permission also. But it does not start. I had tried to set the variable path like these.
But I'm always getting the same error like this.
After I found that in my find_java.exe get the java path from windows\system32 as shown below .
How can I set the Java path to my installed java folder.
Need some one help to figure it out. For Reference look at this link also.
SDK manager not starting
While setting the environment variable try JAVA_HOME variable pointing the bin directory.
because the android checks the java.exe in particular path.
I am new to android,As long as i studied ,Android requires Java 1.5 or 1.6. You are using 1.7
Google does not add complete jdk 1.7 support to android system requirement(some api are exception) .. It does not mean that you should not have jdk 1.7. you should also have 1.6 jdk for compiler compilance. it is a better way to avoid using 1.7 jdk ,if u dont want jdk 1.7 features.
http://developer.android.com/sdk/index.html see the system requirements and even if u developed using 1.7...when you installing your app in real device .we may face signing issue.
you may use some jar file which targetting java 1.7. but android system runtime(dalvik jvm) does not know how to process those files which means dex tool wont process those files which belongs to 1.7 and it wont create classes.dex file..hope it will help somehow
From the error you have posted it seems the problem is only with the path settings.
Add the path upto the bin folder of your jdk - C:\Program Files\Java\jdk1.7.0_45\bin and restart the eclipse.
Please verify if your SDK Location in the Window->Preferences->Android points to the correct SDK path.
Download latest android bundle from http://developer.android.com/sdk/index.html.
and replace new sdk folder with old sdk folder from android bundle folder.
now it's may work.
Finally Reinstalled my OS and Installed JDK 1.6. Then I have added my updated SDK to my ADT. It works fine now.
I've had the same issue, and this solved it
