# Errors While Starting Studio

# Overview

Occasionally you may experience errors starting Studio. Here are some suggested solutions.

⚠️ Warning

See Switching your Workspace to help find your current workspace location

# Workspace in use or cannot be created, choose a different one

This can happen as a result of an improper shutdown of Studio. To resolve the issue, you need to delete a .lock file.

  1. Delete the file %WORKSPACE_PATH%/.metadata/.lock, and restart Studio

# An Error Has Occurred

These are errors pop up a dialog box, asking you to look at a log file

# See the log file /Users/....

Open the log file at the specified location. If you see messages like:

org.osgi.framework.BundleException: Exception in org.eclipse.core.resources.ResourcesPlugin.start() of bundle org.eclipse.core.resources.
...
Caused by: org.eclipse.core.internal.dtree.ObjectNotFoundException: Tree element 'XXX' not found.

It is caused by this (opens new window) bug in Eclipse, most likely due to a case where Studio quit or was closed unexpectedly, corrupting a particular file.

Steps to fix:

  1. Copy your whole workspace first, so that you are not risking your original files when you attempt these steps

  2. Delete the file %WORKSPACE_PATH%/.metadata/.plugins/org.eclipse.core.resources/.snap, and restart Studio

This will start Studio, but your workspace will most likely be missing your projects. This is okay--you can quickly reimport them

  1. File > Import > Existing Projects....

  2. Select the workspace directory from above, and finish the wizard

# Launching the Studio with -clean

If Studio does not appear to work properly, you can try and launch it with a -clean option.

  1. Follow the instructions here for adding a launcher argument.

  2. Add -clean to the launch arguments for Studio or Eclipse.

# How to stop Studio from loading a problem file

A file might be causing trouble when Studio is restarted because it is very large or in some way corrupted. There are a couple of ways you could prevent Studio from loading the file.

  • Rename the problem file. This means Studio can no longer find it and so will ignore the file on restart.

  • Delete the <studio_workspace>\.metadata\.plugins\org.eclipse.ui.workbench\workbench.xml file, where the state of workbench when exiting is saved. This means Studio will not preload any files that were open on the last exit.
