Eclipse error and corresponding processing method accumulation

Error 1:
Conversion to Dalvik format failed with error 1

The reason for the error: The reason is that I accidentally imported Java Mina in the Android project, the result of a running program reported this error.
Workaround: Remove the Mina package used in Java and just OK.
Summary: In the future when you encounter this error, remember to remind yourself that it may be due to their own guide to the wrong package.

Error 2:
Exception in thread "main" java.lang.noclassdeffounderror:org/slf4j/loggerfactory

The reason for the error:
The exception occurs inside the main thread. This class is not found in the Javalang bag. That is, there are no packages to import accordingly.
This error, which I found in Java to implement a communication conversation with Mina, was due to the fact that the following two packages were not imported.
Workaround: Import the package Slf4j-api-1.6.4.jar and Slf4j-nop-1.6.4.jar two packages.
Android and Java inside the Mina bag I put in my blog resources have, want to use words can go to download.
Summary: Remember to import the package problem, especially when you are not with the Java package, you must remember. There is a mistake, directly copied to Google, find solutions.

Error 3:
[2012-05-18 20:27:23-Here is your project name] The connection to ADB are down, and a severe error has occured.
[2012-05-18 20:27:23-...] You must restart ADB and Eclipse.
[2012-05-18 20:27:23-... Please ensure the ADB is correctly located in ' E:\Program Files\andriod_sdk\platform-tools\adb.exe ' and can be executed.

The reason for the error: Because the hint is that the ADB connection has been closed, a service error has occurred. That is, you should close the ADB process and start eclipse anew.
Workaround: Open Task Manager, end the Adb.exe process directly in the process, note that there may be multiple adb.exe processes, and remember to close them all.
Summary: When you do not know how to deal with the error, copied to Google should be able to solve the problem.

Question 6:
Eclipse Import Package prompts setting build path has encountered a problem
Tip: ' Setting build path ' has encountered a problem,could not write file D:\\workspace\aaa\.classpath
Error reason: is the path problem
Solution: Locate the hidden. classpath file in the project, and modify its hidden properties to be visible.

This type of error is common when you copy a Java project from a machine's eclipse workspace to another machine's eclipse work environment.
