I've just installed android studio. For the first time when I run that after a short while (after showing a loading bar), It shows me this error. So I searched in Internet and I did Everything I could,(downloading the last version on Java, re-installing the Program and run it for the first time as administrator, Adding the system variable JAVA_HOME and etc.)but still it shows me a dialog with this information:
Internal error. Please report to https://code.google.com/p/android/issues

What should I do now only for running Android Studio?
Open the folder where you installed Android Studio:
ex: C:\Program Files\Android\Android Studio\bin
Find and edit idea.properties. You can edit this with use notepad++ or any similar application that allows text editing.
Add this line as the final in the file:
disable.android.first.run=true
Now run Android Studio again.
The Best and easy Solution for this is :
- Close Android Studio
- Turn off Internet connection and be sure of it.
- Start Android Studio. You will see a popup box with Cancel option in it. Then Click cancel.
Next Time you can Easily start Android studio even having an internet connection..
