The java.io imports do resolve fine in other Android projects in the same workspace, and previously (I haven't used it for over a year) this library worked fine, too. Any ideas? java android eclipse share|improve this question asked Mar 14 '13 at 17:30 Wouter 1,32731531 Check the compiler compliance for the library project –Pragnani Mar 14 '13 at 17:31 http://stackoverflow.com/questions/15416186/eclipse-the-import-java-io-cannot-be-resolved Should it read import java.io.*; ? –Stephen C Mar 14 '13 at 17:32 Just restarting Eclipse helped me! :P –IronBlossom Dec 11 '13 at 6:45 add a comment| 1 Answer 1 active oldest votes up vote 46 down vote accepted Check your Eclipse preferences: Java -> Installed JREs. The one that you're using should be marked and it should be a JDK not just a JRE. Also check your project's build path: Right click on the project -> Properties -> Java Build Path Check in the "libraries" folder whether the JRE System Library is present and if not add it using "Add library"->"JRE System Library" and then select the correct one (from an installed JDK). share|improve this answer answered Mar 14 '13 at 17:33 Sarath Kumar Sivan 3,20911118 Thanks. That solved part of the problem - no idea why I have to add it, as other projects in the same workspace don't have it explicitly added and still work. Next problem is now the Google API which is explicitly present in other projects, not here, and I have some resolve problems there too. –Wouter Mar 14 '13 at 17:43 1 OK that part solved too: Add Library; Android Classpath Container; select itself; OK. Bizarre. –Wouter Mar 14 '13 at 17:45 @Wouter, worked for me too &ndash

they were there). I was always getting the message: import ClassName cannot be resolved. Where ClassName was my imported class. I'm using the MyEclipse Workbench 5.5.1 on Eclipse 3.2. Here are a few tips on how you can fix this (some worked for me, some didn't): ‘Clean' Your Eclipse Project: Go to Project > Clean in Eclipse [This seems to work for me] Refresh your project folder (right click on your project > refresh) Re-build your project Clean your builds (If using Ant or Maven - clean your builds) Recreate your project in Eclipse ‘Switch' Workspace - then Switch back (Eg Change to Debug, then switch back to Java) ‘Switch' Workspace - then Switch back (Eg Change to Debug, then switch back to Java) Remove and re-add your JRE: 1. Right Click on your project > properties 2. Click on the Libraries tab 3. Click on the JRE 4. Click remove, then OK 5. Repeat 1-3 again, but add the JRE again Hope at least ONE of those tips help!

I am getting the error : Exception in thread "main" java.lang.Error: Unresolved compilation problems: The import com.sun.net.ssl.internal.ssl.Debug cannot be resolved Debug cannot be resolved Debug cannot be resolved Debug cannot be resolved ----------------------------- I think the trouble is with jre version , at this error I had jre1.7, and when I used 1.5 this error was gone but a new error for Javax.swing was introduced. Almost wasted two days on it. If anybody can help, it would be appreciated
