How can I install android studio?

I am using window 7 64 bit and i want to install android studio 2.0 or above version. I am able to successfully install android studio but when i launch it opens but it stuck as shown in below image. It not progressing i waited over long time to open next screen but it got stuck to this point.
I have already installed JDK8 64 bit and applied different solution like setting path as JAVA_HOME and SDK_HOME but it not resolve my problem.it does not also any error message through which i can find what is problem. So please help me how can i fix this issue.
After some research,I execute "studio.exe" in cmd from the path C:\Program Files\Android\Android Studio\bin. and i found below error message.But give any error on running studio64.exe. But problem is same it not progressing, it got stuck as above screen for more than 1 hour. Please Anybody tell me how to resolve it.

64-bit os and 64-bit java install? You want to open studio64.exe, not studio.exe (the 32-bit version). studio64.exe is in the same folder at studio.exe.

The problem may be with your processor speed, your RAM size or the file could be corrupt. If not, Did you download from the internet? if yes, what version?

I think you got JDK8 with 64-bit, but the android studio is running on 32-bit. I think you should install JDK with 32-bit instead of 64-bit.

Unable to install java on windows 10

Fresh installation of Windows 10 Home Build 10586.
Trying to install java, file jdk-8u101-windows-x64.exe.
After running the installer, as administrator, in the task manager appears for 2 seconds "Java Platform SE binary" and then it disappears with no error window appearing.
Xamarin installer tried to install jdk-7u79-windows-i586.exe but was also unable returning "JDK installation exited with error code: 123".
I boot also in safe mode and tried with no luck.
Any ideas of what is happening?

User account name had special characters (greek) and this caused the problem.
Creating a new user account with english characters solved the problem.

If you jdk install is C:\Program Files\Java\jdk-11.0.2:
SET JAVA_HOME=C:\Program Files\Java\jdk-11.0.2
SET Path=%PATH%;C:\Program Files\Java\jdk-11.0.2\bin;

Eclipse opens and then immediately closes after graphic appears

When windows installed updates, it closed my eclipse and corrupted the workspace or something. When I try to start eclipse I get the error:
I have already tried most of the google solutions. I tried deleting the plugins folder, and it still does the same thing. I tried adding the --clean option to the eclipse launcher, and it still crashes. If I delete the org.eclipse.e4.workbench folder, it still does the same behavior. When I try to start eclipse it shows the launcher logo for about a quarter second, and none of the above solutions fixed my problem.
Any other ideas?
Thanks,
The workspace exited with unsaved changes in the previous session; refreshing workspace to recover changes.

Step 3: eclipse -clean -clearPersistedState
Done!

Just Uninstall the latest Java updates from ControlPanel->Programs and Features
and Re-Open Eclipse .

SOLUTION IS SIMPLE
Firstly you wil come across this issue if you have uninstalled Java versions from system uninstall window. eg., I uninstalled Java 8 u151 from my machine and downloaded and installed Java 8 u152. Then it was opening with splash screens for few seconds.
Quick Fix is:
Undo all your java version changes.
Uninstall 152 for exammple and install the original 151 version. This fixed my issue.
DONT FOGET TO COPY ECLIPSE folder TO c:\program files folder.

Eclipse run fail - Error code 13 and Failed to load JNI shared library

I'm having problems to run eclipse in my job - at my home desktop I got everything as a 64 bit version. What I did was copy the folders to my job desktop and it doesn't. I checked the architecture here and it's 64 bits too. The failure come from both sides:
If I set my virtual machine as:
C:\jre7\bin\javaw.exe
I receive the error from code 13.
If I set the virtual machine as
C:\jre7\bin\client\jvm.dll
I receive the error from "Can't load shared library"
my source researches were :
Failed to load the JNI shared Library (JDK)
Eclipse reported "Failed to load JNI shared library"
Cannot run Eclipse; JVM terminated. Exit code=13
Can't start Eclipse - Java was started but returned exit code=13
Eclipse crashes at startup; Exit code=13
Resuming:
Home desktop - Windows 64, JRE 64, Eclipse Juno 64
Job desktop - Windows 64, JRE 64, Eclipse Juno 64
Anyone got any idea of what I could do? Cos with my research everything I tryed was in vain.

Try installing the Java Development Kit JDK.
You probably only have the JRE installed. This has happened to me before and thats how I fixed it.
http://www.oracle.com/technetwork/java/javase/downloads/index.html

I have encountered this issue. My reason is I have some other softwares(like oracle) includes some version of JVM, but don't have JNI. And the installation of that kind of software add something to my Path variable. Then eclipse search that path and failed.
Please examine your Path enviroment variable and see if exists any wrong path in front of the correct JVM path, or just try to move your JVM bin path in front of all the others.

Android SDK suddenly stopped working

After a couple of months with no Android development, I ran the SDK Manager yesterday, and upgraded from r16 to r18. After that upgrade, everything stopped working. I downloaded a fresh copy of the SDK tools from Google. The Windows installer complains there's no Java installed (the solution here , which used to work before, doesn't work).
I downloaded the ZIP file instead and put it in the right place. Running SDK Manager.EXE does nothing (it just returns immediately to the command prompt). Running tools\android.bat displays an error complaining "Failed to convert path to a short DOS path: c:\windows\system32\java.exe", and then suggests I install Java.
I'm running Windows 7 64-bit, with Java 1.7 (64 bit) properly installed (Eclipse runs well, the Android tools r16 ran very well until yesterday). c:\windows\system32\java.exe exists and works as it should.
What am I doing wrong?
UPDATE: I found an old r16 setup around. I installed it and everything went back to normal.

I put this one aside for a while, but now I had to get it back running. I didn't want to install a 32-bit Java VM alongside the 64 bit one I have.
I found the culprit. in android_sdk\tools\lib there's a batch-file called find_java.bat. It calls find_java.exe -s to find a list of potential Java locations. Running the exe file like this returns the error I've been seeing:
Failed to convert path to short DOS path: c:\windows\system32\java.exe
-s stands for short. Running it without the -s causes find_java.exe to work, causing find_java.bat to work, causing everything else to work. So the fix was to edit find_java.bat, and remove the -s .
I honestly don't know what Google is thinking.

My fix was to remove /bin from my JAVA_HOME, as in C:\Java\jdk1.6.0_26\bin --> C:\Java\jdk1.6.0_26\
I'm running 64bit java on W7.

This is just a guess, but I advise you to install JDK 6. It is said in the SDK requirements that you have to use it. I remember that I installed JDK 7 and I had some kind of trouble with it too.
Also it is safer to use the 32-bit version.

You need to also update the Eclipse plugins via Help > Install New Software.

I was able to fix same like problem by adding the jdk path to PATH variable in environment variables.
