ClassNotFoundException using AndroidAnnotations
android, android-annotations
Solution
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>
These should have been generated for you as part of following the AndroidAnnotations install. Things to check --
Your ADT tools are up to date.
You ran `Project->Clean` after enabling annotations
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 --
- Refactor/rename project to TestAnnotations (eclipse imported as "MainActivity_")
- Enable annotation processing (needed to turn on `Enable project specific settings` and `Enable annonation processing` in `Java Compiler->Annontation Processing)
- Project->Clean
- Run it
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.
Problem
I trying to use AndroidAnnotaions, but getting `ClassNotFoundException` error in my project. For testing purposes, I created a new project with one `Activity` and I still getting the error. My files: 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 ``` 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; } } ``` These are the two files I changed from sample project created by Eclipse and followed these steps to add AndroidAnnotations to project: - Added `androidannotations-api-2.7.jar` to `libs` folder and to `build path` - Added `androidannotations-2.7.jar` to `compiled-libs` folder and to `Factory Path` - Marked `androidannotations-2.7.jar` in `Order and Export` tab. Here the stack trace when I launch the app: ``` 12-28 20:29:21.296: E/AndroidRuntime(30600): FATAL EXCEPTION: main 12-28 20:29:21.296: E/AndroidRuntime(30600): java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.rodrigora.testannotations/com.rodrigora.testannotations.MainActivity_}: java.lang.ClassNotFoundException: com.rodrigora.testannotations.MainActivity_ in loader dalvik.system.PathClassLoader[/data/app/com.rodrigora.testannotations-2.apk] 12-28 20:29:21.296: E/AndroidRuntime(30600): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1573) 12-28 20:29:21.296: E/AndroidRuntime(30600): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:1667) 12-28 20:29:21.296: E/AndroidRuntime(30600): at android.app.ActivityThread.access$1500(ActivityThread.java:117) 12-28 20:29:21.296: E/AndroidRuntime(30600): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:935) 12-28 20:29:21.296: E/AndroidRuntime(30600): at android.os.Handler.dispatchMessage(Handler.java:99) 12-28 20:29:21.296: E/AndroidRuntime(30600): at android.os.Looper.loop(Looper.java:130) 12-28 20:29:21.296: E/AndroidRuntime(30600): at android.app.ActivityThread.main(ActivityThread.java:3687) 12-28 20:29:21.296: E/AndroidRuntime(30600): at java.lang.reflect.Method.invokeNative(Native Method) 12-28 20:29:21.296: E/AndroidRuntime(30600): at java.lang.reflect.Method.invoke(Method.java:507) 12-28 20:29:21.296: E/AndroidRuntime(30600): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:867) 12-28 20:29:21.296: E/AndroidRuntime(30600): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:625) 12-28 20:29:21.296: E/AndroidRuntime(30600): at dalvik.system.NativeStart.main(Native Method) 12-28 20:29:21.296: E/AndroidRuntime(30600): Caused by: java.lang.ClassNotFoundException: com.rodrigora.testannotations.MainActivity_ in loader dalvik.system.PathClassLoader[/data/app/com.rodrigora.testannotations-2.apk] 12-28 20:29:21.296: E/AndroidRuntime(30600): at dalvik.system.PathClassLoader.findClass(PathClassLoader.java:240) 12-28 20:29:21.296: E/AndroidRuntime(30600): at java.lang.ClassLoader.loadClass(ClassLoader.java:551) 12-28 20:29:21.296: E/AndroidRuntime(30600): at java.lang.ClassLoader.loadClass(ClassLoader.java:511) 12-28 20:29:21.296: E/AndroidRuntime(30600): at android.app.Instrumentation.newActivity(Instrumentation.java:1021) 12-28 20:29:21.296: E/AndroidRuntime(30600): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1565) 12-28 20:29:21.296: E/AndroidRuntime(30600): ... 11 more ``` Anyone knows what I forgot? Eclipse should show generated classes by `AndroidAnnotations`? Thank you! EDIT Full code - bitbucket
