Eclipse newspaper "An error had occurred,see error log for more details. Java.lang.NullPointerException ", let me first tell you how I reported this mistake, I would like to open the Android project in the Res folder in the Layout folder in the. xml file, the error will be reported.

Then I went to search the Internet, and generally are the answers, there are some answers can not be scolded poured, so I do not dare to try to use the online method. Just try a "start" and "Run"----> "cmd" into the command prompt line, Then go to the Eclipse folder of the MyEclipse installation directory and enter Eclipse-clean. "But it doesn't work, and the others won't try.

I changed the working environment myself and tried to open the. XML layout file for other Android projects, so I can open it miraculously, so I know that this problem is a work environment, so I created a new folder as the working environment, import the project into the new environment And then open successfully. The problem is solved at this point.
