Android SDK Content Loader failing with NullPointerException

The issue is in the your-avd-name.ini that is located at ...\<user-profile>\.android on your Windows machine (if you're Windows user). When any error occurs during the avd.ini parser, the Google ADT plugin tries to access a map that is null. The workaround is to delete the offending .ini file and recreate your avd(s).

I solved the problem by deleting the .android directory in my user profile.

Solution:

Step 1. Find the folder named: > .android

This folder can be located in your Windows user directory, for example in Windows 7/8:

C:\Users\YOUR_WINDOWS_USERNAME.android

Step 2. Delete this folder .android

Step 3. Restart Eclipse and it is OK now
