I have downloaded this early preview, I know that it's not stable and everything but I see no one complaining on the most populated forums and my copy of Android Studio doesn't even starts.
I have tried with both JDK 1.6 and 1.7 from Oracle in the PATH but it always fails ( i have JAVA_HOME set too )
and this alert shows up 3 times and the startup just freezes, this is the complete output of about the failed start.
there is also 0 real practical documentation for this SDK, so I don't even any idea what the requirements for this suite are.
Strange fact: there is this file Install-Linux-tar.txt in the root of the android studio folder that suggest to run this ./android studio.sh command from the bin sub-directory but there is no ./android in that subdir and the instructions make no sense at all.
Make sure that java is installed in /user/java and not another directory.
I had same issue and simply moving Java directory fixed this issue
(I found a Google answer in a few seconds..)
For the second remark, that's totally true: forget./android studio.h and simply use ./studio.h

Might be a beginner question, i'm new to android studio.
I need to write a simple .apk on java which will load a react web-app.
If the new version of the app crashes, I'd like to downgrade the .apk. I assume by downloading the older version and installing it.
How could I structure the code the proper way to do that?
I'm not asking for the whole source code, just some tips of code structuring.
This ap is not for the market but for internal use.
So the OS version is fixed, 7.1.
Thanks.
You need to set the apk version code correctly, most likely in your root build.gradle file.
If version code 1 is working and installed on your users devices, then apk with version code 2 is installed but crashes, you have two options:
Fix changes and submit to users as new apk version code 3 (they can
update to this version)
Have user uninstall app, and re-install previous apk with version code 1.

I have tried unchecking and checking that box inside windows-->preference-->compiler option-->Class file generation. Tried restarting the eclipse.But it didnt work. I am using "eclipse-jee-indigo-SR2-win32-x86_64". I have used src zip folder in jdk1.7.0_79.
I just want to write my own program, use map/list etc and debug through methods of these classes and see how it works internally.Please help
The message is complaining about your Java runtime not having debugging information. Attaching source does not fix this problem, it will only enable you to read the source. You didn't compile those classes using Eclipse, so the preference has no relevance. If you want to debug into rt.jar, you need to install and compile/run against a JDK, not a JRE, and even if you have a JDK installed, it sounds like that is not what is being used to run your Java Application. Check your Installed JREs preference page (hint: prefer only having JDKs there) and then your application's Launch Configuration to make sure it's using what you expect.

i've got an error in java because i had to reinstall windows.
Error occured during initialization of VM
I tried in CMD to use java and the exact same error occurs!
I reinstalled java jre and removed jdk, still nothing helped. Any idea on how to solve this?
To make sure that it was not working i searched for Bukkit and tried to run the server, the exact same thing happens.
When i tried java -version
According to the comments, the problem was with the PATH.
Go to your environmental variables and check if there is a variable pointing to java.exe in jre directory. Reinstalling jre should solve the problem but to avoid it you can try the following:
The variable pointing to C:\Program Files (x86)\Java\jdk<version> should be called JAVA_HOME and the path variable should be extended with %JAVA_HOME%\bin\ and %JAVA_HOME% itself. Then somehow it might have the advantage to javapath

I recently installed Mars Eclipse. I took the default install directory, c:\users\myname\eclipse\java-mars. Everything is installed and some projects checked out and working.
But I now wish I had installed it in c:\eclipse\java-mars. I am wondering how to change it? Please note I did searches but they all are how to move your workspace, not how to change the installation directory. My workspace can stay where it is. I suppose I could uninstall and delete everything, and reinstall into a new directory, but that is a lot of hassle.
You just have to move the eclipse folder to the new location. There's no need to change anything in the PATH variable because this thing is only needed by eclipse itself to locate the java environment.
Note:
If you have any third-party librarys inside the eclipse folder that are used by eclipse during it's runtime there may be an error because eclipse only stores an absolute path to them in it's config files. So in that case, you have to change the path to such libraries in the eclipse settings, I think at the same point where you have added them.

I reinstalled the jdk after the installation of the new operating system, and set the environment variable of the system accordingly. I also restarted the computer after the reinstallation and the setup of new environment variable. Still, i am not able to run any java programs on my computer.

if you install jdk and java SE correctly
2.then download netbeans from netbeans.org/downloads/. Make sure that you are downloading netbeans 8.0.1. it will automatically fix errors and install necessary file.
after installation go on Cmd and type Javac
follow will be the screen of cmd after running this specific command
enjoy java :)
