Delete all content from the C:\Users\ user name \.android folder and restart Eclipse. The first method I still did not solve after the

In the development of Android, it should be said that most people have encountered this problem.The exact reason is unclear, and the introduction of too many projects in workspace may be one of the reasons.There are a lot of solutions to this problem on the web, and for myself, the following two methods really play a role:1. Delete the. Metadata folder in the current workspace directoryThe success rate of this method should be very high, but the cost

The Code is as follows: Ftpfile [] files = ftpclient. listfiles ();For (INT I = 0; I Ftpfile file = files [I];String filename = file. getname ();If (filename. Equals (remotefilename )){Size = file. getsize ();}} However, when listfiles ()
