Eclipse - Failed to create the java virtual machine

Mostly eclipse user developer stick this error sometimes or many times during on his developing careers. So lets find out some solution, how to fix "failed to create the java virtual machine".

I have found some fine solution in stackoverflow and borrowing some answers here.

Solutions 1

------------

1. Open the eclipse.ini file from your eclipse folder,see the picture below.

2. Open eclipse.ini in Notepad or any other text-editor application, Find the line -Xmx256m (or -Xmx1024m). Now change the default value 256m (or 1024m) to 512m. You also need to give the exact java installed version (1.6 or 1.7 or other).

Like This:

-Xmx512m
-Dosgi.requiredJavaVersion=1.6

OR

-Xmx512m
-Dosgi.requiredJavaVersion=1.7

Then it works .

Solutions 2.
-----------

if solutions 1 is not working then try this:

Try removing the -vm P:\Programs\jdk1.6\bin lines.

---

Also, a general recommendation: set -Dosgi.requiredJavaVersion=1.6, not 1.5.

Solution 3
--------------

There are two place in eclipse.ini that includes

--launcher.XXMaxPermSize
256m

make it

--launcher.XXMaxPermSize
128m

Solution 4.

-------------------

if all the above solutions is not working then, try this:

Try to add



-vm D:\Java\jdk1.6.0_29\bin\javaw.exe

“Debug certificate expired” error in Android plugins in Eclispe

Problem: 
Error on Console

[2013-01-03 10:31:14 - androidTest]Error generating final archive:
Debug certificate expired on 1/03/13 12:35 AM!

Solution:- 

Solution 1:

Delete your debug certificate under ~/.android/debug.keystore on Linux and Mac OS X; the directory is something like %USERPROFILE%/.androidon Windows.
The Eclipse plugin should then generate a new certificate when you next try to build a debug package. You may need to clean and then build to generate the certificate.

Sometimes, it works for this solution, sometimes it doesn't. 

 Project-> Clean the project.->Close Eclipse-> Re-open Eclipse.

 Start the Emulator. Remove the Application from the emulator.
