The summary of Eclipse error and corresponding processing method in Android development _android

In this paper, the eclipse error and its corresponding processing method in the development of Android are summarized in detail. Share to everyone for your reference, specific as follows:

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.

Attached: Online Other processing methods: "Lost the Android system library or conversion to Dalvik format failed with error 1 Error resolution"

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.

Error 4:

Java.lang.NoClassDefFoundError:org.apache.mina.transport.socket.nio.NioSocketConnector

The reason for the error: Do not know yet????

Workaround: Create a new project, copy the contents of the past, and pay attention to the package name.

Question 5:

How does the Chinese annotation garbled in eclipse solve??

Solution: Do projects are usually encoded with UTF-8, Eclipse's default encoding is GBK, you are in the Menu bar window, select the Preferences option, the first general workspace, selected right there is a text file Encoding, the default is selected on GBK, choose Other, List optional, select the bottom of the UTF-8, after the application and then import or create the project will not appear garbled.

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.

Question 7:

Java.lang.RuntimeException:Unable to instantiate activity ComponentInfo

Specific:

Java.lang.RuntimeException:Unable to instantiate activity componentinfo{com. Ipcamera/com. IpCamera.com.IpCamera.MainActivity}: Java.lang.ClassNotFoundException:com. IpCamera.com.IpCamera.MainActivity in Loader dalvik.system.pathclassloader[/data/app/com. IPCAMERA-1.APK]

Solution: Check the data, just know to lead in the project configuration file inside the path problem.

I hope this article will help you with the Android program.
