Question

I just installed Eclipse-Classic 3.7.2 and android SDK. Also installed/configured eclipse with ADT plugin.

Now after following the steps in http://developer.android.com/resources/tutorials/hello-world.html to create a “Hello World” application I tried to run the application in Android Emulator. But this is throwing an error

Errors occurred during the build. Errors running builder ‘Android
Package Builder’ on project ‘HelloAndroid’.
sun/security/x509/X500Name

Can you please explain me what am I doing wrong here, or what do I need to fix for this error.

Thank you

The problem is related with the JVM you are working with, but also the certificate that have to be generated with the keytool from this JVM.

Here you are the commands i have used to solve this problem in my Linux Ubuntu v11.04 system:

1. I have installed the Oracle/Sun SDK 1.6 ( SDK not the JRE one ) on my computer.

2. I made this new SUN JVM the default with the following instruction

   sudo update-alternatives –config java

   Note A list is shown with all the available JVM on your system, select the SUN one.

3. Now you will be able to execute this command with the JVM provided by SUN:

   keytool -genkey -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android -keyalg RSA -validity 14000
   

Note You should delete the old debug.keystore file before you execute this command, or rename it as you wish.

Now that your system is up and running, then you need to configure your new JVM in Eclipse in order to compile with this new version.
