使用AndroidAnnotations了ClassNotFoundException [英] ClassNotFoundException using AndroidAnnotations

问题描述

我试图用AndroidAnnotaions，但在我的项目获得 ClassNotFoundException的错误。

I trying to use AndroidAnnotaions, but getting ClassNotFoundException error in my project.

出于测试目的，我创建了一个新的项目有一个活动，我仍然得到错误。 我的文件：

For testing purposes, I created a new project with one Activity and I still getting the error. My files:

AndroidManifest.xml中

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.rodrigora.testannotations"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="16" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.rodrigora.testannotations.MainActivity_"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

MainActivity.java

MainActivity.java

package com.rodrigora.testannotations;

import android.app.Activity;
import android.view.Menu;

import com.googlecode.androidannotations.annotations.EActivity;

@EActivity(R.layout.activity_main)
public class MainActivity extends Activity {

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }

}

这些是两个文件，​​我从Eclipse中创建示例项目发生变化，遵循这些步骤来AndroidAnnotations添加到项目：

These are the two files I changed from sample project created by Eclipse and followed these steps to add AndroidAnnotations to project:

1. 新增 androidannotations-API-2.7.jar 到库文件夹和构建路径
2. 新增 androidannotations-2.7.jar 到编译-库文件夹和工厂路径
3. 标记 androidannotations-2.7.jar 在订单和出口标签。

1. Added androidannotations-api-2.7.jar to libs folder and to build path
2. Added androidannotations-2.7.jar to compiled-libs folder and to Factory Path
3. Marked androidannotations-2.7.jar in Order and Export tab.

下面的堆栈跟踪，当我启动应用程序：

Here the stack trace when I launch the app:

任何人都知道什么，我忘了吗？ Eclipse应当由 AndroidAnnotations ？

Anyone knows what I forgot? Eclipse should show generated classes by AndroidAnnotations?

推荐答案

它看起来像你的Andr​​oindAnnotation生成的类都没有得到包含在构建。这里是你的.classpath似乎缺少行 -

It looks like your AndroindAnnotation generated classes are not getting included in your build. Here are the lines your .classpath seems to be missing --

   <classpathentry kind="src" path=".apt_generated">
               <attributes>
                       <attribute name="optional" value="true"/>
               </attributes>
   </classpathentry>

这些应该已经为您生成如下的Andr​​oidAnnotations安装的一部分。检查事项 -

These should have been generated for you as part of following the AndroidAnnotations install. Things to check --

• 您ADT工具是最新的。

• Your ADT tools are up to date.

您跑项目 - ＆GT;清洁启用后的注释

我能克隆你的回购，导入Eclipse，并得到一个干净的构建并使用以下步骤没有崩溃运行应用程序 -

I was able to clone your repo, import into eclipse, and get a clean build and run the app without a crash using the following steps --

1. 在重构/重命名项目TestAnnotations（日食导入为MainActivity _）
2. 启用注释处理（打开启用项目的具体设置需要和启用annonation处理在'的Java反编译> Annontation处理）
3. 项目 - >清除
4. 运行它

1. Refactor/rename project to TestAnnotations (eclipse imported as "MainActivity_")
2. Enable annotation processing (needed to turn on Enable project specific settings and Enable annonation processing in `Java Compiler->Annontation Processing)
3. Project->Clean
4. Run it

注意：的如果我做了一个进口和公正的重构，以得到一个干净的构建，但没有启用标注处理，我得到了你所描述的完全相同的行为。检查以确保您有项目的具体设置上，上注释，然后做一个干净的构建。

Note: If I did an import and just refactored to get a clean build, but did not enable annotation processing, I got the exact same behavior you describe. Check to make sure you have project specific settings on, annotations on, and then do a clean build.
