Android studio isn't opening [duplicate]

Every time I run Android Studio, this loading screen pops up, but Android Studio stays here and doesn't load. It's like this following picture except that the loading bar is loaded all the way but stuck there. I am running Windows 10.
I have tried many things, including setting the system variables JDK_HOME to where my JDK is located and the same for JAVA_HOME. I have also set a path. I ran as admin many times and let AS through a firewall.
I have also restarted and reinstalled countless times.
The version of AS is 2.0, and I am running the latest versions of Java.
Any help?

Open file Android Studio setup directory/bin/idea.properties
Add disable.android.first.run=true to end
Restart Android Studio
PLEASE NOTE: This will break patch updating to the next version. We
now check full binary checksums on the whole installation to prevent
various install corruption bugs as well as to preserve application
signatures. Therefore, make a copy of this file first, and before
updating, put it back.

Please try the following method to fix that issue:
Find the folder of your AndroidStudio: based on the following directory
macOS: ~/Library/Application Support/Google/AndroidStudio[version]
Delete the AndroidStudio folder.
Restart
Ref:https://developer.android.com/studio/known-issues#studio-config-directories

In order to know how to debug the problem, I executed the bin\studio.bat script in the terminal and inspected the actual Idea exceptions in order to fix the problem.
For me, this was the issue:
ERROR - llij.ide.plugins.PluginManager - java.net.BindException: Address already in use: bind
java.util.concurrent.CompletionException: java.net.BindException: Address already in use: bind
This means the plugin manager is trying to listen on a port that is not available. Is something listening on that port? For me, it was the stupid "excluded ports" by Windows, so I simply stopped the service:
net stop winnat (as administrator), and confirmed that Android Studio started to work.
No need to re-install, delete precious configuration (and plugins, etc.). Just read the log provided by the bin\studio.bat script, and I was able to fix the issue.

After some google and questions over SO I found solution which states that I need to uninstall my Antivirus. I did that, but still the same problem.
May some one please suggest me over this.
Thanks.

Maybe your probleme is similar to this : Android Studio doesn't start, fails saying components not installed
Try to run it with administrator privilege.

Android Studio stuck while building application

I recently switched from Eclipse to Android Studio because I read that it is now the official IDE for Android application development. I downloaded and installed the latest version (1.0.2) for Windows. When using the program for the first time, I decided to create a test application to see if the program was working correctly. Unfortunately, it was not. Once I clicked the finish button to complete the New Project Wizard, A loading bar showed up that said Gradle: Build. This is where the program gets stuck. There is no error message and it appears that the program is running fine, however the build never actually completes. I am never given my MainActivity.Java class, or my activitymain.xml document. If I click the cancel button, the program freezes and I have to use the TaskManager to kill the program. If I re-enter the program and choose to open an existing project, my project will be there. However, upon trying to open the project, I am greeted with the same Gradle: Build loading bar.. I have been searching for an answer for the last 3 days and nothing has worked. Any help is greatly appreciated!
Things I have tried:
Simply letting the program sit for a while to see if it was actually downloading something and was just really slow. I let it sit for 45+ minutes before killing the program.
Uninstalling and re-installing Android Studio
Restarting my computer
Turning off my firewall (Kaspersky)
Running the program as an administrator
Connecting to a different network
Disconnecting my computer from any networks (to force the program to build in offline mode)
Manually downloading Gradle from the link that Android Studio attempts to use when it gets stuck and telling the program to use that file instead of downloading another one.
(I went to this link https://services.gradle.org/distributions/gradle-2.2.1-all.zip, downloaded the file, unzipped it, went to Gradle settings in Android Studio, checked the Offline work checkbox, and finally set the service directory path to my unzipped Gradle folder.)
Hopefully I have given enough information and made it clear what my problem is. If not please tell me what else I need to explain so I can get this issue resolved. Thanks!
Please note I am working on a 64 bit machine running Windows 8. Also, I use studio64.exe
to run the program.

From the discussion we had in the comments, it does not look like you have your gradle on your windows path.
Please change the below to point to your gradle install:
set GRADLE_HOME=C:\<installation location>\gradle-1.11
set PATH=%PATH%;%GRADLE_HOME%\bin
After this, verify that in the terminal running the following works:
gradle tasks
once you get this working, you will want to run the following in your project:
gradle wrapper
This will produce a .bat file which you can then use to run gradle through the wrapper, letting you support multiple native gradle installations.

Unable to download trace file

Whenever I switch to DDMS view and start method profiling, I get the following error message when I stop profiling:
Method Profiling Error:
Unable to download trace file:
Remote object doesn't exist!
This only happens with 1.6 and 2.1 AVDs, 2.2 and 2.3 work fine. I've been having this problem ever since the latest update to the Eclipse Android plugin. I'm using Eclipse 3.5.2 on Ubuntu 10.04 with Android Development Toolkit version 8.0.0.v201011171904-77661. Let me know if you need any more information.
Edit 1:
Logcat output
Edit 2:
The trace file is actually created on the sdcard and I can pull it with adb or from DDMS file explorer and view it in traceview. I just get the error message when I click on the "stop method profiling" icon and the trace file isn't automatically displayed. I tried deleting the AVDs and creating new ones, installing the latest plugin version, and reinstalling the plugin but the issue remains. I can live with it, but it'd be nice to get it working like it used to.

I've read that this method of profiling works only on Android 2.2 and higher. Sorry, can't find link now.
On lower versions you are still able profile via Debug.startMethodTracing(); ... Debug.stopMethodTracing();
Upd: check that you have properly mounted sdcard with read/write permissions and check that you have WRITE_EXTERNAL_STORAGE permission in your manifest file. May be problem in this, because beginning from Android 2.2 DDMS heap dump requests streaming directly out of the VM, removing the external storage requirement.
If you have all permissions, then post here logcat output please.
P.S. I've found a document that I mentioned.

I would check if you can download the file manually with adb pull for starters. At least them you know if there is a problem with the file access and you can also look at it with traceview externally.
In addition you might want to check if there is a bug regarding this feature and/or try the latest release available from aosp since the latest Android tools seem to have issues for a lot of developers.
Of course a clean reinstall or an install of an older version would also help you finding the problem potentially.

Android SDK beginner question

I'm a n00b developer at my second attempt to use the Android SDK. I'm
developing on the Mac platform and I've noticed that the latest
version of the SDK doesn't include anything except the tools (so I
have no plugins, no targets to choose from inside the package I
downloaded).
So I tried to use the Android SDK and AVD Manager to download and
install some, however, I got this error:
Failed to fetch URL https://dl-ssl.google.com/android/repository/
I went to the settings and checked the box to force fetching via HTTP,
but no result. I was suggested to look for a configuration file, but
couldn't find any.
Any suggestions? I'm dying to get my hands dirty with the SDK.

Whenever I've seen that error, I've just retried the download several times and eventually it went through. I've only run into it when I was behind a proxy, but that might not be your problem.

Here you have a Android tutorial, step by step.

Its means that you are behind a proxy.Go tools->options in your android SDK manager and enter your http Proxy server and port and it'll work.
